Published: Dec. 16, 2020

Abstract Phenylpropanoid metabolism is one of the most important metabolisms in plants, yielding more than 8,000 metabolites contributing to plant development and plant–environment interplay. materialized during evolution early freshwater algae that were initiating terrestrialization land plants have evolved multiple branches this pathway, which give rise including lignin, flavonoids, lignans, phenylpropanoid esters, hydroxycinnamic acid amides, sporopollenin. Recent studies revealed many factors participate regulation metabolism, modulate homeostasis when undergo successive developmental processes are subjected stressful environments. In review, we summarize recent progress on elucidating contribution coordination interaction, metabolic flux redirection among diverse routes. addition, our review focuses at transcriptional, post‐transcriptional, post‐translational, epigenetic levels, response phytohormones biotic abiotic stresses.

The bZIP transcription factor MdHY5 regulates anthocyanin accumulation and nitrate assimilation in apple

Horticulture Research, Journal Year: 2017, Volume and Issue: 4(1)

Published: June 7, 2017

The basic leucine zipper (bZIP) transcription factor HY5 plays a multifaceted role in plant growth and development. Here the apple MdHY5 gene was cloned based on its homology with Arabidopsis HY5. Expression analysis demonstrated that induced by light abscisic acid treatments. Electrophoretic mobility shift assays transient expression subsequently showed positively regulated both own of MdMYB10 binding to E-box G-box motifs, respectively. Furthermore, we obtained transgenic calli overexpressed gene, coloration promoted anthocyanin accumulation regulating downstream biosynthesis genes. In addition, transcript levels series nitrate reductase genes uptake wild-type were detected. association increased activities contents, results indicated might be an important regulator nutrient assimilation. Taken together, these indicate vital assimilation apple.

Repressors of anthocyanin biosynthesis

New Phytologist, Journal Year: 2021, Volume and Issue: 231(3), P. 933 - 949

Published: April 17, 2021

Anthocyanins play a variety of adaptive roles in both vegetative tissues and reproductive organs plants. The broad functionality these compounds requires sophisticated regulation the anthocyanin biosynthesis pathway to allow proper localization, timing, optimal intensity pigment deposition. While it is well-established that committed steps are activated by highly conserved MYB-bHLH-WDR (MBW) protein complex virtually all flowering plants, repression seems be achieved wide small RNA families function different tissue types response developmental, environmental, hormonal cues. In this review, we survey recent progress identification repressors characterization their molecular mechanisms. We find seemingly very modules act through remarkably similar logic, so-called 'double-negative logic'. Much double-negative production involves signal-induced degradation or sequestration from MBW complex. discuss functional evolutionary advantages logic design compared with simple sequential positive regulation. These provide plausible explanation as why plants have evolved so many repressors.

Far-Red Light Detection in the Shoot Regulates Lateral Root Development through the HY5 Transcription Factor

The Plant Cell, Journal Year: 2018, Volume and Issue: 30(1), P. 101 - 116

Published: Jan. 1, 2018

Plants in dense vegetation compete for resources and detect competitors through reflection of far-red (FR) light from surrounding plants. This causes a reduced red (R):FR ratio, which is sensed phytochromes. Low R:FR induces shade avoidance responses the shoot also changes root system architecture, although this has received little attention so far. Here, we investigate molecular mechanisms detection regulates development Arabidopsis thaliana We do using combination microscopy, gene expression, mutant study approaches setup that allows imaging without exposing roots to treatment. show low perception decreases lateral (LR) density by inhibiting LR emergence. decrease emergence upon FR enrichment regulated phytochrome-dependent accumulation transcription factor ELONGATED HYPOCOTYL5 (HY5) primordia.

Exposure to ultraviolet B (UV-B) light regulates numerous aspects of plant metabolism, morphology and physiology through the differential expression hundreds genes. Photomorphogenic responses UV-B are mediated by photoreceptor UV RESISTANCE LOCUS8 (UVR8). Considerable progress has been made in understanding UVR8 action: structural basis function, how interaction with CONSTITUTIVELY PHOTOMORPHOGENIC 1 initiates signaling REPRESSOR OF PHOTOMORPHOGENESIS proteins negatively regulate action. In addition, recent research shows that mediates several other pathways, particular auxin signaling. Nevertheless, many action remain poorly understood.
