Chickpea ( Cicer arietinum L. ) is a major pulse crop; however, its protein quality is limited due to low levels of sulfur-containing amino acids. Sulfur deficiency in agricultural soils necessitates improved sulfate uptake and assimilation efficiency. Despite advances in understanding plant sulfate transporters (SULTRs), their molecular complexity and functional roles in legumes remain poorly un…

Abstract Background Intraspecific hybridization in allopolyploid plants can generate additive and nonadditive changes in gene expression through interactions between divergent parental genomes. However, how it simultaneously affects gene expression and the relative expression of homoeologs in higher-order polyploids is less well understood. To study this, we sequenced seedling leaf transcriptomes…

Stay-green (SGR) genes encode Mg‑dechelatase and play critical roles in chlorophyll degradation. Increasing evidence suggests that SGR genes also participate in abiotic stress responses, including drought and salinity tolerance, in various plant species. However, systematic identification and functional analysis of the SGR gene family in cotton ( Gossypium hirsutum ) remain limited. In this study…

Abstract Background This study aimed to synthesize melatonin laoded chitosan nanoparticles (MEL NPs) and assess its effects on the production of bioactive metabolites, antioxidant activity and gene expression in O. basilicum culture. Results Our results showed that the total phenolic (TPC) and total flavonoid (TFC) content of basil leaves treated with melatonin (MEL) and MEL NPs at 5, 10, and 20 …

Nitrogen (N) deficiency severely constrains global crop productivity, yet acclimation strategies in cereals remain incompletely understood. Hydroponically grown barley ( Hordeum vulgare ) plants were subjected to N starvation for 14 days. Photosynthetic properties were monitored across leaf ages and starvation durations to dissect acclimation adjustments. Growth was markedly inhibited, with shoot…

Abstract Rubberwood derived from plantation replanting of Hevea brasiliensis Müll. Arg. is an increasingly important renewable resource for timber, furniture, and biomass-based industries in Southeast Asia. Despite its growing industrial value, the genetic architecture underlying rubberwood quality remains largely unresolved, limiting the use of molecular breeding for simultaneous improvement of …

Abstract Background Limonium sinense is a recretohalophyte with both ecological and economic value inhabiting China’s coastal saline-alkali zones, and it can play an important role in saline-alkali soil amelioration and coastal vegetation restoration. Impacted by coastal development and habitat fragmentation, the size of its wild populations has declined sharply in recent years; thus, elucidating…
