“…Fov has been classified into at least eight races based on their pathogenicity against a panel of cotton germplasm, and by polymorphisms in certain house-keeping genes (Cianchetta et al, 2015;Sanogo & Zhang, 2016). Fov race 1 (Fov1) has been observed to be associated with root-knot nematode infections in the field, whereas race 4 (Fov4) is a highly virulent isolate that does not require rootknot nematode to cause significant diseases (Kim et al, 2005;Halpern et al, 2017;Wang et al 2018). Although the molecular mechanisms of Fov infections in cotton remain largely elusive, information about Fusarium wilt in other plant species may provide some insights into Fov-cotton interactions.…”

Summary Fusarium wilt caused by the ascomycete fungus Fusarium oxysporum is a devastating disease of many economically important crops. The mechanisms underlying plant responses to F. oxysporum infections remain largely unknown. We demonstrate here that a water‐soluble, heat‐resistant and nonproteinaceous F. oxysporum cell wall extract (FoCWE) component from multiple F. oxysporum isolates functions as a race‐nonspecific elicitor, also termed pathogen‐associated molecular pattern (PAMP). FoCWE triggers several demonstrated immune responses, including mitogen‐activated protein (MAP) kinase phosphorylation, reactive oxygen species (ROS) burst, ethylene production, and stomatal closure, in cotton and Arabidopsis. Pretreated FoCWE protects cotton seeds against infections by virulent F. oxysporum f. sp. vasinfectum (Fov), and Arabidopsis plants against the virulent bacterium, Pseudomonas syringae, suggesting the potential application of FoCWEs in crop protection. Host‐mediated responses to FoCWE do not appear to require LYKs/CERK1, BAK1 or SOBIR1, which are commonly involved in PAMP perception and/or signalling. However, FoCWE responses and Fusarium resistance in cotton partially require two receptor‐like proteins, GhRLP20 and GhRLP31. Transcriptome analysis suggests that FoCWE preferentially activates cell wall‐mediated defence, and Fov has evolved virulence mechanisms to suppress FoCWE‐induced defence. These findings suggest that FoCWE is a classical PAMP that is potentially recognised by a novel pattern‐recognition receptor to regulate cotton resistance to Fusarium infections.

“…In the last 15 yr, the yield loss in California caused by FOV race 4 (FOV4) has increased (Hutmacher et al., ) since it was first reported in the state in 2001 (Holmes et al., ; Kim et al., ). This race has been spread eastward to other western and southwestern cotton states, including far‐western Texas (El Paso County), based on field scouting followed by molecular confirmation (Halpern et al., ).…”

The New Mexico Agricultural Experiment Station announces the release of a glandless ‘NuMex COT 17 GLS’ cotton (Gossypium hirsutum L.) (Reg. no. CV‐141, PI 691837), which carries the incomplete dominant glandless allele Gl2e. NuMex COT 17 GLS was derived from an advanced backcross progeny of a cross between the Gl2e allele donor ‘Bahtim 110’ (G. barbadense L.) and glanded upland cotton ‘CRI 12’, followed by five backcrosses with glanded upland ‘CRI 35’ as the recurrent parent. It is resistant to Fusarium wilt (FW) race 4, with a level of resistance similar to the resistant checks ‘PHY 802RF’ and ‘PHY 811RF’, when evaluated in two naturally infected fields in California, and it is more resistant than ‘Acala 1517‐08’ when evaluated in the greenhouse in New Mexico. This new cultivar was tested in seven replicated field trials in New Mexico in 2013–2017 and in 11 tests across nine states in 2014. Compared with glandless ‘Acala GLS’, ‘Acala 1517‐18 GLS’, and ‘NuMex COT 15 GLS’, NuMex COT 17 GLS yielded 26, 16, and 13% more lint, respectively, and produced 93% of glanded Acala 1517‐08 yield. It had significantly higher lint percentage than all the check cultivars. It is classified as a medium staple with fiber quality inferior to long‐staple Acala cotton cultivars. NuMex COT 17 GLS is especially adapted to the Mississippi Delta and was the top yielder in the region. It is resistant to four races of bacterial blight and less susceptible to Alternaria leaf spot than Acala 1517‐08. The release of NuMex COT 17 GLS represents one of the first successful introgressions from G. barbadense germplasm with FW race 4 resistance.

“…In the United States, races 1, 2, 3, 4, and 8 were identified (Cianchetta et al., ; Holmes, Bennett, Spurgeon, Colyer, & Davis, ; Kim, Hutmacher, & Davis, ). Race 4 (FOV4) was originally identified in India and has become a major threat to US cotton production (Halpern et al., ; Hutmacher et al., ; Zhu et al., ) since it was first reported in California in 2001 (Holmes et al., ; Kim et al., ). Other races are recognized in other cotton‐producing countries, including race 3 in Egypt and Israel, race 5 in Sudan, race 6 in Brazil, and races 7 and 8 in China (Hillocks, ; Sanogo & Zhang, ).…”

The New Mexico Agricultural Experiment Station announces the release of an upland cotton (Gossypium hirsutum L.) cultivar ‘Acala 1517‐20’ (Reg. no. CV‐142, PI 691836). Acala 1517‐20 was derived from a single plant selection in a biparental cross between an unreleased upland line NM 010368 and a Chinese cultivar ‘Jimian 958’ that is resistant to Fusarium wilt (Fusarium oxysporum f. sp. vasinfectum, FOV) race 7. Acala 1517‐20 is moderately resistant to FOV race 4 (FOV4), similar to ‘Pima DP 358 RF’, based on vascular root staining and growth vigor in the field in California and foliar disease severity ratings in the greenhouse in New Mexico. This new cultivar was tested in nine replicated field trials in New Mexico in 2008–2017 and in 20 tests in 14 locations across 12 states in 2016–2017. Acala 1517‐20 yielded similarly to the high‐yielding Acala cotton cultivars, including ‘Acala 1517‐99W’, ‘Acala 1517‐16 B2RF’, and ‘Acala 1517‐08’, and the Acala‐type transgenic commercial cultivars, including ‘PHY 725 RF’, ‘PHY 755 WRF’, ‘PHY 764 WRF’, and ‘FM 2322 GL’, but yielded lower than ‘FM 1830 GLT’. Compared with Acala 1517‐08, Acala 1517‐20 had higher lint percentage, lower boll and seed weight, and lower short fiber content. Acala 1517‐20 was susceptible to four races of bacterial blight and Alternaria leaf spot. It is recommended for regions where Acala cotton is grown in the presence of FOV4. It will also provide a new source of resistance to FOV4.
