Multifaceted Role of PheDof12-1 in the Regulation of Flowering Time and Abiotic Stress Responses in Moso Bamboo (Phyllostachys edulis).

ABSTRACT: DNA binding with one finger (Dof) proteins, forming an important transcriptional factor family, are involved in gene transcriptional regulation, development, stress responses, and flowering responses in annual plants. However, knowledge of Dofs in perennial and erratically flowering moso bamboo is limited. In view of this, a Dof gene, PheDof12-1, was isolated from moso bamboo. PheDof12-1 is located in the nucleus and has the highest expression in palea and the lowest in bract. Moreover, PheDof12-1 expression is high in flowering leaves, then declines during flower development. The transcription level of PheDof12-1 is highly induced by cold, drought, salt, and gibberellin A3 (GA₃) stresses. The functional characteristics of PheDof are researched for the first time in Ar
