Sclerotium rolfsii) is one of the major biotic constraints to peanut production in many countries, particularly under high temperature and humidity conditions. Developing disease-resistant cultivars represents a more sustainable strategy. To generate peanut germplasm integrating stem rot resistance and elite yield traits, this study utilized a recombinant inbred line(RIL) population, consisting of 242lines, derived from a cross between Zhonghua212(medium-seeded, resistant parent), and Zhonghua21(large-seeded, susceptible parent). A multi-environment evaluation was conducted for disease resistance profiling in the fields with artificial inoculation, and for yield-related traits assessment. The results indicated that twenty-two RIL lines exhibited consistent moderate resistance across all tested locations. Fifty RILs consistently expressed large pod(100-pod weight >180 g) and large seed(100-seed weight >80 g) phenotypes in two environments. Three elite RIL lines(BJF66, BJF119 and BJF137) combined moderate resistance with superior pod/seed traits,providing valuable genetic sources for breeding programs targeting both disease resistance and productivity. This study established a foundational germplasm pool for advancing stem rot resistant, high-yielding peanut varieties,aligning with sustainable agricultural practices to mitigate A. rolfsii threats.展开更多

In the central nervous system(CNS), the mTOR pathway regulates diverse aspects of neural development and function. Genetic mutations within the m TOR pathway lead to severe neurodevelopmental disorders, collectively known as “mTORopathies”(Crino, 2020). Dysfunctions of m TOR, including both its hyperactivation and hypoactivation, have also been implicated in a wide spectrum of other neurodevelopmental and neurodegenerative conditions, highlighting its importance in CNS health.展开更多
