Using a functional genomics approach, four candidate genes (PtGT34A, PtGT34B, PtGT34C and PtGT34D) were identified in Pinus taeda. These genes encode CAZy family GT34 glycosyltransferases that are involved in the synthesis of cell-wall xyloglucans and heteromannans. The full-length coding sequences

BACKGROUND MicroRNAs (miRNAs) play key roles in diverse developmental processes, nutrient homeostasis and responses to biotic and abiotic stresses. The biogenesis and regulatory functions of miRNAs have been intensively studied in model angiosperms, such as Arabidopsis thaliana, Oryza sativa and

Vascular plants have two types of water-conducting cells, xylem vessel cells (in angiosperms) and tracheid cells (in ferns and gymnosperms). These cells are commonly characterized by secondary cell wall (SCW) formation and programmed cell death (PCD), which increase the efficiency of water

We isolated five members of the Aux/IAA gene family in loblolly pine (Pinus taeda L.). Degenerate primers complementary to conserved regions of angiosperm Aux/IAA genes were used to amplify fragments that were, in turn, used as probes to screen a cDNA library constructed from auxin-treated

Four male cone-specific promoters were isolated from the genome of Pinus radiata D. Don, fused to the beta-glucuronidase (GUS) reporter gene and analysed in the heterologous host Arabidopsis thaliana (L.) Heynh. The temporal and spatial activities of the promoters PrCHS1, PrLTP2, PrMC2 and PrMALE1

We characterized a Pinus radiata D. Don putative ortholog to the Arabidopsis thaliana (L.) Heynh. SHORT--ROOT gene (AtSHR) and analyzed its expression in different organs during vegetative development and in response to exogenous auxin during adventitious rooting. The predicted protein sequence

As part of a study to identify host plant genes regulated by fungal auxin during ectomycorrhiza formation, we differentially screened a cDNA library constructed from roots of auxin-treated Pinus pinaster (Ait.) Sol. seedlings. We identified three cDNAs up-regulated by auxin. Sequence analysis of one

Japanese red pine Pinus densiflora has 2 n=24 chromosomes and after FISH-detection of Arabidopsis-type (A-type) telomere sequences, many telomere signals were observed on these chromosomes at interstitial and proximal regions in addition to the chromosome ends. These interstitial and proximal signal

Growth, development and productivity of long-lived organisms such as forest trees are continuously challenged by abiotic stresses, and may also be greatly affected by predicted climatic change. As a first step toward creating stress-resistant maritime pine (Pinus pinaster Ait.) varieties by

Several members of WOX and KNOX gene families and several plant growth regulators, basically cytokinins and auxins, play a key role during adventitious caulogenesis in the conifer Pinus pinea. Similar to Arabidopsis thaliana, Pinus pinea shoot organogenesis is a multistep process. However, there are

In Pinus monticola (Dougl. ex D. Don), the class ten pathogenesis-related (PR10) proteins comprise a family of multiple members differentially expressed upon pathogen infection and other environmental stresses. One of them, PmPR10-1.13, is studied here by investigating its transcriptional regulation

The ability of four plant growth-promoting rhizobacteria, isolated in a previous study, to induce systemic resistance on Arabidopsis thaliana Col 0 against biotic and abiotic stress was evaluated. All the bacteria enhanced protection against the foliar pathogen Pseudomonas syringae DC3000 and

We have carried out a candidate-gene-based association genetic study in Pinus pinaster Aiton and evaluated the predictive performance for genetic merit gain of the most significantly associated genes and single nucleotide polymorphisms (SNPs). We used a second generation 384-SNP array enriched with

Needle maturation is a complex process that involves cell growth, differentiation and tissue remodelling towards the acquisition of full physiological competence. Leaf induction mechanisms are well known; however, those underlying the acquisition of physiological competence are still poorly

Heterobasidion annosum is widely known as a major root and butt rot pathogen of conifer trees, but little information is available on its interaction with the roots of herbaceous angiosperm plants. We investigated the infection biology of H. annosum during challenge with the angiosperm model
