Male and female reproductive structures play an important role in seed development in plants. Abnormalities in male or female reproductive structures can lead to sterility. In soybean, Glycine max (L.) Merr., about 75 sterility mutants have been identified and most of them have been mapped to chromosomes. Mapping results have shown that some chromosomal regions are hotspots for fertility genes. Fine mapping of some of the male-sterile, female-fertile mutants and male-sterile, femalesterile mutants resulted in identification of candidate genes for fertility. Sequence comparisons further helped in locating a few putative candidates. A CACTA- like transposable element that is responsible for ...

A Type Ii Metacaspase Interacts With Rps1-K-2 In Soybean And Analysis Of The Soybean Metacaspase Gene Family, James Andrew Baskett

Graduate Theses and Dissertations

Soybean suffers from the root and stem rot disease caused by the oomycete pathogen, Phytophthora sojae. A series of Rps genes confer Phytophthora resistance, and have been utilized in fighting this serious disease in soybean. Earlier we reported the cloning of the coiled coil-nucleotide binding-leucine rich repeat gene, Rps1-k-2. Here we report the identification of a type II metacaspase, Gmmc11 that interacted with the coiled-coil (CC) domain of Rps1-k-2 in vivo in yeast. The interaction was verified by conducting in vitro pull down assays in unpublished work. RNA interference of Gmmc11 in cotyledons resulted in loss of Phytophthora resistance. Gmmc11 ...
