To meet the growing demand for wood and pulp products, Eucalyptus plantations have expanded rapidly during the past two decades, becoming an integral part of the southern China landscape. Leaf blight caused by various Calonectria spp., is a serious threat to these plantations. In order to explore the diversity and distribution of Calonectria spp. in FuJian Province soils, samples were collected in Eucalyptus plantations and adjacent plantings of Cunninghamia lanceolata, Phyllostachys heterocycle and Pinus massoniana as well as in natural forests. Three hundred and fifty-three Calonectria isolates were recovered from soil samples and they were identified based on a comparison of multilocus DNA sequence data for the act (actin), cmdA (calmodulin), his3 (histone H3), rpb2 (the second largest subunit of RNA polymerase), tef1 (translation elongation factor 1-alpha) and tub2 (β-tubulin) gene regions, as well as morphological characteristics. Six known taxa including Calonectria aconidialis, Ca. hongkongensis, Ca. ilicicola, Ca. kyotensis, Ca. pacifica, Ca. pseudoreteaudii and one novel species described here as Ca. minensis sp. nov. were identified. Of these, Ca. aconidialis and Ca. kyotensis were the most prevalent species, and found in eight and seven sites, and four and five forest types, respectively. Calonectria spp. were most abundant in soils from Eucalyptus stands, followed by P. heterocycle and natural forests. Relatively few species were found in the soils associated with Cunninghamia lanceolata and Pinus massoniana. The abundance of known Calonectria spp. suggests that these fungi have been relatively well sampled in FuJian. The results are also consistent with the fact that most Calonectria diseases are found on Angiosperm as opposed to Gymnosperm plants.

Cytochrome P450 sterol 14α-demethylase (CYP51) is a key enzyme involved in the sterol biosynthesis pathway and serves as a target for sterol demethylation inhibitors (DMIs). In this study, the 3D structures of three CPY51 paralogues from Calonectria ilicicola (C. ilicicola) were first modeled by AlphaFold2, and molecular docking results showed that CiCYP51A, CiCYP51B, or CiCYP51C proteins individually possessed two active pockets that interacted with DMIs. Our results showed that the three paralogues play important roles in development, pathogenicity, and sensitivity to DMI fungicides. Specifically, CiCYP51A primarily contributed to cell wall integrity maintenance and tolerance to abiotic stresses, and CiCYP51B was implicated in sexual reproduction and virulence, while CiCYP51C exerted negative regulatory effects on sterol 14α-demethylase activity within the ergosterol biosynthetic pathway, revealing its genus-specific function in C. ilicicola. These findings provide valuable insights into developing rational strategies for controlling soybean red crown rot caused by C. ilicicola.

“…Calonectria ilicicola is a soil-borne fungal pathogen of global importance, which was first recorded in Georgia, the USA in 1965 and has since spread throughout peanut production areas in the southeastern United States (Bell and Sobers 1966;Wright et al 2010). CBR was first recorded on peanut in several counties in Guangdong Province in southern China in 2008, and subsequently observed on peanut in Jiangxi and Fujian Provinces, China, from 2010 to 2012 (Pan et al 2009(Pan et al , 2012Gai et al 2012). RCR was first recorded on soybean in Boluo County, Guangdong Province, China, and subsequently reported on soybean in Tonglu County, Zhejiang Province in eastern China in 2015 (Guan et al 2010;Gao et al 2012;Gai et al 2016).…”

The mitochondrial genomes have the potential to be 'molecular clock' due to its high mutation rate and low DNA recombination rate. Here, we sequenced the complete mitochondrial genome of three strains of Calonectria ilicicola (anamorph Cylindrocladium parasiticum) isolated from diseased peanut showing symptoms of Cylindrocladium black rot (CBR) and two C. ilicicola strains isolated from diseased soybean showing symptoms of Red crown rot (RCR). The complete mitogenome of C. ilicicola ranged from 41,187 bp to 64,421 bp in length, 22-34 protein-coding genes, 19-20 tRNA genes, 2 rRNA genes, and a control region. Besides, we used a phylogenomic approach to infer evolutionary relationships among 591 mitochondrial genomes that span the diversity of 294 fungal species, including C. ilicicola. Our results underline the potential importance of mitochondrial genomes in comparative genomic analyses and provide a robust evolutionary insight across the tree of life.
