Table 6.

Perhaps  this property of the target enzyme, of the  transgenic T1 tomato allowed for better survival at high osmotic conditions and drought. ACBP might be stabilized the membranes, renewing the delivering of acyl CoA esters docking them close to fatty acid synthetase complexes. In conclusion, it might be deduced that T1 generation of transgenic tomato with the ugt and acb transgenes were valuable from economical point of view because of higher productivity and sustenance to environmental conditions.
