Two Arabidopsis promoters drive seed-coat specific gene expression in pennycress and camelina.

ABSTRACT:

Background

Pennycress and camelina are two important novel biofuel oilseed crop species. Their seeds contain high content of oil that can be easily converted into biodiesel or jet fuel, while the left-over materials are usually made into press cake meals for feeding livestock. Therefore, the ability to manipulate the seed coat encapsulating the oil- and protein-rich embryos is critical for improving seed oil production and press cake quality.

Results

Here, we tested the promoter activity of two Arabidopsis seed coat genes, AtTT10 and AtDP1, in pennycress and camelina by using eGFP and GUS reporters. Overall, both promoters show high levels of activities in the seed coat in these two biofuel crops, with very low or no expression in other tissues. Importantly, AtTT10 promoter
