متن کاملEthylene and 1-Aminocyclopropane-1-carboxylate (ACC) in Plant–Bacterial Interactions
Ethylene and its precursor 1-aminocyclopropane-1-carboxylate (ACC) actively participate in plant developmental, defense and symbiotic programs. In this sense, ethylene and ACC play a central role in the regulation of bacterial colonization (rhizospheric, endophytic, and phyllospheric) by the modulation of plant immune responses and symbiotic programs, as well as by modulating several developmen...
متن کاملDifferential expression and internal feedback regulation of 1-aminocyclopropane-1-carboxylate synthase, 1-aminocyclopropane-1-carboxylate oxidase, and ethylene receptor genes in tomato fruit during development and ripening.
We investigated the feedback regulation of ethylene biosynthesis in tomato (Lycopersicon esculentum) fruit with respect to the transition from system 1 to system 2 ethylene production. The abundance of LE-ACS2, LE-ACS4, and NR mRNAs increased in the ripening fruit concomitant with a burst in ethylene production. These increases in mRNAs with ripening were prevented to a large extent by treatmen...
متن کاملCharacterization of 1-aminocyclopropane-1-carboxylate (ACC) oxidase in broccoli florets and from Escherichia coli cells transformed with cDNA of broccoli ACC oxidase
During senescence of broccoli (Brassica oleracea L. var. italica) florets (flower buds), the rate of ethylene production increased, almost paralleling the rapid increase in 1-aminocyclopropane-1-carboxylate (ACC) oxidase activity. The increase in ACC oxidase activity was strongly suppressed by the administration of cycloheximide, suggesting that it may have resulted from the de novo synthesis o...
متن کاملGlutathione Regulates 1-Aminocyclopropane-1-Carboxylate Synthase Transcription via WRKY33 and 1-Aminocyclopropane-1-Carboxylate Oxidase by Modulating Messenger RNA Stability to Induce Ethylene Synthesis during Stress.
Glutathione (GSH) plays a fundamental role in plant defense-signaling network. Recently, we have established the involvement of GSH with ethylene (ET) to combat environmental stress. However, the mechanism of GSH-ET interplay still remains unexplored. Here, we demonstrate that GSH induces ET biosynthesis by modulating the transcriptional and posttranscriptional regulations of its key enzymes, 1...
