Genome-wide identification and functional characterization of the LBD transcription factor gene family in Zanthoxylum armatum DC. reveal its potential role in leaf variation.

ABSTRACT:

Background

Leaf morphology plays a crucial role in forecasting the productivity and environmental adaptability of economically important trees. Plants with larger leaves usually have higher photosynthesis efficiency and can accumulate more nutrients, thereby increasing yield. In the natural population of Z. armatum, due to long-term selection, the leaves size and shape show rich diversity in different latitude regions. This diversity is the result of plants' adaptation to different environments. However, to date, no studies have systematically revealed the genetic mechanism of Z. armatum leaf variation. In higher plants, lateral organ boundaries domain (LBD) proteins comprise a unique family of transcription factors that play pivotal roles in the establishment of plant leaf polarit
