Abstract:

This work presents the results of the analysis of the effect of the phytohormone salicylic acid on the secretion of proteins to the apoplast of the pea seedlings roots. It is shown that the secretion of a number of defense proteins (β-1,3-glucanase, acid and alkaline endochitinases, disease resistance response protein, and protease inhibitors) is increased, but there is no activation of the expression of the genes encoding these proteins. A distinctive feature of the pea root response to the salicylic acid was the activation of the expression of the genes encoding isoforms of chitinase-like proteins and the secretion of these proteins into the apoplast.

Cell Signaling in Plants

Cell Signaling in Plants

Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Riboswitches

Riboswitches

Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins. Riboswitches bind directly to a metabolite and can form unique stem-loop or hairpin structures in response to the amount of the metabolite present. They have two distinct regions – a metabolite-binding aptamer and an expression platform.
The aptamer has high specificity for a particular metabolite which allows riboswitches to specifically regulate...
