Grovesiella abieticola (Tympanidaceae): an Unrecorded Endophytic Fungus from South Korea

open access: yes한국균학회지, 2020
We report on an unrecorded endophytic fungus, Grovesiella abieticola (Zeller & Goodd.) M. Morelet & Gremmen isolated from Abies koreana of Mt. Halla in Jeju.

Commuting to Work: Nucleolar Long Non-Coding RNA Control Ribosome Biogenesis from Near and Far

open access: yesNon-Coding RNA, 2021
Gene expression is an essential process for cellular growth, proliferation, and differentiation. The transcription of protein-coding genes and non-coding loci depends on RNA polymerases.

Transcription of spacer sequences flanking the rat 45S ribosomal DNA gene. [PDF]

open access: yesMolecular and Cellular Biology, 1987
The transcriptional activity of spacer sequences flanking the rat 45S ribosomal DNA (rDNA) gene were studied. Nascent RNA labeled in in vitro nuclear run-on reactions hybridized with both 5' and 3' spacer regions. The highest level of hybridization was seen with an rDNA fragment containing tandem repeats of a 130-base-pair sequence upstream of the 45S ...

Sequence Analysis of the Internal Transcribed Spacer of Ribosomal DNA in the GenusRhizopus [PDF]

open access: yesMycobiology, 2005
The internal transcribed spacer (ITS) regions including the 3'-end of 18S rRNA gene, 5.8S rRNA gene and the 5'-end of the 28S rRNA gene of Rhizopus spp. were amplified by PCR and analyzed by DNASIS program. Length polymorphism of these region ranged from 564 bp in R. oryzae to 789bp in R. stolonifer.

Michaelmoelleria (Gesneriaceae), a new lithophilous dwelling genus and species with zigzag corolla tube from southern Vietnam [PDF]

open access: yesPhytoKeys, 2020
Michaelmoelleria, a new genus from southern Vietnam is described with a single species, M. vietnamensis. The new genus is morphologically most similar to Deinostigma and Tribounia but it differs from the latter two by having four fertile stamens. Nuclear

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Reticulation within Sporobolus: recognition of two new sections, Acinifolii and Thellungia, and a new genus, Hyalolemma (Poaceae, Chloridoideae, Zoysieae, Sporobolinae) [PDF]

open access: yesPhytoKeys
We present a molecular DNA phylogeny utilizing four plastid regions (rps16–trnK spacer, rps16 intron, rpl32–trnL spacer, ndhA intron) and the nuclear ribosomal internal transcribed spacer (ITS) region, investigating 123 species of subtribe Sporobolinae ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Identification of Xiphinema vuittenezi by polymerase chain reaction

open access: yesPlant Protection Science, 2004
So far, the identification of the nematode species Xiphinema vuittenezi relied mainly on time-consuming morphological and morphometrical studies.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
