The pathogen genetically transforms host plant cells resulting in tumour growth. Transfer of a bacterial DNA segment (the T-DNA) from the bacterium to the host cell nucleus is mainly guided by bacterial virulence genes, while its integration into the host plant genome is determined by host genes. The ultimate goal of our work was to achieve Agrobacterium-resistance in grapevine by silencing host plant genes contributing to the transformation process. The candidate gene approach was applied to identify genes of interest (GOIs) in grapevine. The selection of GOIs with existing biological evidence for their involvement in the transformation process in model organisms was followed by an in- depth bioinformatic analysis of homologous gene families in grapevine. Selected grape gene families were the subject of gene expression analysis. Based on our results, grape homologues of the GTPase AtRab8, the Vir-interacting protein AtVIP1 and the histone protein AtH2A can be described as responsive to A. tumefaciens inoculation in grapevine. Hairpin-based RNAi silencing constructs selective for these genes have been established and their effect on crown gall tumour formation will be tested on transgenic grapevines.}, year = {2017}, pages = {315-320}, orcid-numbers = {Deák, Tamás/0000-0001-8172-3259; Bisztray, György Dénes/0000-0001-5646-1357} } @article{MTMT:3220097, title = {Establishment of grapevine embryogenic liquid culture and induced somatic embryogenesis}, url = {https://m2.mtmt.hu/api/publication/3220097}, author = {I, Forgács and B, Suller and Zok, Anikó and Pedryc, Andrzej and Oláh, Róbert and Deák, Tamás and Bisztray, György Dénes and Szegedi, Ernő}, doi = {10.17660/ActaHortic.2017.1157.18}, journal-iso = {ACTA HORTICULTURAE}, journal = {ACTA HORTICULTURAE: TECHNICAL COMMUNICATIONS OF ISHS}, volume = {1157}, unique-id = {3220097}, issn = {0567-7572}, abstract = {Somatic embryogenesis is a process in which somatic cells can be used to regenerate embryos and whole plants. Embryogenic cell suspensions of 'Chardonnay' and 'Richter 110' grapevine cultivars were established in 8 different liquid media, cultures had been later maintained in solid media. By the end of the sixth week, we achieved 7-fold increase of fresh weight in the case of the 'Chardonnay' cultivar, using MSM1 and CP2 liquid media. Four different pH values of hormone-free MSM1 media were tested in our experiments (pH 5.8, pH 4.6, pH 4.3 were adjusted before autoclaving; or pH 4.3 after autoclaving). In the case of pH 5.8, we measured a 16-fold increase of fresh weight of the 'Richter110' cultivar. Various culture densities (0.25-4 mg mL-1) were tested, and found that the one with 2 mg mL-1 density was the most efficient. Somatic embryogenesis proved to be significantly more efficient when the medium was supplemented with 0.5 g L-1 MES buffer [2-(N-morpholino) ethanesulfonic acid]. In this case, however, the embryos regenerated developed highly elongated hypocotyls, which inhibited the germination of the embryos as well as the successful regeneration of plants. In a half-strength MSM1 medium with a cell density of 1 mg mL-1, the cultures were composed of well synchronised globular stage embryos. In this setup, however, further differentiation was reversibly inhibited. This inhibition can be resolved by a second dilution of the cultures (to 1 mg mL-1 cell density). When hormone-free MSM1 medium was used after the second dilution, which was enriched with 1 g L-1 activated charcoal, synchronised and well developed cotyledonary stage embryos were differentiated in the liquid cultures by the sixth week.}, year = {2017}, eissn = {2406-6168}, pages = {113-118}, orcid-numbers = {Deák, Tamás/0000-0001-8172-3259; Bisztray, György Dénes/0000-0001-5646-1357} } @article{MTMT:3105151, title = {Evaluation of yarrow (Achillea) accessions by phytochemical and molecular genetic tools}, url = {https://m2.mtmt.hu/api/publication/3105151}, author = {Inotai, Katalin and György, Zsuzsanna and Kindlovits, Sára and Várady, György and Zámboriné Németh, Éva}, doi = {10.5073/JABFQ.2016.089.013}, journal-iso = {J APPL BOT FOOD QUAL}, journal = {JOURNAL OF APPLIED BOTANY AND FOOD QUALITY-ANGEWANDTE BOTANIK}, volume = {89}, unique-id = {3105151}, issn = {1613-9216}, year = {2016}, eissn = {1439-040X}, pages = {105-112}, orcid-numbers = {Várady, György/0000-0003-2012-9680} } @article{MTMT:3105101, title = {Changing of the flower bud frost hardiness in three Hungarian apricot cultivars}, url = {https://m2.mtmt.hu/api/publication/3105101}, author = {Szalay, László and Ladányi, Márta and Hajnal, Veronika and Pedryc, Andrzej and Tóth, Magdolna}, doi = {10.17221/161/2015-HORTSCI}, journal-iso = {HORTIC SCI}, journal = {HORTICULTURAL SCIENCE}, volume = {43}, unique-id = {3105101}, issn = {0862-867X}, year = {2016}, eissn = {1805-9333}, pages = {134-141}, orcid-numbers = {Ladányi, Márta/0000-0003-3114-8289; Tóth, Magdolna/0000-0002-9271-3010} } @article{MTMT:3007802, title = {Rhodiola rosea L.: from golden root to green cell factories}, url = {https://m2.mtmt.hu/api/publication/3007802}, author = {Andrey, S Marchev and Albena, T Dinkova-Kostova and György, Zsuzsanna and Mirmazloum, Iman and Ina, Y Aneva and Milen, I Georgiev}, doi = {10.1007/s11101-016-9453-5}, journal-iso = {PHYTOCHEM REV}, journal = {PHYTOCHEMISTRY REVIEWS}, volume = {15}, unique-id = {3007802}, issn = {1568-7767}, year = {2016}, eissn = {1572-980X}, pages = {515-536}, orcid-numbers = {Mirmazloum, Iman/0000-0002-1461-0382} } @article{MTMT:2808445, title = {Phylogeography of Syringa josikaea (Oleaceae).
