“…In addition, it is a crucial signalling molecule in the plant's reaction to pathogen attack, helping the plant to resist local and systemic diseases. [23] Exogenous SA administration enhances enzymatic and non-enzymatic antioxidant activity, upregulates photosynthesis, and aids in seed germination, growth, and flowering [24]. Many studies have demonstrated that SA reduces DNA damage and regulates antioxidants to reduce oxidative stress, thus promoting plant growth and development in challenging environments [25].…”

To achieve the optimal and best growth of the plant and its production under salt stress, some materials were added in specific and sufficient quantities to obtain an ideal crop of salt-sensitive chili pepper plants. This experiment was carried out during the period (November 2022 to June 2023) in the Botanical Garden of the College of Science for women / University of Baghdad to study the effect of the amino acid polyamine and the growth regulator salicylic acid and their interactions on 7 traits under salt stress. Reflecting the total of quantitative and yield traits of Chili pepper (salt sensitive) Capsicum annuum L. Var. Anaheim TMR23 (from Biostim protection, Bakker Brothers, China). The experiment included three factors with three replications. The first factor included three levels (P0, P1, P2) (0, 2, 3 mg.l-1 polyamine), the second factor includes three levels (A0, A1, A2) (0, 75, 150 mg.l-1 salicylic acid) Likewise, the third factor included three levels of sodium chloride (S0, S1, S2) (0, 2000, 4000 PPM). The results of the experiment showed that different levels of salinity had a negative effect on the quantitative characteristics of chilli pepper plants, and it was noted that the second concentration of polyamine P2 and salicylic acid A2 were superior in reducing salinity. All values in many of the properties studied when interacting between polyamines and salicylic acid, it was observed that the highest value was P2A2 for the same properties studied when compared to the control, except for proline. While the ternary interaction P2A2S0 gave the highest value compared to the rest of the studied traits. It is clear from the results that proline had the highest value for all characteristics, In conclusion, this result indicates that the addition of polyamines and salicylic acid and their interactions effectively reduce the harmful effect of salt stress in chili pepper.

“…Salicylic acid is well known for plant defense against pathogens; however, it also regulates plant developmental processes. Although some studies suggest SA as a negative regulator of seed size ( Leclere et al., 2008 ), it is reported not to have a pronounced role in the regulation of seed size/weight under normal growing conditions ( Ali and Inas Abdulsattar, 2019 ; Çetinbaş-Genç and Vardar, 2021 ; Hu et al., 2022 ). A previous study has also indicated that SA inhibits seed germination in barley ( Xie et al., 2007 ), reflecting its role as a positive regulator of seed dormancy.…”

Plant hormones play important roles in seed development; however, transcriptional regulation of their metabolism and levels of the respective bioactive forms during barley seed development is poorly understood. To this end, this study performed a comprehensive analysis of changes in the expression patterns phytohormone metabolism genes and levels of the respective bioactive forms in the embryo and endosperm tissues. Our study showed the presence of elevated levels of abscisic acid (ABA), bioactive forms of gibberellins (GAs), jasmonate (JA) and cytokinins (CKs), auxin and salicylic acid (SA) in the endosperm and embryo tissues at early stage of seed filling (SF). The levels of all hormones in both tissues, except that of ABA, decreased to low levels during SF. In contrast, embryonic ABA level increased during SF and peaked at physiological maturity (PM) while the endospermic ABA was maintained at a similar level observed during SF. Although its level decreased high amount of ABA was still present in the embryo during post-PM. We detected low levels of ABA in the endosperm and all the other hormones in both tissues during post-PM phase except the relatively higher levels of jasmonoyl-isoleucine and SA detected at late stage of post-PM. Our data also showed that spatiotemporal changes in the levels of plant hormones during barley seed development are mediated by the expression of specific genes involved in their respective metabolic pathways. These results indicate that seed development in barley is mediated by spatiotemporal modulation in the metabolism and levels of plant hormones.

bHLH010/089 Transcription Factors Control Pollen Wall Development via Specific Transcriptional and Metabolic Networks in Arabidopsis thaliana

The pollen wall is a specialized extracellular cell wall that protects male gametophytes from various environmental stresses and facilitates pollination. Here, we reported that bHLH010 and bHLH089 together are required for the development of the pollen wall by regulating their specific downstream transcriptional and metabolic networks. Both the exine and intine structures of bhlh010 bhlh089 pollen grains were severely defective. Further untargeted metabolomic and transcriptomic analyses revealed that the accumulation of pollen wall morphogenesis-related metabolites, including polysaccharides, glyceryl derivatives, and flavonols, were significantly changed, and the expression of such metabolic enzyme-encoding genes and transporter-encoding genes related to pollen wall morphogenesis was downregulated in bhlh010 bhlh089 mutants. Among these downstream target genes, CSLB03 is a novel target with no biological function being reported yet. We found that bHLH010 interacted with the two E-box sequences at the promoter of CSLB03 and directly activated the expression of CSLB03. The cslb03 mutant alleles showed bhlh010 bhlh089–like pollen developmental defects, with most of the pollen grains exhibiting defective pollen wall structures.
