Plant beta-1, 3-glucanases are pathogenesis-related proteins, which are implicated in plant defense responses against pathogen infection. Two genomic clones, FaBG2-1 and FaBG2-2, and a cDNA clone, FaBG2-3, encoding three different beta-1, 3-glucanases, are found in strawberry plants. In this book, the expression of FaBG2-1 and FaBG2-3 in strawberry plants infected with Colletotrichum fragariae and Colletotrichum acutatum--two important strawberry fungal pathogens--are examined. High levels of induction of both genes were observed in plants infected with C. fragariae, whereas lower levels of induction were observed in plants infected with C. acutatum. The expression of FaBG2-3 was much greater than FaBG2-1 in both the uninfected and the infected plants. The expressions of FaBG2-1 and FaBG2-3 in leaves, crowns, and roots were also examined at different time points during a 7 month growth period. Different organs showed different expression patterns for the two genes. This research shows that beta-1, 3-glucanase in strawberry plant may play an important roles in plant defense and development.
