Development of species diagnostic SNP markers for quality control genotyping in four rice (Oryza L.) species by Ndjiondjop, M.N., Semagn, K., Zhang, J., Gouda, A.C., Kpeki, S.B., Goungoulou, Alphonse J., Wambugu, P., Dramé, K.N., Bimpong, I.K., Zhao, D.

“…The objectives of the present study were to (i) determine the extent of genotyping error (reproducibility) on DArTseq-based single-nucleotide polymorphisms (SNPs); (ii) determine the proportion of misclassified accessions across 3134 samples representing three African rice species complex (Oryza glaberrima, O. barthii, and O. longistaminata) and an Asian rice (O. sativa), which are conserved at the AfricaRice gene bank; and (iii) develop species- and sub-species (ecotype)-specific diagnostic SNP markers for rapid and low-cost quality control (QC) analysis. Genotyping error estimated from 15 accessions, each replicated from 2 to 16 times, varied from 0.2 to 3.1%, with an overall average of 0.8%. …”

KAZNET: An open-source, micro-tasking platform for remote locations by Chelanga, Philemon, Fava, Francesco P., Alulu, Vincent, Banerjee, Rupsha R., Naibei, Oscar, Taye, Masresha, Berg, M., Galgallo, Diba, Gobu, Wako, Lepariyo, Watson, Muendo, K., Jensen, Nathaniel D.

“…KAZNET has shown to be effective for collecting high frequency and repeated measures from markets, households and rangelands in remote regions at relatively low cost compared to traditional survey methods. While the successes of micro-tasking are promising, there are clear trade-offs and complementarities between micro-tasking and standard surveys methods, which researchers and practitioners need to consider when implementing either approach.…”
