Many plant secondary metabolites are active and important in the regulation of growth. Certain plant-derived diterpenes known to promote growth, but pathways by which this promotion occurs still unknown. Activity screening revealed that diterpene isopimaric acid exhibits growth-promoting activity rice (

Abstract Plants can experience a variety of environmental stresses that significantly impact their fitness and survival. Additionally, biotic stress harm agriculture, leading to reduced crop yields economic losses worldwide. As result, plants have developed defense strategies combat potential invaders. These involve regulating redox homeostasis. Several studies documented the positive role plant antioxidants, including Ascorbate (Asc), under conditions. Asc is multifaceted antioxidant scavenges ROS, acts as co‐factor for different enzymes, regulates gene expression, facilitates iron transport. However, little attention has been given its transport, regulatory effects, interplay with phytohormones, involvement in processes stress. interacts other components system phytohormones activate various responses reduce growth pathogens promote development Scientific reports indicate contribute resistance against through mutual interactions hormonal systems. This review focuses on enhancing pathogens. Further research necessary gain more comprehensive understanding molecular cellular involved.

Citrus is widely recognized as one of the most economically important fruit crops worldwide. However, citrus growth frequently hindered by external environmental stresses, which severely limit its development and yield. The TGA (TGACG motif-binding factor) transcription factors (TFs) are members bZIP family play essential roles in plant defense responses organ development. Nevertheless, systematic identification functional analysis remains unreported. In this study, genome-wide identified a total seven CsTGA TFs sinensis, were classified into five subgroups. Phylogenetic syntenic revealed that genes highly conserved, with no tandem or segmental duplication events among members. Promoter sequence numerous cis-acting elements associated transcriptional regulation, phytohormone response, adaptation promoters genes. expression patterns under phytohormones three abiotic stresses demonstrated significant multiple various forms adversity. Among all tested treatments, CsTGA7 showed robust response to stresses. Tissue-specific pattern potential biases In-depth localized nucleus possessed activation activity, consistent typical characteristic regulators. summary, our research systematically investigated genomic signature C. sinensis unearthed functions signaling transduction stress responses. Our study establishes basis for further exploration function stress.

High-temperature stress severely limits the growth, development, yield, and quality of garlic (Allium sativum L.), but role hormone signaling in its heat response remains unclear. This study examined changes seven plant hormones expression related genes leaves ('Xusuan No. 6') under (38 °C for 0, 2, 4, 24 h). Growth-promoting hormones, auxin gibberellic acid, significantly decreased within 2 h stress, while stress-response including abscisic jasmonic salicylic ethylene, increased. KEGG pathway analysis revealed significant to biosynthesis signal transduction, such as NCED PYR/PYL ABA pathway, LOX OPR JA biosynthesis, AUX ARF IAA signaling, ERT ERF ethylene signaling. A protein-protein interaction network identified 15 hub potentially coordinating regulation stress. These findings provide a basis functional validation key hormone-related heat-stress suggest potential genetic targets development heat-tolerant varieties.

Silicon (Si) has been proven to enhance the stress resistance of rice, but its effect on lodging rice under dry cultivation (DCR) is still unclear. The purpose this experiment clarify appropriate amount silicon fertilizer for DCR resist and elucidate how it coordinates yield. This used ‘Suigeng 18’ cultivar as material set six fertilizers (SiO2) with dosages 0, 15, 30, 45, 60, 75 kg·ha−1 (Si0, Si1, Si2, Si3, Si4, Si5). Analyze effects key indicators from perspectives plant weight distribution, stem structure composition, root architecture. results showed that Si3 treatment had highest yield lowest index (LI). increases upper three leaves 4–5 internodes, thereby promoting panicle An increase 13.38% in 2/3PWSI (weight 4th–5th stems leaves/weight 1st–3rd lower leaves) can reflect leaf development near panicle. reduces GA/IAA value, shortens length second internode, diameters major minor axes, increasing culm thickness section modulus (SM), achieving “short thick”. also content non-structural carbohydrates (NSCs) lignin cellulose by upregulating expression levels CAD7, PAL, COMT, CesA4 genes, fullness flexural strength (M), “short, thick, strong” reducing LI. 38.95% reduction IFL (second internode length/fullness) reflects positive stem.

ABSTRACT Insecticides play a crucial role as the primary means of controlling agricultural pests, preventing significant damage to crops. However, misuse these insecticides has led development resistance in insect pests against major classes chemicals. The emergence poses serious threat, especially when alternative options for crop protection are limited farmers. Addressing this challenge and developing new, effective, sustainable pest management approaches is not merely essential but also critically important. In absence solutions, understanding root causes behind insects becomes critical necessity. Without understanding, formulation effective combat remains elusive. With playing vital global food security public health, mitigating paramount. Given growing concern over insecticides, review addresses research gap by thoroughly examining causes, mechanisms, potential solutions. examines factors driving resistance, such evolutionary pressure excessive pesticide use, provides detailed analysis including detoxifying enzyme overproduction target site mutations. Providing an it discusses integrated management, strategic insecticide rotation, use new control technologies biological agents. Emphasizing urgency multifaceted approach, concise roadmap guiding future applications.

Abstract Abiotic stresses are the major factors affecting growth and productivity of plants. After perceiving stress, plants orchestrate sophisticated signaling to maximize their fitness under stress conditions which involves synthesis or inhibition various plant regulators (PGRs). Among others, ethylene (ET), polyamines (PAs), nitric oxide (NO) emerging as crucial PGRs that shape responses stresses. Interestingly, biosynthesis is interconnected through common precursors, S-adenosyl methionine (SAM) L-arginine; therefore, generation one affects other. Oxidative driven by production reactive oxygen species (ROS), a feature across all types triggers several downstream such membrane damage osmotic imbalance. The troika ET-PA-NO works in harmony ensure maintenance ROS homeostasis activating enzymatic nonenzymatic antioxidants, phytohormones other PGRs, stress-related proteins. Moreover, this trio also tailors stress-specific closing stomata drought UV-B inducing anaerobic genes during hypoxia, limiting heavy metals uptake modifying Casparian strip, maintaining ion/osmotic integrity salinity cold stress. In present review, efforts have been made interconnections among well crosstalk discrete abiotic unveil understand interrelated regulatory mechanisms.

The adoption of “consortium” potential microorganisms can optimize the forest seedling production process. objective this study was to evaluate in greenhouse conditions effect co-inoculation between Trichoderma harzianum, Bradyrhizobium diazoefficiens, and B. elkanni on growth Schizolobium parahyba var. (Vell.) Blake seedlings. treatments consisted fungi strains (T. harzianum ESALQ 1306); bacteria (B. (SEMIA 5080) + diazoefficiens 587)); consortium (Trichoderma +Bradyrhizobium), a control treatment. seeds were sown, evaluations carried out 120 days after sowing. variables analyzed shoot height (SH), stem diameter (SD), root length (RL), fresh mass (SFM), (RFM), total biomass (TFM), dry (SDM), (BIO), Dickson quality index (DQI). evaluated proved be effective S. parahyba, with emphasis for parameters, promoting an increase SH (23%), SD (36%), RL (84%). For mass, non-inoculated seedlings (control) obtained decrease 67% (TFM) 83% (BIO) compared co-inoculation. results indicate promising method production; biostimulators allowed plant development, which led success morphometric indices. mechanisms involved microorganisms’ native wood species allow their large scale silvicultural sector are still scarce, new research is needed elucidate physiological biochemical involved.
