Integrating Genomics and Metabolomics to Inform Breeding for Powdery Mildew Resistance in Grapevine
… for over 30% phenotypic variation. Marker haplotypes, hap+chr2 and hap+chr15, were constructed to trace the inheritance of resistance loci in grandparent-parent-progeny relationships. Both hap+chr2 and hap+chr15 in the resistant F1 progeny were inherited from parent MN1264, that originated …

Biopsychosocial Models of the Development of Childhood Disruptive Behaviors
<p>Hyperactivity/attention problems (HAP) and conduct problems (CP) are common and impairing disruptive behaviors in childhood and adolescence. Previous research has established that HAP and CP are highly comorbid, and that outcomes are worse for youth exhibiting both symptom clusters relative to …
