Abstract

The purpose of this study was to assess the growth and development of chitinase transgenic peanuts against phytopathogenic fungi including lines WTA-2 containing the Chi42 gene, S1A-15 containing the syncodChi42-1 gene and S2A-12 containing the syncodChi42-2 gene. The present results show that the peanut lines containing two optimized genes derived from the Chi42 wild-type gene of Trichoderma asperellum SH16, S1A-15 (syncodChi42-1) and S2A-12 (syncodChi42-2) seemed to grow stronger and produce a higher number of mature pods, weight of 100 pods and weight of 100 seeds than line WAT-2 with the Chi42 gene and non-transgenic control. Moreover, lines S1A-15 and S2A-12 also resulted in higher seed quality in terms of lipid and protein content than in comparison to the WTA-2 line and the control. These findings suggest that chitinase transgenic peanuts containing one of two synthetic genes in peanut roots could be a promising candidate for peanut production against phytopathogenic fungi.
