The level of endogenous cytokinins changed with growth and development of faba bean (Vicia faba L.) leaves. Typical of juvenile leaves, amounting to 25% of the final leaf size (Smax) was a low content of these plant hormones. The level of cytokinins increased in growing leaves (50% of Smax) and decreased in the leaves that stopped growing. The content of cytokinins in senescent leaves dropped considerably. Exogenous treatment with 6-benzylaminopurine (BAP) had no effect on the structure of terminal phloem; however, it stimulated elongation of mesophyll cells; increases in the area and thickness of leaf blade, amount of photosynthetic pigments, and assimilation potential; and delayed senescence of leaves and defoliation, thereby increasing biomass of the aboveground plant part. It was inferred that BAP had a potential for induction of photosynthetic apparatus development and increase in the yield of faba bean green mass.

Common reed () is a cosmopolitan species, though its dieback is a worldwide phenomenon. In order to assess the evolutionary role of phenotypic plasticity in a successful plant, the values and plasticity of photophysiological traits of were investigated in the Lake Fertő wetlands at 5 sites with different degrees of reed degradation and along a seasonal sequence. On the one hand, along the established ecological degradation gradient, photophysiological traits of changed significantly, affecting plant productivity, although no consistent gradient-type trends were observed.

Background: Fruit photosynthetic apparatus development comprises a series of biological processes which is essential in determining fruit development and quality formation. However, the understanding of the regulation of fruit photosynthetic apparatus development remains poor.
Results: In this study, we identified a transcriptional factor SlBES2, the closest homolog of BES1 and BZR1 in tomato BES1 family, is highly expressed in fruit at mature green (MG) stage and exhibited transcriptional inhibition activity.

Both, Serendipita indica and AMF, show promise as sustainable biofertilizers for reforestation, improving nutrient uptake and stress tolerance, despite contrasting effects on photosynthetic capacity and biomass allocation. Reclaiming degraded areas is essential for biodiversity conservation and enhancing ecosystem services enhancement, especially when using native species. This study investigated Schinus terebinthifolius Raddi, a native Brazilian species, and its compatibility with plant growth-promoting microorganisms (PGPM), including an endophytic fungus (Serendipita indica) and a consortium of arbuscular mycorrhizal fungi (AMF), to identify effective strategies for reforestation in nutrient-poor environments.

Liquid crystal monomers (LCMs), the integral components in the manufacture of digital displays, have engendered environmental concerns due to extensive utilization and intensive emission. Despite their prevalence and ecotoxicity, the LCM impacts on plant growth and agricultural yield remain inadequately understood. In this study, we investigated the specific response mechanisms of tobacco, a pivotal agricultural crop and model plant, to four representative LCMs (2OdF3B, 5CB, 4PiMeOP, 2BzoCP) through integrative molecular and physiological approaches.

(), a significant ornamental plant species, is adversely affected by the severe soil heavy metal pollution resulting from rapid industrialization, particularly in terms of its growth environment. Cadmium (Cd), a representative heavy metal pollutant, poses a significant threat to plant growth and photosynthetic physiology. Despite the importance of understanding Cd stress resistance in rhododendrons, research in this area is limited.
