Bibechana Adhikari will be presenting her research, "Analysis of early endosperm development in maize,” in the IPB 2018 student fall seminar series (PLBIO 696). Event will be located in 1420 Molecular Biology Building.
Endosperm is formed as a result of second fertilization in flowering plants. It is an absorptive structure that functions to provide nutrient and protection to developing embryo and supports seedling germination. Endosperm in cereal grain contains large amounts of carbohydrates and protein storage product that serves as an important source of food, feed, and industrial raw materials. The key molecular genes/TFs involved in directing the pattern of early endosperm development has been elusive. To characterize this, we are focusing on few endosperm mutants that show very interesting phenotype. Early endosperm development (0-15 days after pollination) in maize is a critical formative period when kernel storage capacity is established, and the time kernel development is most sensitive to stresses such as drought. One of the other goal is to analyze the effect of drought stress on early developmental stages to reveal the mechanism by which drought impacts GRNs and yield. Therefore, an understanding of various key contributors that are involved in endosperm development will contribute to improving cereal grain yield and quality that will be directly or indirectly beneficial for human nutrition and economic development.
