Article Synopsis
- * This study identified 109 C2H2 genes, focusing on the PtrC2H2.2 subfamily, which underwent significant evolutionary changes, suggesting its importance in plant stress responses.
- * The key finding reveals that the PtrC2H2.2-6 gene plays a negative regulatory role in osmotic stress; plants with reduced expression of this gene have better tolerance, pointing to potential genetic approaches for developing drought-resistant trees.
Abscisic acid (ABA) signaling has been implicated in plant responses to water deficit-induced osmotic stress. However, the underlying molecular mechanism remains unelucidated. This study identified the RING-type E3 ubiquitin ligase RING ZINC FINGER PROTEIN1 (PtrRZFP1) in poplar (Populus trichocarpa), a woody model plant.

- Forest trees encounter various abiotic stressors like drought, high salinity, and heavy metals, which can negatively impact their quality and yield.
- The study focused on the RING ZINC FINGER PROTEIN (RZFP) gene family, identifying eight PtrRZFPs in the Populus genome and analyzing their structures and evolution.
- Results showed that certain PtrRZFPs are involved in stress responses, with PtrRZFP1 specifically enhancing drought tolerance when overexpressed, highlighting its potential for genetic engineering in improving drought resistance in forest trees.
