Abstract:

Global change of climate has made great challenges to the crop productions and economical stabilities. The creation of adaptive species under the extreme environmental change is one of the primary goals in modern crop breeding process. As one of the most important crops in the world, maize have lost substantial genetic diversities during domestication, especially the loci that respond to the biotic and abiotic stress. Finding and utilizing the genetic diversity lost during maize domestication in wild species and landrace will provide new light for the creation of new adaptive varieties. In this review, we firstly introduce the discoveries and classification of teosinte(wild relatives of maize), and then summarize the traits and genomic difference between teosinte and maize, the genetic mechanism of divergence of maize and teosinte basing on genetics, population genetics, molecular biology, revealing the importance of teosinte in the development of maize genetics from multiple perspectives. Finally, we prospect the key role of teosinte in maize future breeding process under climate changes.

Key words: climate change, maize, adaptability, wild species
