THE ALMOND GENOME: MUTATION OF A BHLH TRANSCRIPTION FACTOR AS BASIS FOR DOMESTICATION (Keynote speaker).
Dr. Sánchez Pérez received her PhD degree in Biochemistry at the University of Murcia (Spain) in 2006, followed by a postdoctoral stay at Plant Biochemistry Lab (University of Copenhagen), where she finally became Associate Professor. In 2017, she got the most prestigious contract in Spain called “Ramón y Cajal” as a senior scientist, to work at the Plant Breeding Department at CEBAS-CSIC. Her main research consists on the study of important agronomic traits, such as bitterness (P450 enzymes, UGTs, bHLHs), dormancy and flowering time (DAMs, FLC, FT), within Prunus species (i.e. almond, apricot and cherry) to develop molecular markers that will help breeders to obtain new varieties in a climate change context. She is very grateful for the support received by Seneca Foundation (Murcia), VILLUM Foundation (Denmark), CSIC, and Spanish Ministry of Science.

Almond [Prunus dulcis Miller (DA Webb)] is the main tree nut species worldwide. Here, genotyping-by-sequencing (GBS) was applied to 149 almond cultivars from the ex situ collections of the Italian Council for Agricultural Research (CREA) and the Spanish National Research Council (CSIC), leading to the detection of 93,119 single-nucleotide polymorphisms (SNPs). The study of population structure outlined four distinct genetic groups and highlighted diversification between the Mediterranean and Californian gene pools. Data on SNP diversity and runs of homozygosity (ROHs) allowed the definition of kinship, inbreeding, and linkage disequilibrium (LD) decay in almond cultivated germplasm. Four-year phenotypic observations, gathered on 98 cultivars of the CREA collection, were used to perform a genome-wide association study (GWAS) and, for the first time in a crop species, homozygosity mapping (HM …
