Wheat Myo-inositol phosphate synthase influences plant growth and stress responses via ethylene mediated signaling.
Sci Rep. 2020 Jul 01; 10(1):10766.SR

Abstract

L-myo-inositol phosphate synthase (MIPS; EC 5.5.1.4) is involved in abiotic stress tolerance, however its disruption and overexpression has also been associated with enhanced tolerance to pathogens. The molecular mechanism underlying the role of MIPS in growth, immunity and abiotic stress tolerance remains uncharacterized. We explore the molecular mechanism of MIPS action during growth and heat stress conditions. We raised and characterized the TaMIPS over-expressing rice transgenics which showed a reduced reproductive potential. Transcriptome analysis of overexpression transgenics revealed the activation of ET/JA dependent immune response. Pull-down analysis revealed the interaction of TaMIPS-B with ethylene related proteins. Our results suggest an essential requirement of MIPS for mediating the ethylene response and regulate the growth. A model is proposed outlining how fine tuning of MIPS regulate growth and stress tolerance of the plant.
