Host defense peptides (HDPs) are components of plant defensive barriers that resist microbial infection. Members of the Snakin/GASA protein family in plants have functions of regulating plant growth, defense, and bacteriostasis. Most mangrove plants grow in coastal zones. In order to survive in harsh environments, mangrove plants have evolved complex adaptations against microbes. In this study, Snakin/GASA family members were identified and analyzed in the genomes of three mangrove species. Twenty-seven, thirteen, and nine candidate Snakin/GASA family members were found in Avicennia marina, Kandelia obovata, and Aegiceras corniculatum, respectively. These Snakin/GASA family members were identified and categorized into three subfamilies via phylogenetic analysis. The genes coding for the Snakin/GASA family members were unevenly distributed on chromosomes. Collinearity and conservative motif analyses showed that the Snakin/GASA family members in K. obovata and A. corniculatum underwent multiple gene duplication events. Snakin/GASA family member expression in normal leaves and leaves infected with pathogenic microorganisms of the three mangrove species was verified using real-time quantitative polymerase chain reaction. The expression of KoGASA3 and 4, AcGASA5 and 10, and AmGASA1, 4, 5, 15, 18, and 23 increased after microbial infection. This study provides a research basis for the verification of HDPs from mangrove plants and suggests directions for the development and utilization of marine biological antimicrobial peptides.

Chinese fir (Cunninghamia lanceolata) is a special fast-growing commercial tree species in China with high economic value. In recent years, leaf blight disease on C. lanceolata has been observed frequently. The diversity of Fusarium species associated with leaf blight on C. lanceolata in China (Fujian, Guangxi, Guizhou, and Hunan provinces) was evaluated using morphological study and molecular multi-locus analyses based on RNA polymerase second largest subunit (RPB2), translation elongation factor 1-alpha (TEF-1α), and RNA polymerase largest subunit (RPB1) genes/region as well as the pairwise homoplasy index tests. A total of five Fusarium species belonging to four Fusarium species complexes were recognized in this study. Two known species including Fusarium concentricum and F. fujikuroi belonged to the F. fujikuroi species complex, and three new Fusarium species were described, i.e., F. fujianense belonged to the F. lateritium species complex, F. guizhouense belonged to the F. sambucinum species complex, and F. hunanense belonged to the F. solani species complex. To prove Koch’s postulates, pathogenicity tests on C. lanceolata revealed a wide variation in pathogenicity and aggressiveness among the species, of which F. hunanense HN33-8-2 caused the most severe symptoms and F. fujianense LC14 led to the least severe symptoms. To our knowledge, this study also represented the first report of F. concentricum, F. fujianense, F. fujikuroi, F. guizhouense, and F. hunanense causing leaf blight on C. lanceolata in China.
