Plants undergo photosynthesis in leaves to produce carbohydrates sucrose and starch. The sucrose is transported to other parts of the plants via sugar transporters called SWEET proteins. In addition, certain plant pathogens activate SWEET genes to invade their host. As shown in this paper, during bacterial blight of cotton (BBC) disease, in cotton GhSWEET10 is […]
The effects of climate change on agriculture to human health have been well discussed in both scientific and public domains. In plants, changes in climate might affect interactions between the plants and their insect pollinators due to variable availability of pollinators in severe weather conditions, thus affecting reproductive success of plants and crop yield. In […]
Animals and plants have divergent sets of blue light receptors, called Cryptochromes. However, green alga Chlamydomonas has both animal-like and plant cryptochrome (pCRY). The presence of multiple cryptochrome suggests specific roles in different pathways in respective organisms. In this paper, Müller et al explore the biological functions of pCRY using a mutant with reduced pCRY […]
Gene expression is regulated at multiple levels such as genome, transcription, RNA processing and nuclear export, translation, and post-translation. Functional mRNA levels are regulated at transcription stage where RNA polymerase II (RNAPII) controls initiation and elongation of mRNA. In particular, the C-terminal domain of RNAPII defines the elongation phase along with Transcript Elongation Factors (TEFs). […]
Throughout plant life cycle, from germination till reproduction, every event is regulated by a highly complex network of hormones. Unlike animals where hormones are synthesized in specific glands, each plant cell is able to produce hormones. However, hormones are synthesized in specific organs in plants. Recent advancements in tools have enabled plant scientists to study […]

Eukaryotic pathogens are responsible for devastating plant diseases that threaten food supplies globally – think potato blight caused by the oomycete Phytophora infestans, rice blast caused by the fungus Magnaporthe oryzae, and wheat stem rust caused by the fungus Puccinia graminis f. sp. tritici. These pathogens secrete effector proteins that condition the host cells for […]
This week’s What We’re Reading is curated by Sridhar Gutam, Senior Scientist, Indian Council of Agricultural Research and Nidhi Sharma, Research Specialist, Stanford University. Nidhi Sharma is a researcher in Dominique Bergmann’s lab at Stanford University. She graduated from The University of Texas at Austin and did post-doctoral work with Dr. Kathy Barton at Carnegie […]
