Patent number: 10378019Abstract: Methods of pre-methylation of foreign DNA to improve genetic transformation in cyanobacterium. Two Type II methyltransferase-encoding genes, i.e., M (sll0729) and C (slr0214), were cloned from the chromosome of Synechocystis sp. PCC 6803 (hereafter Synechocystis 6803) and expressed in E. coli that harbors the integrative plasmid pBS-SPtK or pJU105. After pre-methylation in E. coli, the integrative plasmids were extracted and used for transformation of Synechocystis 6803. The results showed that expression of slr0214 in the integrative-plasmid-harboring E. coli cells before DNA preparation resulted in orders of magnitude higher efficiency in the following integrative transformation of Synechocystis 6803.Type: GrantFiled: September 1, 2015Date of Patent: August 13, 2019Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Bo Wang, Weiwen Zhang, Deirdre Meldrum
