BackgroundPrevious research has demonstrated that ectopic expression of Ran-binding protein (RanBP) in Arabidopsis results in more axillary buds and reduced apical dominance compared to WT plants. However, the function of RanBP in poplar, which has very typical secondary growth, remains unclear. Here, the Populus deltoides (Marsh.) RanBP gene (PdRanBP) was isolated and functionally characterized by ectopic expression in a hybrid poplar (P. davidiana Dode × P. bolleana Lauche).ResultsPdRanBP was… 
Proline-rich protein gene PdPRP regulates secondary wall formation in poplar.
The Osmotin-Like Protein Gene PdOLP1 Is Involved in Secondary Cell Wall Biosynthesis during Wood Formation in Poplar
TLDR
Results suggest that PdOLP1 is a negative regulator of secondary wall biosynthesis and may be valuable for manipulating secondary cell wall deposition to improve carbon fixation efficiency in tree species.

Molecular cloning and functional analysis of the Populus deltoides remorin gene PdREM.
TLDR
Light is shed on the molecular mechanism of PdREM in P. deltoides growth and development, and the foundation for future functional genomics research into wood formation and the genetic engineering of forest trees with improved wood quality traits is laid.
Poplar PdMYB221 is involved in the direct and indirect regulation of secondary wall biosynthesis during wood formation
TLDR
It is shown that PdMYB221, a poplar ortholog of the Arabidopsis R2R3-MYB transcription factor AtMYB4, directly regulates secondary wall biosynthesis during wood formation and may be involved in the negative regulation of secondary wall formation through the direct and indirect suppression of the gene expression of secondarywall biosynthesis.
EgMYB1, an R2R3 MYB transcription factor from eucalyptus negatively regulates secondary cell wall formation in Arabidopsis and poplar.
TLDR
It is strongly suggested that EgMYB1 is a repressor of secondary wall formation and provide new opportunities to dissect the transcriptional regulation of secondary cell walls biosynthesis.
Phytochrome-mediated differential gene expression of plant Ran/TC4 small G-proteins
TLDR
Ran gene expression is differentially regulated by various light sources and phytochrome-mediated signaling pathways, resulting in reduced expression of Ran/TC4 genes in Arabidopsis plants.
MYB transcription factors are differentially expressed and regulated during secondary vascular tissue development in hybrid aspen
TLDR
Three MYB genes showed different expression patterns in various organs, tissues and stem sub-sections representing different developmental stages of vascular tissue formation, and a higher transcript level of caffeoyl-CoA 3-O-methyltransferase was found in the phloem of the transgenic plants, suggesting that PttMYB21a might function as a transcriptional repressor.
PtoMYB92 is a Transcriptional Activator of the Lignin Biosynthetic Pathway During Secondary Cell Wall Formation in Populus tomentosa.
TLDR
Subcellular localization and transcriptional activation analysis suggest that PtoMYB92 is a nuclear-localized transcriptional activator in the lignin biosynthetic pathway during secondary cell wall formation in poplar by controlling the biosynthesis of monolignols.
Overexpression of RAN1 in Rice and Arabidopsis Alters Primordial Meristem, Mitotic Progress, and Sensitivity to Auxin1
TLDR
The results suggest that Ran protein was involved in the regulation of mitotic progress, either in the shoot apical meristem or the root meristen zone in plants, where auxin signaling is involved.
Functional Identification of Wood-property Candidate Gene PdCYTOB in Populus deltoides
We used quantitative real-time RT-PCR to investigate the tissue expression patterns of cytokinin binding-protein PdCYTOB, which is related to the wood properties of Populus deltoides . PdCYTOB was
Overexpression of OsRAN2 in rice and Arabidopsis renders transgenic plants hypersensitive to salinity and osmotic stress
TLDR
Three ABA- or stress-responsive genes, AtNCED3, AtPLC1, and AtMYB2, encoding a key enzyme in ABA synthesis, a phospholipase C homologue, and a putative transcriptional factor, respectively, were shown to have differentially induced expression under salinity and ABA treatments in transgenic and wild-type Arabidopsis plants.
Characterisation of a pine MYB that regulates lignification.
TLDR
Electrophoretic mobility shift assays showed that recombinant PtMYB4 protein is able to bind to DNA motifs known as AC elements, consistent with the hypothesis that PtmyB4 is sufficient to induce lignification, and that it may play this role during wood formation in pine.
