“…Cotton production globally is threatened by various biotic stress factors, the most common and with greater economic loss is the Verticillium dahliae infection [ 60 ]. V. dahliae infection, which is ranked top among the various forms of biotic stresses with higher economic losses in cotton production, because it causes Verticillium wilt, a terminal disease that results in plant death [ 7 ]. Controlling of the fungus that causes Verticillium wilt has posed a great challenge to plant breeders due to its wide host range, and its longevity in the soil in absence of suitable host [ 61 ].…”

“…Its growth and production has been hampered by fungus infection. It is estimated that the losses incurred due to disease infection is extremely high in major cotton growing regions, which is due to no remedy once the disease occurs [ 7 ]. Several attempts have been made to developed resistant cotton cultivars using resistant germplasm, such as Gossypium barbadense, also known as the Egyptian or pima cotton [ 8 ].…”

Verticillium wilt that is caused by Verticillium dahliae, does result in massive annual yield losses and fiber quality decline in cotton. Control by conventional mechanisms is not possible due to a wide host range and the longevity of dormant fungi in the soil in the case of absence of a suitable host. Plants have developed various mechanisms to boost their immunity against various diseases, and one is through the induction of various genes. In this research, we carried out RNA sequencing and then identified the members of the adenosine triphosphate (ATP)-binding cassette (ABC) proteins to be critical in enhancing resistance to V. dahliae infection. A total of 166 proteins that are encoded by the ABC genes were identified in Gossypium raimondii with varying physiochemical properties. A novel ABC gene, Gorai.007G244600 (ABCF5), was found to be highly upregulated, and its homolog in the tetraploid cotton Gh_D11G3432 (ABCF5), was then silenced through virus induced gene silencing (VIGS) in G. hirsutum, tetraploid upland cotton. The mutant cotton seedlings ability to tolerate V. dahliae infection was significantly reduced. Based on the evaluation of oxidant enzymes, hydrogen peroxide (H2O2) and malondialdehyde (MDA) showed significantly increased levels in the leaves of the mutant compared to the wild type. In addition, antioxidant enzymes, peroxidase (POD), catalase (CAT), and superoxide dismutase (SOD) concentrations were reduced in the mutant cotton leaves after treatment with V. dahliae fungi as compared to the wild type. Moreover, expression levels of the biotic stress genes, cotton polyamine oxidase (GhPAO), cotton ribosomal protein L18 (GhRPL18), and cotton polygalacturonase-inhibiting protein-1 (GhPGIP1), were all downregulated in the mutant but they were highly upregulated in the various tissues of the wild cotton seedlings. This research has shown that ABC genes could play an important role in enhancing the immunity of cotton to V. dahliae infection, and thus can be explored in developing more resilient cotton genotypes with improved resistance to V. dahliae infection in cotton.

“…Two commercial checks common across most tests were FiberMax brand 'FM 958 ′ (PVP 200100208) and FiberMax brand 'FM 989 ′ (PVP 009800259). FM 958 was recommended for production on the Texas High Plains, having appropriate maturity and boll type, whereas FM 989 was a commercial cultivar recommended for yield and fiber quality (Erdogan et al, 2006). The experimental lines used in these studies were selected from nurseries with various breeding objectives.…”

Increasing demands for irrigation and declining water availability are becoming critical issues in the Texas High Plains, the primary cotton (Gossypium hirsutum L.) growing area of the United States. Developing breeding lines suitable for water‐limited production is an important objective of the Texas A&M AgriLife Research cotton breeding program in Lubbock. CA 4007 cotton germplasm (Reg. no. GP‐1062, PI 691459) was derived from a 1993 cross of Verhalen V83‐116 with CA 2159, informal historical releases developed by cotton breeding programs at Oklahoma State University and Texas A&M AgriLife Research in Lubbock, respectively. Performance testing for yield, fiber quality, and other related agronomic properties was conducted in rainfed and irrigated conditions during the 2007, 2008, and 2009 growing seasons. Based on yield performance and other agronomic properties, CA 4007 was included in experiments to evaluate cotton genotypes’ response to moisture stress and its impact on yield, fiber quality, and other agronomic traits. Results indicate that CA 4007 germplasm developed from lines released in two southwestern United States public breeding programs produced good yield and fiber quality under water‐limited production across several growing seasons when compared to commercial production check cultivars in the Texas High Plains.

“…The authors of [9] reported that the combined effect of chlorosis, water stress, and stomatal closure could accelerate the reduction in photosynthesis rate of leaves that exhibited disease symptoms. Therefore, there is a substantial loss of lint yield and fiber quality associated with Verticillium wilt of cotton [10,11], which may be caused by the reduction in photosynthesis and increased resistance to hydraulic conductance in the xylem.…”

Verticillium wilt, caused by Verticillium dahliae Kleb., leads to significant losses in cotton yield and fiber quality worldwide. To investigate Verticillium wilt impact on photosynthesis rate, yield, and fiber quality, six upland cotton genotypes, namely Verticillium susceptible (DP 1612 B2XF) and partially resistant (FM 2484B2F) commercial cultivars and four breeding lines, were grown to maturity under greenhouse conditions in soil either infested or not infested with V. dahliae microsclerotia. Photosynthetic rate, lint, and seed yield were all higher (p < 0.05) for FM 2484B2F than DP 1612 B2XF when infected with V. dahliae. When comparing healthy (H) to Verticillium wilt (VW) affected plants, fiber properties were greatly impacted. Micronaire decreased from 5.0 (H) to 3.6 (VW) with DP 1612 B2XF and 4.4 (H) to 4.1 (VW) with FM 2484B2F. The maturity ratio decreased from 0.90 (H) to 0.83 (VW) for DP 1612 B2XF and was unchanged for FM 2484B2F (0.90). Fiber properties such as short fiber content, nep count, fineness, and immature fiber content were also significantly affected under Verticillium wilt pressure. With Verticillium wilt affected plants, lines 16-13-601V and 17-17-206V performed similarly to FM 2484B2F for photosynthetic rate, yield, and all fiber properties measured. When selecting for improved cultivars in the presence of Verticillium wilt, it is important to select for relatively unchanged fiber properties under disease pressure in addition to reduced disease severity and increased yield.
