Hi everyone,
This is my first time in this area of research. I am working on 95 varieties of bambara groundnut. I have done the agromorphological characterization of these varieties as well as the genetic diversity using DArT markers. Based on the charaterization result, i have selected 10 varieties to be subjected to water stress with the objective of identifying genes that are responsible for tolerance in this plant. My challenge now is:
1. bambara groundnut does not have a reference genome, so will i be able to use GWAS in getting these genes from the result of the DArTSeq.
2. Bearing in mind that the whole 95 varieties characterized were not subjected to water stress, do i need to set up another experiment entirely for the water stress and go ahead to make use of RNASeq to get the genes?
3. It is obvious that some genes will be upregulated and some will be downregulated, how do i identify these genes and how do i know if they are expressed at the onset of stress, during, or after stress?
4. when is the appropriate time to take my samples, i was considering taking at 50% flowering stage. Is this good?
Any help and insightful articles will be greatly appreciated.
Thank you.
