Key Points

Gene expression patterns show significant variations, suggesting roles in leaf greening.
DYW-type PPR genes are linked to chloroplast development and chlorotic leaf transformation.
Analysis of transcriptome data highlights structural changes and their potential regulatory pathways.
These findings may enable targeted interventions to enhance chlorophyll production in crops.

Abstract

In conclusion, this study elucidated the structural variations and dynamic expression patterns of the DYW-type PPR gene associated with chlorotic leaves in pears, offering novel insights and potential regulatory pathways relevant to chloroplast development and the transformation of chlorotic leaves to green in pears.
