“…(Groppa and Benavides, 2008;Alcazar et al, 2010). Polyamines are beneficial for protein homeostasis, detoxification of reactive oxygen species (ROS), activation of the antioxidative machinery, and molecular chaperone activity under stress conditions, thereby providing broad-spectrum tolerance against a variety of stresses (Tiburcio et al, 2015;Tyagi et al, 2022). In the current study, a notable increase in polyamines was observed in Barley by promoting the uptake of various inorganic ions.…”

Drought is a severe environmental condition that negatively impacts the metabolic processes of plants, making it one of the most devastating stressors they face. Drought has a significant detrimental impact on grain crops, such as barley. Exogenous application (foliar) of ascorbic acid has been shown to confer tolerance against biotic and abiotic stresses. In the present research, the ability of ascorbic acid to increase drought stress tolerance was investigated in barley (Hordeum vulgare L.). Three barley genotypes, a drought-resistant genotype (V3 = Jau-Haider 93) and two drought-sensitive genotypes (V1 = 92044 and V2 = 92112) were grown in plastic pots under soil conditions. There were two levels of water, control i.e., with adequate irrigation and drought stress with 60% of field capacity. Ascorbic acid was applied as a foliar spray (1 mM). Overall, the plant growth of all genotypes was inhibited by drought stress. However, the drought-tolerant variety (V3 = Jau-Haider 93) showed higher growth rates under drought stress. Ascorbic acid as foliar spray supported the barley plant growth under drought stress to ameliorate the adverse effects of stress by maintaining growth, relative water contents, and osmotic adjustment by enhancing antioxidant enzymes, polyamines, proline and phenolics contents.

“…Polyamines, including putrescine, spermidine, and spermine, boost plant growth and stress tolerance, whether applied externally or produced endogenously in genetically modified plants (Tyagi, et al, 2023). The expression of S-adenosylmethionine decarboxylase 3 ( SAMDC3 ), which converts SAM to decarboxy-S-adenosylmethionine (dcSAM), showed a notable increase in transgenic plants subjected to salinity and drought stress conditions.…”

Understanding the mechanisms behind plant resilience to abiotic stresses is essential for enhancing crop yield and sustainability. This study integrates findings from a comprehensive investigation into the function of the SbPIP2 gene, which encodes an aquaporin protein, in improving the abiotic stress tolerance of transgenic plants. Our integrated approach revealed that transgenic plants overexpressing SbPIP2 significantly reduce reactive oxygen species (ROS) accumulation and exhibit enhanced physiological attributes, including higher seed germination rates, improved growth, early flowering, and better seed setting under stress conditions. Notably, these plants also showed a quicker recovery and completion of their lifecycle post-stress treatment. The transcriptomic analysis provided a deeper understanding of the genetic modifications contributing to stress resilience, highlighting the involvement of genes associated with oxidative stress response, calcium and sugar signaling pathways, stomatal regulation, phytohormone biosynthesis, and flower development. Additionally, the study underscores the central role of abscisic acid (ABA) in mediating stress responses through hormonal regulation, with transgenic plants displaying increased ABA levels due to the upregulation of biosynthesis genes and downregulation of catabolism genes. This hormonal adjustment is critical for stomatal closure, reducing water loss, and enhancing tolerance to abiotic stresses. Our findings elucidate the complex genetic and molecular pathways that underpin abiotic stress tolerance in plants, offering valuable insights for future research aimed at improving crop resilience through genetic engineering, thereby addressing the challenges of climate change and environmental stressors.

“…However, the genomic characters translate the plant's survival capacity to readily adapt to new environments through various amino acids and enzymes, including PAs (Sharma and Dietz 2006, Cattivelli et al 2008, Ramesh et al 2017). PAs particularly not only affect stress adaptation but also play a signi cant role in various aspects of plant growth and development (Gonzalez et al 2021;Tyagi et al 2023). Consequently, the present study focused on the association of different PAs with the growth stages of Alternanthera, as none of the previous studies have investigated such an association.…”

This research delineates the phenological growth stages of Alternanthera species, showcasing variations influenced by seasons and geographic locations. Our study tracked distinct life cycles in A. paronychioides across diverse seasons and in A. sessilis from different locations, revealing intriguing disparities in certain growth stages. Notably, the vegetative and reproductive phases, marked by BBCH code stages 0–1 and 5–9 respectively, exhibited distinct transitions in these species. Germination, leaf development, flowering, fruit development, and senescence stages unveiled stark differences across seasons in pot experiments. However, field experiments showcased uniformity in growth stages, except flowering, irrespective of varied geographical origins, emphasizing the influence of environmental factors, particularly temperature and moisture, over geographic distinctions. Further exploration into the polymorphism of polyamine (PA) metabolism genes uncovered intriguing associations with growth stages. The spermidine synthase (SPDS) gene demonstrated consistent polymorphism, implying its involvement throughout vegetative and reproductive phases. Meanwhile, arginine decarboxylase (ADC) and caffeic acid O-methyltransferase (COMT) genes displayed heightened polymorphism during reproductive stages, possibly indicating stress tolerance during these critical phases. The insights gleaned from this comprehensive analysis not only enhance our understanding of Alternanthera species' growth dynamics but also propose tailored herbicide strategies targeting specific growth stages based on PA metabolism. These findings offer sustainable avenues for weed management while providing valuable contributions to agricultural practices and environmental regulation.
