RNA-seq analysis of lignocellulose-related genes in hybrid Eucalyptus with contrasting wood basic density.

ABSTRACT:

Background

Wood basic density (WBD), the biomass of plant cell walls per unit volume, is an important trait for elite tree selection in kraft pulp production. Here, we investigated the correlation between WBD and wood volumes or wood properties using 98 open-pollinated, 2.4 to 2.8 year-old hybrid Eucalyptus (Eucalyptus urophylla x E. grandis). Transcript levels of lignocellulose biosynthesis-related genes were studied.

Results

The progeny plants had average WBD of 516 kg/m³ with normal distribution and did not show any correlations between WBD and wood volume or components of α-cellulose, hemicellulose and Klason lignin content. Transcriptomic analysis of two groups of five plants each with high (570-609 kg/m³) or low (378-409 kg/m³) WBD was
