Ectopic expression of maize gene ZmDUF1645 in rice affects rice grain traits and cold tolerance.

ABSTRACT: The DUF protein family is a class of functional proteins containing conserved structural domains that are widely involved in biological processes such as plant seed development, yield formation and response to adversity. Previous research has demonstrated that the heterologous expression of ZmDUF1645 from maize (Zea mays) in rice (Oryza sativa L.) markedly enhances grain yield and influences drought tolerance. However, its effects under other stress conditions remain poorly understood. This study aims to elucidate the role of ZmDUF1645 in rice grain traits and cold tolerance. To this end, the maize gene ZmDUF1645 was expressed in rice, resulting in transgenic plants that exhibited significantly increased yield but reduced grain quality. Further analysis revealed that ZmDUF1645, with functi
