Abstract

The invention discloses a brassica napobrassica growth regulatory factor gene GRF2 and an application thereof. A base sequence of the gene is a nucleotide sequence represented by SEQ ID NO:1; or a gene sequence of another crop, wherein the gene sequence has no less than 70% homology with that represented by SEQ ID NO:1; or a mutant allele or a derivative obtained after one or more nucleotides areprocessed through addition, substitution, insertion or deletion. As a result of researches, the expression level of the gene in brassica napobrassica high-oil parents and high-oil mixture crops is higher than that in low-oil parents and low-oil mixture crops. A transgene result obtained by using arabidopsis thaliana as an acceptor verified that, with the over-expression of the gene, arabidopsis thaliana oil content is improved, and a 1000-seed weight of arabidopsis thaliana is increased. The invention also provides an application of brassica napobrassica growth regulatory factor gene BnGRF2 in improving the 1000-seed weight and oil content of plants such as arabidopsis thaliana. Therefore, the gene has good application prospect in oil-yield seed breeding of brassica napobrassica and otheroil crops.

Description

technical field

[0001] The invention relates to the field of plant genetic engineering, more specifically relates to a rapeseed growth regulator gene GRF2, and also relates to the application of a rapeseed growth regulator gene GRF2. Background technique

[0002] The production of oil crops not only plays an important role in national economic and social development, but also is one of the main factors to promote the sustainable development of China's agriculture. At present, China's vegetable oil production can only meet 1 / 2-2 / 3 of the domestic consumption demand, relying heavily on imports. For example, in 2005, China imported more than 6 million tons of vegetable oil and 24 million tons of soybeans, making it the world's largest oil importer. With the growth of population and the improvement of people's living standards, it is estimated that the consumption of edible vegetable oil in China will increase to 25 million tons by 2010. According to the current production scal...
