Post-translational control of tetrapyrrole biosynthesis in plants, algae, and cyanobacteria.

abstract：:Research into the molecular basis of plant-insect interactions is hampered by the inability to alter the expression of individual genes in plants growing under natural conditions. The ability of virus-induced gene silencing (VIGS) to silence the expression of two jasmonate-induced genes known to mediate the expression...

abstract：:Ammonium is a major inorganic nitrogen source for plants. At low external supplies, ammonium promotes plant growth, while at high external supplies it causes toxicity. Ammonium triggers rapid changes in cytosolic pH, in gene expression, and in post-translational modifications of proteins, leading to apoplastic acidifi...
