Comparative Transcriptome Analysis to Identify Candidate Genes for Conferring Resistance Against in Cultivated Strawberry ( × ).

crown rot (CCR) caused by is a serious threat to the cultivated strawberry (). Our previous study reported that a major locus, , increases resistance. However, the genomic structure of and potential candidate genes associated with the resistance remained unknown.

FaRCa1: a major subgenome-specific locus conferring resistance to Colletotrichum acutatum in strawberry.

Optimal strategies for genetic improvement in crops depend on accurate assessments of the genetic architecture of traits. The overall objective of the present study was to determine the genetic architecture of anthracnose fruit rot (AFR) resistance caused by the fungus Colletotrichum acutatum in the University of Florida strawberry (Fragaria × ananassa) breeding germplasm. In 2016-2017, 33 full-sib families resulting from crosses between parents with varying levels of AFR resistance were tested.

Clarifying sub-genomic positions of QTLs for flowering habit and fruit quality in U.S. strawberry (×) breeding populations using pedigree-based QTL analysis.

The cultivated strawberry (×) is consumed worldwide for its flavor and nutritional benefits. Genetic analysis of commercially important traits in strawberry are important for the development of breeding methods and tools for this species. Although several quantitative trait loci (QTL) have been previously detected for fruit quality and flowering traits using low-density genetic maps, clarity on the sub-genomic locations of these QTLs was missing.

Genotyping-by-sequencing enables linkage mapping in three octoploid cultivated strawberry families.

Genotyping-by-sequencing (GBS) was used to survey genome-wide single-nucleotide polymorphisms (SNPs) in three biparental strawberry ( × ) populations with the goal of evaluating this technique in a species with a complex octoploid genome. GBS sequence data were aligned to the '' reference genome in order to call SNPs. Numbers of polymorphic SNPs per population ranged from 1,163 to 3,190.

Lung tumor development in the presence of sphingosine 1-phosphate agonist FTY720.

Urethane is a chemical carcinogen which causes lung tumorigenesis in mice with similarities to human adenocarcinoma (AC). The sphingosine 1-phosphate agonist FTY720 administered to mice in doses above 5 mg/kg/day has been able to prevent hepatocellular carcinoma and bladder cancer. We used BALB/c mice in urethane-induced lung cancer model to investigate the effects of a lower dose of FTY720 (1 mg/kg/day).

FTY720 and lung tumor development.

FTY720 has been shown to prevent cancer development in experimental models but there is no report whether this beneficial effect is associated with the time point of the drug administration. Lung adenoma was induced in mice by urethane injection followed by different periods of FTY720 administration in order to evaluate lung tumor development. BALB/c mice received urethane intraperitoneally in two doses of 1.
