“…Many plant species have expressed multiple resistance traits (Agrawal & Spiller 2004;Kobayashi et al 2008;Olson et al 2009) and tolerance (Strauss & Agrawal 1999). For example, tomato (Lycopersicum esculentum Mill.)…”

“…(Leitner, Boland & Mith€ ofer 2005) and tobaccos (Nicotiana spp.) (Olson et al 2009) show a biotic resistance trait by volatiles and show direct resistance traits such as trichomes and secondary metabolites. Radish (Rapbanus sativus L.) and rough potato (Vincetoxicum hirundinaria L.) show chemical resistance and tolerance (Siemens et al 2003;Muola et al 2010).…”

“…Generally, resistance to insects is greater in plants that have been previously damaged by herbivores as compared to undamaged plants (Stout et al 2009). However, induced responses to herbivores are complex and depend on many factors, including plant species (Hui and Jin 2004), plant genotype (McGuire and Johnson 2006), attacking insect herbivore characteristics (Agrawal 2000;Mattiacci et al 2001;Zong and Wang 2007), as well as abiotic parameters, such as nitrogen and water availability (Olson et al 2009). Furthermore, induced resistance is known to vary in its timing and in within-plant allocation, two aspects that are fundamental for understanding the process of induced resistance in an ecological and evolutionary context (Baldwin and Preston 1999;Kaplan et al 2008a).…”

Induction of plant resistance by herbivory is a complex process, which follows a temporal dynamic and varies spatially at the within-plant scale. This study aimed at improving the understanding of the induction process in terms of time scale and within-plant allocation, using apple tree seedlings (Malus 9 domestica) as plant model. Feeding preferences of a leaf-chewing insect (Spodoptera littoralis) for previously damaged and undamaged plants were assessed for six different time intervals with respect to the herbivore damage treatment and for three leaf positions. In addition, main secondary defense compounds were quantified and linked to herbivore feeding preferences. Significant herbivore preference for undamaged plants (induced resistance) was first observed 3 days after herbivore damage in the most apical leaf. Responses were delayed in the other leaf positions, and induced resistance decreased within 10 days after herbivore damage simultaneously in all tested leaf positions. Chemical analysis revealed higher concentrations of the flavonoid phloridzin in damaged plants as compared to undamaged plants. This indicates that herbivore preference for undamaged apple plants may be linked to phloridzin, which is the main secondary metabolite of apple leaves. The observed time course and distribution of resistance responses within plants contribute to the understanding of induction processes and patterns, and support the optimal defense theory stating young tissue to be prioritized. Moreover, induced resistance responses occurred also basipetally in leaves below the damage site, which suggests that signaling pathways involved in resistance responses are not unidirectional.

“…However, few studies have focused on the effects of environmental conditions on the effectiveness of both direct and indirect defenses (Olson et al 2009;Yamawo and Hada 2010). The present study is the first to show variations in the development of multiple defense traits in relation to the soil moisture condition in plants with a facultative ant-plant mutualism.…”

“…Soil moisture is one environmental factor that influences the development of plant defense traits. For example, it has been reported that chemical and physical defenses develop at a low level of soil moisture (Levin 1973;Wilkens et al 1996;Pérez-Estrada et al 2000;Gonzáles et al 2008;Olson et al 2009), and that the amount of induced volatile emissions from the injured plant tissue increases under low water availability (Takabayashi et al 1994;Garcia et al 1987;Frischknecht et al 1987). However, the influence of soil moisture on the biotic defense by ants has scarcely been elucidated.…”

Variations in direct and indirect defenses against herbivores on young plants of Mallotus japonicus in relation to soil moisture conditions

Some plant species develop multiple defense traits. To test the hypothesis that plants with both direct and indirect defense traits mainly develop the direct and indirect defense traits under the low and high soil moisture conditions, respectively, the development of multiple defense traits on the young plants of Mallotus japonicus (Thunb.) Muell. Arg., and the number of ants on the plants were experimentally examined under different soil moisture conditions. Under the low soil moisture condition, the plant growth declined, and the trichomes and pellucid dots developed well. The pearl bodies developed on the plants under the high soil moisture condition. The volume of extrafloral nectar secreted and the number of ants on the plants significantly increased under the high soil moisture condition. These results clearly show that the young plants of M. japonicus firmly develop sound direct defense traits under the low soil moisture condition, and they develop indirect defense traits that are less reliable but have relatively low costs under the high soil moisture condition.
