ATG9 regulates autophagosome progression from the endoplasmic reticulum
Plant Science Research Weekly, Research0 Comments
/
The autophagosome, a cellular compartment involved in the turnover of macromolecules, contributes to nutrient homeostasis, stress resilience and defense. Although several proteins have been identified as contributing to autophagosome formation and function, the precise origins of the autophagosome have…
S-phase checkpoints regulate appressorium-mediated plant infection by rice blast fungus
Plant Science Research Weekly, ResearchThe rice blast fungus Magnaporthe oryzae causes a devastating disease of rice that can reduce harvests by 30%. Infection of plant tissues by the fungus requires the formation of an appressorium, a specialized structure that builds up sufficient pressure to burst through the plant cuticle. Previous work…
Review: The many roles of AVP1, a H+-PPase ($)
Plant Science Research Weekly, ResearchThe AVP1 gene encodes a proton-pumping pyrophosphatase (H+-PPase) localized to the vacuolar membrane, which means that it pumps H+ into the vacuole using energy stored in pyrophosphatase (PPi). The direct consequences of its action are the acidification of the vacuole and the removal of PPi from the…
J. Exp. Bot. Special Issue: Making Connections: Plant Vascular Tissue Development
Plant Science Research Weekly, ResearchThe Journal of Experimental Botany has a special issue on vascular development that features several outstanding review and opinion articles. Topics include Evolution of Conducting Cells, Regulation of Vascular Cell Division, overviews of hormones, peptide signals, receptors and transcription factors…
Reviews: Seed dormancy and germination ($)
Plant Science Research Weekly, ResearchA pair of reviews in J. Exp. Bot. covers aspects of seed dormancy and germination. Steinbrecher and Leubner-Metzger (10.1093/jxb/erw428) provide an excellent introduction to materials science including stress-strain curves and Young’s Modulus, which they then apply to an understanding of the biophysics…
Metabolic control of tobacco pollination ($)
Plant Science Research Weekly, Research, Research BlogA germinated pollen grain extends a pollen tube through the stigma and style of the flower to deliver two sperm cells to an ovule. Tip-directed growth of the pollen tube requires a large energy input, but how does the pollen tube obtain energy while growing through the flower tissues? Goetz et al.…
Review: Volvox as a developmental model
Plant Science Research Weekly, ResearchMatt and Umen introduce the multicellular green alga Volvox carteri as a model for developmental studies. They provide an overview of embryonic patterning including the role of asymmetric cell divisions, inversion, (a process with some similarities to vertebrate gastrulation), and the role of cell size…
Previewing Pollen Biology special issue of Plant Physiology
