Researchers at Purdue University have identified a gene that controls the production of plants' outermost protective coating. By manipulating this gene, they may be able to create crops with increased drought resistance. The study found that altering the gene's expression can result in thicker or more rigid cuticles, reducing water los...
The UC Riverside-led study unveils the genome sequence of Neurospora, a model organism for understanding fungi's role in agriculture, medicine and the environment. The research reveals 10,000 predicted genes, with significant implications for developing new antibiotics and disease control strategies.
Scientists have identified two major gene duplication events in Arabidopsis, a small flowering plant, which occurred 200 million and 80 million years ago. These events are believed to be responsible for the differences among modern plants.
Researchers have discovered that the FoxM1B gene plays a crucial role in tissue healing and regeneration. The study found that the gene is essential for cells to divide and multiply, allowing tissues to repair and regenerate. Without FoxM1B, DNA duplication fails, leading to accelerated aging and age-related diseases.
The sequenced rice genome contains 45,000-56,000 genes, which could provide a roadmap for improving cereal crops like maize, wheat, and barley. The research aims to increase crop yields and vitamin content, addressing global food shortages and hunger.
A new study from the University of Michigan reveals how a duplicated gene in leaf-eating monkeys has evolved to improve digestion efficiency. The researchers found that the duplicated gene allows the monkeys to better cope with an acidic environment, suggesting a key adaptation to their unusual diet.
Researchers have confirmed an estimated 30,000 human genes using a comparative analysis of human chromosome 19 with similar sections of mouse DNA. The study found over 300 additional human genes and confirmed the existence of other computer-predicted genes.
Researchers have discovered a new mechanism for genetic duplication, where duplicated regions are inserted into distant chromosomal sites. This new form of duplication implies that the human genome has more ways of rearranging itself than previously thought.
Researchers propose a novel mechanism for pericentromeric duplication, which has pulled disparate genes to the central regions of hominoid chromosomes. This process may have created new human genes and contributed to evolutionary divergence from Old World primates.
