Bacteria recently isolated from walnut (Juglans regia L.) buds in Portugal has been identified as a new species of Xanthomonas. Interestingly, this new species baptised as Xanthomonas euroxanthea includes both pathogenic and non-pathogenic strains on walnut, constituting a unique model to address the emergence and evolution of pathogenicity in Xanthomonas.
The collaboration revealed that the symbiotic relationship between plants and fungi provides nitrates to plants, which could lead to reduced fertilizer use.
A research group has succeeded in greatly increasing the catalytic activity of Rubisco, the enzyme which fixes carbon from CO2 in plant photosynthesis. The research team also hypothesized the mechanism which determines the catalytic activity of Rubisco, based on structural analysis of the proteins.
An international team of researchers led by biologists has examined how seed formation is coordinated with fruit growth. In their report, they explain the genetic control mechanisms underlying the process. If you open up a pea pod, you will find that all of the peas inside are the same size and the same distance apart. The same is true of princess beans, runner beans and soybeans as well as various other peas and beans, and it also applies to non-pulses. This is surprising because both the seed size and number and the pod size differ substantially from one variety to the next.
Plants are able to keep growing indefinitely because they have tissues made of meristems–plant stem cells–which have the unique ability to transform themselves into the various specialized cells that make up the plant, dividing whenever appropriate and producing new cells of whatever type as needed. Meristems exist at the tips of all plants, allowing them to grow new stems or new roots, and, in trees, also in the trunk, where they add extra girth.
Scientists have led the first assessment of naturalised, invasive and potentially invasive plant species present in Laikipia County, Kenya, which hosts the highest populations of endangered large mammals in the country.
A team of scientists has completed one of the largest genetic analyses ever done of any agricultural crop to find desirable traits in wheat’s extensive and unexplored diversity.
Rhamnella in the family of Rhamnaceae is a small genus. To date, 10 species have been accepted into this genus. In field investigations, researchers found two Rhamnella populations from southwest Guangxi that belonged to the evergreen group but could not be ascribed to any of the evergreen Rhamnella species.
Arginine metabolism boosts to make a plant body complex, according to new research by a collaborative team in Japan. The findings might lead to a new understanding of amino acid metabolism with a specific role in plant morphogenesis.
For the First Time, Researchers Use CRISPR/Cas Molecular Scissors to Recombine Genes on a Chromosome. A new application of the CRISPR/Cas molecular scissors promises major progress in crop cultivation.
