Wheat male-sterility gene wms and its anther-specific expression promoter and uses thereof

The present invention provides a novel gene WMS conferring wheat male sterility, its anther-specific expression promoter, and uses of the same. In wheat, a well-known gene Ms2 causing dominant male sterility has been widely applied in recurrent selection in China. A RNA-seq approach was performed to reveal the anther-specific transcriptome in a pair of Ms2 isogenic lines, 'Lumai 15' and 'Lumai 15+Ms2'. As a result, a WMS gene was identified showing anther-specific expression at the early stage of meiosis and only in wheat carrying the Ms2 gene. The regulation of WMS could alter plant male fertility. The promoter of WMS was found to comprise anther-specific activity. Thus, the present invention might be used to achieve anther-specific gene expression, to develop male sterility in various plant species, to establish recurrent selection in various plant species, and to assist hybrid seed production.

Vetor compreendendo dna isolado e promotor de expressão específico de antera

GENE WMS DE MACHO-ESTERILIDADE DE TRIGO E SEU PROMOTOR DE EXPRESSÃO ESPECÍFICO DE ANTERA E USOS DOS MESMOS. A presente invenção proporciona um novo gene WMS que confere macho-esterilidade de trigo, o seu promotor de expressão específico de antera e usos dos mesmos. No trigo, um gene Ms2 bem conhecido que causa macho-esterilidade dominante tem sido amplamente aplicado na seleção recorrente na China. Uma abordagem de RNA- seq foi realizada para revelar o transcritoma específico de antera em um par de linhas isogênicas de Ms2, 'Lumai 15' e 'Lumai 15 + Ms2'. Como resultado, um gene WMS foi identificado mostrando expressão específica de antera no estágio inicial da meiose e apenas em trigo carregando o gene Ms2. A regulação do WMS poderia alterar a macho-fertilidade da planta. Verificou-se que o promotor de WMS compreende uma atividade específica de antera. Assim, a presente invenção pode ser usada para alcançar a expressão de genes específicos da antera, para desenvolver macho-esterilidade em várias espécies de plantas, para estabelecer a seleção recorrente em várias espécies de plantas e para auxiliar a produção de sementes híbridas.
