MiRNA accumulation correlates with increased phloem cell proliferation in tomato <i>hawaiian skirt</i> mutants.

ABSTRACT:

Introduction

The cambium is the meristem responsible for production of plant vascular tissues, the xylem (wood) and phloem, during plant radial growth. Due to its internal location and relatively low cell number, the biology of the cambium remains less well understood compared to other plant meristems. The tomato hws mutant exhibits miRNA accumulation and produces a markedly enlarged phloem, suggesting a role for miRNAs in regulating vascular development. This study aims to identify the accumulated miRNAs associated with the vascular phenotype in hws mutants and characterize their impact on phloem development kinetics.

Methods

To achieve this, we analyzed the vascular phenotype of hws mutants using pedicel and stem sections examined using light and scann
