Roxb. is a special tropical spice crop resource with broad development prospects. It is widely cultivated under a (Willd. ex A. Juss.) Muell. Arg. canopy to improve the comprehensive benefits to plantations in Hainan Provence, China. However, the effects of intercropping with on the component number and relative contents of volatile substances in different categories in the leaves are still unknown. Therefore, a and intercropping experiment was set up to clarify the differences between several cultivated patterns on volatile substances in the leaves, and the key regulatory factors of volatile substances. The results showed that the soil pH was significantly decreased, while soil bulk density, alkali-hydrolyzable nitrogen and available phosphorus contents were significantly increased under the intercropping pattern. The component numbers of esters in volatile substances were increased by 6.20%, while the component numbers of ketones were decreased by 4.26% under the intercropping pattern. Compared with the monoculture, the relative contents of pyrroles, esters and furanones were significantly increased by 8.83%, 2.30% and 8.27%, respectively, while the relative contents of ketones, furans and hydrocarbons were decreased by 1.01%, 10.55% and 9.16% under the intercropping pattern, respectively. The relative contents of pyrroles, esters, furanones, ketones, furans and hydrocarbons were associated with changes in soil pH, soil available phosphorus content and air temperature. The results indicated that the reduction in soil pH and enhancement in soil-available phosphorus may be the main reasons for promoting the relative content of pyrroles and reducing the relative content of hydrocarbons under an intercropping pattern. Overall, intercropping with could not only improve soil properties, but also significantly increase the relative contents of the main volatile substances in leaves, which could provide a theoretical basis for the application and promotion of high-quality production patterns of .

Background: Spinal muscular atrophy (SMA) is a motor neuron disease with loss of musculature, which is replaced by fat. Previous magnetic resonance imaging (MRI) studies have focused on imaging muscles either in lower or upper extremities, but whole-body MRI can provide additional information on the involvement pattern. This study examined whole-body muscle fat replacement and the relationship between muscle structure, function, and bulbar symptoms.

Rice tillering determines grain yield, yet the molecular regulatory network is still limited. In this study, we demonstrated that the transcription factor OsMADS60 promotes the expression of the auxin transporter OsPIN5b to affect auxin distribution and inhibit rice tillering and grain yield. Natural variation was observed in the promoter region of OsMADS60, with its expression level negatively correlated with tiller number and inducible by auxin.

The widely distributed heat shock protein DnaJ is renowned for its pivotal role in enhancing thermal tolerance in plants; however, its involvement in drought tolerance remains elusive. In this study, genes encoding DnaJ1 were cloned from drought-resistant wild tomato (Solanum pennellii) and drought-sensitive cultivated tomato (Solanum lycopersicum). SpDnaJ1 and SlDnaJ1 from both tomato species were localized in the chloroplast, and their gene expression was induced by various abiotic stresses.

Background: With the growing population of older adults and the prevalence of negative attitudes towards them, the issue of ageism and its health and economic impacts in both benevolent and hostile contexts warrants special attention. It is crucial to examine the attitudes of other age groups towards older adults across different societies. Particularly, the benevolent dimension of ageism, which has been less explored in research, requires more focus.

Background: Common bean (Phaseolus vulgaris L.) is a thermophilic crop, and exposure to cold stress can significantly impact their yield and quality. To elucidate the impact of cold stress on cold-tolerant 'Wei Yuan' (WY) and cold-sensitive 'Bai Bu Lao' (BBL) of common bean, the mechanism of cold tolerance was studied by physiological and biochemical and multi-omics analysis.
