ABSTRACT
The low lipid content is one of the major bottlenecks to realize the industrialization of the algae biodiesel. Improvement of lipid content through global regulation to get high-yield generating algae is a good strategy. Leafy Cotyledon 2 (LEC2) is an important transcription factor for seed maturation and oil accumulation in Arabidopsis. However, there are few reports regarding adoption of LEC2 for lipid accumulation until now. In this study, LEC2 from Arabidopsis was cloned into the plant expression vector pCIMBIA1300 and transformed into C. sorokiniana through particle bombardment. One recombinant was screened by PCR, RT-PCR and Western blot analyses. Compared with the wild type one, the total lipid content in the recombinant increased one fold, which did not show effect on cell growth, indicating that LEC2 can efficiently enhance the lipid accumulation in C. sorokiniana.
