Dear all,
Recently, I received an email from Andrew Groover(Research Geneticist.
US Forest Service. Davis CA) asking for assistance in obtaining
germplasm for a new project. Andrew will be glad to provide more
information if anyone of you is interested in the project. Below, I am
forwarding you Andrew's message. Thank you very much for your help.
Sincerely,

Dear Colleague,
As part of a new project funded by the US Department of Energy, we are
examining the role of ploidy changes in developing superior hybrid
poplar for bioenergy production. We are currently seeking to establish
the frequency of triploidy and aneuploidy in F1 interspecific hybrids in
traditional breeding programs. We are writing to ask if you can provide
us a small amount of leaf tissue (less than 0.5g) from F1 individuals
from any of the species combinations listed below. Ideally, we would
like to have between as few as 6 and as many as 24 F1s from each full
sib family, and if available tissue from the parents. We can process up
to 20 families from your collections. Trees for which some phenotypic
information is available would be highest priority, as would be trees
that you suspect might be triploid/aneuploid (based on growth phenotype
or sterility).
For the tissue we receive from you, we will use low-coverage “next
generation” sequencing to develop a molecular karyotype for each
individual. We will make the karyotype as well as SNP marker genotypes
available to you for the submitted samples. If you wish, you may code
the identities of the samples but we do need to know the relationships
among samples (i.e. which samples are from the same family and which
samples are from parents vs F1s).
If you are interested in participating in the project, please contact
Andrew Groover (agroover(a)fs.fed.us <mailto:agroover@fs.fed.us>
530-759-1738). We will establish with you what genotypes should be
sequenced, and provide you with collection instructions and vials, and a
shipping account. We very much appreciate your assistance.
Sincerely,
Luca Comai and Isabelle Henry (UC Davis)
