Tibetan barley (Hordeum vulgare) accounts for over 70% of the total food production in the Tibetan Plateau. However, continuous cropping of Tibetan barley causes soil degradation, reduces soil quality and causes yield decline. Here we explore the benefits of crop rotation with wheat and rape to improve crop yield and soil quality.

In this study, we investigated the diversity of seed endophytic microbes in two rice varieties, the cold-sensitive CB9 and the cold-tolerant JG117. Our results revealed significant differences in the abundance of Microbacteriaceae, with JG117 exhibiting a higher abundance under both cold stress and room temperature conditions compared to CB9.

- Branching and tillering in wheat are crucial for plant structure and yield but are influenced by various internal and external factors; understanding these processes is limited.
- This research discovered a new regulator of wheat tillering using a refined method called uni-BSA, which minimizes genetic noise, and identified a gene linked to reduced tillers due to issues in bud growth.
- The study demonstrates how this gene impacts sucrose levels in plants, crucial for bud development, and presents the uni-BSA method as a valuable tool for identifying significant agronomic genes, aiding in crop improvement efforts.
Article Synopsis
- Axillary meristems (AMs) play a crucial role in determining the number of shoots or tillers in plants, affecting their overall structure and crop yields.
- The review focuses on the genetic and hormonal factors involved in AM initiation, mainly using research from Arabidopsis and rice as examples.
- It highlights key genes like LATERAL SUPPRESSOR (LAS) and discusses the relationship between AM and shoot apical meristem (SAM), while also considering the potential of new research methods to enhance crop productivity.
Biosolids are considered an alternative to chemical fertilizers due to their rich nutrients. However, long-term biosolids application can lead to heavy metals accumulation, which severely affects soil microbial community compositions. The factors influencing soil microbial community assembly were explored under a 16-year long-term experiment with biosolids applications.
