Acclimation of sugar beet in morphological, physiological and BvAMT1.2 expression under low and high nitrogen supply.

ABSTRACT: Understanding the response and tolerance mechanisms of nitrogen (N) stress is essential for the taproot plant of sugar beet. Hence, in this study, low (0.5 and 3 mmol/L; N0.5 and N3), moderate (5 mmol/L; N5; control) and high (10 and 12 mmol/L; N10 and N12) N were imposed to sugar beet to comparatively investigate the growth and physiological changes, and expression pattern of the gene involving ammonia transporting at different seedling stages. The results showed that, different from N5 which could induce maximum biomass of beet seedlings, low N was more likely to inhibit the growth of beet seedlings than high N treatments. Morphological differences and adverse factors increased significantly with extension of stress time, but sugar beet seedlings displayed a variety of physical responses
