Induced Polyploidy: A Tool for Forage Species Improvement

نویسندگان

چکیده

Polyploidy means having more than two basic sets of chromosomes. Polyploid plants may be artificially obtained through chemical, physical and biological (2n gametes) methods. This approach allows an increased gene scope expression, thus resulting in phenotypic changes such as yield product quality. Nonetheless, breeding new cultivars induced polyploidy should overcome deleterious effects that are partly contributed by genome epigenome instability after polyploidization. Furthermore, shortening the time required from early chromosome set doubling to final selection high yielding superior polyploids is a must. Despite these hurdles, plant breeders have successfully polyploid bred-germplasm broad range forages optimizing methods, concentration time, particularly when using colchicine. These experimental valuable tool for understanding which seems driven dosage dependent altered regulation epigenetic changes. Isozymes DNA-based markers facilitated identification rare alleles particular loci compared with diploids, also explained their heterozygosity, plasticity adaptability diverse environments. Experimentally germplasm could enhance fresh herbage quality, e.g., leaf protein content, total soluble solids, water carbohydrates sucrose content. Offspring experimentally hybrids undergo several generations improve performance stability.

Polyploidy and Crop Improvement

All crop plants are polyploid and some genomes have been duplicated more recently than others. Advancements in cytogenetic and molecular tools, including high-density genetic mapping, fl orescent in situ hybridization, and genome and EST sequencing, have enabled new insights into genome composition and the history of genome duplications in crop plants. We review this evidence and discuss the re...

Species interactions and plant polyploidy.

Polyploidy is a common mode of speciation that can have far-reaching consequences for plant ecology and evolution. Because polyploidy can induce an array of phenotypic changes, there can be cascading effects on interactions with other species. These interactions, in turn, can have reciprocal effects on polyploid plants, potentially impacting their establishment and persistence. Although there i...

SOUTHERN PASTURE & FORAGE CROP IMPROVEMENT CONFERENCE Lexington

Nothing is more important for effective nodulation of legumes that the availability of sufficient numbers of an infective strain of rhizobia in the root zone of seedlings. In some cases, the soil will contain sufficient numbers of infective rhizobia but modern approaches to the use of genetically superior strains of rhizobia practically demands the use of some means of inoculation, thus raising...

Genetic Engineering for the Improvement of Forage Grass Quality

The forage quality of warm season perennial grasses grown in the Southern States, subtropics, and the tropics is often inadequate and is a major limitation to satisfactory animal performance. Quality improvement of those warm season grasses has been a high priority research objective in breeding programs. Hammond (1987) pointed out that C4 tropical and subtropical grasses generally have lower q...
