PP2 — Cucumis sativus

Summary

CSA_3G592130, also known as PP2, MYB40, CsPP2, or CsMYB40 in cucumbers (Cucumis sativus) on chromosome 3, encodes a Myb-domain transcription factor that binds DNA and transcription cis-regulatory regions. This gene is associated with the regulation of primary metabolic processes, including the shikimate pathway, phenylpropanoid and flavonoid anabolism, and lignin anabolism. It is linked to green leaf volatile biosynthesis, chlorophyll fluorescence, circadian rhythm, and responses to salt, cold, arsenic, and other organisms. Associations with root development and root weight traits (fresh and dry weight) have been observed, as well as connections to arsenic resistance, arsenate tolerance and uptake, and general stress tolerance. The encoded protein localises to both the cytoplasm and nucleus. Studies of related genes in other species link the family to drought tolerance.
