Impact of varying diurnal temperature ranges on regulation of multiple physiological traits of a drought-tolerant moss (Grimmia pilifera).

ABSTRACT: Mosses that usually exist as gametophytes lack true roots, stems, and leaves, and their physiological activity is highly sensitive to environmental changes. The increase of diurnal temperature range (DTR) is one of the important characteristics of global climate change, but it is still unclear how mosses respond to the change of DTR. The typical drought-tolerant and saxicolous moss Grimmia pilifera was used as the research subject, two DTR treatments were set up: 20/10 ℃ (day/night; as natural habitat temperature) and 30/10 ℃ (day/night; as increased DTR). After homogenized cultivation, three dehydration-rehydration cycles and physiological measurements were conducted on days 7, 14, and 21 to investigate the comprehensive response of mosses to change in DTR over time. The results showed th
