WHAT TELL US THE BIONUMBERS FOR PROTEIN PHOSPHORYLATION IN PLANT DEFENSES

Abstract

Plants to survive against to devastating impact of invasive biotic agents have to powerfully struggle in armed combat with microorganisms. Therefore they need to activate rapidly and efficiently pre-existing potential defensive chemicals. As soon as perception initial external stimuli through plant cell membrane receptors and/or cytoplasmic resistance proteins before activity of related genes, some proteins participated in plant immunity undergo alterations referred as molecular modification. Phosphorylation is one of the first steps and most important modifications in signal transduction pathways of plant immunty. While transcription/translation of the gene dependening to molecular size, organism type, ribosome number is proceed in time unit from seconds to minutes, whereas phosphorylation is occurred in the time period expressed with milliseconds/seconds. Why does protein phosphorylation in plant cells occur quickly in comparison to gene expression? In this commentary work inquired of this question, speedity of gene expression and phosphorylation processes on time profile is compared outlining with bionumbers
