Dear friends,

The Central Tuber Crops Research Institute (CTCRI), Kerala, India is the premier research organisation in India under Indian Council of Agricultural Research (ICAR), Govt. of India conducting research exclusively on tropical tuber crops such as Cassava, Sweet Potato, Amorphophallus, Yams, Colocasia etc.

Of metabolites and metabolomics in cassava!

Recently I was in a meeting and had some deep discussion on the use of metabolites and metabolomics in cassava improvement. Even though I have limited experiences in this area, it sounded interesting to me and I was wondering if there are members of the community who have something to share (even if from other crops) and how it might be of benefit to the cassava breeding community of practice. Anyone, or ideas?

For some traits, phenotyping specific metabolites, or a large suite of metabolites (metabolomics) might be quite productive. For example, in maize, phenotyping the levels of metabolites in the carotenoid pathway was valuable in identifying markers for improving B-carotene levels and phenotyping metabolites in the tocopherol pathway in identifying markers for improving vitamin E content. Phenotyping abscisic acid (ABA) metabolites has also been successful in identifying genes with SNPs that associate with ABA accumulation (Setter et al. 2011. J Exp Bot 62:701). Metabolic pathways such as these might be particularly amenable for such an approach, given their relatively low complexity. Complex traits (drought tolerance, yield) are more challenging. Please refer to a recent open-access review: Setter. 2012. Frontiers in Physiology. 3:1-11

Thanks Tim. Quite interesting. I will check on these articles and get back on options for future approaches.
