I spent just a couple of days checking out the Death Valley mega-bloom last weekend. It was toward the tail end of the event, but it was spectacular.
The next lab meeting will happen on Wednesday November 5th at noon, Science 3, G17. This week, still in preparation to Dr. Yao-Wu Yuan's visit, another of his papers will be discussed (see link below). I want to know more about the genetic and molecular basis underlying prezygotic barriers to reproduction between the bumblebee-pollinated Mimulus lewisii and the hummingbird-pollinated Mimulus cardinalis. Everyone is invited.
Yuan, Y-W., J. M. Sagawa, R. C. Young, B. J. Christensen, and H. D. Bradshaw Jr. 2013. Genetic dissection of a major anthocyanin QTL contributing to pollinator-mediated reproductive isolation between sister species of Mimulus. Genetics 194:255-263.
Congrats to Avi, Dana, Fuseina, Isaac, and Zara! All five were awarded undergraduate research awards to support the projects they are working on in the lab. Thanks for all your hard work, and congrats on the successful proposals!
Dr. Yaowu Yuan will be visiting us in a couple of weeks, so in preparation, I'd like to read one of his most recent publications on the molecular basis of flower color evolution in Mimulus. We'll discuss this at lab meeting on Wednesday October 29th at noon. It's our Halloween lab meeting, so don't forget to come dressed as your favorite evolutionary geneticist.
This week we're looking over a very-recent article that discusses the evolution of woodiness and perennial life history traits in one such species that diverged from a genus of herbaceous annuals (Helianthus). See you on Wednesday.
Last lab meeting we talked about variation, regulation, and sources of selection on R genes in tomato. Now we’d like to explore models for the evolution of host-pathogen interactions in plants. This week’s paper contrasts two hypotheses about the evolution of R genes, this time in Arabidopsis.
Last week we learned about how incompatibilities may arise due to epistasis between plant immune defense loci known as 'R genes.' We'd like to read more about where variation in R genes comes from, and get more background about what they do for plants. This week's paper looks at a specific R gene family in tomatoes, and makes some hypotheses about sources of selection acting on them.
The Mimulus norrisii plants we started are beginning to flower- now the fun begins!
At long last, some Mimulus are growing in the Binghamton University greenhouses. Three cheers!
And we've only just begun!
Great news! Jay's paper with Grace Chen, entitled "Unification of methods for estimating the strength of reproductive isolation" has been officially accepted for publication in the journal Evolution!
Our lab website is up and running; thanks to Alex Turo for getting the shell in great shape!
