“…During this same amount of time in 2019, the crop received nearly three centimeters more rain (13.0 cm), and only 350 DD60’s had accumulated. This difference in environmental conditions between the two seasons could have significantly affected the disease pressure throughout the year as has been observed with Fusarium wilt affecting many crops around the world ( Scott et al., 2010 ; Li et al., 2017 ; Jelínek et al., 2019 ).

This study assess the population diversity and temporal variability of caused by Fusarium oxysporum f. sp. vasinfectum (FOV) races/genotypes infecting cotton cultivars with either FOV or Meloidogyne incognita resistance. All plants sampled demonstrated typical symptoms of FOV including wilting, chlorosis and necrosis of the leaves, and discoloration of the vascular tissue in the stem. A diverse population of FOV was characterized. Eight races/genotypes of FOV were collected throughout the three site years. FOV race 1 was the most predominant in all tests (AUDPC=101.1); statistically higher numbers of isolates from LA-108 (AUDPC=59.9), race 8 (AUDPC=47.5), and race 2 (AUDPC=38.6) were also found compared to other races and genotypes collected. FOV race 1, race 2, race 8, and 108 were the most virulent races identified. The genotypes MDS-12, LA-110, and LA-127/140 were found in all tests but at a low incidence, and LA-112 was only found in trace amounts. MDS-12, LA-110, LA-112, and LA-127/140 produced less disease pressure. FOV race 4 which is highly virulent and present in California and Texas was not found in Alabama. A positive correlation was observed between the accumulation of growing degree days and FOV race 1, race 2, race 8, LA-108, and LA-110. Later symptom expression influenced by seasonal heat partially mitigates damage allowing cotton to produce bolls though they may be reduced in number and lint quality. Plant resistance to the FOV as expressed in these cultivars appears to provide better protection than M. incognita resistance. PhytoGen 72, which is resistant to FOV races/genotypes had low levels of FOV infection even though it sustained a high level of M. incognita root population density. The M. incognita resistant cultivars Deltapine 1558NR B2RF and PhytoGen 480 W3FE supported a lower nematode population density, however, FOV disease incidence was not reduced. FOV races/genotypes did not vary significantly between the nematode resistant and nematode susceptible cultivars.

“…There are multiple examples of diseases caused by F. oxysporum formae speciales in which disease severity in susceptible varieties increases as temperatures increase from 22 to 28°C (e.g., f. sp. ciceris in chickpea, cepae in onions, conglutinans in cole crops, lactucae in lettuce, lycopersici in tomatoes, medicaginis in alfalfa, and melonis in melons; Bosland et al, 1988 ; Navas-Cortés et al, 2007 ; Scott et al, 2010 ; Jelínek et al, 2019 ).

Currently, Fusarium oxysporum f. sp. apii (Foa) race 4 in celery and F. oxysporum f. sp. coriandrii (Foci) in coriander have the characteristics of emerging infectious plant diseases in coastal southern California: the pathogens are spreading, yield losses can be severe, and there are currently no economical solutions for their control. Celery, and possibly coriander, production in these regions is are likely to have more severe disease from projected warmer conditions in the historically cool, coastal regions. Experimental evidence shows that Foa race 4 causes much higher disease severity when temperatures exceed 21°C. A phylogenomic analysis indicated that Foa race 4, an older, less virulent, and uncommon Foa race 3, and two Foci are closely related in their conserved genomes. These closely related genotypes are somatically compatible. Foa race 4 can also cause disease in coriander and the two organisms readily form “hetero” conidial anastomosis tubes (CAT), further increasing the likelihood of parasexual recombination and the generation of novel pathotypes. A horizontal chromosome transfer event likely accounts for the difference in host range between Foci versus Foa races 4 and 3 because they differ primarily in one or two accessory chromosomes. How Foa race 4 evolved its hyper-virulence is unknown. Although the accessory chromosomes of Foa races 3 and 4 are highly similar, there is no evidence that Foa race 4 evolved directly from race 3, and races 3 and 4 probably only have a common ancestor. Foa race 2, which is in a different clade within the Fusarium oxysporum species complex (FOSC) than the other Foa, did not contribute to the evolution of race 4, and does not form CATs with Foa race 4; consequently, while inter-isolate CAT formation is genetically less restrictive than somatic compatibility, it might be more restricted between FOSC clades than currently known. Other relatively new F. oxysporum in coastal California include F. oxysporum f. sp. fragariae on strawberry (Fof). Curiously, Fof “yellows-fragariae” isolates also have similar core genomes to Foa races 4 and 3 and Foci, perhaps suggesting that there may be core genome factors in this lineage that favor establishment in these soils.
