Effects of Colchicine Treatments on Chromosome Doubling in Three Diploid Cotton Species
Mustafa, Nada S.; Liu, Fang; Magwanga, Richard; Wang, Xingxing; Cai, Xiaoyan; Zhang, Zhenmei; Wang, Kunbo (Journal of Multidisciplinary Engineering Science and Technology, 2017-04-04)Colchicine has been used to induce chromosome doubling in plant species. Diploid cotton species have inherited desirable genes that are resistant to biotic and abiotic stresses and also possesses useful fiber quality traits, ... -
GBS Mapping and Analysis of Genes Conserved between Gossypium tomentosum and Gossypium hirsutum Cotton Cultivars that Respond to Drought Stress at the Seedling Stage of the BC2F2 Generation
Magwanga, Richard; Lu, Pu; Kirungu, Joy; Diouf, Latyr; Dong, Qi; Hu, Yangguang; Cai, Xiaoyan; Xu, Yanchao; Hou; Zhou, Zhongli; Wang, Xingxing; Wang, Kunbo; Liu, Fang (Multidisciplinary Digital Publishing Institute, 2018-05-30)Cotton production is on the decline due to ever-changing environmental conditions. Drought and salinity stress contribute to over 30% of total loss in cotton production, the situation has worsened more due to the narrow ... -
High-Density Linkage Map Construction and Mapping of Salt-Tolerant QTLs at Seedling Stage in Upland Cotton Using Genotyping by Sequencing (GBS)
Diouf, Latyr; Pan, Zhaoe; He, Shou-Pu; Gong, Wen-Fang; Jia, Yin Hua; Magwanga, Richard; Romy, Kimbembe Romesh Eric; Harun or Rashid; Kirungu, Joy; Du, Xiongming (Multidisciplinary Digital Publishing Institute, 2017-11-05)Over 6% of agricultural land is affected by salinity. It is becoming obligatory to use saline soils, so growing salt-tolerant plants is a priority. To gain an understanding of the genetic basis of upland cotton tolerance ... -
Knockdown of Ghalba_4 and Ghalba_5 Proteins in Cotton Inhibits Root Growth and Increases Sensitivity to Drought and Salt Stresses
Magwanga, Richard; Kirungu, Joy Nyangasi; Lu, Pu; Cai, Xiaoyan; Xu, Yanchao; Wang, Xingxing; Zhou, Zhongli; Hou, Yuqing; Agong, Stephen Gaya; Wang, Kunbo; Liu, Fang (Frontiers, 2019-10-15)We found 33, 17, and 20 Alba genes in Gossypium hirsutum, Gossypium arboretum, and Gossypium raimondii, respectively. The Alba protein lengths ranged from 62 to 312 aa, the molecular weight (MW) from 7.003 to 34.55 kDa, ... -
Qtl Mapping for Salt Tolerance in an Intra-Specific Upland Cotton at Seedling Stage Using Ssr Markers
Diouf, Latyr; Pan, Zhaoe; He, Shou-Pu; Gong, Wen-Fang; Magwanga, Richard; Du, Xiongming (ESci Journals, 2017)Cotton is a moderately salt-tolerant crop, but its salt tolerance threshold is not more than 7.7 ds•m−1. The seedling stage of cotton is the highly sensitive to salinity and the effects can be quantified by measuring ... -
Simple Sequence Repeat (SSR) Genetic Linkage Map of D Genome Diploid Cotton Derived from an Interspecific Cross between Gossypium davidsonii and Gossypium klotzschianum
Kirungu, Joy; Deng, Yanfeng; Cai, Xiaoyan; Magwanga, Richard; Zhou, Zhongli; Wang, Xingxing; Wang, Yuhong; Zhang, Zhenmei; Wang, Kunbo; Liu, Fang (Multidisciplinary Digital Publishing Institute, 2018-01-11)The challenge in tetraploid cotton cultivars is the narrow genetic base and therefore, the bottleneck is how to obtain interspecific hybrids and introduce the germplasm directly from wild cotton to elite cultivars. ...
