The International Grape Genomics Program (IGGP) is a collaborative genome project dedicated to determining the genome sequence of the grapevine Vitis vinifera. It is a multinational project involving research centers in Australia , Canada , Chile , France , Germany , Italy , South Africa , Spain , and the United States .
Experiments on Plant Hybridization" (German: Versuche über Pflanzen-Hybriden) is a seminal paper written in 1865 and published in 1866 [1] [2] by Gregor Mendel, an Augustinian friar considered to be the founder of modern genetics. The paper was the result after years spent studying genetic traits in Pisum sativum, the pea plant.
In genetics, a strain is said to be auxotrophic if it carries a mutation that renders it unable to synthesize an essential compound. For example, a yeast mutant with an inactivated uracil synthesis pathway gene is a uracil auxotroph (e.g., if the yeast Orotidine 5'-phosphate decarboxylase gene is inactivated, the resultant strain is a uracil ...
Plant breeding can be performed using many different techniques, ranging from the selection of the most desirable plants for propagation, to methods that make use of knowledge of genetics and chromosomes, to more complex molecular techniques. Genes in a plant are what determine what type of qualitative or quantitative traits it will have.
Mention of Beadle and Tatum's 1958 Nobel prize on the monument at the American Museum of Natural History in New York City.. Although some instances of errors in metabolism following Mendelian inheritance patterns were known earlier, beginning with the 1902 identification by Archibald Garrod of alkaptonuria as a Mendelian recessive trait, for the most part genetics could not be applied to ...
Wine-souring smoke from wildfires, grape-shriveling drought and global warming have all been playing an increasingly detrimental role in state vineyards for at least the last decade. But those ...
Even within one species, different strains have different transformation efficiencies, sometimes different by three orders of magnitude. For instance, when S. cerevisiae strains were transformed with 10 ug of plasmid YEp13, the strain DKD-5D-H yielded between 550 and 3115 colonies while strain OS1 yielded fewer than five colonies.

This test often involves crossing two pure-breeding strains, such as white-eyed flies, from separate origins. The process entails mating two flies, each from a different strain. The eye color of the resulting progeny determines the outcome of the test. If the progeny exhibit red eyes, it indicates that the two strains complement each other.
