Germplasm Resources Information Network. The variation in squirt response tends to be less variable within than among individual plants, suggesting a genetic component to the squirt response Becerra, unpublished burseda.
We also analyzed leaves of the non-squirting Bursera biflora and larvae and feces of its herbivore Blepharida flavocostatan Table 3.
Also, simple compounds often require fewer steps, which decreases their substrate and cofactor costs. The chemistry of Bursera schhlechtendalii dominated by terpenoids, mostly monoterpenes and sesquiterpenes Evans et al.
Squirting species tend to have highly volatile and simple mixtures composed mostly of one or two simple monoterpenes, while non-squirting species have heavier and more complex mixtures. They are native often for many species endemic to the Americasfrom the southern United States south through to northern Argentinain tropical and buesera temperate forest habitats.
Cluster 2 contains many of the species that typically do not release any fluids, and clusters 3 and 4 consists mostly of species that release smaller amounts than the species in cluster 1. Brusera number of species from tropical Asia were once included in this genus, but are now treated in the genus Protium.
The occurrence of complex mixtures of compounds, is a widespread phenomenon among plants that produce terpenoids and it has been associated with several factors Gershenzon and Croteau, This Sapindales schlechtehdalii article is a stub. Furthermore, larvae whose natural shields were removed and then reared on a diet of lettuce were defenseless. Wikispecies has information related to Bursera.

There is variation in resin response among individual leaves and among plants of squirting Bursera. Another explanation for the peculiar chemical simplicity of squirting burseras is a relaxation of the need for chemical defenses. If the release of a highly pressurized liquid is an effective antiherbivore defense, the chemical nature of the individual components may not be as important as in non-releasing Bursera species. Larvae of Blepharida species that feed on the Bursera species which release little or no fluids after damage, do not sever the leaf veins.
Larvae of Blepharida rhois with intact shields were avoided by the generalist predatory ant Formica subsericawhile larvae without shield were readily captured Vencl and Morton, Traditionally, plant defenses have been divided into two main categories: Extracts were analyzed by gas chromatography.
Evolutionary chemical trends in the genus are not well known, although recent studies suggest that there is considerable convergence in the production of different volatile compounds by Bursera species Becerra, The compounds of the non-releasing species are heavier and the mixture is more complex, as with B.
Trenching and vein-cutting behaviors have been reported for lepidopterans, orthopterans and coleopterans, and there is a correlation between resin canal organization and method of deactivation by insects Dussourd and Denno, Bursera schlechtendalii and Bursera biflora are representative of the squirting and non-squirting syndromes respectively.
Bursera glabrifolia Kunth Engl.

Chemical analyses of the squirting Bursera schlechtendalii black bars and the non-resin releasing Bursera biflora white bars. Related articles in Google Scholar.
Bursera penicillata fruits and leaves. They feed by mining the leaves, but they sometimes rupture the canals and die because they become covered by resins. Measurements were averaged and rounded. In other plant-herbivore systems, the physical properties of the resins are determined by their terpenoid composition.
The genus exhibits great chemical variation in the terpenoid composition the number, identity, and relative amounts of individual terpenoids; Dominguez et al. Leaves of 38 species were collected in the field and their chemical constituents extracted in ethyl acetate. This page was last edited on 10 Octoberat Also, the relative amounts of the different compounds of the mixture tend to be more even, which is reflected in lower dominance values.
Dendrogram of Bursera species based on chemical similarity. Thus, the required liquid state of resins may determine the high monoterpene fraction in squirting species of Bursera. These beetles often carry spores of pathogenic fungi that infect the tree, weaken it, and accelerate its death. Percentage of monoterpene compounds found in five squirting Bursera species black bars and four non-squirting ones white bars. Low scores on the first principal component signify an absence of compounds with low retention times.
Early-instar larvae are apparently unable to sever the leaf veins. The resin canals of Pinaceae and Bursera species contain terpenes Raffa, ; Evans et al. The volatile compounds found in the leaves of Artemisia annua differ depending on whether biotypes have glandular trichomes or not Tellez et al. When a piece of a leaf is removed, a fine syringe-like spray of resins is released. Also, water-stressed plants tend to release significantly lower amounts of resin, indicating that environmental factors can affect this response Becerra, a.
