Lignin is a phenolic heteropolymer found in most terrestrial plants that contributes an essential role plant growth, abiotic stress tolerance, and biotic resistance. Recent research grass lignin biosynthesis has differences compared to dicots such as Arabidopsis thaliana . For example, the prolific incorporation of hydroxycinnamic acids into secondary cell walls improve structural integrity vascular elements via covalent crosslinking. Conversely, fundamental monolignol chemistry conserves mechanisms translocation polymerization across phylum. Emerging evidence suggests compositions contribute periods often alter cereal hinder pathogenesis. This same recalcitrance also inhibits industrial valorization biomass, making alterations reductions field research. review presents update biosynthesis, translocation, polymerization, highlights how lignified development responses, briefly addresses genetic engineering strategies may benefit applications.

WRKY Transcription Factors (TFs) as Key Regulators of Plant Resilience to Environmental Stresses: Current Perspective

Agronomy, Journal Year: 2024, Volume and Issue: 14(10), P. 2421 - 2421

Published: Oct. 19, 2024

Plants encounter various stresses in their natural environments and can effectively respond to only one stress at a time. Through complex gene network, transcription factors (TFs) such as WRKY TFs regulate diverse array of responses. The clarification the structural characteristics proteins, along with recent advancements molecular dynamics simulations, has shed light on formation, stability, interactions DNA–protein complexes. This provided novel viewpoint regarding control TFs. investigation superfamilies, encompassing historical development, diversity, evolutionary patterns, become feasible due transcriptome approach’s capacity provide extensive comprehensive transcripts. significance lies pivotal role within several signaling cascades regulatory networks that influence plant defense present review summarizes functional aspects high-volume sequence data from different species studied date.

Published: July 29, 2024

Drought stress poses a significant risk to soybean production, as it relies on optimum rainfall under rainfed conditions. Exposure brief dry periods during early vegetative growth impacts and development. Choosing genotype that can withstand with minimal impact physiology might help sustain biomass or yields low Therefore, this study characterized 64 genotypes for traits associated drought tolerance the stage two soil moisture treatments, 100% evapotranspiration (well-watered) 50% (drought), using Soil-Plant-Atmosphere Research (SPAR) units. Eighteen morpho-physiological responses were assessed, their relationship was investigated. significantly increased root weight, volume, root-to-shoot ratio but reduced shoot weight. Drought-stressed plants canopy temperature by 3.1 °C. Shoot weight positively correlated surface area (r = 0.52, P < 0.001) 0.65, 0.001). There strong negative correlation between (P 0.01). Further, combined response index strongly weakly physiological index. These findings suggest (S55-Q3 R2C4775) high above-ground balanced improves vegetative. could serve valuable genetic resources dissect molecular networks underlying ultimately be used in breeding programs improve ability at stage.

Role of Carrot (Daucus carota L.) Storage Roots in Drought Stress Adaptation: Hormonal Regulation and Metabolite Accumulation

Metabolites, Journal Year: 2025, Volume and Issue: 15(1), P. 56 - 56

Published: Jan. 16, 2025

Background: Drought stress has become one of the biggest concerns in threating growth and yield carrots (Daucus carota L.). Recent studies have shed light on physiological molecular metabolisms response to drought carrot plant; however, tissue-specific responses regulations are still not fully understood. Methods: To answer this curiosity, study investigated interplay among tissues, such as leaves (L); storage roots (SRs); lateral (LRs) under conditions. This revealed that SRs played a crucial role an early perception by upregulating key genes, including DcNCED3 (ABA biosynthesis) DcYUCCA6 (auxin biosynthesis). The abundance osmolytes (proline; GABA) carbohydrates (sucrose; glucose; fructose; mannitol; inositol) was also significantly increased each tissue. In particular, LRs accumulated high levels these metabolites promoted Conclusions: Our findings suggest SR acts central regulator synthesizing ABA auxin, which modulate accumulation LRs. provides new insights into mechanisms tolerance, emphasizing plays improving resistance.

Gross primary productivity is more sensitive to accelerated flash droughts

Communications Earth & Environment, Journal Year: 2025, Volume and Issue: 6(1)

Published: Jan. 17, 2025

Flash droughts, characterized by their rapid onset, substantially affect terrestrial ecosystems. However, the sensitivity of ecosystem productivity to development flash droughts under varying vegetation conditions remains poorly understood. Here we investigate response speed drought onset for different plant functional types, considering decline rate root-zone soil moisture and standardized gross primary anomaly. Our findings reveal a significant increase approximately 10% in proportion 1- 2-pentad (5 10 days) leading negative anomalies during 2001–2018. Furthermore, while at higher rates, they do not promptly respond on shorter timescale faster-onset compared slower-onset droughts. Vegetation types with shallower root systems exhibit sensitivities suggesting an escalating threat ecosystems changing climate. Fast-onset have become more frequent between 2001 2018, faster is associated larger impacts productivity, suggests analysis observation-based data.

Maize is a major crop of the Eastern Himalayan Region (EHR) which faces significant environmental challenges including waterlogging (WL) under changing climate. Through microcosm and field experiments, this study aimed to evaluate phenotypic plasticity adaptive mechanisms maize landraces WL conditions at seedling flowering stages. Based on response coefficient tolerance 14 stage were found be tolerant whereas RCM-12-19, RCM-32-19, RCM-16-19, emerged as both At stage, Root Length ratio (RLR) has increased stress tune 98.4 % while Mass Ratio (RMR) ranged from 0.09 0.47 for control 0.10 0.55 WL. Root:shoot varied 0.88 0.11-1.23 WL, respectively total 19 genotypes reflected trait Phenotyping key root traits (brace angle (BA1), branching, crown number) revealed their substantial contribution resilience, confirmed by principal component analysis (PCA) regression models. PCA indicates, tissue density (RTD) fineness (RF) like RCM-34-19, RCM-10-19, RCM-23-19, RCM-42-19, RCM-31-19 are closely associated with second (PC2). Whereas, RCM-39-19, RCM-52-19, RCM-2-19, RCM-43-19, RCM-5-19, RCM-45-19, RCM-47-19, RCM-50-19 exhibited strong positive loadings (PC2) BA1. The results indicate that brace- roots exhibit genotype-dependent architectural plasticity, reduces metabolic cost soil exploration increasing BA1, branching brace (BB), number (BO) decreasing above-ground whorls (BW); thereby improving nutrient uptake topsoil stress. RCM-23-19 demonstrated rapid growth after supporting potential breeding WL-tolerant maize. These findings align "steep, cheap, deep" (SCD) ideotype, where reduced deeper architecture improve yield. Genotype RCM-11-19 apart scoring high through visual was also have highest dry biomass (76.7 g plant-1) grain yield (12.2 conditions.
