dc.description.abstract | Abstract
Dehydrins (DHNs) are stress proteins involved in the development of protective reactions in plants against dehydration. The
relationship between DHNs and morphological responses such as leaf rolling in plants exposed to water defcit is not well
known. In this study, we detected how variations in DHN levels afect the leaf rolling response in maize exposed to osmotic
stress in relation to the antioxidant system and ABA level. In this context, we altered the DHN levels in maize seedlings
by treatment with bio-regulators (salicylic acid and abscisic acid) under PEG6000-free and PEG6000-induced osmotic stress.
When the DHN levels were increased by the bio-regulators (25 µM SA and 100 µM ABA), the relative expression level of
the Zea mays dehydrin COR410 gene increased in the seedlings, while reactive oxygen species (ROS) and leaf rolling grade
decreased. Moreover, induction of DHNs caused increases in the antioxidant enzyme activity and content of antioxidant
substances, and very high amounts of endogenous abscisic acid. When DHN level was suppressed by a bio-regulator (200 µM
SA) in the maize seedlings, dehydrin COR410 expression level decreased, while ROS and the leaf rolling grade increased.
Moreover, the antioxidant enzyme activity and content of antioxidant substances decreased in the seedlings, while the
amount of abscisic acid increased. Taken all together, an increase in DHN level by bio-regulator treatment can stimulate the
antioxidant system, enable abscisic acid regulation, and thus reduce leaf rolling through decreased ROS levels. The results
also indicated that DHNs may be involved in the signal pathways inducing expression of some genes related to leaf rolling
response, possibly by modulating ROS levels, in maize seedlings exposed to osmotic stress. | en_US |
