Disease relevance of acsA

• The acsA and acsB genes, which are involved in cellulose synthesis in Acetobacter xylinum, were transferred into pollen grains of brown cotton with the aim of improving its fiber quality by incorporating useful prokaryotic features into the colored cotton plants [1].
• Our study suggests that transformation through vacuum infiltration and Agrobacterium mediated transformation can be an efficient way to introduce foreign genes into the cotton pollen grain and that cotton fiber quality can be improved with the incorporation of the prokaryotic genes acsA and acsB [1].

High impact information on acsA

• Of 1,039 seeds from 312 bolls pollinated with transformed pollen grains, 17 were able to germinate and grow into seedlings for more than 3 weeks in a nutrient medium containing 50 mg/l hygromycin; eight of these were transgenic plants integrated with acsA and acsB, yielding a 0.77% transformation rate [1].
• The integration and expression of acsA, acsB and GUS in the genome of transgenic plants were analyzed with Southern blot hybridization, PCR, histochemical GUS assay and Northern blot hybridization [1].
• Transformation was carried out in cotton pollen-germinating medium, and transformation was mediated by vector pCAMBIA1301, which contains a reporter gene beta-glucuronidase (GUS), a selectable marker gene, hpt, for hygromycin resistance and the genes of interest, acsA and acsB [1].
