Research Project:
USING GENOMIC/PROTEOMIC TECHNOLOGIES TO IMPROVE QUALITY AND STRESS TOLERANCE OF CROP SPECIES
Location:
U.S. Plant, Soil and Nutrition Research
Project Number: 1907-21000-012-00
Project Type:
Appropriated
Start Date: Oct 01, 2002
End Date: Aug 31, 2006
Objective:
1) Study the molecular basis and regulation of carotenoid accumulation in plant tissues/organs which normally accumulate either low or high levels of carotenoids; 2) improve the aluminum tolerance of grain crops for cultivation on acid soils; 3) study the molecular basis for plant heavy metal accumulation and tolerance; 4) conduct research in advanced technology development in proteomics and other areas related to functional genomics to apply to crop and microbial research projects in the MU.
Approach:
1) Use molecular biology and genomics/proteomics approaches to study the metabolism and accumulation of organic constituents of plant foods that impact human nutrition and health. 2) The cellular physiology, molecular biology and electrophysiology of micronutrient and heavy metal uptake and nutrition will be studied, in order to ultimately develop micronutrient efficient crops as well as plants better suited for the remediation of metal-contaminated soils. 3)Physiological, genetic and genomics/proteomics approaches will be used to elucidate plant tolerance mechanisms to toxic levels of aluminum (Al) found in acid soils that predominate throughout the world, with an ultimate goal of isolating Al tolerance genes for use in developing improved transgenic crops for cultivation on acid soils. 4) The development and advancement of proteomics technologies (e.g., protein purification/identification via mass spectrometry and primary structure determination) to be used to further the research on existing agricultural problems on microbial and crop genomics in the MU.
