Haplotype-resolved genome of a papeda provides insights into the geographical origin and evolution of Citrus.

The publication of several high-quality genomes has contributed greatly to clarifying the evolution of citrus. However, due to their complex genetic backgrounds, the origins and evolution of many citrus species remain unclear. We assembled de novo the 294-Mbp chromosome-level genome of a more than 200-year-old primitive papeda (DYC002).

CcRR5 interacts with CcRR14 and CcSnRK2s to regulate the root development in citrus.

Response regulator (RR) is an important component of the cytokinin (CK) signal transduction system associated with root development and stress resistance in model plants. However, the function of gene and the molecular mechanism on regulating the root development in woody plants such as citrus remain unclear. Here, we demonstrate that , a member of the type A RR, regulates the morphogenesis of root through interacting with CcRR14 and CcSnRK2s in citrus.

Potassium fulvic acid alleviates salt stress of citrus by regulating rhizosphere microbial community, osmotic substances and enzyme activities.

Salt stress damage to plants has been becoming a global concern for agriculture. The application of potassium fulvic acid (PFA) is a promising strategy to alleviate the damage to plants and improve soil quality. However, the study of PFA on plant growth and rhizosphere microbial community remains limited.

Mining key genes related to root morphogenesis through genome-wide identification and expression analysis of gene family in citrus.

Morphogenesis of root is a vital factor to determine the root system architecture. Cytokinin response regulators (RRs) are the key transcription factors in cytokinin signaling, which play important roles in regulating the root morphogenesis. In this study, 29 RR proteins, including 21 RRs and 8 pseudo RRs, were identified from the genome of citrus, and termed as CcRR1-21 and CcPRR1-8, respectively.
