Comparative transcriptome analysis provides key insights into seedling development in switchgrass (Panicum virgatum L.).

ABSTRACT:

Background

Switchgrass (Panicum virgatum L.), a warm-season perennial C4 plant, can be used as a forage plant, a soil and water conservation plant, a windbreak plant, and as a good source of biofuels and alternative energy with low planting costs. However, switchgrass exhibits low rates of seedling development compared to other crops, which means it is typically out-competed by weeds. There is a large variation in seedling development rates among different plantlets in switchgrass, which limits its usefulness for large-scale cultivation. Little is currently known about the molecular reasons for slow seedling growth.

Results

Characterization of the seedling development process via growth indices indicated a relatively stagnant growth stage in switchgrass. A total of 67
