First-generation selection (FGS) and second-generation selection (SGS) breeding populations of loblolly pine from east Texas were studied to estimate the genetic diversity, population structure, linkage disequilibrium (LD), signatures of selection and association of breeding traits with a genome-wide panel of 4,264 single nucleotide polymorphisms (SNPs).(More)
Southern pine cooperative breeding programs currently emphasize genetic improvement of growth rates. When a deployment population, typically a seed orchard, is established, there is an opportunity to emphasize traits other than growth rate to maximize the profit of individual cooperators in the breeding program. We studied a Southeast Texas breeding(More)
Loblolly pine (Pinus taeda L.) is one of the most widely planted and commercially important forest tree species in the USA and worldwide, and is an object of intense genomic research. However, whole genome resequencing in loblolly pine is hampered by its large size and complexity and a lack of a good reference. As a valid and more feasible alternative,(More)
Natural genetic diversity within and among species is the basis of most plant breeding programs. It relies on variation in DNA sequences but also on variability in the presence and absence of genes and regulatory elements, or " structural polymorphisms " (SP). The objectives of this project are to characterize the extent of SP between and within species in(More)
The Western Gulf Forest Tree Improvement Program (WGFTIP) continued to adjust to changing circumstances throughout 2006. The response to 200 hurricanes Katrina and Rita spilt over into 2006 as one or the other of these two storms damaged nearly every orchard complex in the states of Mississippi, Louisiana, and Texas. In the aftermath of the storms,(More)
Erratum The accession number for the sequence submitted to NCBI Sequence Read Archive (SRA) listed in the original article [1] is incorrect; SRP075763 should be SRP075363. Reference 1. Lu M, et al. Exome genotyping, linkage disequilibrium and population structure in loblolly pine (Pinus taeda L. permits unrestricted use, distribution, and reproduction in(More)
Invasive plants decrease biodiversity, modify vegetation structure, and inhibit growth and reproduction of native species. Japanese honeysuckle (Lonicera japonica Thunb.) is the most prevalent invasive vine in the forestlands of eastern Texas. Hence, we aimed to identify potential factors influencing the distribution of the species, quantify the relative(More)
Acoustics have been used to determine wood quality attributes in both standing timber and sawn lumber. Sonic transmission data are collected non-destructively and can act as a surrogate for stiffness, they are directly related to modulus of elasticity (MOE) and closely related to differences in microfibril angle (MFA). Together with wood density, MFA and(More)
