Abstract The productivity of common bean (Phaseolus vulgaris L.), an economically important legume, is severely hindered by drought stress. While melatonin (Mel) and methyl jasmonate (MeJA) are known to alleviate abiotic stresses, their combined effects in mitigating drought-induced oxidative stress are unknown. Here, we examined the synergistic effects of Mel and MeJA in alleviating drought-associated oxidative damage in common bean. Compared with well-watered controls, drought stress caused a significant decline in plant biomass, photosynthetic pigments, and photosystem II efficiency (F_v/F_m). Drought also significantly increased hydrogen peroxide (H₂O₂) accumulation, which likely contributed to membrane lipid peroxidation, as indicated by… More >

Abstract Cytokinins are ancient hormones present across all kingdoms of life except archaea, although functional biosynthesis pathways have yet to be identified in animalia. Known for their roles in cell division and proliferation, cytokinins are critical to plant life, as they regulate various aspects of vegetative growth, stress response, and reproduction. In this review, we summarize literature from 2020 to 2025 pertaining to the cytokinin functions in plant reproduction. While general aspects of cytokinin’s role in plant reproduction have been addressed, we particularly focus on the role of cytokinin in reproductive systems due to recent work More >

Abstract Naturally occurring yellow leaf mutants are an important resource for studying pigment content and biosynthesis, as well as related gene expression. In our ongoing cultivation of Rehmannia chingii H. L. Li, we found an off-type yellow plant. The yellowing started with the new leaves and gradually spread downward until the entire plant exhibited a stable shade of yellow. We studied the differences in the chlorophyll and carotenoid content, carotenoid profile, and transcriptome of this yellow-leaf mutant (P2). Compared to the wild-type R. chingii plant (P1), P2 leaves had significantly lower chlorophyll and carotenoid content. LC-MS/MS analysis revealed More >

Abstract Prolonged lack of rain and high-temperature lead to soil water deficits, inhibiting cereal crop growth in early ontogenesis and reducing grain quality and yield. Rye (Secale cereale L.) is a key grain crop, particularly in regions where wheat cultivation is challenging or unfeasible. To clarify its drought adaptation mechanisms, we analyzed the effects of moderate soil drought on growth, hormonal homeostasis, and the dynamics and distribution of free amino acids and phenolic compounds in rye at early vegetative stages and post-recovery. Drought triggered both general and organ-specific changes in endogenous phytohormones. A nonspecific response involved the… More >

Abstract Rice is a crucial food crop globally. Soil salt stress has adverse effects on the physiology and biochemistry of rice, leading to ionic toxicity and disrupted metabolism. Research aimed at improving salt tolerance and understanding its underlying mechanisms in rice is becoming increasingly important. Phytohormones are crucial in managing rice’s reaction to salt stress by controlling its physiological and biochemical functions. Some phytohormones can improve salt tolerance in rice by affecting gene programming, protein expression, and salt stress signaling, thereby helping rice adapt to salt-stressed environments. This review highlights recent advancements in understanding how various More >

Abstract In order to explore the response mechanism of Passiflora edulis Sims to drought stress, the changes in morphological and physiological traits of Passiflora edulis Sims under different drought conditions were studied. A total of 7 germplasm resources of Passiflora edulis Sims were selected and tested under drought stress by the pot culture method under 4 treatment levels: 75%–80% (Control, CK) of maximum field water capacity, 55%–60% (Light Drought, LD) of maximum field water capacity, i.e., mild drought, 40%–45% (Moderate Drought, MD) of maximum field water capacity, i.e., moderate drought and 30%–35% (Severe Drought, SD) of maximum field water… More >

Abstract One hundred twenty-five endophytic microorganisms were isolated from the roots, stems, and leaves of four prominent rice cultivars growing in temperate regions. Their potential to combat rice blast disease and promote plant growth was investigated. The dual culture tests highlighted the strong antagonistic activity of five fungal (ranging from 89%–70%) and five bacterial (72%–61%) endophytes. Subsequent examination focused on volatile compounds produced by selected isolates to counter the blast pathogen. Among these, the highest chitinase (13.76 µg mL⁻¹) and siderophore (56.64%), was exhibited by Aspergillus flavus, and the highest HCN production was shown by Stenotrophomonas maltophilia (36.15 µM… More >

Abstract Plant regeneration is a self-repair of the plant body in response to adverse conditions or damaged structures, and root regeneration allows the plant body to better adapt to its environment by supplementing the roots’ structure. Previous research has shown that adventitious roots can be made to occur from scratch in two ways. Studies that simulate adventitious root regeneration through natural conditions allow the regeneration process to be broadly divided into three stages: the perception of early signals, the massive accumulation of auxin, and the transformation of cell fate. The strength of regeneration, in turn, is More >

Abstract The presence of selenium (Se) is not widely established as crucial for crops, although it is commonly recognized as an important nutrient for animals as well as humans. Even so, it is inevitably accepted that Se usually contributes positively to the life cycle of plants. Previous findings suggested that small amounts of Se seem to have a productive role in growth and production. As a result, Se is assumed to function in multiple ways, primarily by influencing a variety of biochemical and physiological functions. Also, Se also acts as a plant antioxidant and pro-oxidant and… More >

Abstract Indoleacetic acid (IAA) is an important regulator that plays a crucial role in plant growth and responses to abiotic stresses. In the present study, a sand cultivation experiment was carried out to investigate the effects of IAA at different concentrations (0, 0.01, 0.1, 0.5, 1, and 2.5 mmol/L) on maize growth, root morphology, mineral elements (Ca, Mg) and Cd uptake under 20 mg/kg Cd stress. The results showed that 0.01 mmol/L is the optimal IAA concentration for enhancing the Cd tolerance of maize. Compared with the control treatment, 0.01 mmol/L IAA promoted maize growth, with… More >
