Cloned (Comment) Organism
recombinant expression of hybrid gene of Synechococcus vulcanus DELTA9 (desC) acyl-lipid desaturase in Nicotiana tabacum cv. Wisconsin, as chimeric enzyme DesC-LicBM3 with reporter thermostable lichenase of Clostridium thermocellum, expression with or without the sequence coding for transit peptide of Rubisco small subunit of Arabidopsis thaliana under control of the 35S CaMV constitutive promoter using the Agrobacterium tumefaciens strain GV3101-mediated transformation method, measurement of recombinant lichenase activity. Plants expressing RTP::desC::licBM3 gene coding for DELTA9 desaturase with the transit pepride for transport into chloroplasts exhibit a significant increase of alpha-linolenic acid (DELTA9,12,15-18:3) portion accompanied by decrease of DELTA9,12-18:2 level while the part of the third major fatty acid, palmitic acid, remains unchanged Thermostichus vulcanus

additional information establishment of transgenic lines of Nicotiana tabacum expressing hybrid genes of Synechocystis sp. PCC 6803 DELTA12 (desA) acyl-lipid desaturase and Synechococcus vulcanus DELTA9 (desC) acyl-lipid desaturase with or without sequence coding for transit peptide of Rubisco small subunit of Arabidopsis thaliana under control of a constitutive promoter. Reliable increase of linoleic acid portion (C18:2, DELTA9,12) accompanied with decrease of alpha-linolenic acid (C18:3, DELTA9,12,15) relative amount is detected for plants expressing hybrid desA::licBM3 gene. No reliable changes are detected in fatty acid profiles and unsaturation index of plants transformed with DELTA9 desaturase gene desC::licBM3 lacking signals of intracellular targeting while expression of this gene with Arabidopsis thaliana Rubisco small subunit transit peptide sequence caused growth of C18:3 alpha-linolenic acid part simultaneously with reduction of C18:2 linoleic acid part, as well as increase of unsaturation index. No changes in relative amount of DELTA9monounsaturated fatty acids were observed in any of studied lines. All plants expressing desaturase genes exhibited enhanced levels of superoxide dismutase (SOD) activity after cold treatment in contrast to control lines with suppressed SOD activity after cold treatment Thermostichus vulcanus
