Maize Genetics and Genomics
We are using two complementary approaches to identify useful genetic variation in landrace maize:
A) Gene driven: We are investigating candidate genes to gain a greater fundamental understanding of maize tolerance to abiotic stress
B) Phenotype driven: We are developing novel mapping populations and screening strategies to identify variation linked to enhanced abiotic stress tolerance
Currently, the major focus of our work is tolerance of maize to phosphate stress.Lab Group
Nidia Sanchez (Post-doc), Eliécer González (Masters) and Nancy Salazar (Masters) are characterizing the phosphate stress response of maize through functional mapping, and by study of candidate genes using both expression in model plant species, and reverse genetics in maize.
Tania Núñez (Masters; collaboration with the laboratory of Stewart Gillmor, Langebio) is characterizing maize genes involved in the regulation of transcription.
Dubois, a former Post-doc in the lab, initiated the generation of novel
landrace mapping populations. He is now working with Nunhems Seeds in Portland,
