Using modern molecular biology technology, how to mine wheat drought resistance genes, reveal the molecular mechanism and genetic network of wheat drought resistance specific regulation, is of great significance to wheat drought resistance genetic improvement, and it is also a current research problem in wheat molecular genetic breeding
.

According to relevant experts in wheat genetics and breeding, the existing research literature shows that among the many wheat genes, the gene TaNAC071-A has the function of drought resistance
.

TaNAC071-A

The team of Academician Kang Zhensheng from the College of Plant Protection of Northwest A&F University successfully cloned a wheat gene TaNAC071-A and revealed its molecular mechanism regulating wheat drought resistance by using the research strategy of whole-genome association analysis of wheat natural variant populations from different sources

TaNAC071-A

The research team further performed a detailed sequencing analysis of a large number of wheat material TaNAC071-A gene sequences, and found that in the drought-resistant wheat material, TaNAC071-A has a special fragment, and this fragment is related to a protein factor.
Combining, resulting in drought resistance
.

In addition, the team introduced the TaNAC071-A gene into drought-sensitive wheat materials through hybridization and continuous backcross methods, and found that the drought resistance of wheat seedlings was effectively improved

TaNAC071-A TaNAC071-A TaNAC071-A

It is understood that the team of Academician Kang Zhensheng also discovered multiple drought resistance genes in wheat
.

Their comprehensive research showed that TaNAC071-A has a stronger function in regulating the drought resistance of wheat

TaNAC071-A

Experts and scholars related to wheat genetics and breeding believe that the discovery of wheat drought resistance gene TaNAC071-A provides important genetic resources and selection targets for the breeding of new wheat varieties with drought resistance
