Cytokinins (CKs) are a class of phytohormones identified in the early 1960s and mainly responsible for stimulating cell division. Following discovery, research to help understand pluralistic roles CKs plant growth stress biology increased. With their fascinating ability, serve as an important element regulating defense–growth trade-off. Herein, we demonstrate how CK fine-tuning organogenesis different parts horticultural plants is discussed. CK’s role tailoring reproductive (flowering, sex differentiation, fruit set, attributes) has been presented. An extensive explanation CK-mediated response crops abiotic (temperature, drought, salinity) biotic stresses (fungal, bacterial, nematodes) provided. Finally, posit unexplored highlight gaps worth addressing.

Soil toxicity is a major environmental issue that leads to numerous harmful effects on plants and human beings. Every year huge amount of Pb dumped into the environment either from natural sources or anthropogenically. Being heavy metal it highly toxic non-biodegradable but remains in for long time. It considered neurotoxic exerts living In present review article, investigators have emphasized side plants. Further, authors focused various environment. Investigators responses including molecular, biochemical, morphological levels Pb. Further emphasis was given effect elevated microbial population rhizospheres. remediation strategies removal soil water sources.

Auxin biodynamics and its integral role in enhancing plant resilience to environmental cues

Physiologia Plantarum, Год журнала: 2025, Номер 177(2)

Опубликована: Март 1, 2025

Auxins are essential plant hormones that regulate growth, development, and responses to environmental stressors. Plants frequently encounter challenges such as pests, diseases, high temperatures, drought, salinity, which necessitate adaptive mechanisms for survival. modulate stress-responsive signaling pathways by regulating gene expression interacting with other phytohormones, thereby influencing physiological processes maintain homeostasis under stress conditions. This review elucidates the molecular through auxins mediate biotic abiotic stresses. The findings indicate pivotal in activating defense pathways. Differential of auxin-related genes has been observed various crops conditions, underscoring their role enhancing resistance against pathogens improving drought tolerance. Additionally, influence root architecture growth responses, facilitating adaptations trichome development herbivory. Moreover, interplay between auxin phytohormones is crucial effective responses. Overall, play a multifaceted enabling plants cope stresses mechanisms. Understanding these complex involving can inform future research aimed at engineering resilient varieties capable thriving changing climates. Further studies needed clarify specific functions contexts develop practical applications crop improvement.

Pan-genome identification and expression analysis of the auxin response gene family in potato

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 2, 2025

Background The auxin response factor plays an important role in plant growth and development, stress resistance. In this study, the family was identified based on 47 high-quality potato pan-genomes. Results There were no core or private genes among 28 members of pan-gene family, with only one being a near-core gene, while rest non-essential genes. Ka/Ks ratio values showed that gene under positive selection, remaining purifying selection. Structural variations 21 genomes did not significantly affect expression members, nor any significant differences observed. led to changes conserved domains some strains. RNA-seq data analysis response-factor differentially expressed drought relative control conditions; moreover, various differed stress. Further revealed transcription factors involved regulating members. Conclusions Our findings function biological processes potato, provide new theoretical reference for resistance-breeding crop species.

Comparative transcriptomic analysis revealed important processes underlying the static magnetic field effects on Arabidopsis

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Май 28, 2024

Static magnetic field (SMF) plays important roles in various biological processes of many organisms including plants, though the molecular mechanism remains largely unclear. Here this study, we evaluated different setups to test their effects on growth and development Arabidopsis ( thaliana ), discovered that plant was significantly enhanced by inhomogeneous SMF generated a regular triangular prism magnet perpendicular direction gravity. Comparative transcriptomic analysis revealed auxin synthesis signal transduction genes were upregulated exposure. also facilitated plants maintain iron homeostasis. The expression metabolism-related downregulated SMF, however, content tissues relatively unchanged. Furthermore, exposure helped reduce ROS level synergistically oxidant balance activity antioxidant enzymes accumulation nicotinamide. Taken together, our data suggested is involved regulating through maintaining homeostasis balancing oxidative stress, which could be beneficial for survival growth. work presented here would extend understanding regulatory network how affects growth, provide insights into novel synthetic biology technologies engineer stress-resistant high-yielding crops.

Allelochemicals Released from Rice Straw Inhibit Wheat Seed Germination and Seedling Growth

Agronomy, Год журнала: 2024, Номер 14(10), С. 2376 - 2376

Опубликована: Окт. 14, 2024

Recently, returning rice straw to soil has become a common problem in wheat production because it causes decreased seedling emergence. Allelopathy is an important factor affecting seed germination. However, the effects of extracts on germination and growth remain unclear. Wheat seeds seedlings were treated with 30 g L−1 leaf (L1), 60 (L2), stem (S1), (S2) sterile water (CK) study allelopathic growth. The α-amylase antioxidant enzyme activities seeds; agronomic traits, photosynthetic indicators, nutrient contents seedlings; phenolic acids determined. Common allelochemicals, including 4-hydroxybenzoic acid, hydrocinnamic trans-cinnamic vanillic benzoic protocatechualdehyde, caffeic syringic sinapic salicylic detected extracts. Low-concentration (30 L−1) had no effect rate seeds. High-concentration (60 by 11.00% 12.02%. Rice extract activity, gibberellin content but increased superoxide dismutase, peroxidase, catalase malondialdehyde Allelochemicals entered internal tissues seeds, where they activity ultimately leading inhibitory SPAD value indicators seedlings. fresh weight root length 31.37% 45.46%. nitrogen potassium These results indicated that low-concentration high-concentration released allelochemicals inhibited findings provide basis for improvement return techniques.

Roots of Lupinus angustifolius L. and enzyme activities in soil contaminated by toxic elements

Plant Soil and Environment, Год журнала: 2024, Номер 70(9), С. 552 - 561

Опубликована: Авг. 20, 2024

The impact of toxic elements (TEs) contaminating the root zone Lupinus angustifolius L. on enzymatic activities, nitrification rate, and changes in system was evaluated. Lupine cultivated a pot experiment using two types soil – control contamination (with high degree arsenic (As), cadmium (Cd), lead (Pb), zinc (Zn) contamination). After harvesting lupine biomass, enzyme activities (β-glucosidase, acid phosphatase, arylsulphatase, lipase, chitinase, cellobiohydrolase, alanine aminopeptidase, leucine aminopeptidase) soils were analysed. Enzyme decreased with TE contamination. According to our results, arylsulphatase found be most sensitive TEs. rate is closely related plant activity, as it stimulates microbial growth multiplication through exudates. close correlations confirmed this relationship (r = 0.73−0.99). An increasing trend contents roots observed Plant hormones are crucial regulating development under stress conditions. levels determined phytohormones (auxins, abscisic (ABA), salicylic (SA), bioactive cytokinins (bCKs)) lower compared control. Correlations significant negative between content (auxins: r –0.96 –0.97; ABA: –0.83 –0.86; SA: –0.95 –0.99, bCKs: –0.87 –0.93). ratios these (not their absolute values) appear determining factor for protecting plants from oxidative stress.
