Genome-wide transcriptome analysis of the orphan crop tef (Eragrostis tef (Zucc.) Trotter) under long-term low calcium stress.

ABSTRACT: Calcium (Ca²⁺) is one of the essential mineral nutrients for plant growth and development. However, the effects of long-term Ca²⁺ deficiency in orphan crops such as Tef [(Eragrostis tef) (Zucc.) Trotter], which accumulate high levels of Ca in the grains, remained unknown. Tef is a staple crop for nearly 70 million people in East Africa, particularly in Ethiopia and Eritrea. It is one of the most nutrient-dense grains, and is also more resistant to marginal soils and climatic conditions than main cereals like corn, wheat, and rice. In this study, tef plants were grown in a hydroponic solution containing optimum (1 mM) or low (0.01 mM) Ca²⁺, and plant growth parameters and whole-genome transcriptome were analyzed. Ca⁺²-deficient plants exhibited le
