Among eleven putative varieties, widely known varieties was F

affmune, that features 37 strains and you can symbolizing 31.6% of overall sample. This is sequentially with F. aff. cugenangense (34 isolates, 30.1%), a keen undescribed book types Fusarium aff. sp. (thirteen isolates, 11.1%), F. aff. gossyypinum (11 isolates, nine.4%), F. aff. fujikuroi (10 isolates, 8.5%), F. aff. nirenbergiae (eight isolates, 6%), and another isolate per (0.85%) regarding F. aff. solani, F. aff. verticillioides, F. aff. asiaticum, F. aff. curvatum, and you may F. aff. odoratissimum. Of them eleven putative species, the second six belonged towards FOSC: F. aff. cugenangense, F. aff. curvatum, F. aff. gossyypinum, F. aff. nirenbergiae, F. aff. odoratissimum, and you will Fusarium aff.sp, accounting to have 57.3% ( isolates) of one’s complete Fusarium population. Complete, our overall performance reveal that FOSC and you will F. affmune will be prominent species complex/types causing Fusarium yam wilt on these half dozen geographical places (Tables step 3, 4).

Diversity and you may Shipping away from Fusarium Species

Dining table 4 sumong the newest six geographic nations. The Fusarium kinds richness and you can Simpson’s variety assortment directory for various web sites within this each one of the half a dozen regions in Jiangxi and you can Hunan provinces have been displayed within the Dining tables 1, 4. Within each of the half dozen places, no less than three putative Fusarium kinds were remote. Particularly, one or two geographic products (Ganzhou and you can Fuzhou) contained about three putative Fusarium species for each; two (Yiyang and you may Yichun) contains five putative Fusarium variety for every single, one to (Ruichang) had four putative Fusarium species, and something (Ji’an) had seven putative Fusarium kinds. Even though varieties richness among the many countries varied because of the several folds, the new assortment indicator was basically very similar, the more than 0.52. The highest variety diversity are utilized in Ruichang (0.73), accompanied by Ji’an (0.70), Yichun (0.69), Ganzhou (0.57), Fuzhou (0.56), and you can Yiyang (0.52) (Table cuatro).

At the personal bush top, we successfully isolated Fusarium stresses from 37 of one’s 52 infected yam vegetation. Of those 37 plant life, three were found to be infected by about three or more putative types of Fusarium, 15 was seen to be infected from the several putative types of Fusarium (Dining table 3) since remaining 19 was discovered to be infected of the one putative varieties for each and every. Ones 19 unhealthy plant life infected by just one putative Fusarium types, 7 was contaminated by the F. aff. cugenangense, half a dozen because of the F. affmune, a couple of the F. aff. fujikuroi, plus the most other three was in fact contaminated by F. aff. gossypinum, F. aff. nirenbergiae, and you will Fusarium aff.sp., respectively (Desk step 3).

Additionally, with the Chi-rectangular backup desk attempt, considering the seemingly short test sizes from private kinds and this new intimate relationships of the half dozen variety in this FOSC, we handled FOSC in general taxonomic category in this decide to try

We after that determined if the other Fusarium variety was marketed differently one of many geographical nations. Here, precisely the following the four geographic nations that have try systems greater than fifteen were utilized having pairwise reviews: Ruichang, Yichun, Ji’an, and you will Yiyang. Making use of their small decide to try designs, the remaining a couple geographical products (Ganzhou and you will Fuzhou) just weren’t included in the analyses. Our analyses revealed that the newest Yichun populace had a notably more Fusarium varieties constitution off their three regions (Chi-rectangular beliefs every >9.5, df = 2, p 0.1). Particularly, in the Yichun, the best kinds try F. affmune (40%), with F. aff. fujikuroi (33.3%), that have Fusarium aff. sp. (16.7%) and you will F. aff. cugenangense (10.0%) as being the 3rd and you may 4th preferred kinds. Interestingly, F. aff. fujikuroi was only used in Yichun. From inside the around three of the left four countries (Ruichang, Fuzhou, and you can Yiyang), the most famous varieties was F. aff. cugenangense, with F. affmune. In Ji’an, the most common variety was F. aff. gossypinum, followed by F. affmune (Desk cuatro). At present, the fresh new sample size out-of Ganzhou is too quick to draw one important achievement concerning the frequency away from private Fusarium kinds as well as in the fresh contrasting together with other places in the Fusarium varieties composition.
