AI Article Synopsis
- Global warming negatively affects crop growth, particularly influencing the timing of flowering in plants like soybeans.
- A study using a warm, controlled environment (Climatron chamber) showed that two soybean varieties flowered earlier under elevated temperatures compared to natural field conditions.
- The research found that higher temperatures increased the expression of flowering activator genes and decreased repressor genes, indicating soybeans can adapt their genetic response to environmental changes regardless of day length.
Article Abstract
Global warming has an impact on crop growth and development. Flowering time is particularly sensitive to environmental factors such as day length and temperature. In this study, we investigated the effects of global warming on flowering using an open-top Climatron chamber, which has a higher temperature and CO concentration than in the field. Two different soybean cultivars, Williams 82 and IT153414, which exhibited different flowering times, were promoted flowering in the open-top Climatron chamber than in the field. We more specifically examined the expression patterns of soybean flowering genes on the molecular level under high-temperature conditions. The elevated temperature induced the expression of soybean floral activators, and as well as a set of genes. In contrast, it suppressed floral repressors, and homologs. Moreover, high-temperature conditions affected the expression of these flowering genes in a day length-independent manner. Taken together, our data suggest that soybean plants properly respond and adapt to changing environments by modulating the expression of a set of flowering genes in the photoperiod pathway for the successful production of seeds and offspring.

Flower appearance stands as a key characteristic of flowering plants and is closely linked to their ornamental value. Phytohormone Gibberellin (GA), essential for plant growth and development are widely reported for expansion in flower. DELLA proteins are known to negatively regulate GA signaling and influences plant growth and development through the regulation of cell expansion.

Common ash (Fraxinus excelsior) is under intensive attack from the invasive alien pathogenic fungus Hymenoscyphus fraxineus, causing ash dieback at epidemic levels throughout Europe. Previous studies have found significant genetic variation among genotypes in ash dieback susceptibility and that host phenology, such as autumn yellowing, is correlated with susceptibility of ash trees to H. fraxineus; however, the genomic basis of ash dieback tolerance in F.

Light is one of the most important environmental factors that affect plant growth and development. It also stimulates anthocyanin biosynthesis in plants. However, the precise molecular mechanisms through which light regulates anthocyanin biosynthesis, particularly in non-model plant species, remain poorly understood.
