In vitro regenerated shoots from various teak clones, i.e. the ITB, GT, P97, P96, P75, P20, and P108 clones were vacuum-infiltrated for 5 min in the suspension culture of A. tumefaciens. Seven days after selection period, the evidence of GUS activity in inoculated teak shoot-tissues was histochemically confirmed. The percentage of GUS-positive shoots per total numbers of evaluated shoots was calculated to estimate the efficiency of transient-transformation. Results indicated that the percentage of GUS-positive shoots varied among teak clones. The highest percentage of shoots with GUS activity (94.6%) was observed from the P108 clone and the lowest percentage (38.9%) was from the P20 clone. High frequencies of GUS expression were observed mostly in leaf and internodal tissues of teak shoots and less detected in young tissues of shoot-tips. © 2009 Academic Journals.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Agrobacterium-mediated transformation,Teak shoot-cultures,Tectona grandis L.f.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
