Notes de l'éditeur
- CIMMYT grew out of a pilot program sponsored by the Mexican government and the Rockefeller Foundation in the 1940s and 1950s aimed at raising farm productivity in Mexico. The wheat specialist in that program, Norman Borlaug, worked with Mexican researchers and farmers to develop hardier, short-stemmed wheat varieties that resisted devastating rust diseases and yielded much more grain than traditional varieties. The new wheat lines were bred and selected at various Mexican locations in a range of climate conditions, which meant they were adaptable to a range of farm settings. The higher yielding varieties helped Mexico attain self-sufficiency in wheat production in the 1950s. Additionally, the varieties were imported by India and Pakistan in the 1960s to stave off famine, soon bringing those countries record harvests. This led to the widespread adoption of improved varieties and farming practices, which became known as the “Green Revolution.” CIMMYT was formally launched as an international organization in 1966. Borlaug, who worked at CIMMYT as a wheat scientist and research leader until 1979, received the 1970 Nobel Peace Prize
- ICRISAT (Rajeev Varshney) led international sequencing consortium to sequence genomes of pigeonpea, chickpea and pearl millet.
- Rajeev co-led genome seqencing groundnut, mungbean, sesame, and Adzuki bean.
- Now, ICRISAT is leading The 3000 Chickpea Genome Sequencing Initiative funded mainly by Ministry of Agriculture, Government of India and also from Australia and Canada. In addition to ICRISAT, IIPR, Junagadh Agricultural Uni, Rajasthan Agricultural Research Institute, Regional Agricultural Research Station-Sehore, ICARDA, Uni of Western Australia and Uni of Saskatchewan are the partners in this project. They are sequencing 3000 chickpea lines and also phenotyping this collection at six different locations. CNV = large segments of DNA, ranging in size from thousands to millions of DNA bases, varying in copy-number (more than two in diploid); they are copy number variations or CNVs
- That allows GWAS in Maize and GS in Wheat Association Mapping in W & M Interest of private partners (big 6), ARIs (Cornell); contractual and IP issues on “in silico” or “dematerialized” germplam information
- Excellence in science and research/ published in Nature in feb 2016
- Construct include NASFer-274 containing rice nicotianamine synthase (OsNAS2) or soybean ferritin (SferH-1) genes and both of them in the same construct Rigorous selection was applied to 1,689 IR64 transgenic events for insert cleanliness and, trait and agronomic performances. Single locus insertion without a yield penalty or altered grain quality were selected
- 10 research centers and 6 countries (North / South)
- C3 carbon fixation is one of three metabolic pathways for carbon fixation in photosynthesis, along with C4 and CAM. This process converts carbon dioxide and ribulose bisphosphate (RuBP, a 5-carbon sugar) into 3-phosphoglycerate through the following reaction In the majority of plants, including rice, CO2 is first fixed into a compound with three carbons (C3) by the photosynthetic enzyme ribulose bisphosphate carboxylase oxygenase (Rubisco) The fundamentals of C4 photosynthesis are shown in a simplified form in the figure on the right. The photosynthesis processes of C4 plants are divided between mesophyll and bundle sheath cells. Two steps of C4 photosynthesis that occur in the mesophyll cells are the light-dependent reactions and a preliminary fixation of CO2 into a molecule called malate (C4). Rubisco is inherently inefficient because it can also catalyze a reaction with oxygen from the air, in a wasteful process known as photorespiration (rather than photosynthesis). At temperatures above 20°C, there is increasing competition by oxygen (O2), with a dramatic reduction in CO2 fixation and photosynthetic efficiency. While all this is happening, water is escaping from the leaves while the CO2 is diffusing in. Thus, in the hot tropics where most rice is grown, photosynthesis becomes very inefficient.
- C4 plants are more efficient in carbon dioxide concentration that results in increased efficiency in water and nitrogen use and improved adaptation to hotter and dryer environments. In nature, this has occurred more than 50 times in a wide range of flowering plants, indicating that, despite being complex, it is a relatively easy pathway to evolve. Kranz (C4) anatomy arose before the C4 biochemistry within the bundle sheath cell, in response to photorespiration. Therefore, strategies to engineer C4 photosynthesis should first address the introduction of Kranz anatomy (= wreath bundle sheath cells) into C3 plants.
- Long term project Funded by BMGF for IRRI
- A U.S. National Science Foundation (NSF)–funded collaborative project between Yale and Cornell universities is using laser micro-dissection technologies to capture specific cell types in sorghum, maize, and rice leaves for further analysis of proteins and gene transcripts. A quantitative inventory of these molecules in each cell type will provide information regarding the regulation of gene expression and will explain how sorghum, maize, and rice plants differ in photosynthesis and in other cellular functions. We intend to integrate information from the NSF and this project using bioinformatics and systems modeling. At Washington State University and the University of Toronto, extensive research is being conducted on the structural and biochemical diversity among the 19 families of plants found to have C4 species, and on the progressive evolution from C3 to C3-C4 intermediates, and to C4 photosynthesis. Julian Hibberd (Cambridge) and Peter Westhoff (Dusseldorf) have been developing molecular tools to enable cell-specific genes to be introduced into rice via transformation.
