Abstract

Belonging to the field of gene engineering, the invention relates to an AP2 / EREBP transcription factor bNwrI1 gene and an application thereof in adjusting plant seed photosynthesis and oil and fat anabolism. The transcription factor is extracted from brassica napus and is one of the following polypeptides: a polypeptide provided with an amino acid sequence as SEQ ID NO:2 indicates, a polypeptide which is formed with the amino acid sequence replaced, deleted and added by one or more than one amino acid residue and provided with the amino acid sequence and a polypeptide with functions thereof derivating from the polypeptide provided with the amino acid sequence. The transcription factor and coding genes thereof enjoy extensive application value in plant culturing field and can enable the plant to coordinately regulate photosynthesis and fatty acid anabolism, improves seed photosynthesis and oil and fat accumulation capacity, thus improving plant yield and oil content as well as correlated characteristics.

Description

technical field

[0001] The invention belongs to the field of genetic engineering and relates to an AP2 / EREBP transcription factor BnWRI1 gene and its application in regulating plant seed photosynthesis and oil synthesis and metabolism. Background technique

[0002] In addition to its important nutritional value to humans, vegetable oils are also used as raw materials for a wide range of non-edible products, especially as global energy is becoming increasingly tense, and the use of vegetable oils to produce renewable energy has become an important strategic choice for countries around the world to deal with energy crises. Increasing oil production per unit area is the goal that oil crop breeding has always pursued. Oil content and yield per unit area are two components of oil production per unit area, and are also important determinants of oil crop production efficiency (Li Yunchang et al., Chinese Journal of Oil Crops 28:92-96, 2006).

[0003] The economic trait of seed oil...
