Plant height, one of the most important factors for plant architectures, is closely related with some important traits such as plant density, lodging resistance and yields.. In the present study, 201 QTLs related to plant height of soybean from database and references were analyzed. The results revealed that 15 consensus QTLs located on chromosomes 6, 7, 11, 13, and 18 were identified after physical integrations and Meta analysis using the software BioMercator 2.1. Moreover, "Overview" method was used to optimize these QTLs based on statistic analysis. Some of the valid QTL regions were narrowed down to the 0.1 cM and mapped on certain chromosomes. Furthermore, the functions of all genes located in these confidence regions were predicted and 17 candidate genes that might be related to plant height were identified. These results would lay a foundation for fine mapping of QTLs related to plant height and marker-assisted breeding in soybean.

Application of herbicide-degrading bacteria is an effective strategy to remove herbicide in soil. However, the ability of bacteria to degrade a herbicide is often severely limited in the presence of other pesticide. In this study, the atrazine-degrading strain Klebsiella varicola FH-1 and acetochlor-degrading strain Bacillus Aryabhatti LY-4 were used as parent strains to construct the recombinant RH-92 strain through protoplast fusion technology.

Plant height is a key trait that significantly influences plant architecture, disease resistance, adaptability to mechanical cultivation, and overall economic yield. Galactinol synthase (GolS) is a crucial enzyme involved in the biosynthesis of raffinose family oligosaccharides (RFOs). It plays a significant role in carbohydrate transport and storage, combating abiotic and biotic stresses, and regulating plant growth and development.

Background: Non-structural carbohydrates (NSCs) are key substances for metabolic processes in plants, providing energy for growth, development, and responses to environmental stress. Pruning mother bamboo in a clump can significantly affect the NSCs allocation of new shoots, thereby affecting their growth. Moso bamboo (Phyllostachys edulis) is an important economic bamboo species with a highest planting area in China.

Climate warming has become a hot issue of common concern all over the world, and wind energy has become an important clean energy source. Wind farms, usually built in wild lands like grassland, may cause damage to the initial ecosystem and biodiversity. However, the impact of wind farms on the functional diversity of plant communities remains a subject with unclear outcomes.

During the mating season, reproductive individuals of numerous insect species gather in rendezvous areas, which increases mating opportunities. Male hymenopterans often have to move considerable distances during a particular season, searching or waiting for receptive females. Such behavior is likely driven by a complex combination of individual and species-specific traits, environmental influence, and landscape cues.
