Researchers Reveal Novel Key Gene Controlling Salt Tolerance in Rice

Soil salinization poses a serious threat to global rice production. At present, the natural‑variation‑based genetic basis of rice salt tolerance remains poorly understood, and only a handful of major genes related to salt tolerance have been functionally characterized. It is critical to identify key gene modules in salt signaling pathways. In a study published in Developmental Cell on August 28, a

Study Traces Origin of African Succulent Euphorbia Section Monadenium to Early Miocene

The Euphorbia section Monadenium comprises approximately 90 species that are restricted to tropical Africa, with the greatest diversity found in East Africa. Members of this section range from geophytes and perennial herbs to succulent shrubs and small trees, many of which are endemic to arid or seasonally dry habitats. However, their evolutionary and biogeographical history remains poorly underst

Trait-Based Framework Accelerates Breeding of Light Wood Trees

Balsa wood is one of the world's fastest-growing and most commercially valuable tropical timber species. Renowned as the lightest commercial timber, it has experienced soaring global demand. However, traditional propagation techniques, such as tissue culture and cuttings, have proven difficult due to the species' abundant leaf hairs and mucilage secretion. This makes controlled hybridization the m

Researchers Develop Stepwise Evaporation Method to Reduce Contact Resistance in Transistors

Metals, semiconductors and insulators are fundamental components of modern electronics. However, efforts to improve device performance have largely focused on semiconductor quality, while metal crystallinity has received far less attention. As transistor dimensions continue to shrink, though, structural disorder in metals and at metal-semiconductor interfaces increasingly impedes carrier injection

New Framework Advances Spray-Induced Gene Silencing Toward Industrialization

A research team has recently published a systematic reference framework for advancing Spray-Induced Gene Silencing (SIGS) from proof-of-concept toward industrialization. Led by Prof. ZHANG Tao from the Xinjiang Institute of Ecology and Geography (XIEG) of the Chinese Academy of Sciences (CAS), in collaboration with researchers from the Institute of Germplasm Resources and Biotechnology under the T

Researchers Reveal How Gatekeeper Enzyme UGCG Controls Glycosphingolipid Synthesis

Glycosphingolipids (GSLs) are sugar-containing membrane lipids that help organize cell surfaces and regulate signaling, immune recognition, differentiation and neuronal function. Human cells produce several hundred GSL species through stepwise modification of their sugar groups, and this diversity begins with a single committed reaction, in which uridine diphosphate glucose (UDP-glucose) ceramide

Rewiring Rumen Hydrogen Economy: New Strategy for Methane Mitigation and Sustainable Livestock Production

Methane emissions from cattle and sheep contribute to global greenhouse gas emissions and reflect a loss of dietary energy that could otherwise support animal growth and productivity, which is a major challenge for sustainable livestock production. M ost existing approaches to reduce methane emissions focus primarily on suppressing methanogenesis. In a study published in The Innovation , a researc

Researchers Develop Bridge RNA-guided Large-fragment Editing System for Cross-kingdom Precise Genome Manipulation

Precise manipulation of large genomic fragments is a critical need in crop breeding and synthetic biology. In crop genomes, superior traits are often associated with structural variations. However, existing large-fragment editing tools such as CRISPR-Cas systems and site-specific recombinases have limitations. In 2024, the development of the bridge RNA-guided IS110-family recombinase system provid

CIP2A Found to Link DNA Repair and Tumor Sensitivity to Radiotherapy

DNA double-strand breaks (DSBs) are posing serious threats to genome stability. During mitosis, cells mainly rely on polymerase theta (Polθ) -mediated repair to fix these breaks. However, how the CIP2A-TOPBP1 complex regulates this process remains unclear.

Researchers Reveal How Auxin Establishes Pistil Boundary by Degrading Key Transcription Factor

Have you ever wondered how a flower ensures that it's pollen-catching "landing pad" (the stigma) stays neatly separated from the "pollen tube highway" beneath it (the style)? This clear boundary is crucial for plant reproduction, but for decades, biologists didn't know how it was drawn.
