A kind of wheat anti-ear germination gene tazfp18 and its application

Abstract

The invention discloses a wheat pre-harvest sprouting tolerance gene TaZFP18. The gene includes the nucleotide sequence shown as SEQ ID NO.1, or includes the nucleotide sequence shown as complementary with the SEQ ID NO.1 sequence, and the gene encodes a CCCH type zinc finger protein 18 and can serve as the molecular marker gene of a wheat pre-harvest sprouting tolerance variety. The wheat pre-harvest sprouting tolerance gene TaZFP18 is a novel major wheat pre-harvest sprouting tolerance gene, can be utilized to develop a molecular marker so as to rapidly identify whether wheat belongs to the pre-harvest sprouting tolerance variety or not and provides a new gene resources for breeding of wheat pre-harvest sprouting tolerance varieties.

Description

technical field

[0001] The invention relates to the technical field of crop genetics and breeding, in particular to a wheat anti-ear germination gene TaZFP18 and its application. Background technique

[0002] Pre-harvest sprouting (PHS) refers to the phenomenon that the crops encounter rainy weather before harvesting, which leads to the direct germination of seeds on the ears. Ear germination before harvest in wheat will seriously reduce the stability of yield and quality. The longer the time of continuous rainy weather before harvest, the more serious the ear germination hazard. Therefore, cultivating wheat varieties with strong ear germination resistance can help reduce this risk.

[0003] The factors affecting ear germination mainly include external environmental factors and internal factors. Light and temperature are the main environmental factors; internal factors mainly include seed dormancy, seed coat color, panicle shape, grain water absorption characteristics, α-...
