Can anybody advise me with the best primers to be used for phylogeny of family boraginaceae especially genus Heliotropium. What about universal primers, will those give valuable information?
hi Asmaa
I think ITS - sequencing is the best. Please download and see this paper: http://www.amjbot.org/content/89/2/287.full.pdf+html
good luck
Hi Asma'a,
We have used both the nrITS and the trnK intron in Myosotis. Both provide suitable levels of resolution for our purposes. See this paper for details: https://www.researchgate.net/publication/11237191_The_origins_and_evolution_of_the_genus_Myosotis_L._(Boraginaceae)?ev=prf_pub
At the level you seem to want to work at the nrITS is likely to be useful but if you also want a chloroplast marker you may need to experiment with primers for several in order to find one or two that are suitable for your situation. This paper includes a number of possibilities:

All the best

Hi Asmaa,
We worked on Cynoglosseae using ITS and also trnL-F. Those gave reasonable resolution at tribal level. I would suggest to you to perform a variability test prior starting with massive amplifications. We found some problems amplifying herbarium material, that we solved using internal primers.
