Soybeans grown alongside maize often face shading stress that reduces yield, yet some cultivars can thrive under low light. Scientists have now uncovered a comprehensive genetic network that controls this shade tolerance, moving beyond the traditional single-gene perspective. By integrating forward genome-wide association and reverse transcriptomic analyses, researchers identified more than 200 causal genes and over 7,800 expressed genes involved in soybean’s shade response. These genes function in a coordinated sequence—from light signal detection to metabolic adaptation—forming a multilayered regulatory system. The findings open a new pathway toward breeding high-yield, shade-tolerant soybeans for intercropping systems worldwide.

An ancient genetic event may hold the key to how plants survive in metal-contaminated environments. Scientists have discovered that a duplication of phytochelatin synthase (PCS) genes—crucial enzymes for detoxifying toxic metals—occurred millions of years ago and remains conserved in flowering plants today. These twin gene copies, known as D1 and D2, evolved distinct but complementary functions: while D1 plays a general role in detoxification, D2 exhibits exceptional catalytic activity against cadmium and arsenic. Functional tests in Malus domestica (MdPCS1, MdPCS2) and Medicago truncatula (MtPCS1, MtPCS2) revealed that both copies are indispensable for maintaining metal balance, unveiling a deep evolutionary strategy for resilience.

In a pioneering exploration of the evolving landscape of carbon fiber composite material recycling, researchers are leveraging bibliometric analysis to uncover the latest advancements and emerging hotspots in this critical field. The study, titled "Research Advances and Hotspot Evolution of Carbon Fiber Composite Material Recycling Based on Bibliometrics Analysis," is led by Prof. Da Chen from the Science and Technology Innovation Research Institute at the Civil Aviation University of China in Tianjin, China, and the Tianjin Engineering Research Center of Civil Aviation Energy-Environment and Green Development. This comprehensive analysis offers valuable insights into the current state and future directions of carbon fiber recycling research.

The secret to tomato size lies within the flower's core. Scientists have discovered that the gene SlKNUCKLES (SlKNU), which encodes a zinc finger protein, serves as a key switch that determines fruit size by regulating floral meristem activity—the tissue responsible for forming reproductive organs. 

The size of a tomato fruit begins with its flower. Scientists have revealed that the gene SlKNUCKLES (SlKNU), which encodes a zinc finger protein, plays a decisive role in determining tomato fruit size by regulating the activity of floral meristems—the tissue that gives rise to reproductive organs.
