METACASPASE9 modulates autophagy to confine cell death to the target cells during Arabidopsis vascular xylem differentiation
We uncovered that the level of autophagy in plant cells undergoing programmed cell death determines the fate of the surrounding cells. Our approach consisted of using Arabidopsis thaliana cell cultures capable of differentiating into two different cell types: vascular tracheary elements (TEs) that undergo programmed cell death (PCD) and protoplast autolysis, and parenchymatic non-TEs that remai...
متن کاملDevelopmental expression and perturbation of arabinogalactan-proteins during seed germination and seedling growth in tomato.
Arabinogalactan-proteins (AGPs) are a family of highly glycosylated hydroxyproline-rich glycoproteins present throughout the plant kingdom. A synthetic chemical reagent, (beta-D-Gal)3 Yariv reagent, specifically binds AGPs and can be used for histochemical staining, isolating and probing the function of AGPs. Here, the role of AGPs in tomato (Lycopersicon esculentum Mill. cv. UC82B) seed germin...
متن کاملCell wall development in maize coleoptiles.
The physical bases for enhancement of growth rates induced by auxin involve changes in cell wall structure. Changes in the chemical composition of the primary walls during maize (Zea mays L. cv WF9 x Bear 38) coleoptile development were examined to provide a framework to study the nature of auxin action. This report documents that the primary walls of maize cells vary markedly depending on deve...
متن کاملStem xylem resistance to cavitation is related to xylem structure but not to growth and water-use efficiency at the within-population level in Populus nigra L.
Xylem resistance to drought-induced cavitation is a key trait of plant water relations. This study assesses the genetic variation expressed for stem cavitation resistance within a population of a riparian species, the European black poplar (Populus nigra L.), and explores its relationships with xylem anatomy, water-use efficiency (WUE), and growth. Sixteen structural and physiological traits re...
متن کاملMembrane proteins synthesized but not processed by isolated maize chloroplasts
One-dimensional maps of proteolytic fragments generated by digestion with Staphylococcus aureus protease in sodium dodecyl sulfate (SDS) were used to identify three polypeptides synthesized by isolated Zea mays chloroplasts. This technique does not depend upon proper incorporation of the newly synthesized polypeptides into a more complex structure for their identification. The only preliminary ...
