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 ...

A recent study has unveiled the genetic blueprint behind flowering time in olive trees, a crucial trait for fruit production that is increasingly under threat from climate change. By analyzing 318 ...

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 ...

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 ...
