Kaolin particle film application lowers oxidative damage and DNA methylation on...
Bernardo, S.; Dinis, L. -T.; Luzio, A.; Pinto, Glória; Meijón, Mónica; Valledor, Luís; Conde, A.; Gerós, H.; Correia, C. M.; Moutinho-Pereira, J.The exogenous kaolin application in grapevine has shown a great potential as summer stress mitigation strategy because it positively impacts fruit quality as a result of many molecular and biochemical changes. In the present study we wanted to address the hypothesis that the observed improved antioxidant capacity could also result from a more efficient enzymatic antioxidant system response. For that purpose, th...
Rice (Oryza sativa L.) phenolic compounds under elevated carbon dioxide (CO2) c...
Goufo, P.; Pereira, J.; Moutinho-Pereira, J.; Correia, C.; Figueiredo, N.; Carranca, C.; Rosa, E.; Trindade, HPrevious studies have shown that elevated levels of carbon dioxide [CO2] may increase, decrease, or have no effect on the concentrations of phenolic compounds in plants. The underlying causes of these variations in responses remain poorly understood. In the present study, it was hypothesized that different plant responses come mainly from the duration of exposure to the gas, growing conditions, and sampling pro...
Study of the effects of foliar application of ABA during acclimatization
Dias, M. C.; Correia, C.; Moutinho-Pereira, J.; Oliveira, H.; Santos, C.This study aims to elucidate the effects of abscisic acid (ABA) foliar application on plant hardening during ex vitro acclimatization using a forest model species Ulmus minor L. Plant leaves were sprayed with ABA (0, 50 and 100 μM) immediately after ex vitro transfer and twice a week for the first 3 weeks of acclimatization. After this period, parameters related with photosynthesis, hormone levels and oxidative...
Photosynthetic parameters of Ulmus minor plantlets affected by irradiance durin...
Dias, M. C.; Pinto, G.; Correia, C. M.; Moutinho-Pereira, J.; Silva, S.; Santos, C.In order to set up large-scale acclimatization protocols of micropropagated plants, an in-depth knowledge of their physiological responses during in vitro to ex vitro transfer is required. This work describes the photosynthetic performance of Ulmus minor micropropagated plants during acclimatization at high irradiance (HI; 200 ± 20 μmol m-2 s-1 or low irradiance (LI; 100 ± 20 μmol m-2 s-1). During this experime...
