“…There is evidence that insect play an important role in pollination of jatropha [12]. In addition, the opening time shift between male and female flowers has been reported and all these observations lead to hypothesize that jatropha should have a high level of heterozygosis as observed in other outcrossing crops [9].…”

Jatropha curcas L. (jatropha) is an undomesticated plant that has recently received great attention for its utilization in biofuel production, rehabilitation of wasteland, and rural development. Knowledge of genetic diversity and marker-trait associations is urgently needed for the design of breeding strategies. The main goal of this study was to assess the genetic structure and diversity in jatropha germplasm with co-dominant markers (Simple Sequence Repeats (SSR) and Single Nucleotide Polymorphism (SNP) in a diverse, worldwide, germplasm panel of 70 accessions. We found a high level of homozygosis in the germplasm that does not correspond to the purely outcrossing mating system assumed to be present in jatropha. We hypothesize that the prevalent mating system of jatropha comprise a high level of self-fertilization and that the outcrossing rate is low. Genetic diversity in accessions from Central America and Mexico was higher than in accession from Africa, Asia, and South America. We identified makers associated with the presence of phorbol esters. We think that the utilization of molecular markers in breeding of jatropha will significantly accelerate the development of improved cultivars.

“…J. curcas is a nonwind pollinated plant frequented by different types of visitors under natural conditions. The Eastern honey bees, Apis cerana (F.), is a generalist pollinator, also the most common and most important pollinator for J. curcas (Raju and Ezradanam 2002, Rianti et al 2010, Luo et al 2011. To obtain a high pollination efÞciency of J. curcas, we must Þrst understand how A. cerana processes the olfactory information from the ßowers of J. curcas.…”

The Eastern honey bee, [Apis cerana (F.)], is an important and common pollinator for an important biodiesel tree, [Jatropha curcas (L.)]. To understand sensitivity of A. cerana to different floral compounds, we quantified volatile floral compounds of J. curcas, then determined electroantennogram (EAG) responses of A. cerana to 11 compounds each at five doses (0.4, 4, 40, 400, and 4,000 microg) of six most active floral compounds. Our results demonstrated that floral compounds of J. curcas differ in variety and quantity while linalool is always a major constituent in floral blends from three different plantations. Antennae of A. cerana responded to all 11 floral compounds, implying a broad sensitivity of A. cerana to different floral compounds of J. curcas. Antennae of A. cerana were most sensitive to six compounds, including all aldehydes (decanal, hexanal, nonanal, and octanal), linalool, and an alcohol (3-hexenol), suggesting that A. cerana possesses chemoreceptors to aldehydes, linalool, and alcohol on the antenna. Furthermore, low doses elicited a zero EAG response and high doses a positive one under all of six most active compounds. Thus, EAG responses of A. cerana were both chemical specific and dose-dependent. Our results here suggest that A. cerana is senstive to various floral compounds, and linalool in the floral blends of J. curcas plays a key role to attract A. cerana.

“…Because of the rather open nature of the ßowers, wide arrays of visitors are attracted to its easily accessible nectar, and bees often are regarded as most effective pollinators (Raju and Ezradanam 2002, Bhattacharya et al 2005, Rianti et al 2010, Luo et al 2011. Ants were the most abundant visitors to the ßowers of J. curcas (Banjo et al 2006, Rianti et al 2010, and make most visits to both male and female ßowers (Raju and Ezradanam 2002).…”

“…However, ants have been considered ineffective pollinators to J. curcas for several reasons. Ants stay for long durations in the ßowers (Rianti et al 2010), and their mobility is low (Luo et al 2011). They are small in size and possess a smooth integument (Faegri andVan der Pijl 1979, Proctor et al 1996), and thus are thought to be inefÞcient pollen carriers.…”

Ants are the most abundant visitors to the flowers of Jatropha curcas L., but it is not clear how much they contribute to the pollination of this plant. In this study, we observed floral visitor assemblage and foraging behavior of ants, measured pollen loads carried by ants and deposited on stigmas, and determined the contribution of ants to the female reproductive success of J. curcas through exclusion experiments. Ants were the most abundant pollinators, accounting for 71.03 and 78.17% of total visits at two study sites. Among different ant species, Tapinoma melanocephalum (F.) is always the most abundant and the only common ant species at two study sites, which might suggest its important role in the pollination of J. curcas. Pollen loads carried by ants were significantly different among different species at two study sites. Pollen loads carried by ants increased with increased body length. Although the flowers exposed only to the ants produced less fruit than those exposed only to the winged visitors, ants alone resulted in almost 60% fruit set. Thus, ants could play a major role in the pollination of J. curcas if winged insects are absent.
