About Rice Male Gamete Expression Database

In the past decades, Oryza sativa (rice) emerged as a model crop for the genetic studies not only because of its favorable genomic features but also as the major nutrient source for more than half of the world population. In the wake of growing population, rice productivity required a substantial increment. Among several factors, rice grain yield determinants are highly influenced by pollen biogenesis and activity. Abnormalities in anther or pollen development have been shown to result in male sterility or yield reduction in previous studies. Development and release of functional pollen at the proper time is crucial factor in successful reproduction and in creating genetic diversity. Also, selective breeding, release of genetically modified (GM) pollen and commercial development of hybrid lines relies on controlling pollen development and release. Another important observation was made on pollen was that evolutionary arising new genes are preferentially expressed in male reproductive organs and pollen could be act as “innovation incubator” that give rise to de novo genes. Hence, understanding on stage specific anther and pollen development is important for enhancing grain production.
