Hence, present study evaluates 3115 safflower accessions from Indian National Gene Bank, including cultivars, develop manageable accessions, with similar variations studied. A ...

Genetically modified (GM) plants are one of the great achievements of modern biotechnology in agriculture, which their cultivation has been increased in recent years.

Motivated by data demonstrating fluctuating relative and absolute fitnesses for white- versus blue-flowered morphs of the desert annual Linanthus parryae, we present conditions under which temporally fluctuating selection and fluctuating contributions to a persistent seed bank will maintain a stable single-locus polymorphism. In L. parryae, blue flower color is determined by a single dominant a...

In particular we present results on a tree-bank grammar base...

A unified bank, one that invests in both liquid and illiquid assets, can easily avoid runs but it still faces a small probability of non-run rationing of depositors. In a separated financial system, the bank only holds relatively liquid assets; it is subject to runs with small probability, but because of its overinvestment in the liqu...
