Whether ZFP3 and related ZFP factors regulate plant development is, however, not known.Results ZFP3 overexpression reduced plant growth, limited cell expansion in leaves, and compromised root hair development. The T-DNA insertion zfp3 mutant and transgenic lines with silenced ZFP1, ZFP3, ZFP4, and ZFP7 genes were similar to wild-type plants or had only minor differences in plant growth and morphology, probably due to functional redundancy. RNAseq transcript profiling identified ZFP3-controlled gene sets, including targets of ABA signaling with reduced transcript abundance. The largest gene set that was downregulated by ZFP3 encoded regulatory and structural proteins in cell wall biogenesis, cell differentiation, and root hair formation. Chromatin immunoprecipitation confirmed ZFP3 binding to several target promoters.Discussion Our results suggest that ZFP3 and related ZnF proteins can modulate cellular differentiation and plant vegetative development by regulating the expression of genes implicated in cell wall biogenesis.}, keywords = {EXPRESSION; GENE; INHIBITION; TRANSCRIPTION FACTOR; ABSCISIC-ACID; PLANT DEVELOPMENT; Overexpression; gene silencing; gene overexpression; Arabidopsis thaliana; root hair; gibberellin; trichome initiation; zinc finger protein 3; ZFP5}, year = {2024}, eissn = {1664-462X}, orcid-numbers = {Benyó, Dániel/0000-0002-4537-2866; Zsigmond, Laura/0000-0002-1388-1762} } @inproceedings{MTMT:34493120, title = {Honfoglalás kori köznépi temetők anyai vonalainak jellemzése, archeogenetikai módszerekkel}, url = {https://m2.mtmt.hu/api/publication/34493120}, author = {Maár, Kitti and Neparáczki, Endre and Varga, Gergely István and Kovács, Bence and Maróti, Zoltán and Kalmár, Tibor and Nagy, István and Latinovics, Dóra and Tihanyi, Balázs and Marcsik, Antónia and Kustár, Ágnes and Pálfi, György and Raskó, István and Török, Tibor}, booktitle = {"Hadak útján" A népvándorláskor fiatal kutatóinak XXIX. konferenciája. = 29th Conference of scholars on the Migration Period}, doi = {10.55722/Arpad.Kiad.2023.4.2_07}, unique-id = {34493120}, abstract = {A régészeti leletekből kinyerhető archaikus DNS vizsgálata fényt deríthet egyének, populációk eredetére és rokoni kapcsolataira.

A karosi és kenézlői temető együttesek nagy felbontású teljes mitogenom analízise azt mutatta, hogy a honfoglalók anyai ágú vonalai visszavezethetők az eurázsiai sztyeppe távoli részeire: harmaduk Közép-Belső Ázsia területéről származott, kétharmaduk pedig a bronzkori pontusi-kaszpi sztyeppe Poltavka-Potakovka-Szrubnaja kultúráira vezethető vissza. Felvetődött a kérdés, hogy ezek az adatok milyen mértékben vonatkoztathatók a teljes honfoglaló populációra? Hogy ezt a kérdést megválaszoljuk, vizsgálatainkat kiterjesztettük a 10. századi nagyobb sírszámú falusi temetőkre, melyek a honfoglalás kori köznépet rejthetik. A kiválasztott 6 falusi temető mindegyikéből 20-30 egyén anyai vonalait vizsgáltuk. A mintaválasztást elsősorban régészeti és antropológiai adatok alapján végeztük. Mivel a temetők többsége átnyúlik az Árpád-korba és korábbi antropológiai vizsgálatok több temetőben lehetséges népességcserét jeleztek, ezért a korai és a későbbi sírok összehasonlításával a népességcsere kérdésére is választ remélhetünk.

In these approaches, successes are largely dependent on the efficiency of the delivery of gene editing components into plant cells. Here, we report the optimization of the cationic polymer poly(2-hydroxypropylene imine) (PHPI)-mediated delivery of plasmid DNAs, or single-stranded oligonucleotides labelled with Cyanine3 (Cy3) or 6-Carboxyfluorescein (6-FAM)-fluorescent dyes into maize protoplasts. Co-delivery of the GFP-expressing plasmid and the Cy3-conjugated oligonucleotides has resulted in the cytoplasmic and nuclear accumulation of the green fluorescent protein and a preferential nuclear localization of oligonucleotides. We show the application of nanoparticle complexes, i.e., “polyplexes” that comprise cationic polymers and nucleic acids, for CRISPR/Cas9 editing of maize cells. Knocking out the functional EGFP gene in transgenic maize protoplasts was achieved through the co-delivery of plasmids encoding components of the editing factors Cas9 (pFGC-pcoCas9) and gRNA (pZmU3-gRNA) after complexing with a cationic polymer (PHPI). Several edited microcalli were identified based on the lack of a GFP fluorescence signal. Multi-base and single-base deletions in the EGFP gene were confirmed using Sanger sequencing.

However, no quantifiable evaluation of SLST versus MLST for differentiation of C. acnes strains, especially in relation to the subspecies of the bacterium, known as C. acnes subsp. acnes (type I), C. acnes subsp. defendens (type II) and C. acnes subsp. elongatum (type III), has been performed which is vital given its increasing use. To address this, we examined the discriminatory power of SLST versus MLST with a large group of isolates representative of all subspecies. Methods: Simpson's index of diversity (D) was used for quantitative comparison of the resolving power of the SLST and MLST schemes for 186 isolates of C. acnes covering all three subspecies. Results: When strains were considered collectively, SLST and all three MLST approaches had similar D values > 90%. However, at the subspecies level there were significant differences between the methods, most strikingly a reduced discrimination of type II and type III strains (D <80%) by SLST versus MLST8, and to a lesser extent MLST4. The MLST9 method also performed poorly for type II strains (D <70%), but did display the best results for type I (D= 90%). By combining the SLST locus with the camp2 gene sequence to create a novel and flexible high-resolution Bilocus Sequence Typing (BLST) scheme, known as CUTIS-SEQ typing (CUTIbacterium acneS BilocuS sEQuence Typing), we achieved improved resolution at both species and, critically, subspp. levels. Conclusions: CUTIS-SEQ provides an opportunity to improve differentiation of C. acnes isolates by SLST without significantly impacting laboratory workload, or compromising application to complex biological communities.

However, it is unclear how these trade-offs could be utilized for manipulating antibiotic resistance in the clinic, not least because the underlying molecular mechanisms are poorly understood. Using laboratory evolution, we demonstrate that clinically relevant resistance mutations in Escherichia coli constitutively rewire a large fraction of the transcriptome in a repeatable and stereotypic manner. Strikingly, lineages adapted to functionally distinct antibiotics and having no resistance mutations in common show a wide range of parallel gene expression changes that alter oxidative stress response, iron homeostasis, and the composition of the bacterial outer membrane and cell surface. These common physiological alterations are associated with changes in cell morphology and enhanced sensitivity to antimicrobial peptides. Finally, the constitutive transcriptomic changes induced by resistance mutations are largely distinct from those induced by antibiotic stresses in the wild-type. This indicates a limited role for genetic assimilation of the induced antibiotic stress response during resistance evolution.

There is a growing evidence that miRNAs have important roles in pathological processes, such as inflammation or carcinogenesis. Understanding the molecular mechanisms such as alterations in microRNAome upon chronic intestinal inflammation is critical for understanding the exact pathomechanism of IBD. Hence, we conducted a genome wide microRNAome analysis by applying miRNA-Seq in a rat model of experimental colitis, validated the data by QPCR, examined the expression of a selection of precursor and mature miRNAs, performed in depth biological interpretation using Ingenuity Pathway Analysis and tested the obtained results on samples derived from human patients. We identified specific, interdependent expression pattern of activator/repressor transcription factors, miRNAs and their direct targets in the inflamed colon samples. Particularly, decreased expression of the miR-200 family members (miR-200a/b/c,-141, and -429) and miR-27b correlates with the reduced level of their enhancers (HNF1B, E2F1), elevated expression of their repressors (ZEB2, NFKB1) and increased expression of their target genes (ZEB2, RUNX1). Moreover, the marked upregulation of six miR-27b target genes (IFI16, GCA, CYP1B1, RUNX1, MEF2C and MMP13) in the inflamed colon tissues is a possible direct consequence of the lack of repression due to the downregulated miRNA-27b expression.

Recently, hundreds of ancient genomes were analyzed from Central Asia, Mongolia, and China, from which we aimed to identify putative source populations for the above-mentioned groups. In this study, we have sequenced 9 Hun, 143 Avar, and 113 Hungarian conquest period samples and identified three core populations, representing immigrants from each period with no recent European ancestry. Our results reveal that this “immigrant core” of both Huns and Avars likely originated in present day Mongolia, and their origin can be traced back to Xiongnus (Asian Huns), as suggested by several historians. On the other hand, the “immigrant core” of the conquering Hungarians derived from an earlier admixture of Mansis, early Sarmatians, and descendants of late Xiongnus. We have also shown that a common “proto-Ugric” gene pool appeared in the Bronze Age from the admixture of Mezhovskaya and Nganasan people, supporting genetic and linguistic data.
