“…MacFarlane et al (2003) reported that significant relationships between A. marina leaf tissue and sediment did occur, but were weak and were not maintained temporally. The recorded leaf Pb levels in this study could present a future concern as non-essential metals often become toxic at low concentrations (MacFarlane and Burchett, 2001). Further studies of the mangroves in Punta Mala Bay and nearby sites would have to be conducted to investigate whether or not similar processes occurred in L. racemosa.…”

“…The symptoms of a negative cadmium effect reflect not only the biochemical and microbiological soil properties, but also the quality and plant yielding (Čechmánková et al 2011). Cadmium is an inhibitor of δ-aminolevulinic acid synthetase and protochlorophyllide reductase as well as the enzymes of chlorophyll biosynthesis pathway (MacFarlane & Burchett 2001). The response of plants to its toxicity is an induction of salicylic acid, jasmonic acid, nitrogen oxide, and ethylene oxide and an increase in ACC activity (1-aminocyclopropane-1-carboxylic acid) (Maksymiec et al 2007).…”

“…Otro parámetro empleado para valorar la capacidad de adaptación de E. gracilis al Cu 2+ fue la producción de pigmentos fotosintéticos, los cuales están relacionados con la viabilidad celular ya que se asocian con la capacidad fotosintética del organismos. 10 En este sentido, los resultados mostraron que la producción de clorofila a, b y carotenoides totales presentaron un comportamiento dosis dependiente ya que se observó una disminución significativa a mayores dosis del metal (Figura 3). Esta reducción en las concentraciones de pigmentos fotosintéticos pueden ser el resultado del efecto directo de los iones de Cu 2+ que pueden inhibir la síntesis de la clorofila y carotenoides.…”
