Saturation of a run

HelloNIce to see some of you at Adelaide, and the research is awesome.  We pyrosequence fungal endophytes (fungi occurring inside plant tissues) directly from the plant material, and analyse the resulting mini-barcodes.   Is there a method to see that in your run, you have completely saturated a lane, so there may be missing data in the output, or that all of your products are there? This is difficult because we are doing this for the first time, so there is no benchmark to compare…See More

Bevan Weir replied to Marieka Gryzenhout's discussion 'Collecting macrofungi for barcoding' in the group Fungi
"Hi,   What I have done in the past is put a small amount of fresh tissue in a buffer (e.g. CTAB) in a 1.5 mL tube, then dry down the rest of the specimen for the herbarium. You will need to have collection codes to link the samples of course.…"

Collecting macrofungi for barcoding

Hi all I am about to go on an official barcoding trip in South Africa. Besides the small ascomycetes that is more my specialty, I will also collect some larger fungi.  THis trip has a public profile, so the larger fungi will be there for the people to better understand and to attract their attention.  Because I want to do it properly, are there any do's and dont's when I collect the larger fungi and preparing them for barcoding, e.g. how much tissue must I put in directly, I should probably dry…See More

Field Operations

Creating barcode reference records often begins with a collecting event in the field, but without the right techniques the specimen may never qualify as a high-quality barcode record. Come exchange information on field protocols!See More
