15. Vrednotenje genskih virov navadnega (Phaseolus vulgaris L.) in turškega (Phaseolus coccineus L.) fižola s pomočjo morfometričnih parametrovEva Sinkovič, 2018, magistrsko delo Povzetek: V sklopu magistrskega dela smo v Slovenski rastlinski genski banki Kmetijskega inštituta Slovenije, s pomočjo morfometričnih parametrov ovrednotili zbirki genskih virov navadnega (Phaseolus vulgaris L.) in turškega fižola (Phaseolus coccineus L.). S predpisanimi deskriptorji (UPOV, CPVO, IBPGR, Phaselieu) za semena vrst Phaseolus sp., smo skupno okarakterizirati 953 akcesij navadnega in 47 akcesij turškega fižola. Pri vsaki akcesiji smo na 10 polno razvitih in nepoškodovanih semenih vrednotili 6 kvantitativnih (numeričnih) parametrov: dolžino semena; širino semena; višino semena; razmerje dolžina/višina; razmerje višina/širina; in maso 100 oz. 10 semen. Pri navadnem fižolu smo določili maso na 100, pri turškem pa na 10 semenih. V nadaljevanju smo semena vrednotili z 8 kvalitativnimi (opisnimi) parametri: barva semena; število barv na semenu; primarna barva semena; sekundarna barva semena; razporeditev sekundarne barve na semenu; ožiljenost semena; oblika semena; ter barva in vzorec na plašču semena. Za vsako akcesijo smo posneli vzorčno fotografijo visoke ločljivosti. Na osnovi rezultatov 6 numeričnih parametrov smo za akcesije navadnega fižola pojasnili njihov geografski izvor. Pri vrednotenju turškega fižola, so se akcesije na osnovi 6 numeričnih parametrov najbolj razlikovale v masi 10 semen. Na osnovi rezultatov 8 opisnih parametrov, sta se pri navadnem in turškem fižolu izoblikovali dve skupini. Prva je zajemala akcesije s primarno in sekundarno barvo, druga pa semena le s primarno barvo svetlih ali temnih odtenkov. Na osnovi vseh 14 morfometričnih parametrov, sta se pri obeh zbirkah genskih virov fižola izoblikovali dve skupini. Prva skupina je zajemala akcesije Andskega in druga Srednje Ameriškega izvora.

18. The Carniolan honeybee from Slovenia : a complete and annotated mitochondrial genome with comparisons to closely related Apis mellifera subspeciesAjda Moškrič, Andraž Marinč, Polonca Ferk, Branimir Leskošek, Mai-Britt Mosbech, Ignas Bunikis, Olga Vinnere Pettersson, Lucile Soler, Janez Prešern, izvirni znanstveni članek Povzetek: The complete mitochondrial genome of the Carniolan honeybee (Apis mellifera carnica) from Slovenia, a homeland of this subspecies, was acquired in two contigs from WGS data and annotated. The newly obtained mitochondrial genome is a circular closed loop of 16,447 bp. It comprises 37 genes (13 protein coding genes, 22 tRNA genes, and 2 rRNA genes) and an AT-rich control region. The order of the tRNA genes resembles the order characteristic of A. mellifera. The mitogenomic sequence of A. m. carnica from Slovenia contains 44 uniquely coded sites in comparison to the closely related subspecies A. m. ligustica and to A. m. carnica from Austria. Furthermore, 24 differences were recognised in comparison between A. m. carnica and A. m. ligustica subspecies. Among them, there are three SNPs that affect translation in the nd2, nd4, and cox2 genes, respectively. The phylogenetic placement of A. m. carnica from Slovenia within C lineage deviates from the expected position and changes the perspective on relationship between C and O lineages. The results of this study represent a valuable addition to the information available in the phylogenomic studies of A. mellifera—a pollinator species of worldwide importance. Such genomic information is essential for this local subspecies’ conservation and preservation as well as its breeding and selection.

20. Combined effects of early season leaf removal and climatic conditions on aroma precursors in Sauvignon blanc grapesPaolo Sivilotti, Branka Škvarč, Lorena Butinar, Melita Sternad Lemut, Klemen Lisjak, Andreja Vanzo, 2017, izvirni znanstveni članek Povzetek: Early leaf removal around the cluster zone is a common technique applied in cool climate viticulture, to regulate yield components and improve fruit quality. Despite the increasing amount of information on early leaf removal and its impact on total soluble solids, anthocyanins and polyphenols, less is known regarding aroma compounds. In order to verify the hypothesis that defoliation, applied before or after flowering, could impact the biosynthesis of thiol precursors, we performed a two year (2013 and 2014) experiment on Sauvignon blanc. We provided evidence that differential accumulation of thiols precursors in berries is affected by the timing of defoliation and this impact was related to modifications in biosynthetic pathway. Furthermore, the possible interaction between leaf removal treatment and seasonal weather conditions, and its effect on the biosynthesis of volatile precursors are discussed. Our results suggested that in Sauvignon blanc the relative proportion of 4-S-glutathionyl-4-methylpentan-2-one (G-4MSP) and 3-S-glutathionylhexan-1-ol (G-3SH) precursors can be affected by defoliation, and this could be related to the induction of two specific genes encoding glutathione-S-transferases (VvGST3 and VvGST5), while no significant effects on basic fruit chemical parameters, polyphenols and methoxypyrazines were ascertained under our experimental conditions.
