rDNA-FISH pattern in selected Hieracium species representing different ploidy levels

open access: yesActa Societatis Botanicorum Poloniae, 2023
Polyploid species of Hieracium s.str. are near-obligatory apomicts capable of producing non-reduced pollen grains and intrageneric crossing with sexual diploid species.

Oral Astilbin Nanogels Modulate Senescence‐Associated CD4+ T Cells and Promote Treg Induction in Aged Mice with Colitis

open access: yesAdvanced Science, EarlyView.
Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...

Placing very long branch taxa in the plant tree of life: A case study with Dioscoreales mycoheterotrophs

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The inclusion of heterotrophic plants in broader systematic studies is challenging due to substantial morphological modification, gene loss, and accelerated substitution rates following photosynthesis loss. In particular, inclusion of very long branch (VLB) taxa with highly elevated rates may lead to phylogenomic misinference.

Identification of white clover (Trifolium repens L.) cultivars using molecular markers

open access: yesPlant, Soil and Environment, 2004
The different molecular analysis for specification of white clover (Trifolium repens L.) populations was studied between 2002 and 2003. RAPD, SSR (microsatellites), rDNA and PCR-RFLP markers were used for this study.

Diversity and authentication of Rubus accessions revealed by complete plastid genome and rDNA sequences

open access: yesMitochondrial DNA. Part B. Resources, 2021
Complete plastid genome (plastome) and ribosomal DNA (rDNA) sequences of three Rubus accessions (two Rubus longisepalus and one R. hirsutus) were newly assembled using Illumina whole-genome sequences. Rubus longisepalus Nakai and R.

Plant condensin II is required for the correct spatial relationship between centromeres and rDNA arrays

open access: yesNucleus, 2019
Plants possess the structural maintenance of chromosome (SMC) protein complexes cohesin, condensin, and SMC5/6, which function in fundamental biological processes such as sister chromatid cohesion, chromosome condensation and segregation, and damaged DNA

Inheritance of the rDNA spacer in D. melanogaster [PDF]

open access: yesMolecular and General Genetics MGG, 1983
We studied the organization of rDNA spacer sequences within several rDNA loci in D. melanogaster. Every locus showed many discrete length classes of rDNA spacer, ranging from 2.4 kb to about 20 kb. Different loci show characteristic distributions of spacers within the various length classes.

Functional Diversity and Oleaginous Potential of Fungal Strains From Hawaiian Soil Ecosystems

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Fungi represent an important but underexplored resource for microbial lipid production, including nutritionally valuable polyunsaturated fatty acids. Hawaiian soils, shaped by volcanic parent materials and strong environmental gradients, provide a unique setting for discovering functionally diverse fungal strains with distinct metabolic traits.
