Abstract

Quorum sensing comprises the mechanism of communication between numerous bacteria via small signalling molecules, termed autoinducers (AI). Using quorum sensing, bacteria can regulate the expression of multiple genes involved in virulence, toxin production, motility, chemotaxis and biofilm formation, thus contributing to adaptation as well as colonisation. The current understanding of the role of quorum sensing in the lifecycle of Campylobacterales is still incomplete. Campylobacterales belong to the class of Epsilonproteobacteria representing a physiologically and ecologically diverse group of bacteria that are rather distinct from the more commonly studied Proteobacteria, such as Escherichia and Salmonella. This review summarises the recent knowledge on distribution and production of AI molecules, as well as possible quorum sensing dependent regulation in the mostly investigated species within the Campylobacterales group: Campylobacter jejuni and Helicobacter pylori.

Phenotypic variation of weed beet (stalk and root length, root shape, presence of anthocyanin colouring, number of flowers (achenes) in the glomerule), with regard to the BBCH phase and the habitat conditions. ANOVA analysis and three categories of traits monitored. Evaluating demonstrable variability in the framework of the traits category and between localities. Demonstrable effect of locality on the presence of anthocyanin colouring was found, however genetic conditionality cannot be ruled out. For the other phenotypic traits no influence was demonstrated. Anthocyanin colouring and root length show significant variability. The most frequent traits are the stem length (100–130 cm), the pencil-shaped root and 2–3 flowers (achenes) in the glomerule. However, these traits do not necessarily manifest themselves at the same time.

A sclerosis tuberosa a TSC1 vagy a TSC2 gén mutációjára visszavezethető autoszomális domináns betegség, amely tumor képződésre hajlamosít. A betegség klinikai tünetei: nem malignus agyi tuberek, bőr-, szem-, szív- és veserendellenességek. Jelen közleményben a szerzők egy széles fenotípusos variabilitást mutató magyar családot ismertetnek. Elsőként a legtöbb tünetet mutató ötéves kisfiú vizsgálatára került sor, akinél 15 hónapos korában észlelték az első epilepsziás rohamot, a koponya-MR számos intracerebrális meszes gócot igazolt, hipopigmentált foltokon kívül egyéb belszervi és neurológiai tünete nem volt. Az édesanya tünetmentes, az anyai nagybátyja hároméves kora, annak húga 17 éves kora, az anyai nagymama 39 éves kora óta epilepsziás és 52 éves kora óta vesecisztái is vannak. A család molekuláris genetikai vizsgálata a TSC1 gén 20-as exonjában de novo pontmutációt (c.2523 C\>T) igazolt a vizsgált családtagokban. Bár a sclerosis tuberosa patomechanizmusára vonatkozólag egyre több adat áll rendelkezére, mégis keveset tudunk az intra- és interfamiliáris fenotípusos variabilitást befolyásoló genetikai módosító tényezőkről.

The nucleotide sequence of the coat protein (CP) gene and the 3' non-translated region, in relation to aphid transmission of 7 potato tuber necrotic ringspot isolates of Potato virus Y (PVYNTN) were studied. Five isolates originated from different areas of potato fields in Hungary and two German isolates served as controls. A 5' tail of the nucleotide sequences of the CP region and 3' non-translated region (NTR) were determined. Sequence data were sent to the EMBL GeneBank Database. Homology of nucleotide and amino acid sequences were high among the studied PVY isolates. According to the characteristic regions, all isolates belonged to the PVYNTN strain. All of the tested isolates could be transmitted by the aphid Myzus persicae Sulzer to the test plant Nicotiana tabacum L. verifying the wide distribution of tuber necrotic ringspot strain in Hungary. Our data suggest that the high homology found in the CP region of the different isolates, are suitable for development of coat protein mediated resistance against PVY in commercially important host plants like, e.g. potato.

Water deficit is a most limiting factor for wheat in rain-fed agricultural systems worldwide. The effects of drought stress on some root features and yield and yield components in wheat (Trticum aestivum L.) were carried out in a factorial experiment based on completely randomized design, under greenhouse condition. The four experimental irrigation regimes, irrigation after 75% of the water was depleted (control), irrigation after 65% of the water was depleted (mild stress), irrigation after 55% of the water was depleted (moderate stress) and irrigation after 45% of the water was depleted (severe stress) were randomized for the main plots. The subplot treatments included eight wheat genotypes. Results showed that Interaction Drought stress with Variety had significantly affected on Total Root Volume and Dry Matter, Number of Tiller and also Shoot Dry Matter. Value of Total Root Volume and Dry Matter, Shoot Dry Matter and Number of Tiller in irrigated varieties were more than rainfed in whole of Drought stresses. N-87-20 variety had most amounts of Total Root Dry Matter, Total Root Volume (exception of control) in all of stresses and control. Root properties influence on yield and other morphological traits of wheat. Stress intensification increase root growth than plant organ so that wheat root can uptake water from soil to compensate damage caused by stress.
