“…In addition, we identified RNA demethylase gene ALKBH10B as one of the hub genes in the module highly related to ion balance. It is well known that the dynamic co-regulation of methylation and demethylation is a major process in regulating RNA transcription, and the demethylation was controlled by demethylase ( Shi et al., 2022 ). ALKBH encodes a m6A demethylase, and some members belonging to ALKBH demethylase family were documented to be triggered by salt stress, such as ALKBH9A in Arabidopsis ( Růžička et al., 2017 ).…”

IntroductionAlfalfa, a globally cultivated forage crop, faces significant challenges due to its vulnerability to salt stress. Jasmonates (JAs) play a pivotal role in modulating both plant growth and response to stressors.MethodsIn this study, alfalfa plants were subjected to 150 mM NaCl with or without methyl jasmonate (MeJA). The physiological parameters were detected and a transcriptomic analysis was performed to elucidate the mechanisms underlying MeJA-mediated salt tolerance in alfalfa.ResultsResults showed that exogenous MeJA regulated alfalfa seed germination and primary root growth in a dose-dependent manner, with 5µM MeJA exerting the most efficient in enhancing salt tolerance. MeJA at this concentration elavated the salt tolerance of young alfalfa seedlings by refining plant growth, enhancing antioxidant capacity and ameliorating Na+ overaccumulation. Subsequent transcriptomic analysis identified genes differentially regulated by MeJA+NaCl treatment and NaCl alone. PageMan analysis revealed several significantly enriched categories altered by MeJA+NaCl treatment, compared with NaCl treatment alone, including genes involved in secondary metabolism, glutathione-based redox regulation, cell cycle, transcription factors (TFs), and other signal transductions (such as calcium and ROS). Further weighted gene co-expression network analysis (WGCNA) uncovered that turquoise and yellow gene modules were tightly linked to antioxidant enzymes activity and ion content, respectively. Pyruvate decar-boxylase (PDC) and RNA demethylase (ALKBH10B) were identified as the most central hub genes in these two modules. Also, some TFs-hub genes were identified by WGCNA in these two modules highly positive-related to antioxidant enzymes activity and ion content.DiscussionMeJA triggered a large-scale transcriptomic remodeling, which might be mediated by transcriptional regulation through TFs or post-transcriptional regulation through demethylation. Our findings contributed new perspectives for understanding the underneath mechanisms by which JA-mediated salt tolerance in alfalfa.

“…Flowering time control integrates external environmental factors (daylength, temperature, light, stress, and nutritional status) and endogenous signals from the plant itself ( Kobayashi and Weigel, 2007 ; Ahmad et al., 2022 ; Khosa, 2022 ). The mechanisms by which several environmental factors (daylength, temperature, and stress) alter flowering time have been well characterized and reviewed ( Cho et al., 2017 ; Fernández-Calleja et al., 2021 ; Freytes et al., 2021 ; Lin et al., 2021 ; Luo et al., 2021 ; Osnato et al., 2022 ; Preston and Fjellheim, 2022 ; Shi et al., 2022 ); however, there are fewer reports on how nutrients affect flowering time. In this review, we summarize what is known about the interactions between nutrients [primarily nitrogen (N), phosphorus (P), and potassium (K)] and flowering time.…”

Nutrient-mediated modulation of flowering time

Nutrition affects plant growth and development, including flowering. Flowering represents the transition from the vegetative period to the reproduction period and requires the consumption of nutrients. Moreover, nutrients (e.g., nitrate) act as signals that affect flowering. Regulation of flowering time is therefore intimately associated with both nutrient-use efficiency and crop yield. Here, we review current knowledge of the relationships between nutrients (primarily nitrogen, phosphorus, and potassium) and flowering, with the goal of deepening our understanding of how plant nutrition affects flowering.

“…Flowering is a crucial developmental transition that results from coordinated interactions of a large number of factors. These factors integrate internal signals and external stimuli, and it is a period highly sensitive to stress [ 6 ]. Plants’ response to stressors may vary depending on the species and severity of the stress, but in general, flowering time can either be accelerated or delayed [ 7 ].…”

“…It is a prominent stress response phytohormone critical for both biotic and abiotic stress responses. Salicylic acid regulates the transition to flowering by regulating key floral genes, including FLOWERING LOCUS C , CONSTANS , and SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 , and FLOWERING LOCUS T [ 6 , 8 , 9 , 10 ]. Salicylic acid is also required for the activation of systemic acquired resistance, which has a common regulatory mechanism with flowering activation [ 11 ].…”

The reproductive stage of plant development has the most critical impact on yield. Flowering is highly sensitive to abiotic stress, and increasing temperatures and drought harm crop yields. Salicylic acid is a phytohormone that regulates flowering and promotes stress resilience in plants. However, the exact molecular mechanisms and the level of protection are far from understood and seem to be species-specific. Here, the effect of salicylic acid was tested in a field experiment with Pisum sativum exposed to heat stress. Salicylic acid was administered at two different stages of flowering, and its effect on the yield and composition of the harvested seeds was followed. Plants treated with salicylic acid produced larger seed pods, and a significant increase in dry weight was found for the plants with a delayed application of salicylic acid. The analyses of the seed proteome, lipidome, and metabolome did not show any negative impact of salicylic treatment on seed composition. Identified processes that could be responsible for the observed improvement in seed yields included an increase in polyamine biosynthesis, accumulation of storage lipids and lysophosphatidylcholines, a higher abundance of components of chromatin regulation, calmodulin-like protein, and threonine synthase, and indicated a decrease in sensitivity to abscisic acid signaling.
