Gene Details:

• Gene ID:
• Gene Symbol: PtaZFP2
• Gene Name: Cys2/His2 zinc finger protein
• Genome:
• Species: Populus tremula x Populus alba

Functional Descriptions:

• A single bending modified plant diameter growth and increased the relative abundance of PtaZFP2 transcripts. Integrals of longitudinal strains induced by bending on the responding tissues were highly correlated to local plant responses.
• Time course analysis of expression demonstrated that PtaZFP2 mRNA accumulated as early as 5 min in response to a controlled stem bending and is restricted to the organ where the mechanical stimulus is applied.
• The real-time quantitative Reverse Transcriptase Polymerase Chain Reaction experiments showed that PtaZFP2 was also rapidly up-regulated in poplar stems in response to gravitropism suggesting that PtaZFP2 is induced by different mechanical signals.
• Abundance of PtaZFP2 transcripts also increased highly in response to wounding and to a weaker extent to salt treatment and cold, which is consistent with the numerous putative cis-elements found in its regulatory region.
