Constitutive overexpression of a ripening-related pepper endo-1,4-beta-glucanase in transgenic tomato fruit does not increase xyloglucan depolymerization or fruit softening.

Abstract excerpt

The ripening-related pepper endo-1,4-beta-D-glucanase (EGase) CaCel1 was over-expressed in transgenic tomato plants under the control of the constitutive 35S promoter to investigate the effects on plant growth and fruit softening of high levels of a potential cell wall-degrading activity. In transgenic fruit, recombinant CaCel1 protein was associated with a high-salt putative cell wall fraction, and extractable...
