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.

GSA conferences foster collaboration, resource development, and the spread of technology and ideas.


Our peer-reviewed journals GENETICS and G3: Genes|Genomes|Genetics publish high-quality, original genetics research across the breadth of the field.

Career Development

GSA professional development programs provide rich opportunities for scientists to gain skills and experience.

Nominate your colleagues.

Shine a light on the best of the genetics community by nominating outstanding colleagues for the 2020 Genetics Society of America Awards. Nominations are open for the Thomas Hunt Morgan Medal, the GSA Medal, the George W. Beadle Award, the Elizabeth W. Jones Award for Excellence in Education, and the Edward Novitski Prize. Nominations are due by October 3, 2019.

Hybrid Decay: A Transgenerational Epigenetic Decline in Vigor and Viability Triggered in Backcross Populations of Teosinte with Maize [Gene Expression]

In the course of generating populations of maize with teosinte chromosomal introgressions, an unusual sickly plant phenotype was noted in individuals from crosses with two teosinte accessions collected near Valle de Bravo, Mexico. The plants of these Bravo teosinte accessions appear phenotypically normal themselves and the F1 plants appear similar to typical maize x teosinte F1s. However, upon backcrossing to maize, the BC1 and subsequent generations display a number of detrimental characteristics including shorter stature,...

Genome-Wide Association Analysis for Resistance to Infectious Pancreatic Necrosis Virus Identifies Candidate Genes Involved in Viral Replication and Immune Response in Rainbow Trout (Oncorhynchus mykiss)

Infectious pancreatic necrosis (IPN) is a viral disease with considerable negative impact on the rainbow trout (Oncorhynchus mykiss) aquaculture industry. The aim of the present work was to detect genomic regions that explain resistance to infectious pancreatic necrosis virus (IPNV) in rainbow trout. A total of 2,278 fish from 58 full-sib families were challenged with IPNV and 768 individuals were genotyped (488 resistant and 280 susceptible), using a 57K SNP panel Axiom, Affymetrix. A genome-wide...

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.
