Linkage Studies in Gossypium. II. Altered Recombination Values in a Linkage Group of Allotetraploid G. Hirsutum L. as a Result of Transferred Diploid Species Genes.
ACCORDING to STEPHENS (1950) speciation in the genus Gossypium occurs both by cryptic structural differentiation of chromosomes and by major gene substitution and mutation. In the first paper of this series RHYNE (1958) reported a sizeable reduction of recombination values within linkage groups following a transfer of intact diploid Gossypium linkage groups into allotetraploid G. hirsutum. Thes...
متن کاملComparative bioinformatics analysis of a wild diploid Gossypium with two cultivated allotetraploid species
Background: Gossypium thurberi is a wild diploid species that has been used to improve cultivated allotetraploid cotton. G. thurberi belongs to D genome, which is an important wild bio-source for the cotton breeding and genetic research. To a certain degree, chloroplast DNA sequence information are a versatile tool for species identification and phylogenetic implications in plants. Different ch...
متن کاملA linkage group of four genes related to morphological traits in lentil (Lens culinaris Medik.)
Monogenic inheritance and linkage among four morphological traits of lentil were established on the basis of F1 observations and analysis of 204 F2 plants in a cross for development of pubescence on peduncle, 228 F2 plants in a cross for tendril formation, 574 F2 plants in 5 crosses for flower numbers per peduncle and 464 F2 plants in 4 crosses for flower color under field conditions. Developme...
متن کاملGenetic Structure, Linkage Disequilibrium and Association Mapping of Verticillium Wilt Resistance in Elite Cotton (Gossypium hirsutum L.) Germplasm Population
Understanding the population structure and linkage disequilibrium in an association panel can effectively avoid spurious associations and improve the accuracy in association mapping. In this study, one hundred and fifty eight elite cotton (Gossypium hirsutum L.) germplasm from all over the world, which were genotyped with 212 whole genome-wide marker loci and phenotyped with an disease nursery ...
متن کاملA Third Case of Compensatory Recombination in Interspecific Hybrids of Gossypium.
HERE are now several cases reported in the literature in which the transfer a chromosomal segment from one species of Gossypium to another results in altered recombination frequency in the chromosome to which the “foreign” segment has been transferred (SILOW 1944; RHYNE 1958; PHILLIPS 1961; STEPHENS 1961). Further, it is known that the altered recombination may take the form of either increased...
