Abstract Sugar signaling is one of the most critical regulatory signals in plants, and its metabolic network contains multiple factors. signal molecules regulate cellular activities organism development by combining with other intrinsic factors environmental inputs. HXK, SnRK1, TOR are three fundamental proteins that have a pivotal role metabolism sugars plants. being initial glucose sensor discovered renowned for multifaceted characteristics. Recent investigations unveiled HXK additionally assumes significant plant hormonal abiotic stress. SnRK1 serves as vital regulator growth under energy-depleted circumstances, whereas TOR, large protein, acts central integrator pathways govern cell metabolism, organ development, transcriptome reprogramming response to diverse stimuli. Together, these two work sense upstream modulate downstream proliferation. In recent years, there has been an increasing amount research on proteins, particularly SnRK1. Furthermore, studies found not only sugar but also exhibit certain crosstalk regulating development. This review provides comprehensive overview summary basic functions networks proteins. It aims serve reference further exploration interactions between their involvement co-regulatory networks.

HEXOKINASE1 and glucose-6-phosphate fuel plant growth and development

Development, Год журнала: 2023, Номер 150(20)

Опубликована: Окт. 15, 2023

ABSTRACT As photoautotrophic organisms, plants produce an incredible spectrum of pigments, anti-herbivory compounds, structural materials and energic intermediates. These biosynthetic routes help grow, reproduce mitigate stress. HEXOKINASE1 (HXK1), a metabolic enzyme glucose sensor, catalyzes the phosphorylation hexoses, key introductory step for many these pathways. However, previous studies have largely focused on sensing signaling functions HXK1, importance enzyme's catalytic function is only recently being connected to plant development. In this brief Spotlight, we describe developmental significance HXK1 its role in pathways, specifically glucose-6-phosphate production. Furthermore, emerging connections between metabolism development suggest that activity regulate discrete areas

HXK, SnRK1, and TOR signaling in plants: Unraveling mechanisms of stress response and secondary metabolism

Science Progress, Год журнала: 2024, Номер 107(4)

Опубликована: Окт. 1, 2024

As sessile photoautotrophs, plants constantly encounter diverse environmental stresses. Recent research has focused on elucidating sugar and energy signaling mediated by hexokinase (HXK), sucrose non-fermenting 1-related protein kinase 1 (SnRK1), the target of rapamycin (TOR) assessing its intricate interplay with hormones secondary metabolism. HXK serves as a pivotal regulator glucose sensing It affects plant growth development in response to nutrient availability. SnRK1 acts vital sensor that regulates metabolic adjustments during stress bolster resilience. Moreover, TOR integrates signals finely modulate development, balancing cellular metabolism resource allocation. Understanding functions HXK, SnRK1, can provide profound insights into adaptation mechanisms open promising avenues for leveraging biotechnological strategies enhance tolerance nutritional value crops. This narrative review focuses recent advancements molecular explores their potential applications agricultural biotechnology.

Complex Role of Photoreceptors in Light and Temperature Sensing: From Mechanism to the Target Genes Regulation. A Focus on the Genes Related to the Biosynthesis of Phenolic Compounds

Опубликована: Янв. 31, 2024

Due to the ongoing climate change plants face multiple stress factors (mainly abiotic ones) simultaneously, which means that reduced yields of critical crops (including wheat, rice, or barley) can be expected. Therefore, our understanding light and temperature sensing mechanisms related signaling is primary importance. Herein we present a review focused on direct (ensured via photoreceptors) light, main factor driving development, phenology, especially resistance against oxidative increased accumulation protective metabolites crops. Thus, in following text, special attention paid description plant photoreceptors, their mode action, ranges perception, pathways leading activation target transcription factors. These finally lead alterations expression genes photoprotection. focus research, production phenolic compounds (PheCs) were selected as representative group having UV-screening, antioxidative function meaning activity resulting proteins significantly contribute tolerance cues.

Phenolic compounds are a group of secondary metabolites responsible for several processes in plants-these involved plant-environment interactions (attraction pollinators, repelling herbivores, or chemotaxis microbiota soil), but also have antioxidative properties and capable binding heavy metals screening ultraviolet radiation. Therefore, the accumulation these has to be precisely driven, which is ensured on levels, most important aspect seems control gene expression. Such transcriptional requires presence activity transcription factors (TFs) that driven based current requirements plant. Two environmental mainly affect phenolic compounds-light temperature. Because it known light perception occurs via specialized sensors (photoreceptors) we decided combine biophysical knowledge about plants with molecular biology-based specific genes bridge gap between them. Our review offers insights into regulation related compound production, strengthens understanding plant responses cues, opens avenues manipulation total content profile potential applications horticulture food production.
