| Elite varieties that have gone through long term breeding have probably fixed some elite alleles that occur with low frequencies in ancestral gene pool. Those elite alleles contribute to the elite performance of the elite varieties. Traditionally, geneticists use quantitative trait loci (QTL) linkage mapping and association mapping to identify those elite agronomic genes. However, QTL mapping r... more |

| Though discovered almost a century ago, Adenosine Triphosphate, or more simply known as ATP, is one of the most interesting yet not clearly understood elements in biology. Popularly called "molecular unit of currency" ATP is the primary transporter of energy for all living cells. Outside of cells however, several reports demonstrated that extracellular ATP plays important roles in the immune s... more |
