Secretory organelle and mitochondrial alterations induced by fusaric acid in root cells of Zea mays

Effect of fungal fusaric acid on the root and leaf physiology of watermelon (Citrullus lanatus) seedlings

“…Investigations on fusarium wilt of watermelon have been focused on process of fungal hyphae penetrating into vascular vessel of host, variations of some antioxidant enzymes and stimulation of cell apoptosis and death (Manoranjan and Dinabandhu 1976;Garcia-Limones et al 2002;Fink et al 1988;Schraudner et al 1992;Hartman et al 2004;Leidi and Shahsavan 2006) and alteration of cell growth, mitochondrial activity and membrane permeability, reduction of stomatal conductance and chlorophyll content (Gaumann 1958;Pavlovkin 1988;Bouizgarne et al 2006;Andrew et al 2002;Boyer 1976), increase of electrolyte leakage (Linskens 1955;Arias 1985;Marre and Vergani 1993), causing modification of membrane potential (Kohler and Bentrup 1983;Dalton and Etherton 1984;Marre and Vergani 1993;Pavlovkin 1988), inhibition of respiratory activity (Kuo and Scheffer 1964;Arias 1985;Marre and Vergani 1993), decreasing ATP levels (Kohler and Bentrup 1983;Dalton and Etherton 1984), cutinaseadded penetration of F. spp. (Shaykh et al 1977) and transduction of necro-peptide from F. oxysporum (Bae et al 2006) in several plant species hosts.…”

Effect of fusaric acid on biomass and photosynthesis of watermelon seedlings leaves

“…Some studies have been reported on the toxic effect of FA on some endogenous enzymes of plants, alteration of cell growth, mitochondrial activity and membrane permeability (GAUMANN 1958;PAVLOVKIN 1998;BOUIGARNE et al 2006), increase of electrolyte leakage (LINSKENS 1955;ARIAS 1985;MARRE et al 1993), causing modification of membrane potential (KOHLER and BENTRUP 1983;DALTON and ETHERTON 1984;MARRE et al 1993;PAVLOVKIN 1998), inhibition of respiratory activity (KUO and SCHEFFER 1964;ARIAS 1985;MARRE et al1993) and decreasing ATP levels (KOHLER and BENTRUP 1983;DALTON and ETHERTON 1984) in several plant species. However little is available to direct and integrated impact of FA on growth and photosynthesis of watermelon plant.…”

“…spp, which cause infections in cereal grains and other agricultural commodities (WANG and NG 1999). Fusaric acid, 5-butylpicolinic acid or 5-butyl-2-pyndine carboxylic acid, is a fusarium mycotoxin whose only known effect is the increase of mitochondrion and plasma membrane permeability (ARIAS 1985;TELLES-PUPULIN et al 1996;TELLES-PUPULIN et al 1998).…”

Some aspects of the phytotoxic action of fusaric acid on primary Ricinus roots

“…It alters the permeability of plant membranes (Gäumann 1958, Pavlovkin 1998, increases electrolyte leakage (Linskens 1955, Arias 1985, Marrè et al 1993, causes modification of membrane potential (Köhler and Bentrup 1983, D'Alton and Etherton 1984, Marrè et al 1993, Pavlovkin 1998, inhibits respiratory activity (Kuo and Scheffer 1964, Arias 1985, Marrè et al 1993) and decreases ATP levels (Köhler andBentrup 1983, D'Alton andEtherton 1984) in several plant species. However, fusaric acid was one of the first fungal metabolites implicated in the pathogenesis.…”
