Gene Details:

• Gene ID: Zm00001eb000690
• Gene Symbol: ZmHB58 RLD2
• Gene Name: rolled leaf2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Altered expression of microRNA165/166 (miR165/166) and its targets, ROLLED1 and ROLLED2 (RLD1/2), contributed to the changes in lbl1-rgd1 root growth and vascular patterning, as was evident by the altered root phenotype of Rld1-O semi-dominant mutant.
• Thus, LBL1/ta-siRNA module regulates root development, possibly by affecting auxin distribution and signalling, in crosstalk with miR165/166-RLD1/2 module. We further show that ZmLBL1 and its Arabidopsis homologue AtSGS3 proteins are functionally conserved.
• We show that maize LBL1, which is involved in ta-siRNA biogenesis, regulates root growth and branching possibly by modulating phytohormone auxin and miR165/166-RLD1/2 module.
