The genomes of all higher life forms are stored in the cell nucleus on chromosomes. Chromosomes are composed of strands of the DNA molecule. The genetic information itself is encoded in a sequence of adjacent base pairs of the molecules adenine (A), cytosine (C), guanine (G) and thymine (T).
Widespread fungal disease in plants can be controlled with a commercially available chemical that has been primarily used in medicine until now. In a comprehensive experiment the team has uncovered a new metabolic pathway that can be disrupted with this chemical, thus preventing many known plant fungi from invading the host plant.
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.
First international assessment of the protection state of mostly ‘untouched’ forests in Europe. An expansion of the protected areas by only about 1% would sufficiently protect most remaining primary forests in Europe.
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.
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.
Scientists have characterized a sucrose transporter protein found in common beans. The recently discovered protein could help us understand how beans tolerate hot temperatures.
