dc.description.abstract | Ozone is a destructive pollutant, damaging crops, and decreasing crop yield. Therefore,
there is great interest in finding strategies to alleviate ozone-induced crop losses. In
plants, ozone enters leaves through the stomata and is immediately degraded into
reactive oxygen species (ROS), producing ROS stress in plants. ROS stress can
be controlled by ROS-scavenging systems that include enzymatic or non-enzymatic
mechanisms. Our research group has developed a product from rice bran, a byproduct of rice milling which has bioactive molecules that act as an antioxidant
compound. This product is a water-soluble rice bran enzymatic extract (RBEE) which
preserves all the properties and improves the solubility of proteins and the antioxidant
components of rice bran. In previous works, the beneficial properties of RBEE have been
demonstrated in animals. However, to date, RBEE has not been used as a protective
agent against oxidative damage in agricultural fields. The main goal of this study was
to investigate the ability of RBEE to be used as a biostimulant by preventing oxidative
damage in plants, after ozone exposure. To perform this investigation, pepper plants
(Capsicum annuum) exposed to ozone were treated with RBEE. RBEE protected the
ozone-induced damage, as revealed by net photosynthetic rate and the content of
photosynthetic pigments. RBEE also decreased the induction of antioxidant enzyme
activities in leaves (catalase, superoxide dismutase, and ascorbate peroxidase) due to
ozone exposure. ROS generation is a common consequence of diverse cellular traumas
that also activate the mitogen-activated protein kinase (MAPK) cascade. Thus, it is
known that the ozone damages are triggered by the MAPK cascade. To examine the
involvement of the MAPK cascade in the ozone damage CaMPK6-1, CaMPK6-2, and
CaMKK5 genes were analyzed by qRT-PCR. The results showed the involvement of the
MAPK pathway in both, not only in ozone damage but especially in its protection by
RBEE. Taken together, these results support that RBEE protects plants against ozone
exposure and its use as a new biostimulant could be proposed. | es |
