Journal Article
Kwong, Q. B., Teh, C. K., Ong, A. L., Chew, F. T., Mayes, S., Kulaveerasingam, H., …Harikrishna, J. A. (2017). Evaluation of methods and marker systems in genomic selection of oil palm (Elaeis guineensis Jacq.). BMC Genetics, 18(1), https://doi.org/10.1186/s12863-017-0576-5

Background

Genomic selection (GS) uses genome-wide markers as an attempt to accelerate genetic gain in breeding programs of both animals and plants. This approach is particularly useful for perennial crops such as oil palm, which have long breedin...

Oil palm (Elaeis guineensis Jacq.) is an outbreeding perennial tree crop with long breeding cycles, typically 12 years. Molecular marker technologies can greatly improve the breeding efficiency of oil palm. This study reports the first use of the DAr...

Microsatellite analysis of populations of the endangered tree Gomortega keule suggests pre-Columbian differentiation (2017)
Journal Article
Munoz-Concha, D., Davey, M. R., Ribas, G., & Mayes, S. (in press). Microsatellite analysis of populations of the endangered tree Gomortega keule suggests pre-Columbian differentiation. New Zealand Journal of Botany, 55(3), https://doi.org/10.1080/0028825X.2017.1343737

Temperate forests have been affected extensively by human activities, resulting in land cover changes and population fragmentation. However, these anthropogenic effects can be superimposed onto the natural history of species, making it difficult to d...

Differential gene expression at different stages of mesocarp development in high- and low-yielding oil palm (2017)
Journal Article
Wong, Y. C., Teh, H. F., Mebus, K., Ooi, T. E. K., Kwong, Q. B., Koo, K. L., …Kulaveerasingam, H. (2017). Differential gene expression at different stages of mesocarp development in high- and low-yielding oil palm. BMC Genomics, 18(1), Article 470. https://doi.org/10.1186/s12864-017-3855-7

Background

The oil yield trait of oil palm is expected to involve multiple genes, environmental influences and interactions. Many of the underlying mechanisms that contribute to oil yield are still poorly understood. In this study, we used a micro...

Characterizing haploinsufficiency of SHELL gene to improve fruit form prediction in introgressive hybrids of oil palm (2017)
Journal Article
Teh, C. K., Muaz, S. D., Tangaya, P., Fong, P.-Y., Ong, A. L., Mayes, S., …Appleton, D. R. (in press). Characterizing haploinsufficiency of SHELL gene to improve fruit form prediction in introgressive hybrids of oil palm. Scientific Reports, 7(1), https://doi.org/10.1038/s41598-017-03225-7

The fundamental trait in selective breeding of oil palm (Eleais guineensis Jacq.) is the shell thickness surrounding the kernel. The monogenic shell thickness is inversely correlated to mesocarp thickness, where the crude palm oil accumulates. Commer...

Bambara groundnut (Vigna subterranea (L.) Verdc.) is an underutilised legume crop, which has long been recognised as a protein-rich and drought-tolerant crop, used extensively in Sub-Saharan Africa. The aim of the study was to identify quantitative t... Read More about A cross-species gene expression marker-based genetic map and QTL analysis in bambara groundnut.

Identifying seedling root architectural traits associated with yield and yield components in wheat (2017)
Journal Article
