IN BRIEF by Gregory Bertoni [email protected] Autophagy, or "self eating," is the process cells use to consume unwanted intracellular structures such as damaged organelles, excess membranes, and unneeded cellular proteins (Mizushima and Komatsu, 2011). Typically, the unwanted structure becomes surrounded…

IN BRIEF by Jennifer Lockhart [email protected] The interior of a plant cell is supported by the actin cytoskeleton, a complex network of yarn-like fibers whose form changes as the cell develops, grows, and divides. Actin fibers readily come apart (sever) and join back together, depending on the…

IN BRIEF: Nancy R. Hofmann [email protected] Plant development and responses to the environment hinge on the ability to target proteins to different areas of the plasma membrane within a cell. Indeed, the establishment of polar distributions of proteins such as PIN auxin transporters is among the…

IN BRIEF by Kathleen L. Farquharson [email protected] Limiting shoot growth is an important survival strategy for plants during times of drought; smaller leaves mean that less water is lost through transpiration and more is retained in the soil. As drought stress restricts both cell division and…

IN BRIEF by Jennifer Lockhart [email protected] DNA is sculpted by several types of epigenetic modifications with profound effects on gene expression, development, and stress responses. Much less is known about the more than 100 chemical modifications shaping plant RNA, a topic explored in the newly…

Due to plant cells’ shared walls and immobility, cell division, differentiation and expansion must be tightly regulated across space and time. The six members of the PLETHORA (PLT) transcription factor family distribute in gradients through the root tip and are largely responsible for its developmental…

Recently, we’ve been profiling first authors of Plant Cell papers that are selected for In Brief summaries. Here are the first-author profiles from the December issue of The Plant Cell. Yao-Pin Lin, featured author of Identification of Chlorophyll Dephytylase Involved in Chlorophyll Turnover in Arabidopsis Current…

Although most flowering plants produce flowers with male and female parts, there are exceptions which are broadly classified as dioecious (two houses; each individual is male or female, usually associated with the presence of a sex chromosome) and monoecious (one house, separate male and female flowers…
