Differential chemical allocation and plant adaptation: A Py-MS Study of 24 species differing in relative growth rate

et al. 1995

The chemical composition of leaves of 24 wild species differing in potential relative growth rate (RGR) was analysed by pyrolysis-mass spectrometry. The variation in RGR significantly correlated with differences in chemical composition: slow-growing species were richer in glucan-based polysaccharides and in C 16:0 fatty acid, whereas fast growing ones contained more protein (other than those incorporated in cell walls) and chlorophyll, sterols and diglycerides. Other, apparently significant correlations, e.g. for pentose-based hemicellulose and for guaiacyl lignin appeared solely based on a group separation between mono-and dicotyledonous species.Considering the eleven monocotyledonous and thirteen dicotyledonous species separately, correlations were found in addition to the previously mentioned general ones. Within the group of the monocotyledons the low-RGR species were significantly enriched in pentose-based hemicellulose, ferulic acid and (hydroxy)proline-rich cell wall protein and nearly significant in guaiacyl and syringyl lignin, fast-growing species contained more potassium. Within the group of the dicotyledons slow-growing species were enriched in triterpenes and aliphatic wax esters.In general, the monocotyledons contained more cell wall material such as pentose-based hemicellulose, ferulic acid, glucans (including cellulose) and guaiacyl-lignin, and also more aliphatic wax esters, than the dicotyledons. The dicotyledons, on the other hand, contained somewhat more protein than the grasses.Per unit weight of cell wall, the amount of (hydroxy)proline-rich protein in low-RGR species was comparatively low. A higher investment of cell wall proteins to explain the low rate of photosynthesis per unit of leaf nitrogen of slow-growing species as suggested by Lambers and Poorter (1992), therefore, seems unlikely.Abbreviations: HPRP-(hydroxy)proline-rich protein(s), L A R -leaf area ratio, L W R -leaf weight ratio, MVAmultivariate analysis, NAR-net assimilation rate, P C -principal component, PNUE-photosynthetic nitrogen use efficiency, PyGCMS-pyrolysis -gas chromatography-mass spectrometry, PyMS-pyrolysis mass spectrometry, R G R -relative growth rate, SLA-specific leaf area, SLM -specific leaf mass

“…Rishitin and/or solavetivone are phytoalexins that were reported to inhibit the growth of different microorganisms, including P. infestans [37,38]. Rishitin was also shown to inhibit Botrytis cinerea mycelial growth in both solid and liquid media [39]. The results presented in this article showed that MEM induced the accumulation of phytoalexins, particularly rishitin, lubimin and oxylubimin in potato tubers (Fig.…”

Plants recognize certain microbial compounds as elicitors in their active defence mechanisms. It has been shown that a series of defence reactions are induced in potato plant cells after treatment with water-soluble hyphal wall components prepared from Phytophthora infestans. In this study, a methanol extract from mycelia of P. infestans (MEM), which contains lipophilic compounds, was used as another elicitor for the induction of the defence reactions in potato. MEM elicitor induced reactive oxygen species (ROS), especially O2(-) and H2O2 production, and nitric oxide (NO) generation in potato leaves and suspension-cultured cells. Hypersensitive cell death was detected in potato leaves within 6-8 h after MEM elicitor treatment. The accumulation of phytoalexins was detected by MEM elicitor treatment in potato tubers. In potato suspension-cultured cells, several defence-related genes were induced by MEM elicitors, namely Strboh, Sthsr203J, StPVS3, StPR1, and StNR5, which regulate various defence-related functions. Enhanced resistance against P. infestans was found in MEM-treated potato plants. These results suggested that MEM elicitor is recognized by host and enhances defence activities to produce substances inhibitory to pathogens.

“…Thus, α-tomatine may partially restrict B. cinerea infections of unripe tomato fruit, but it is not the only mechanism fruit use for resistance. Early studies reported that the sesquiterpene, rishitin, is produced in unripe tomato fruit as a consequence of B. cinerea infection and that it may boost the deleterious effects of α-tomatine on the fungus (Glazener and Wouters 1981 ).…”

Botrytis cinerea causes gray mold decay in the ripe fruit of many plant species leading to signifi cant economic losses for the producers, distributers and consumers of fresh and stored produce. This chapter summarizes current knowledge about the biology of a model fl eshy fruit, tomato, during B. cinerea infections. The information presented emphasizes how ripening regulation and events in the host infl uence resistance when fruit are unripe and susceptibility when fruit are ripe. Fruit ripening regulators (e.g., transcription factors, epigenetic modifi ers and hormones) and events unique to ripening that can impact the susceptibility of tomato fruit to B. cinerea are discussed. Understanding the processes in the fruit that underlie the shift from resistance to susceptibility during ripening and resolving how B. cinerea modifi es its strategies of infection in response to the developmental changes of the host may guide efforts to improve the resistance of fruit to B. cinerea and other fungal pathogens.
