Identification of endogenous gibberellins in strawberry, including the novel gibberellins GA123, GA124 and GA125.

abstract：:Phytoalexins are inducible chemical defenses produced by plants in response to diverse forms of stress, including microbial attack. Our search for phytoalexins from cruciferous plants resistant to economically important fungal diseases led us to examine stinkweed or pennycress (Thlaspi arvense), a potential source of ...
