Draft genomes and assemblies of the ectomycorrhizal basidiomycetes hr and jo associated with chestnut trees.

The earthball , an ectomycorrhizal basidiomycete belonging to the Sclerodermataceae family, serves as a significant mutualistic tree symbiont globally. Originally, two genetically sequenced strains of this genus were obtained from fruiting bodies collected under chestnut trees (). These strains were utilized to establish ectomycorrhizal roots of chestnut seedlings.

Plant growth-promoting rhizobacterium Pseudomonas sp. CM11 specifically induces lateral roots.

Plant growth-promoting rhizobacteria are involved in altering secondary root (SR) formation, but hitherto there has been no distinction between the different types of SRs upon induction of soil biota, and the genetic pathways involved. By using plate and soil systems, we studied the effects of the Pseudomonas strains CM11 and WCS417 on plant performance with a focus on root development. Through a combination of cellular, molecular and genetic analyses, we investigated the type of SRs induced upon CM11 and WCS417 root inoculation using genetic pathways associated with specific SR types.

Plant-specific histone deacetylases are essential for early and late stages of Medicago nodule development.

Legume and rhizobium species can establish a nitrogen-fixing nodule symbiosis. Previous studies have shown that several transcription factors that play a role in (lateral) root development are also involved in nodule development. Chromatin remodeling factors, like transcription factors, are key players in regulating gene expression.

Hybrid de novo genome assembly of Chinese chestnut (Castanea mollissima).

Background: The Chinese chestnut (Castanea mollissima) is widely cultivated in China for nut production. This plant also plays an important ecological role in afforestation and ecosystem services. To facilitate and expand the use of C.

Transforming, Genome Editing and Phenotyping the Nitrogen-fixing Tropical Cannabaceae Tree Parasponia andersonii.

Parasponia andersonii is a fast-growing tropical tree that belongs to the Cannabis family (Cannabaceae). Together with 4 additional species, it forms the only known non-legume lineage able to establish a nitrogen-fixing nodule symbiosis with rhizobium. Comparative studies between legumes and P.

Plant-Specific Histone Deacetylases HDT1/2 Regulate Expression to Control Arabidopsis Root Meristem Cell Number.

Root growth is modulated by environmental factors and depends on cell production in the root meristem (RM). New cells in the meristem are generated by stem cells and transit-amplifying cells, which together determine RM cell number. Transcription factors and chromatin-remodeling factors have been implicated in regulating the switch from stem cells to transit-amplifying cells.

MAPK-triggered chromatin reprogramming by histone deacetylase in plant innate immunity.

Background: Microbial-associated molecular patterns activate several MAP kinases, which are major regulators of the innate immune response in Arabidopsis thaliana that induce large-scale changes in gene expression. Here, we determine whether microbial-associated molecular pattern-triggered gene expression involves modifications at the chromatin level.

Results: Histone acetylation and deacetylation are major regulators of microbial-associated molecular pattern-triggered gene expression and implicate the histone deacetylase HD2B in the reprogramming of defence gene expression and innate immunity.

The complete mitochondrial genome of Paecilomyces hepiali (Ascomycota, Eurotiomycetes).

Paecilomyces hepiali, belonging to the Eurotiales order Ascomycota, is an endoparasitic fungus that commonly exists in the natural Cordyceps sinensis anamorph stage. Here, we report the complete mitochondrial DNA sequences of P. hepiali for the first time.
