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...
Researchers found that Arabidopsis plants respond differently to light and temperature signals, with one gene focused on photosynthesis and the other sensitive to temperature. This discovery suggests that plants have multiple internal clocks operating within a single tissue, allowing them to make critical decisions about flowering.
Researchers identified a new transcriptional regulator of CBF genes, ICE1, which increases cold tolerance in Arabidopsis plants. The discovery is expected to provide a new way to improve the ability of domesticated crops to survive in cold temperatures.
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 are using Arabidopsis plant mutants to study salt stress in plants and potential connections to HIV research. Mutants with altered genes have been identified, offering insights into the mechanisms behind these complex conditions.
Researchers found mostly beneficial gene substitutions in fruit fly Drosophila, but mostly detrimental substitutions in mustard weed Arabidopsis. The study attributes this difference to the Arabidopsis mating system of partial self-fertilization, which reduces effective population size and increases deleterious mutations.
Researchers will study the functions of beta-glucosidase and beta-galactosidase gene families in Arabidopsis, a small but useful model for understanding genetic processes. The goal is to determine the functions of approximately 25,000 genes, which can be extrapolated to other plants like wheat and soybeans.
Researchers identified complete set of pollen coat proteins, revealing genetic clues to plant mating and self-recognition. The study found rapid divergence of mating genes across species boundaries, shedding light on evolutionary processes.
The completed Arabidopsis genome provides a roadmap for understanding plants to improve nutrition and health. Monsanto contributed to the effort through Cereon Genomics, releasing over 40,000 genetic markers that increased the resolution of genetic maps used by researchers.
The international Arabidopsis Genome Initiative has successfully completed the sequencing of the entire genome of Arabidopsis thaliana, a powerful tool in plant molecular biology. The study reveals vast chromosomal regions have been duplicated in the genome, and approximately 70% of genes can be functionally predicted.
The complete genome sequence of Arabidopsis thaliana reveals clues to genetic behavior in plants and animals, with potential applications for agriculture and medicine. The public domain genome catalog provides a resource for scientists worldwide.
The Fred Hutchinson Cancer Research Center is developing a new strategy for obtaining plants with desirable genetic mutations using the TILLING method. This approach allows for rapid and large-scale analysis of mutations without introducing genetically modified material.
Scientists have found that the gene order in Arabidopsis, a model eudicot, is not preserved in rice, a model monocot. This discovery reveals an evolutionary divide between dicots and monocots, cautioning against using Arabidopsis genome for understanding cereal crops like rice and wheat.
