Host Response to Reniform Nematode Infection in Resistant and Susceptible Gossypium arboreum Accessions
The reniform nematode (RN), Rotylenchulus reniformis Lindford and Oliveira, is a serious threat to cotton production. In fields infested with RN, yield losses are estimated at 0 to kg/ha (Robinson, 001). Genetic resistance to RN has not been reported for any commercial cultivar of cotton (Gossypium hirsutum L.) (Robinson et al., 00 ); however, it has been found in G. arboreum (Stewart and Robbi...
متن کاملIntrogression of resistance to reniform nematode (Rotylenchulus reniformis) into upland cotton (Gossypium hirsutum) from Gossypium arboreum and a G. hirsutum/Gossypium aridum bridging line
Gossypium hirsutum L. is the predominant cotton of commerce and all cultivars of this species are susceptible to the reniform nematode, Rotylenchulus reniformis. To introgress resistance to R. reniformis into the tetraploid 2(AD1) G. hirsutum, a resistant diploid A2-genome Gossypium arboreum accession (A2190) was crossed with a hexaploid 2((AD1)D4) bridging line (G 371) to obtain a tetraploid t...
متن کاملIntrogression of Reniform Nematode Resistance from G. arboreum to Upland Cotton: 2005 Advances
Accordingly to the Arkansas Nematode Diagnostic Clinic 00 (Cooperative Extension Service, 00 ) the reniform nematode (Rotylenchulus reniformis Lindford and oliveira) (RN) is present in twelve counties in the state where most of the cotton (G. hirsutum) is cultivated. In fields infested with RN, yield losses are estimated at 340 to kg/ha (Robinson, 001). The RN is expected to become an even grea...
متن کاملGenetic diversity and relationship analysis of Gossypium arboreum accessions.
Simple sequence repeat techniques were used to identify the genetic diversity of 101 Gossypium arboreum accessions collected from India, Vietnam, and the southwest of China (Guizhou, Guangxi, and Yunnan provinces). Twenty-six pairs of SSR primers produced a total of 103 polymorphic loci with an average of 3.96 polymorphic loci per primer. The average of the effective number of alleles, Nei's ge...
متن کاملTranscriptome Analysis of Cotton (Gossypium hirsutum L.) Genotypes That Are Susceptible, Resistant, and Hypersensitive to Reniform Nematode (Rotylenchulus reniformis)
Reniform nematode is a semi-endoparasitic nematode species causing significant yield loss in numerous crops, including cotton (Gossypium hirsutum L.). An RNA-sequencing analysis was conducted to measure transcript abundance in reniform nematode susceptible (DP90 & SG747), resistant (BARBREN-713), and hypersensitive (LONREN-1) genotypes of cotton (Gossypium hirsutum L.) with and without reniform...
