UC Davis graduate student Jeffrey Groh has discovered how walnut trees are able to produce flowers of different sexes at different times in the same season. The genetic mechanism is similar to sex ...

Projection of the 318 genotypes from WOGBM on the first two principal components (PC) of a PC analysis based on 235 825 SNPs. Colors blue, green, and orange indicate the group to which each genotype ...

Botanists have mapped the evolutionary relationships between flowering plants using genomic data from more than 9500 species. The newly compiled tree of life will help scientists piece together the ...

Researchers at Penn State studying declining populations of sundial lupines in the eastern part of the United States are closer to determining how the plant's genetics could be used to inform ...

An international research team led by the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) has discovered a gene mutation (PPD-H1) that causes barley to flower later in regions with ...

Flower development and sex determination in cucurbits represent a finely tuned interplay between hormonal regulation, transcriptional networks and genetic diversity. Ethylene emerges as a pivotal ...

For flowering plants, attracting the right pollinator can be a matter of survival – and new research shows how they do it is very intriguing.

UC Davis scientists discovered how walnut trees switch between male and female flowering, a trait that’s been stable for 40 million years. The trees’ “sex timing” depends on two ancient gene variants ...
