The giant diploid faba genome unlocks variation in a global protein crop

Publisher Copyright: © 2023, The Author(s).Increasing the proportion of locally produced plant protein in currently meat-rich diets could substantially reduce greenhouse gas emissions and loss of biodiversity1. However, plant protein production is hampered by the lack of a cool-season legume equivalent to soybean in agronomic value2. Faba bean (Vicia faba L.) has a high yield potential and is well suited for cultivation in temperate regions, but genomic resources are scarce. Here, we report a high-quality chromosome-scale assembly of the faba bean genome and show that it has expanded to a massive 13 Gb in size through an imbalance between the rates of amplification and elimination of retrotransposons and satellite repeats. Genes and recombination events are evenly dispersed across chromosomes and the gene space is remarkably compact considering the genome size, although with substantial copy number variation driven by tandem duplication. Demonstrating practical application of the genome sequence, we develop a targeted genotyping assay and use high-resolution genome-wide association analysis to dissect the genetic basis of seed size and hilum colour. The resources presented constitute a genomics-based breeding platform for faba bean, enabling breeders and geneticists to accelerate the improvement of sustainable protein production across the Mediterranean, subtropical and northern temperate agroecological zones.Peer reviewe

Development of services in the area of sale of metallurgical material

The thesis deals with the project related to development of services on the market of metallurgical materials. It takes into consideration the possibility of implementation of the project and also proposes concrete actions and solutions. On the one hand it is based on the expert publication and statistical datas, on the other hand on the internal documents of the company XY and the own survey of customer's needs in the area of surface finish and working of steel tubes and hollow profiles. Justifiability of the main idea of the project is supported by four factors. Therefore, development of the market, competition, customer's demands and long-term strategy of involved company XY represent the basis for specifications of final form of the project. On the basis of the assessment of these factors the individual conclusions are worked out. It is case of business plan. Except for analyse of resources, budget and schedule the thesis is focused on the identification of main risks concerning the project. The final outcome of the thesis is represented by concrete proposal of the project

Creation of Competitive Advantage on the Market in Metallurgical Materials

The aim of this bachelor thesis is to evaluate via analysis of chosen factors the posibility of a construction of service centre for Czech and Slovak market. This analysis is made for needs of the company Van Leeuwen Pipe and Tube Group, especially for its branch in the Czech Republic and in Slovakia. By this reason the thesis is divided into theoretical and practical part. While the theoretical part is focused on a presentation of the company Van Leeuwen and for the purpose of understanding of the metallurgical issue also on a characteristic of relevant market, the practical part concerns the analysis of chosen factors with direct impact on a project of service centre. Concretely it's a case of the evaluation of customers' interest in selected service operations and the finding of companies which have already operated in the area of service centre. Last but not least the attention is paid to strategic location of service centre.Cílem této bakalářské práce je prostřednictvím analýzy vybraných faktorů zhodnotit možnost vybudování servisního centra na českém a slovenském trhu s hutními materiály. Tato analýza je prováděna pro potřeby společnosti Van Leeuwen Pipe and Tube Group, především pro její pobočku se zastoupením v České republice a na Slovensku. Z tohoto důvodu je práce rozdělena na část teoretickou a praktickou. Zatímco část teoretická je věnována představení společnosti Van Leeuwen a pro přiblížení problematiky hutních materiálů také charakteristice příslušného trhu se zaměřením na základní deskriptory, praktická část se zabývá analýzou vybraných faktorů s přímým dopadem na možnost realizace projektu servisního centra. Konkrétně se jedná o vyhodnocení zájmu zákazníků o vybrané servisní operace a o vyhledání společností, které již v oblasti servisních center působí. V neposlední řadě je pozornost věnována myšlence strategického umístění servisního centra

Faba bean (Vicia faba L.) has a high yield potential and is well suited for cultivation in temperate regions, but genomic resources are scarce.
