Optimizing protocol for a rapid and cost effective DNA isolation for Marker Assisted Selection pipeline

Abstract

Grapevine is a plant that holds significant socioeconomic importance due to its production of grapes for fresh consumption, wines, and juices. However, climate changes and susceptibility to diseases pose a threat to the quality and yield of these products. The breeding of new genotypes that are resistant/tolerant to biotic and abiotic stresses is essential to overcome the impact of climate changes. In this regard, Marker-assisted selection (MAS), which uses DNA markers, is a crucial tool in breeding programs. The efficiency and economy of this method depend on finding rapid DNA isolation methods. In this study, we compared four different DNA extraction methods to choose the one that quickly isolates DNA from many young vine leaves samples in a single run. The methods used involved Lithium chloride, carboxyl coated magnetic beads, cetyltrimethylammonium bromide (CTAB), and a commercial kit called Red&extract. The results showed that the CTAB method was the best in terms of reliability of the procedure, yield of the extracted DNA, low quantity of inhibitors, and speed of the procedure. Improving the MAS technique will help identify plants containing genes involved in different types of stress and deepen the study of the resistance genes pyramided.

Coming of age: do old vines actually produce berries with higher enological potential than young vines? A case study on the Riesling cultivar

Consumers and the wine industry tend to agree on the ability of old vines to produce fruit that allows the production of wine of superior character. However, despite past and ongoing research, objective evidence of this point of view is still debated and studies on robust, specifically dedicated plots are scarce. Thus the impact of grapevine age on berry oenological potential and wine quality remains an open question. To try to objectively address the issue, a unique vineyard was established at Geisenheim University, Germany. It was planted in 1971 with cv. Riesling grafted on 5C Teleki. In 1995 and 2012, several rows were uprooted and replanted with the same rootstock/scion combination, resulting in a vineyard with alternate rows of identical plant material, but with different planting dates. The parameters of technical maturity and grape composition at harvest were analyzed during seasons 2014, 2015, 2016 and 2017 combining HPLC and enzymatic methods. Separate micro-vinifications were made for each age group and wine composition was analyzed by a combination of 1H-NMR and SPE-GC-MS.
