What We're Reading: July 28th

This week’s edition of What We’re Reading is guest edited by Dr. Bhavisha P. Sheth, who is currently working as a DST- Science, Technology and Innovation Policy Postdoctoral Fellow at the Entrepreneurship Development Institute of India (EDII), India. Her current research work focusses on Policy research…

From Light to Food – Organization of Photosynthetic Complexes

MacGregor-Chatwin et al. map the cellular organization of photosynthetic protein complexes http://www.plantcell.org/content/29/5/1119 Life on Earth depends on photosynthesis, the source of all of our food, oxygen, and most of our energy. Two pigment-protein complexes called Photosystems I and II…

Maize Meristem Matters

Tsuda et al. explore the function of BLH transcription factors in maize meristems Plants have specialized tissues at the tips of roots and shoots called meristems. Meristem cells are what keep the plant growing; they are undifferentiated cells that continue to divide, providing new cells for growth.…

How Rice Seedlings Emerge from Soil

Xiong et al. explore the action of plant hormones that control how rice seedlings emerge from the soil http://www.plantcell.org/content/29/5/1053 By Qing Xiong, Bao Ma, and Lu Xiang Flowering plants begin their life cycle as a seed beneath the soil surface. With adequate water and the right temperature,…

Funding Opportunity: NSF Solicits Proposals to Expand INCLUDES National Network

On July 14, the National Science Foundation (NSF) released a Dear Colleague Letter (DCL) soliciting proposals to expand the Inclusion across the Nation of Communities of Learners of Underrepresented Discoverers in Engineering and Science (INCLUDES) program.  The DCL invites proposals for Early-concept…

Using Metabolism to Improve Maize Breeding

Cañas et al. study the relationships between maize leaf metabolism and grain yield to identify putative markers for breeding http://www.plantcell.org/content/29/5/919 By Rafael A. Cañas, Peter J. Lea and Bertrand Hirel In crops, several metabolic pathways are involved in the control of biomass…

Review: Uncovering gene regulatory networks controlling plant cell differentiation ($)

The transparency and simplicity of the Arabidopsis root apex has made it an excellent model through which to understand the processes that lead from undifferentiated meristem cells to mature root tissues. Drapek et al. review the gene regulatory networks (GRNs) that underlie the development of the endodermis…

Update: Shining light on the function of NPH3/RPT2-like proteins in phototropin signalling

Blue light regulates diverse functions including phototropism and chloroplast movements. Christie et al. summarize recent updates in understanding the signalling pathway between light perception by phototropins and downstream responses. They describe the central roles for the 33 members (in Arabidopsis)…

Review: The evolution of calcium-based signalling in plants

Calcium signalling is a ubiquitous process in plants and other organisms. Transporters at the plasma and vacuolar (tonoplast) membranes control entry and exit of calcium ion into the cytoplasm, and it is the cytoplasmic calcium level ([Ca2+]cyt) that affects cellular responses, as calcium-binding proteins…
