Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

Pest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

Pest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.

Identification of heat-tolerance QTLs and high-temperature stress-responsive genes through conventional QTL mapping, QTL-seq and RNA-seq in tomato

BMC Plant Biology, 2019
Background High temperature is one of the major abiotic stresses in tomato and greatly reduces fruit yield and quality. Identifying high-temperature stress-responsive (HSR) genes and breeding heat-tolerant varieties is an effective way to address this ...

Experimental dissection of phenotypic variation for quantitative disease resistance in canola (Brassica napus) – Leptosphaeria maculans interactions

Pest Management Science, EarlyView.
This graphical abstract illustrates how quantitative resistance to Leptosphaeria maculans in canola is experimentally estimated through multi‐environment replicated trials measuring crown canker severity. Genotype, environment and pathogen sources feed into phenotyping, followed by variance partitioning using mixed models and beta regression to ...

Introgressed Brassica napus × Sinapis alba enhance resistance to the crucifer flea beetle (Phyllotreta cruciferae)

Pest Management Science, EarlyView.
This study demonstrates that Brassica napus lines with Sinapis alba introgressions enhanced resistance against Phyllotreta cruciferae, resulting in reduced feeding damage and improved seedling physiological performance. The introgressed lines showed strong potential as genetic resources for developing more resilient and sustainable canola varieties ...

Precision-mapping and statistical validation of quantitative trait loci by machine learning

BMC Genetics, 2008
Background We introduce a QTL-mapping algorithm based on Statistical Machine Learning (SML) that is conceptually quite different to existing methods as there is a strong focus on generalisation ability.

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

Molecular mapping of important agro-botanic traits in sesame [PDF]

Electronic Journal of Plant Breeding, 2014
Sesame (Sesamum indicum L.) ((2n=26) is one of the most ancient oilseed crop of the world. The present study was undertaken to develop a molecular map of the important agro-botanic traits in sesame.

Population Differentiation and Polygenic Selection in the Finnish Ayrshire Cows Selected on Genomic Information

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Finnish Ayrshire cattle belong to the Nordic Red breeds. The basis of selection in Nordic Red breeds shifted from traditional pedigree‐based breeding values to genomic breeding values between 2011 and 2014. Joint genetic evaluation and admixture among the Nordic Red breeds have led to the formation of a composite Nordic Red population ...

Evaluating Selection Strategies Based on Inbreeding Load via Simulation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.
