Z. P. Lei, He, D. H., Xing, H. Y., Tang, B. S., Lu, B. X., Lei, Z. P., He, D. H., Xing, H. Y., Tang, B. S., and Lu, B. X., Genome-wide comparison of AP2/ERF superfamily genes between Gossypium arboreum and G. raimondii, vol. 15, p. -, 2016.

The APETALA2/ethylene response factor (AP2/ERF) transcription factor superfamily is known to regulate diverse processes of plant development and stress responses. We conducted a genome-wide analysis of the AP2/ERF gene in Gossypium arboreum and G. raimondii. Using RPSBLAST and HMMsearch, a total of 271 and 269 AP2/ERF genes were identified in the G. arboreum and G. raimondii genomes, respectively. A phylogenetic analysis classified diploid Gossypium spp AP2/ERF genes into 4 families and 16 subfamilies.

Introgression of cotton leaf curl virus-resistant genes from Asiatic cotton (Gossypium arboreum) into upland cotton (G. hirsutum)

S. Ahmad, Mahmood, K., Hanif, M., Nazeer, W., Malik, W., Qayyum, A., Hanif, K., Mahmood, A., and Islam, N., Introgression of cotton leaf curl virus-resistant genes from Asiatic cotton (Gossypium arboreum) into upland cotton (G. hirsutum), vol. 10, pp. 2404-2414, 2011.

Cotton is under the constant threat of leaf curl virus, which is a major constraint for successful production of cotton in the Pakistan. A total of 3338 cotton genotypes belonging to different research stations were screened, but none were found to be resistant against the Burewala strain of cotton leaf curl virus (CLCuV). We explored the possibility of transferring virus-resistant genes from Gossypium arboreum (2n = 26) into G. hirsutum (2n = 52) through conventional breeding techniques.
