The Involvement of Antioxidant Enzyme System, Nitrogen Metabolism and Osmoregulatory Substances in Alleviating Salt Stress in Inbred Maize Lines and Hormone Regulation Mechanisms.

Salt stress inhibited the growth of maize. B46 and NC236 were chosen as materials and NaCl concentrations (0, 55, 110, 165, and 220 mmol L) were set. We found the activities of SOD, POD, CAT, APX, GR, MDHAR, and DHAR decreased under NaCl stress.

Comparative transcriptome analysis of salt-sensitive and salt-tolerant maize reveals potential mechanisms to enhance salt resistance.

Background: Salt stress is a devastating environmental stress that causes plant growth inhibition and yield reduction.

Objective: The identification of salt-tolerant genes brings hope for the generation of salinity-tolerant crop plants through molecular breeding.

Methods: In this study, one salt-sensitive and one salt-tolerant maize inbred line were screened from 242 maize inbred lines.

Genome-wide association study Identified multiple Genetic Loci on Chilling Resistance During Germination in Maize.

Maize (Zea mays, L.) cultivation has expanded greatly from tropical to temperate zones; however, its sensitivity to chilling often results in decreased germination rates, weak seedlings with reduced survival rates, and eventually lower yields. We conducted germination tests on the maize-282-diverse-panel (282 inbred lines) under normal (25 °C) and chilling (8 °C) conditions.
