An Axiom SNP genotyping array for Douglas-fir

open access: yesBMC Genomics, 2020
Background In forest trees, genetic markers have been used to understand the genetic architecture of natural populations, identify quantitative trait loci, infer gene function, and enhance tree breeding.

Stand Dynamics and Disturbance History of Champlain Valley Clayplain Forests [PDF]

open access: yes, 2017
Studies of stand dynamics can explain how species interactions and disturbances drive forest structure and recruitment patterns of tree species. It is difficult to generate an understanding of stand dynamics and successional trends of forests in areas ...

Tanzanian forest tree plot diversity and elevation [PDF]

open access: yes, 1999
Observed variation in species richness on ecological gradients and between regions has attracted several different explanations. Climatic factors, such as energy availability, precipitation and mean annual temperature, are frequently cited to explain ...

Telomere‐to‐Telomere Genomes Reveal that Multiscale Evolution Shapes the Largest Metabolic Arsenal of Diaporthe Fungi

open access: yesAdvanced Science, EarlyView.
This study presents the first telomere‐to‐telomere genomes and population resources for Diaporthe pathogens, uncovering the largest known fungal repertoire of secondary metabolite gene clusters. Structural variations and horizontal gene transfer drive cluster diversification, while specific rapidly evolving clusters control virulence, offering novel ...

Gnotobiotic evaluation of Dalbergia sissoo genotypes for resistance against Fusarium solani via dual culture set up

open access: yesJournal of Genetic Engineering and Biotechnology, 2021
Background Dalbergia sissoo (shisham), an important multipurpose tree native to the Indian subcontinent and also planted in other countries, has been afflicted with large scale mortality in all age groups due to wilt disease, causing huge economic losses.

Mass Spectrometry Imaging‐Assisted Discovery of Gallotannin Biosynthetic Genes in the Root of Paeonia suffruticosa

open access: yesAdvanced Science, EarlyView.
An integrated approach combining mass spectrometry imaging, transcriptomics, and phylogenetic analysis facilitated the efficient identification of genes involved in gallotannin biosynthesis in Paeonia suffruticosa. As a result, a key UGT and several SCPL acyltransferases responsible for biosynthesizing pentagalloylglucose were successfully identified ...

Modeling of radial growth curves and radial variation of basic density in Chamaecyparis obtusa planted in two progeny test sites

open access: yesJournal of Wood Science
The objectives of the present study are to clarify the effect of macro- and micro-environment on the radial growth patterns and radial variation patterns of basic density in hinoki cypress (Chamaecyparis obtusa (Sieb. et Zucc.) Endl.).

Negative association in uniform forests and connected graphs

open access: yes, 2003
We consider three probability measures on subsets of edges of a given finite graph $G$, namely those which govern, respectively, a uniform forest, a uniform spanning tree, and a uniform connected subgraph. A conjecture concerning the negative association

On the Origins of Toughness in Corymbia calophylla (Marri Tree) Nuts

open access: yesAdvanced Science, EarlyView.
We uncover the natural toughening mechanisms of the marri nut, including fiber pullout, crack deflection, and a viscoelastic matrix, which enable exceptional energy absorption and ductility comparable to Teflon, with an elastic modulus similar to acrylic.
