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.

Career Development

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

Register for TAGC Online Workshops.

Sign up for a free TAGC Online workshop! These two-hour interactive events are organized by the GSA community and feature a range of scientific and professional development topics. The signup form for each workshop will be available at the link below one week before it is scheduled to be held.

Keep up with the latest research.

Hosted by the Steering Committee of GSA’s Early Career Leadership Program, the “Science in a Snapshot” online seminar series is designed to showcase research by student and postdoc GSA members. Each month, two presenters discuss their work in an 8–10-minute talk, followed by lively Q&A sessions.

Pits and CtBP Control Tissue Growth in Drosophila melanogaster with the Hippo Pathway Transcription Repressor Tgi [Developmental and Behavioral Genetics]

The Hippo pathway is an evolutionarily conserved signaling network that regulates organ size, cell fate, and tumorigenesis. In the context of organ size control, the pathway incorporates a large variety of cellular cues, such as cell polarity and adhesion, into an integrated transcriptional response. The central Hippo signaling effector is the transcriptional coactivator Yorkie, which controls gene expression in partnership with different transcription factors, most notably Scalloped. When it is not activated by Yorkie, Scalloped...

A Genome-Wide Association Study To Understand the Effect of Fusarium verticillioides Infection on Seedlings of a Maize Diversity Panel

Fusarium verticillioides, which causes ear, kernel and stem rots, has been reported as the most prevalent species on maize worldwide. Kernel infection by F. verticillioides results in reduced seed yield and quality as well as fumonisin contamination, and may affect seedling traits like germination rate, entire plant seedling length and weight. Maize resistance to Fusarium is a quantitative and complex trait controlled by numerous genes with small effects. In the present work, 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.
