“…Plants from the High IVDMD and low IVDMD switchgrass populations developed by the USDA-ARS breeding program at Lincoln, NE, could be used to identify QTLs that control this complex trait in switchgrass and also identify QTLs affecting winter survival. Research to date indicates that genes and their structural organization within genomes of Gramineae have a high degree of similarity (Stuber et al, 1999). Comparative maps and mapping information from other species should be very useful in developing markers for marker-assisted selection in switchgrass.…”

Abstract:Much of the research on the genetic modification of herbaceous plant cell walls has been conducted to improve the utilization of forages by ruminant livestock. The rumen of these animals is basically an anaerobic fermentation vat in which the microflora break down the complex polysaccharides of plant cell walls into simpler compounds that can be further digested and absorbed by the mammalian digestive system. Research on improving the forage digestibility of switchgrass, Panicum virgatum L., and other herbaceous species has demonstrated that genetic improvements can be made in forage quality that can have significant economic value. To meet future energy needs, herbaceous biomass will need to be converted into a liquid fuel, probably ethanol, via conversion technologies still under development. If feedstock quality can be genetically improved, the economics and efficiency of the conversion processes could be significantly enhanced. Improving an agricultural product for improved end product use via genetic modification requires knowledge of desired quality attributes, the relative economic value of the quality parameters in relation to yield, genetic variation for the desired traits, or for molecular breeding, knowledge of genes to suppress or add, and knowledge of any associated negative consequences of genetic manipulation. Because conversion technology is still under development, desirable plant feedstock characteristics have not been completely delineated. Some traits such as cellulose and lignin concentration will undoubtably be important. Once traits that affect biomass feedstock conversion are identified, it will be highly feasible to genetically modify the feedstock quality of herbaceous plants using both conventional and molecular breeding techniques. The use of molecular markers and transformation technology will greatly enhance the capability of breeders to modify the morphologic structure and cell walls of herbaceous species. It will be necessary to monitor gene flow to remnant wild populations of biomass plants and have strategies available to curtail gene flow if it becomes a potential problem. It will also be necessary to monitor plant survival and longterm productivity as affected by these genetic changes to herbaceous species.

“…At the moment, of course, it is necessary to combine conventional analyses of plant material with marker-assisted selection techniques. It is proposed that the use of marker data together with phenotypic evaluations provides instruments suitable for more effective breeding (GRANER et al 2000;STUBER et al 1999;RIBAUT & BETRAN 2000;SHARIFLOU et al 2001).…”

Abstract:In recent years, molecular markers have been developed based on the more detailed knowledge of genome structure. Considerable emphasis has been laid on the use of molecular markers in practical breeding and genotype identification. This review attempts to give an account of different molecular markers currently available for genome mapping and for tagging different traits -restriction fragment length polymorphisms (RFLPs), random amplified polymorphic DNAs (RAPDs), amplified fragment length polymorphisms (AFLPs) and microsatellites. Other markers, expressed sequence tags (ESTs) and single nucleotide polymorphisms (SNPs) are also mentioned. The importance of structural, functional genomic and comparative mapping is also discussed.

“…Pour que la sélection assistée par marqueurs (SAM) ou la sélection à l'aide de marqueurs soit efficace le génome doit être saturé avec des marqueurs uniformément espacés et/ou présentant un haut niveau de déséquilibre de liaison [1,2]. Or, alors que sa diversité morphologique est importante, l'arachide répond mal aux techniques de marquage de l'ADN [3,4].…”
