SlWRKY51 regulates proline content to enhance chilling tolerance in tomato

Plant Cell & Environment, Journal Year: 2024, Volume and Issue: 47(12), P. 5104 - 5114

Published: Aug. 15, 2024

Chilling stress is a major environmental factor that significantly reduces crop production. To adapt to chilling stress, plants activate series of cellular responses and accumulate an array metabolites, particularly proline. Here, we report the transcription SlWRKY51 increases proline contents in tomato (Solanum lycopersicum) under stress. expression induced Knockdown or knockout led chilling-sensitive phenotypes, with lower photosynthetic capacity more reactive oxygen species (ROS) accumulation than wild type (WT). The were reduced knockdown lines perhaps explaining phenotypes these lines. D-1-pyrroline-5-carboxylate synthetase (P5CS), which catalyses rate-limiting step biosynthesis, encoded by two closely related P5CS genes (P5CS1 P5CS2). We demonstrate directly activates P5CS1 In addition, VQ (a class plant-specific proteins containing conserved motif FxxhVQxhTG) family member SlVQ10 physically interacts enhance its activation P5CS1. Our study reveals chilling-induced enhances tolerance promoting accumulation.

Exploring the Role of Non-Structural Carbohydrates (NSCs) Under Abiotic Stresses on Woody Plants: A Comprehensive Review

Plants, Journal Year: 2025, Volume and Issue: 14(3), P. 328 - 328

Published: Jan. 22, 2025

Global climate change has increased the severity and frequency of abiotic stresses, posing significant challenges to survival growth woody plants. Non-structural carbohydrates (NSCs), including starch sugars, play a vital role in enabling plants withstand these helping stabilize cellular functions by buffering plant energy demands facilitating recovery on alleviation stress. Despite recognized multiple NSCs, contrasting effects stresses NSCs dynamics remain poorly understood. This review aims explore current knowledge stress conditions drought, salinity, heat, water logging, cold dynamics. The roles regulating stress-resilience responses are also discussed, along with NSC measurement, options for future research directions explored. is based comprehensive literature across different search engines like Scopus, Web Science, Google Scholar (2000–2024) using targeted keywords. study compiles provides insights into adaptive strategies response changing conditions, providing groundwork improve tolerance

Published: Sept. 28, 2024

Climate change has emerged as a crucial global issue that significantly threatens the survival of plants. In particular, low temperature (LT) is one critical environmental factors influence plant morphological, physiological, and biochemical changes during both vegetative reproductive growth stages. LT, including abrupt drops in temperature, well winter conditions, can cause detrimental effects on development tomato plants, ranging from sowing, transplanting, truss appearance, flowering, fertilization, fruit ripening, yields. Therefore, it imperative to understand comprehensive mechanisms underlying adaptation acclimation plants morphological molecular levels. this review, we discuss previous current knowledge changes, which contain parameters involving leaf length (LL), height (PH) stem diameter (SD), set (FS), ripening yield (FY), photosynthetic parameters, cell membrane stability, osmolytes, ROS homeostasis via antioxidants scavenging systems LT stress Moreover, highlight recent advances understanding mechanisms, perception, signaling transduction, gene regulation, epigenetic regulation.

Ethylene is a signalling factor that plays key role in the response of plants to abiotic stresses, such as cold stress. Recent studies have shown exogenous application 1-aminocyclopropane-1-carboxylate (ACC), an ethylene promoter, affects plant tolerance. The cold-responsive specific gene DREB crucial enhancing tolerance by activating several (COR) genes. However, how biosynthesis pathway regulates this thermophilic has yet be fully elucidated.
