“…POX was found to be one of the components of the defence systems that are stimulated in plants in response to infection by pathogens such as Fusarium oxysporum (Morkunas and Gmerek, 2007). It was reported that Fusarium infection resulted in the increased activity of antioxidant enzymes together with increased levels of ROS and lipid peroxidation in cucumber roots (Ye et al, 2006;El-Khallal, 2007;Mandal et al, 2008). Mechanisms involved in plant perception and altered carbohydrate balance in response to pathogenesis have been highlighted in the literature (Roitsch, 1999;Sheen et al, 1999).…”

“…The development of an antioxidant defence system in plants protects them against oxidative stress damage, by either the partial suppression of ROS production, or the scavenging of the ROS already produced (Torres et al, 2006;Ye et al, 2006;Cavalcanti et al, 2007). Thus, various antioxidant enzymes such as peroxidase (POX), superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) participate in the ROS metabolism during pathogen attacks.…”

Inoculating wheat (cv. Giza 164) with various Fusarium species had different effects on the catalase (CAT), peroxidase (POX) and ascorbate peroxidase (APX) activity in different plant tissues. The CAT activity induced in the shoots of wheat plants by some pathogens (F. merismoides, F. moniliforme, F. poae and F. sambucinum) was relatively higher than that induced by other pathogens. The results showed an increase in POX activity in infected shoots except those inoculated with F. sambucinum, where the POX activity decreased. Inoculating wheat plants with individual Fusarium species or with a mixture of pathogens caused an increase in APX in the shoots, except for those treated with F. poae, where the APX activity decreased. The activity of these antioxidant enzymes thus increased in most cases in the shoot system of wheat plants under Fusarium infection. Investigations on the metabolic activity of wheat plants inouculated with individual Fusarium species or with a mixture of pathogens showed higher contents of all the protein fractions, soluble sugars, total free amino acids and proline. The K + and Ca 2+concentrations decreased to various extents in different cases. The Na + content increased in wheat shoots, especially after inoculation with F. merismoides. The results signify that the most serious infection was caused by F. culmorum, F. graminearum and F. oxysporum and by a mixture of all the Fusarium species.

“…Reduced proliferation pattern and faster root shedding can be interpreted as avoidance response to unfavourable conditions which temporarily reduced soil exploration and resource uptake by roots. In addition, soil sickness enhances the risk of infection by soil borne pathogens through an indirect biochemical and physiological effect (Ye et al 2006). However, the associations among the accumulation of toxins, root functional activity and risk of infection remains a complex issue to be further examined.…”

Growth of ‘M9’ apple root in five Central Europe replanted soils

Soil sickness is a widespread problem in replanted apple orchards with a complex symptomatology and etiology influenced by soil and climate conditions. Consequently, a conclusive technical solution is still lacking for intensive apple orchards. The present work aims to analyze the morphological and functional changes occurring in the M9 apple root systems growing in pot filled with soil derived from five different European growing areas. For each growing area, the soil was collected from the apple orchard and used directly in the pot or gamma-ray sterilized before potting. Soil from a neighborhood fallow was also used as control for each growing area. In the non-sterilized replant soils plants developed poor root systems due to a limited biomass allocation. Fibrous roots production was particularly compromised. The roots had a smaller diameter and a lower ramification index. The root cell membrane integrity was also lower. Gamma-ray sterilized replant soils increased root growth, branching and cell integrity, while nearby fallow soil induced an intermediate root behavior. The magnitude of the symptoms showed a significant interaction between soil treatment and sampling site and root growth was correlated with the organic matter content in the soils.

“…In cultivation, alfalfa (Medicago sativa L.) and cucumber are known as species displaying the strongest autotoxic potential. Phytotoxicity of cinnamic acid, the most important after benzoic acid allelochemical, in root exudates and root extracts of cucumber, is associated with alteration in ROS metabolism (Yu et al 2003;Ye et al 2006;Ding et al 2007;Li et al 2011a). Cinnamic acid is considered to act as an autotoxic agent leading to soil sickness, which is a serious problem in horticultural crop production.…”
