ABSTRACT The CLAVATA3 (CLV3)/EMBRYO SURROUNDING REGION‐RELATED(CLE) peptides play crucial roles in plentiful plant developmental and adaptive processes. In this study, we demonstrate that Arabidopsis CLE14 acts as a critical regulator of root hair elongation. Compared to the wild‐type (WT) plant, CRISPR/Cas9‐generated cle14‐cr mutants exhibit reduced length, whereas overexpression promotes consistence, synthetic peptide also facilitates However, peptide‐induced elongation is significantly...
The grain boundaries of perovskite polycrystalline are regarded as a defect region that not only provides carrier recombination sites but also introduces device degradation pathways.
