摘要： The identification of new genes involved in regulating cold tolerance in rice is urgent because low temperatures repress plant growth and reduce yields. Cold tolerance is controlled by multiple loci and involves a complex regulatory network. Here, we show that rice jacalin-related lectin (OsJRL) modulates cold tolerance in rice. The loss of OsJRL gene functions increased phenylalanine metabolism and flavonoid biosynthesis under cold stress. The OsJRL knock-out (KO) lines had higher phenylalanine ammonia-lyase (PAL) activity and greater flavonoid accumulation than the wild-type rice, Nipponbare (NIP), under cold stress. The leaves had lower levels of reactive oxygen species (ROS) and showed significantly enhanced cold tolerance compared to NIP. In contrast, the OsJRL overexpression (OE) lines had higher levels of ROS accumulation and showed lower cold tolerance than NIP. Additionally, the OsJRL KO lines accumulated more abscisic acid (ABA) and jasmonic acid (JA) under cold stress than NIP. The OsJRL OE lines showed increased sensitivity to ABA compared to NIP. We conclude that OsJRL negatively regulates the cold tolerance of rice via modulation of phenylalanine metabolism and flavonoid biosynthesis. OsJRL negatively regulates the cold tolerance of rice via modulation of phenylalanine metabolism and flavonoid biosynthesis.
