The Importance and Practice of Selection Breeding in Walnut

In Turkey, the predominant method of walnut breeding is selection breeding which is the selection of elite genotypes as practiced worldwide. Due to this reason, the method of selecting elite genotypes with the desired agronomic characteristics is a short span and easily practicable. In countries, where the population of walnut is at low scale, hybridization practices are not attempted to acquire desired agronomic characteristics. The hybridization practices are time consuming to get the target genotypes. The walnut varieties improvement programs should include the priority issues such as: late leaf foliage, fruiting in lateral branches, shortening of the vegetation period, early maturity and harvesting, good fruit quality, high yield and resistance to diseases

Revisiting the complex architecture of ALS in Turkey: Expanding genotypes, shared phenotypes, molecular networks, and a public variant database

The last decade has proven that amyotrophic lateral sclerosis (ALS) is clinically and genetically heterogeneous, and that the genetic component in sporadic cases might be stronger than expected. This study investigates 1,200 patients to revisit ALS in the ethnically heterogeneous yet inbred Turkish population. Familial ALS (fALS) accounts for 20% of our cases. The rates of consanguinity are 30% in fALS and 23% in sporadic ALS (sALS). Major ALS genes explained the disease cause in only 35% of fALS, as compared with similar to 70% in Europe and North America. Whole exome sequencing resulted in a discovery rate of 42% (53/127). Whole genome analyses in 623 sALS cases and 142 population controls, sequenced within Project MinE, revealed well-established fALS gene variants, solidifying the concept of incomplete penetrance in ALS. Genome-wide association studies (GWAS) with whole genome sequencing data did not indicate a new risk locus. Coupling GWAS with a coexpression network of disease-associated candidates, points to a significant enrichment for cell cycle- and division-related genes. Within this network, literature text-mining highlightsDECR1, ATL1, HDAC2, GEMIN4, andHNRNPA3as important genes. Finally, information on ALS-related gene variants in the Turkish cohort sequenced within Project MinE was compiled in the GeNDAL variant browser (www.gendal.org).Bogazici University; Suna and Inan Kirac Foundatio
