  • Recent Progress in Enhancing Fungal Disease Resistance in Ornamental Plants
    International Journal of Molecular Sciences Review Recent Progress in Enhancing Fungal Disease Resistance in Ornamental Plants Manjulatha Mekapogu 1, Jae-A Jung 1,* , Oh-Keun Kwon 1, Myung-Suk Ahn 1, Hyun-Young Song 1 and Seonghoe Jang 2,* 1 Floriculture Research Division, National Institute of Horticultural and Herbal Science, Rural Development Administration, Wanju 55365, Korea; [email protected] (M.M.); [email protected] (O.-K.K.); [email protected] (M.-S.A.); [email protected] (H.-Y.S.) 2 World Vegetable Center Korea Office (WKO), Wanju 55365, Korea * Correspondence: [email protected] (J.-A.J.); [email protected] (S.J.) Abstract: Fungal diseases pose a major threat to ornamental plants, with an increasing percentage of pathogen-driven host losses. In ornamental plants, management of the majority of fungal diseases primarily depends upon chemical control methods that are often non-specific. Host basal resistance, which is deficient in many ornamental plants, plays a key role in combating diseases. Despite their economic importance, conventional and molecular breeding approaches in ornamental plants to facilitate disease resistance are lagging, and this is predominantly due to their complex genomes, limited availability of gene pools, and degree of heterozygosity. Although genetic engineering in ornamental plants offers feasible methods to overcome the intrinsic barriers of classical breeding, achievements have mainly been reported only in regard to the modification of floral attributes in ornamentals. The unavailability of transformation protocols and candidate gene resources for several ornamental crops presents an obstacle for tackling the functional studies on disease resistance. Re- cently, multiomics technologies, in combination with genome editing tools, have provided shortcuts Citation: Mekapogu, M.; Jung, J.-A.; to examine the molecular and genetic regulatory mechanisms underlying fungal disease resistance, Kwon, O.-K.; Ahn, M.-S.; Song, H.-Y.; Jang, S.

Both species co-occur in European orchards although M. fructicola is considered to cause the most severe yield losses in stone fruit. This study aimed to generate a high-quality genome of M. fructicola and to exploit it to identify genes that may contribute to pathogen virulence. PacBio sequencing technology was used to assemble the genome of M. fructicola. Manual structural curation of gene models, supported by RNA-Seq, and functional annotation of the proteome yielded 10,086 trustworthy gene models. The genome was examined for the presence of genes that encode secreted proteins and more specifically effector proteins. A set of 134 putative effectors was defined. Several effector genes were cloned into Agrobacterium tumefaciens for transient expression in Nicotiana benthamiana plants, and some of them triggered necrotic lesions. Studying effectors and their biological properties will help to better understand the Citation: Vilanova, L.; interaction between M.
