American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

A Chromosomal Region Promoting Outcrossing in a Conifer
Genetics, 2001 AbstractPrefertilization mechanisms influencing selfing rates are thought to be absent in conifers. Outcrossing in conifers is promoted via an embryo-lethal system, but the genetic mechanism is poorly understood. This study is the first experimental profile of the genetic mechanism promoting outcrossing in conifers.

Natural outcrossing in grasspea [PDF]
, 1996 Non-Peer ReviewedThe outcrossing rate of a species is important in designing experiments for inheritance and linkage studies and selection of appropriate breeding methods for crop improvement. Though predominantly self pollinated, frequent heterozygosity

Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle
Developmental Dynamics, EarlyView.Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

Estimates of outcrossing rates in Lathyrus latifolius populations
, 1991 Isozyme markers were used to estimate parameters of the mating system of Lathyrus latifolius, a bumblebee-pollinated legume. Multilocus outcrossing estimates (mean tm = 0.807; range = 0.702–0.870) differed significantly from random outcrossing ...

Developmental Dynamics, EarlyView.Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Multilocus genomics of outcrossing plant populations
Theoretical Population Biology, 2009 The structure and organization of natural plant populations can be understood by estimating the genetic parameters related to mating behavior, recombination frequency, and gene associations with DNA-based markers typed throughout the genome. We developed a statistical and computational model for estimating and testing these parameters from multilocus ...

Native grass breeding: Priority needs and strategic approaches
Grassland Research, EarlyView.The key needs and breeding strategies of native grass. Abstract Native grasses possess extensive ecological adaptability, such as cold, drought, and salt tolerance, and tolerance to poor soil conditions. They play a crucial role in ensuring food security and ecological security.
