Hydrangea macrophylla is a flowering plant that changes color of the bloom in response to soil pH. Ferdoush et al. demonstrate a metaphorical mimicry of such a phenomenon at the level of gene activation, where the activator in budding yeast functionally alternates between coactivators, SAGA and NuA4, in response to inorganic phosphate in the growth medium to promote transcription of a high-affinity inorganic phosphate transporter gene, PHO84.

Genomic Outcomes of Haploid Induction Crosses in Potato (Solanum tuberosum L.) [Genome Integrity and Transmission]

The challenges of breeding autotetraploid potato (Solanum tuberosum) have motivated the development of alternative breeding strategies. A common approach is to obtain uniparental dihaploids from a tetraploid of interest through pollination with S. tuberosum Andigenum Group (formerly S. phureja) cultivars. The mechanism underlying haploid formation of these crosses is unclear, and questions regarding the frequency of paternal DNA transmission remain. Previous reports have described aneuploid and euploid progeny that, in some cases, displayed genetic markers...

Genetic Analysis of the Transition from Wild to Domesticated Cotton (Gossypium hirsutum L.)

The evolution and domestication of cotton is of great interest from both economic and evolutionary standpoints. Although many genetic and genomic resources have been generated for cotton, the genetic underpinnings of the transition from wild to domesticated cotton remain poorly known. Here we generated an intraspecific QTL mapping population specifically targeting domesticated cotton phenotypes. We used 466 F2 individuals derived from an intraspecific cross between the wild Gossypium hirsutum var. yucatanense (TX2094) and the elite...

It was critical that GSA was so willing to put their faith in us. Many people didn’t initially have a lot of confidence that a group of postdocs could organize a new event of this scale.
