Migration and Attacking Ability of Bursaphelenchus mucronatus in Pinus thunbergii Stem Cuttings [PDF]

The Plant Pathology Journal, 2016
To understand how Bursaphelenchus xylophilus kills pine trees, the differences between the effects of B. xylophilus and B. mucronatus on pine trees are usually compared. In this study, the migration and attacking ability of a non-pathogenic B. mucronatus

Storage domains of coniferin in cell wall forming tracheid cells in Pinus thunbergii stems evaluated by cryo microscopic chemical analyses [PDF]

Scientific Reports
We investigated how lignin precursors are stored and used during secondary-wall formation in Pinus thunbergii stems, addressing the current lack of quantitative, spatially resolved information, especially on monolignols and their glucosides.

Colonization by the Mycorrhizal Helper Bacillus pumilus HR10 Is Enhanced During the Establishment of Ectomycorrhizal Symbiosis Between Hymenochaete sp. Rl and Pinus thunbergii [PDF]

Frontiers in Microbiology, 2022
There are complex interactions between mycorrhizal helper bacteria (MHBs) and ectomycorrhizal (ECM) fungi, with MHBs promoting mycorrhizal synthesis and ECM fungi regulating plant rhizobacterial colonization, diversity, and function.

Construction of genetic linkage map and identification of a novel major locus for resistance to pine wood nematode in Japanese black pine (Pinus thunbergii) [PDF]

BMC Plant Biology, 2019
Background Pine wilt disease (PWD), which is caused by the pine wood nematode (PWN) Bursaphelenchus xylophilus, is currently the greatest threat to pine forests in Europe and East Asian countries including Japan.

Establishment of embryogenic Pinus thunbergii Parl. suspension cultures: growth parameters, dynamic analysis, and plant regenerative capacities [PDF]

BMC Plant Biology
Background Pinus thunbergii is an economically important conifer species that plays a fundamental role in forest ecosystems. However, the population has declined dramatically in recent years as a result of the pine wilt disease outbreak. Thus, developing

Quantitative Trait Loci Analysis Based on High-Density Mapping of Single-Nucleotide Polymorphisms by Genotyping-by-Sequencing Against Pine Wilt Disease in Japanese Black Pine (Pinus thunbergii) [PDF]

Frontiers in Plant Science, 2022
Identifying genes/loci for resistance to pine wilt disease (PWD) caused by the pine wood nematode (PWN) is beneficial for improving resistance breeding in Pinus thunbergii, but to date, genetic information using molecular markers has been limited.

Different Waterlogging Depths Affect Spatial Distribution of Fine Root Growth for Pinus thunbergii Seedlings [PDF]

Frontiers in Plant Science, 2021
The increase of waterlogged environments at forests and urban greenery is of recent concern with the progress of climate change. Under waterlogging, plant roots are exposed to hypoxic conditions, which strongly affect root growth and function.
