Introduction

Almeria, the leading European region in terms of fruits and vegetable production and exportation, is emerging as a prominent innovation hub for greenhouse technology and production. In the field of plant breeding, Almería concentrates a significant portion of the total horticulture seed business activity among the world. Indeed, the most notable Spanish and international companies are based in Almeria, producing novel horticultural varieties through intensive research and development programs. These novel varieties ”made in Almeria” are not only used in this Spanish region but also exported and cultivated in many different greenhouses all over the world. The area of Genetics at the University of Almería is in close collaboration with the seed companies and the productive system of Almería. More precisely, the HORTICULTURAL GENETICS research group accumulates more than 25 years of experience focusing on research and teaching activities in the field of plant biotechnology and breeding. The goal of the present course is to share our theoretical and practical knowledge regarding the biotechnology methods and tools widely used in horticultural crops breeding and production. To do so, our multidisciplinary group encompass the fields of genetics, plant physiology, plant production and food technology allowing us to perform high-throughput plant phenotyping for abiotic and biotic stress tolerance, nutrients, drought and salinity tolerance, and postharvest fruit quality. The phenomics studies are followed by molecular studies through high-throughput genotyping using next-generation sequencing (NGS) technologies and bioinformatics analysis in order to identify plant materials, molecular markers and genes useful for developing novel cultivars in horticultural crops.

Objectives

  1. To study the productive system and business model of Almería linked to vegetable breeding programs, throughout site visits to seed companies, seedbeds, field varietal assays, and packing and exportation companies of fresh F&V.
  2. To teach widely used biotechnology tools employed in vegetable breeding programs, including those focused on postharvest fruit quality, and tolerance to different conditions such as abiotic, nutrition, drought, and biotic stresses.
  3. To obtain hands-on experience in phenomics, genomics and bioinformatics tools applied to plant breeding by means of laboratory practices and bioinformatics analyses.

  • Practice: genotyping of segregating populations using Taq-man probes.
  • Lecture: Bioinformatics pipelines for the analysis of RNA-seq data in the model and non-model plants.
  • Practice: Design of a bioinformatics pipeline for the analysis of RNA-seq data: quality filtering, trimming, mapping and differential gene expression. Visualization and interpretation of the obtained results.

Methodology

The course has a very important practical component. In each module, the professor will explain the theoretical basis and the design of the experiments that will be developed in the practical sessions. In the field trials, students will learn to identify and select agronomic interesting traits, laboratory experiments will improve student skills for the chemical and physical screening of plants, as well as high-throughput plant genotyping. In computer-assisted classes, students will understand the bioinformatic tools for SNPs and mutations identification, QTL analysis, and gene expression studies by using RNAseq.
