Due to its ease of use and noninvasive nature, variable chlorophyll fluorescence techniques have become increasingly popular for estimating photosynthetic parameters. Most measurements of variable chlorophyll fluorescence in complex plant tissues and surface-associated cell assemblages (e.g. biofilms)…

Plant shoot branching is determined by apical dominance, a process in which the apical bud (shoot tip) inhibits the outgrowth of axillary buds further down the stem to control the number of growing branches. In response to this inhibition, plants have evolved rapid long-distance signaling mechanisms…

Vesicle traffic to and from the plasma membrane plays an integral role in regulating protein localization and activity, membrane composition, and cell surface area. Clathrin is a structural protein that forms a lattice-like complex composed of two H chain subunits (CHC1 and CHC2) and two light chain…

Pattern formation in multicellular organisms is the result of coordinated cell division and cell fate determination. In animals, cell fate is determined mainly by a cell lineage-dependent mechanism, whereas positional information is thought to be the primary determinant of cell fate in plants. Currently,…

Geraint Perry from GARNet (@GARNetweets) interviewed Emily Larson (@erlarson_phd), author of "Clathrin Heavy Chain subunits coordinate endo- and exocytic traffic and affect stomatal movement" published recently in Plant Physiology. Emily Larson from the University of Glasgow talks clathrin, balloons…

By Alexandre Huchelmann, Marc Boutry, and Charles Hachez Abstract Multicellular glandular trichomes are epidermal outgrowths characterized by the presence of a head made of cells that have the ability to secrete or store large quantities of specialized metabolites. Our understanding of the transcriptional…

Improving photosynthetic efficiency is a major target for increasing crop biomass production and yield potential. The canopy photosynthetic efficiency, which is determined by leaf area index, canopy architecture, and leaf photosynthetic properties, plays an important role in determining biomass accumulation.…

Calcium (Ca2+) is an important cellular second messenger for diverse developmental processes and environmental responses in both plants and animals. Transient increases in cytosolic Ca2+ are activated in plants during a host of environmental and developmental processes, including root growth, stomatal…
