Gene Details:

• Gene ID:
• Gene Symbol: PtaRHE1
• Gene Name: RING-H2 ATL family protein1
• Genome: C9D740
• Species: Populus tremula × Populus alba

Functional Descriptions:

• PtaRHE1, a Populus tremula × Populus alba RING-H2 protein of the ATL family, has a regulatory role in secondary phloem fibre development.
• Within stem secondary vascular tissues, PtaRHE1 and its corresponding protein are expressed predominantly in the phloem.
• The downregulation of PtaRHE1 in poplar by artificial miRNA triggers alterations in phloem fibre patterning, characterized by an increased portion of secondary phloem fibres that have a reduced cell wall thickness and a change in lignin composition, with lower levels of syringyl units as compared with wild-type plants.
• Several candidate genes possibly associated with the altered phloem fibre phenotype observed in amiRPtaRHE1 poplar were identified. Altogether, our data suggest a regulatory role for PtaRHE1 in secondary phloem fibre development.
• amiRPtaRHE1 poplars have alteration in the pattern of secondary phloem fibre development.
