Metabolomic profiles exhibit the influence of endoplasmic reticulum stress on sorghum seedling growth over time.

Environmental stresses disturb the endoplasmic reticulum (ER) protein folding. However, primary metabolic responses induced by ER stress remain unclear. Thus, we investigated the morphophysiological and metabolomic changes under ER stress, induced by dithiothreitol (DTT) and tunicamycin (TM) treatments in sorghum seedlings from 24 to 96 h.

Combined NaCl and DTT diminish harmful ER-stress effects in the sorghum seedlings CSF 20 variety.

Plants have developed mechanisms to avoid harmful effects of Na accumulation, such as the signaling pathway of carrier proteins Na/H (NHX) and salt overly sensitive (SOS). Besides, endoplasmic reticulum (ER) could integrate plant cell response. Thus, we aimed to understand the effects of ER homeostasis impairment, and its relationship to salt stress during early stages of the Sorghum bicolor CSF 20 a salt-tolerant variety.
