Transcriptomic and metabolomic landscape of quinoa during seed germination.

ABSTRACT:

Background

Quinoa (Chenopodium quinoa), a dicotyledonous species native to Andean region, is an emerging crop worldwide nowadays due to its high nutritional value and resistance to extreme abiotic stresses. Although it is well known that seed germination is an important and multiple physiological process, the network regulation of quinoa seed germination is largely unknown.

Results

Here, we performed transcriptomic study in five stages during transition from quinoa dry seed to seedling. Together with the GC-MS based metabolome analysis, we found that seed metabolism is reprogrammed with significant alteration of multiple phytohormones (especially abscisic acid) and other nutrients during the elongation of radicels. Cell-wall remodeling is another main active process happenin
