TLDR
High spatial resolution of the AspWood large-scale data set enabled identification of novel roles for characterized genes involved in xylan and cellulose biosynthesis, regulators of xylem vessel and fiber differentiation and lignification and regulation of the transcriptome underlying cambial growth and wood formation.Abstract:
Trees represent the largest terrestrial carbon sink and a renewable source of ligno-cellulose. There is significant scope for yield and quality improvement in these largely undomesticated species, ...read more

TL;DR: Evidence is provided that long‐read sequencing can complement short-read sequencing for cataloguing and quantifying eukaryotic transcripts and increase the understanding of the vital and dynamic process of shoot development.

Different Routes for Conifer- and Sinapaldehyde and Higher Saccharification upon Deficiency in the Dehydrogenase CAD1

TL;DR: The data suggest that, upon down-regulation of CAD1, coniferaldehyde is converted into ferulic acid and derivatives, whereas sinapaldehyde is either oxidatively coupled into S′(8-8)S′ and lignin or converted to sinapic acid and derivative, which is a major factor determining saccharification efficiency.

WUSCHEL-RELATED HOMEOBOX4 (WOX4)-like genes regulate cambial cell division activity and secondary growth in Populus trees
TL;DR: In Populus trees, PttWOX4 genes control cell division activity in the vascular cambium, and hence growth in stem girth, and expression profiling suggests that the CLE41 signaling pathway is an evolutionarily conserved program for the regulation of vascular c Cambium activity between angiosperm and gymnosperm tree species.

Recent Advances in the Transcriptional Regulation of Secondary Cell Wall Biosynthesis in the Woody Plants.
TL;DR: This article synthesizes recent progress on the transcriptional regulation of SCW biosynthesis in Arabidopsis and contrast to what is known in woody species and evaluates progress in related emerging regulatory machineries targeting transcription factors in this complex regulatory network of SCw biosynthesis.

Auxin‐mediated Aux/IAA‐ARF‐HB signaling cascade regulates secondary xylem development in Populus
Changzheng Xu,Yun Shen,Fu He,Xiaokang Fu,Hong Yu,Wanxiang Lu,Yongli Li,Chaofeng Li,Chaofeng Li,Di Fan,Hua Cassan Wang,Keming Luo +11 more
TL;DR: The results suggest that the Aux/IAA9-ARF5 module is required for auxin signaling to regulate wood formation via orchestrating the expression of HD-ZIP III transcription factors in poplar.

Moderated estimation of fold change and dispersion for RNA-seq data with DESeq2
TL;DR: This work presents DESeq2, a method for differential analysis of count data, using shrinkage estimation for dispersions and fold changes to improve stability and interpretability of estimates, which enables a more quantitative analysis focused on the strength rather than the mere presence of differential expression.

Trimmomatic: a flexible trimmer for Illumina sequence data
TL;DR: Timmomatic is developed as a more flexible and efficient preprocessing tool, which could correctly handle paired-end data and is shown to produce output that is at least competitive with, and in many cases superior to, that produced by other tools, in all scenarios tested.

Emergence of Scaling in Random Networks
TL;DR: A model based on these two ingredients reproduces the observed stationary scale-free distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems.
