An integrated physiological indicator and transcriptomic analysis reveals the response of soybean buds to high-temperature stress.

ABSTRACT:

Background

Under global warming, high temperature (HT) has become a major meteorological factor affecting soybean production. To explore the candidate genes and regulatory mechanism of the soybean bud response to HT stress, previously identified as HT-tolerant ('Handou14'; HD14) and HT-sensitive ('Jiadou36'; JD36) were treated for 5 days in an artificial climate incubator either with HT (43 °C (day)/ 33 °C (night), 16 h light/8 h darkness) or the non-stress growth condition (25 °C, 16 h light/8 h darkness) as the control at the bud stage were used as experimental materials in this study. After HT treatment, changes in physiological indicators including hypocotyl length, enzyme activity and hormone content were detected; at the same time, the cotyledons, hypocotyls, and main roots w
