EXPRESSION OF A PLASTID-TARGETED FLAVODOXIN DECREASES CHLOROPLAST REACTIVE OXYGEN SPECIES ACCUMULATION AND DELAYS SENESCENCE IN AGING TOBACCO LEAVES

Expression of a Plastid-Targeted Flavodoxin Decreases Chloroplast Reactive Oxygen Species Accumulation and Delays Senescence in Aging Tobacco Leaves

Leaf senescence is a concerted physiological process involving controlled degradation of cellular structures and reallocation of whole wheat phyllo dough breakdown products to other plant organs.It is accompanied by increased production of reactive oxygen species (ROS) that are proposed to signal cell death, although both the origin and the precise

Multiphysics modeling of thermal behavior, melt pool geometry, and surface topology during laser additive manufacturing

Metal additive manufacturing (AM) processes regularly experience high temperatures, quick velocities and rapid solidification taking place in a small volume melt pool.Accurate capturing of data from the melt pools is very difficult and can require expensive equipment.Physics based numerical models can be used to simulate the AM process.However, the

Insights into the Histone Acetylation-Mediated Regulation of the Transcription Factor Genes That Control the Embryogenic Transition in the Somatic Cells of Arabidopsis

Somatic embryogenesis (SE), which is a process that involves the in vitro-induced embryogenic reprogramming of plant somatic cells, requires dynamic changes in the cell transcriptome.These changes are fine-tuned by many genetic and epigenetic factors, including posttranslational histone modifications such as histone acetylation.Antagonistically act
