“…Higher plants have evolved defense mechanisms against such attack of natural enemies. For instance, plants accumulate wound-healing compounds such as suberin in response to wounding [1] and prepare defense chemicals including repellents and toxins as well as physical defense reaction such as cell wall reinforcement. Moreover, it has been reported that phytoalexins, antimicrobial compounds produced by plants in response to pathogen infections, are accumulated after wounding [2].…”

Citrus plants are well known as a rich source of functional chemicals however, metabolites involved in defense responses against environmental stresses are not yet well understood. "mong environmental stresses, mechanical wounding is a continuous threat toward the growth and survival of plants. Recent advances in analytical technology and informatics enable comprehensive analysis of primary and secondary metabolites. In this chapter, metabolic proiling of leaf metabolites in seven Citrus species during responses against wound stress as well as defense-related phytohormone treatments was described. Moreover, we discussed current metabolomic techniques, application of these techniques to researches on Citrus defense responses and metabolic proiling-oriented identiication of novel compounds.

“…In a symbiosis, repairing the hole hypothetically would allow the plant to conserve energy on repairing wounds, but this benefit may be unlikely because eventually the trees form natural scars around the wounds using their own defenses (Fig. 2c; see Vasyukova et al 2011). Ant repair behavior may be unlikely to benefit the plant directly, and thus the behavior may differ from microbial symbionts that facilitate wound healing in their hosts, which is beneficial to both (Poutahidis et al 2013).…”

Some Azteca ants are well-known symbionts that defend their Cecropia host plants against herbivory, although there is considerable variability in behavior among colonies, conditions, and species. In exchange, ants receive food, and also shelter within the plants’ internodes. Here we demonstrate that ants repair damage to the host plant when their brood is directly threatened. Using comminuted plant fibers and an unidentified binding liquid (probably plant sap) ants generally began patching holes in the tree trunk immediately, and significantly reduced the size of the hole 2.5 hours after it was created, and they generally completed the repairs within 24 hours.

“…Our research mainly concerned about the metabolic responses of C. roseus to mechanical wound in roots or leaves, trying to compare their resulting difference. In contrast to the previous reports regarding wound induced metabolic response, we employed high-throughput method to give more comprehensive profiling of wound-affected metabolism in this study (Vasyukova et al 2011). The GC-MS and LC-MS technologies were used to dissect the primary and secondary (TIAs and PCs) metabolites between LT and RT group plants.…”

“…For instance, local and systemic location were included in the process of wound repair to prevent the penetration of infection (Rasmann and Agrawal 2009). The biosynthesis of chemical compounds, mainly secondary metabolites whose production is triggered by interference factor, is a common defense strategy (Rasmann and Agrawal 2009;Vasyukova et al 2011). Secondary metabolites are considered to biosynthesize specially to adapt to environmental stresses (Nakabayashi and Saito 2015).…”

The mechanical wound is one of the unavoidable threats to survival of plants. More researchers focus on the effect of mechanical wound to the over-ground tissues. And the effects of wound to roots were frequently ignored, although it is an important organ for plant growth. In our studies, the metabolomics study was performed to reveal the mechanical wound effects in Catharanthus roseus on roots and leaves by combining gas chromatography-mass spectrometer (GC-MS), liquid chromatograph-mass spectrometer (LC-MS) and statistical analyses. The metabolic response of TIAs and PCs in plants to wound was most active at 0.5 h after treatment via Q value analysis. At this time point, then significantly responsive primary metabolites and specific secondary compounds (TIAs and PCs) were screened by PLS-DA score plot. In this case, the treatments of CK, LT (wound to leaves) and RT (wound to roots) were clearly distinguished. The targeted compounds include 8 sugars, 4 TIAs and 12 PCs and they displayed specific responses to CK, LT and RT treatments. Under RT group, plants invest more resources on the local responses using TIAs and the color reactions to regulate wound close using PCs. Whereas, LT group might lay emphasis on systemic responses via TIAs induced by SA (salicylic acid) and gallic acid. Our studies provide some basic data for further investigations of the defensive mechanism on roots treated by mechanical wound.
