What is the name of this plant? It was found in a village in Bangladesh, in the month of February.
I believe this plant may be Rotala rotundifolia
Quoting from Wikipedia,
It is a common weed in rice paddies and wet places in India, China, Taiwan, Thailand, Laos, and Vietnam, and has been introduced to the United States.
This makes sense, as Bangladesh is located near both India and China.
The emerse form has rounded leaves, the submerse leaves are narrow lanceolate. It is very variable dependent on light and environmental conditions. Under strong light, the leaves can become almost wine red. It has pale pink flowers.
International plant systems biology
This EMBO Workshop on international Plant Systems Biology (iPSB) is the central gathering of plant systems biology researchers from across the world. Climate change poses unique challenges for how to feed and power humanity without further degrading the environment. Plant science therefore is a key discipline in meeting the challenge of adapting food and energy production and society to the consequences of climate change. Towards the understanding of complex genotype-phenotype relationships, systems biology approaches, i.e. global omics and quantitative modelling, need to complement classic genetics and cell biology. Building on the success of the first iPSB in Roscoff in 2018 and with having to postpone our plans for Venice, Italy in September 2020, we are now delighted to be able to offer the second iPSB virtually. There will be invited talks, talks selected from abstract submissions, an online poster session and time to network at virtual tables.
As systems biology has many facets it is important to bring together researchers taking a variety of approaches, in order to mesh these directions towards a deeper understanding of biological systems. Each of our six workshop sessions is accessible to non-experts to ensure cross-fertilisation since there are strong but not yet fully realised links between researchers across systems biology. We particularly encourage applications from early career researchers and the size of the meeting offers a tremendous chance for interaction, building a future for this exciting discipline. Around half of the oral presentations will be selected from abstracts.
- Session 1 - Gene Regulatory Networks
- Session 2 - Metabolic Networks
- Session 3 - Synthetic Biology
- Session 4 - From Single Cell Genomics to Tissue Modeling

Plant Biology for Kids
What You'll Find on This Page
I am a huge fan of teaching plant biology for kids – they have a natural fascination about the world around them, and they remember scientific terms easily. Spring is a great time to start gardening with kids, and you don’t have to wait for spring temperatures to get started!
Plant biology is also an activity that pairs well with this week’s Virtual Book Club for Kids theme: Garden. The Tiny Seed by Eric Carle is this week’s featured book. The Curious Garden is another wonderful picture book for this theme.
An Introduction to Photosynthesis
Having live plants in your home is a wonderful way to teach kids about the importance plants attach to sunlight. You can use a seedling to show how plants follow the sun, or larger plants like these bean plants! If you look at the photo, you will see that the plant’s leaves are turned so that they can absorb as much sunlight as possible. Turn the planting box, and the leaves will turn again to follow the sun! Chlorophyll is a pigment that makes the leaves green – and it absorbs the sunlight, which it needs for photosynthesis!
A very basic explanation of photosynthesis is that the plant takes the sunlight that it has absorbed through its leaves along with carbon dioxide it gets from the air and water that it gets though its roots. It combines these ingredients to create the sugar that the plant needs to grow. You can use any plant in any container to teach this lesson, but thinner, see-through planters like the one above are cool because you can see root systems so well. A zip lock bag also works – there is no need to get fancy, but this was a birthday gift that Emma really enjoyed last year.
You can also plant seeds in a jar, or even a simple Ziploc bag.

From Penn State to Pullman, plant biology is root for WSU professors
Plant biologists Andrew McCubbin and Sian Ritchie, pictured here, moved to Pullman in 2001. They are both faculty in WSU’s School of Biological Sciences.
ALEXANDRIA OSBORNE, Evergreen reporter
June 9, 2021
Plant biology was the factor that lured two WSU faculty members all the way from across the pond to Pullman, with a stop in between.
Andrew McCubbin, associate professor in WSU’s School of Biological Sciences, and his wife Sian Ritchie, SBS clinical assistant professor, are both plant biologists at WSU.
McCubbin said he started showing interest in the discipline when he was 13.
“For me, it was hearing about the development of high yielding lines in the green revolution,” he said, “ironically in a geography class.”
The couple is originally from the United Kingdom, but came to the U.S. in the mid-90s and lived near The Pennsylvania State University, McCubbin said. He moved to the U.S. in February 1994, while Ritchie moved in March 1995.
“ One of the faculty … knew I was at Penn State when Sian got her position there a year later and suggested she [look] me up when she got there,” he said.
McCubbin said he met Ritchie at Penn State, but the two traveled separately and worked in different labs. They were both doing their post-doctoral research at the time, and they earned their doctorates at the university.
They ended up moving to Pullman in 2001, he said.
McCubbin said they did not want to end up in the South and wanted to be at a state with a coastline when moving around.
“ We had enjoyed living in Penn State. It’s quite similar to Pullman, in a way,” he said. “[Penn State is] midway between Pittsburgh and Philadelphia, but it’s a small college town.”
Ritchie said the outdoor aspect of Pullman drew their attention to the town as well.
“There’s Rockies nearby and Oregon, so the geographic locations [were nice],” she said. “And WSU … really is well known for its plant biology.”
Ritchie said she enjoys working with plants because they are interesting but underestimated as well.
“People think they just kind of sit there and do photosynthesis and that’s it,” she said. “But they have all this interaction with the environment and other organisms that we don’t necessarily appreciate until you dig into it and realize just how cool they are.”
The couple has two sons, Ritchie said. They did not push science on their sons too much, but the family would regularly talk about the subject at the dinner table.
“They’re both heavily into music and things as well,” McCubbin said. “We’re enthusiastic about science, and that probably had an influence on them.”
Ritchie said their sons work hard on their schoolwork and do well in all areas.
“The older one is not so biology oriented he’s doing physics,” she said. “He likes science, but biology is too messy.”
Below is a brief synopsis of my "walk through life" (curriculum vitae). If you would like to have my complete CV, please email me and I will send it. All of my publications can be seen HERE. One could categorize me as an avid botanist who loves the combination of laboratory and field work. My research often takes me to distant parts of the world where new cultures and environments can be appreciated. I enjoy hiking, canoeing, camping, wood sculpture, gardening, photography, and guitar.
In 1974-75, I conducted my first year of undergraduate study at Illinois State University in my home town of Normal, Illinois. After replying to an advertisement to conduct floristic work in the Great Dismal Swamp as an NSF Undergraduate Research Participant, I spent a summer working mostly alone but under the direction of Dr. Lytton Musselman at Old Dominion University, Norfolk, VA. Although I began this project knowing about two plant scientific names, I finished knowing over 500, thus my interest in botany was born. I then returned to Illinois and finished my undergraduate work in the Botany Department at Southern Illinois University Carbondale, receiving a bachelor's degree in 1977. It was also in this year that my first scientific article on the flora of the Great Dismal Swamp was published in the journal Rhodora (Nickrent, Musselman and Levy 1977).
Masters Program at Old Dominion University
Having had an excellent experience with Dr. Musselman, I returned to Old Dominion University (ODU) and began working on ferns (Dryopteris). During the summer of 1978, an opportunity arose to work on the parasite witchweed (Striga) that had been introduced to North Carolina. This work, funded by the US Dept. of Agriculture, sparked my interest in parasitic plants. In 1979 I received my M.S. degree in Biology from ODU.
Doctoral Program at Miami University
After a brief time at the University of Virginia at Charlottesville, I switched to a program better suited to my interests - the Department of Botany at Miami University, Oxford Ohio. There I began pursuing a Ph.D. with Dr. W. Hardy Eshbaugh (Botany) as my major advisor and co-advised by Dr. Sheldon Guttman (Zoology) whose expertise was isozymes. Although I originally began working on haustorial development in a hemiparasitic member of Orobanchaceae (Dasistoma), following a conversation with Dr. Charles Werth, I wrote a doctoral dissertation improvement grant to examine systematic relationships in Arceuthobium (dwarf mistletoes, Viscaceae) using isozymes. This grant was funded in 1982, so the next two years were spent collecting mistletoe seeds from Mexico through the western US and Canada. In 1984 I received my Ph.D. in Botany from Miami University.
Professor Position at University of Illinois
From 1984 to 1990 I was an Assistant Professor and Director of the Herbarium (ILL) at the University of Illinois at Urbana/Champaign. In 1986 I became an Affiliate Professional Scientist with the Illinois Natural History Survey. For most of my time I utilized isozymes to examine systematic and population genetic questions in parasitic and non-parasitic plants. But later Dr. Carl Woese and other College of Science faculty established a laboratory to conduct ribosomal RNA sequencing. During this pre-PCR time, rRNA was extracted, cDNA produced with reverse transcriptase, and that template sequenced using the dideoxy-nucleotide (Sanger) method. In 1990 my first molecular phylogenetics paper on the sandalwood order (Santalales) was published (Nickrent & Francina 1990) and I also received funding for a major grant from the National Science Foundation entitled " Molecular Phylogenies of Parasitic Flowering Plant s". Despite these positive career milestones and support from my Department, I did not get a positive promotion decision from the College of Science . T hus began my search for another academic position.
Professor Position at Southern Illinois University
Fortunately, a position for an Assistant professorship in Plant Biology at SIUC was available, so I interviewed for the job at my alma mater in Carbondale. In 1990 I joined the faculty in Plant Biology (the Department had recently changed its name from Botany). During this time my main laboratory methodology switched from working with rRNA to DNA and the polymerase chain reaction (PCR) made the job of sequencing genes infinitely easier. In 1994 my lab documented increased rates of gene evolution in parasitic plants (Nickrent and Starr 1994) and one of the first species-level molecular phylogenies using nuclear ITS (Nickrent, Schuette & Starr 1994) on none other than my beloved dwarf mistletoes, Arceuthobium. It was also about this time that my lab moved from the Life Science II building to new facilities in Life Science III. In 1994 I received another NSF grant entitled " Molecular Phylogenetic Studies of Parasitic Plant s" that helped fund ongoing research on these plants.
As an Associate Professor (1994-2003), my research program expanded to examine many groups of parasitic plants, including those that lack photosynthesis (holoparasites). This period was also marked by numerous collaborations with colleagues within and outside SIUC. It was particularly gratifying that in 2004, after 25 years, I was able to collaborate on a project with Lytton Musselman, and produce a web article on parasitic plants hosted by the American Phytopathological Society (update 2016 HERE). In 2003 I was promoted to Professor. My work on Rafflesia in the Philippines was supported by a grant from the National Geographic Society in 2008. This began a fruitful collaboration with colleagues Julie Barcelona and Pieter Pelser (both of whom also attended Miami University!) that continues to this day. In 2010 we launched Co's Digital Flora of the Philippines (HERE) which is the only complete and continually updated listing of the plants from this biodiversity hotspot. That website is dependent upon another, launched in 2006, called PhytoImages that is served at SIUC but runs on software developed by Kevin Nixon and collaborators at Cornell University. This site presents photographs and metadata for all groups of plants worldwide.
As indicated by my title "Emeritus", I indeed did retire in 2014, but I continue working on a number of research projects. I was fortunate to work with some amazing folks over several years that culminated in 2016 in the publication of my treatment of Santalales for the Flora North America. The days of PCR amplifying individual genes are gone given that today Next Generation DNA sequencing can provide whole plant genomes. I am currently collaborating with colleagues within and outside my university using such data. It is such an exciting time to be a scientist and a perennial student!
