Transcriptome Analysis Reveals Candidate Genes Associated with Leaf Etiolation of a Cytoplasmic Male Sterility Line in Chinese Cabbage (Brassica Rapa L. ssp. Pekinensis). Int J Mol Sci 2018; 19:E922.

Abstract
Cytoplasmic male sterility (CMS) is universally utilized in cruciferous vegetables. However, the Chinese cabbage hau CMS lines, obtained by interspecific hybridization and multiple backcrosses of the Brassica juncea (B. juncea) CMS line and Chinese cabbage, show obvious leaf etiolation, and the molecular mechanism of etiolation remains elusive. Here, the ultrastructural and phenotypic features of leaves from the Chinese cabbage CMS line 1409A and maintainer line 1409B are analyzed. The results show that chloroplasts of 1409A exhibit abnormal morphology and distribution. Next, RNA-sequencing (RNA-Seq) is used to identify 485 differentially expressed genes (DEGs) between 1409A and 1409B, and 189 up-regulated genes and 296 down-regulated genes are found. Genes that affect chloroplasts development, such as GLK1 and GLK2, and chlorophyll biosynthesis, such as PORB, are included in the down-regulated DEGs. Quantitative real-time PCR (qRT-PCR) analysis validate that the expression levels of these genes are significantly lower in 1409A than in 1409B. Taken together, these results demonstrate that leaf etiolation is markedly affected by chloroplast development and pigment biosynthesis. This study provides an effective foundation for research on the molecular mechanisms of leaf etiolation of the hau CMS line in Chinese cabbage (Brassica rapa L. ssp. pekinensis).

Abstract
Colletotrichum higginsianum is a widely distributed fungus attacking many cruciferous species. To investigate pathogenic mechanisms of the pathogen on the host Arabidopsis thaliana, we screened and obtained a virulence-deficient mutant Ch-1-T513 in a T-DNA insertion mutant library of C. higginsianum. The mutant Ch-1-T513 produced yellow colony centers with distorted multi-branching hyphal tips as well as producing few conidia. Heavily swollen hyphae in the mutant could be observed, and intra-hyphal hyphae were found to be formed in the balloon-shaped hyphae. The mutant failed to produce lesions on 12-day-old Arabidopsis seedlings, and invasive hyphae did not differentiate into large primary and thin secondary hyphae after appressorial formation on Arabidopsis leaves, but formed abundant bulbous hyphae in epidermal cells. Southern blot analysis showed Ch-1-T513 had double-site T-DNA integrations. The mutant had insertions upstream of genes for a major facilitator superfamily (MFS) transporter, ChMfs1 and an aldo/keto reductase, ChAkr. Complementation experiments by transforming genomic sequences from a wild-type strain into the insertion mutant demonstrated that ChMfs1 is involved in the Ch-1-T513 phenotype. The complementation strain C-ChMfs1-1 exhibited normal hyphal morphology, conidiation, and pathogenicity identical to the wild-type. The results demonstrate that ChMfs1 is involved in intra-hyphal hyphae production, conidiation, and pathogenicity in C. higginsianum. To our knowledge, this is the first report of a MFS transporter gene in a phytopathogenic fungus associated with intra-hyphal hyphae formation, playing a key role in infection of its plant host.

Abstract
A novel species of Botrytis from Sedum sarmentosum was described based on morphology and analyses of DNA sequences of nuc rDNA ITS regions and three nuclear genes (G3PDH, HSP60, RPB2). Meanwhile pathogenicity in 32 plant species, response to temperature for growth and conidial germination for the species were determined. The Botrytis species was named Botrytis pyriformis sp. nov. It was characterized by formation of grayish mycelia, brownish conidia and melanized sclerotia on PDA. The conidia are pear-shaped, melanized and covered with abundant villiform appendages on the conidial surface. Comparison of the ITS sequences confirmed its placement in the genus Botrytis Phylogenetic analysis based on DNA sequences of G3PDH, HSP60 and RPB2 genes indicated that B. pyriformis and other 30 Botrytis species form a monophyletic clade, which was further divided into three subclades. Subclade I comprised B. pyriformis alone, whereas subclades II and III comprised six and 24 Botrytis species, respectively. Botrytis pyriformis could not infect 32 plant species including S. sarmentosum, possibly due to deficiency in formation of infection cushions. This study presents a formal description and illustrations for B. pyriformis and provides experimental evidence, indicating that B. pyriformis might be a saprophytic species.

Abstract
Sclerotinia sclerotiorum is a notorious plant fungal pathogen with a broad host range including many important crops, such as oilseed rape, soybean, and numerous vegetable crops. Hypovirulence-associated mycoviruses have attracted much attention because of their potential as biological control agents for combating plant fungal diseases and for use in fundamental studies on fungal pathogenicity and other properties. This chapter describes several mycoviruses that were isolated from hypovirulent strains except for strain Sunf-M, which has a normal phenotype. These viruses include the geminivirus-like mycovirus Sclerotinia sclerotiorum hypovirulence-associated DNA virus 1 (SsHADV-1), Sclerotinia debilitation-associated RNA virus (SsDRV), Sclerotinia sclerotiorum RNA virus L (SsRV-L), Sclerotinia sclerotiorum hypovirus 1 (SsHV-1), Sclerotinia sclerotiorum mitoviruses 1 and 2 (SsMV-1, SsMV-2), and Sclerotinia sclerotiorum partitivirus S (SsPV-S). Unlike many other fungi, incidences of mixed infections with two or more mycoviruses in S. sclerotiorum are particularly high and very common. The interaction between SsDRV and S. sclerotiorum is likely to be unique. The significance of these mycoviruses to fungal ecology and viral evolution and the potential for biological control of Sclerotinia diseases using mycoviruses are discussed.
