“…These organisms are an important source of genes involved in stress tolerance and models for elucidating the steps that result in the limitation of photosynthesis efficiency. This feature is more relevant when these native plants have great agronomical potential like Jatropha curcas L. (physic nuts), a biofuel source of high quality (Achten et al, 2010).Ricinus communis L. (castor beans) is widely cultivated worldwide as a source of special non-edible oil (Barbour and Buckley, 2007). These species are C3 plants and display contrasting tolerances in response to abiotic stress (Aragão et al, 2012;Babita et al, 2010;Dai et al, 1992;Silva et al, 2012).…”

Higher plants display different adaptive strategies in photosynthesis to cope with abiotic stress. In this study, photosynthetic mechanisms and water relationships displayed by Jatropha curcas L. (physic nuts) and Ricinus communis L. (castor bean), in response to variations in environmental conditions, were assessed. R. communis showed higher CO 2 assimilation, stomatal and mesophyll conductance than J. curcas as light intensity and intercellular CO 2 pressure increased. On the other hand, R. communis was less effective in stomatal control in response to adverse environmental factors such as high temperature, water deficit and vapor pressure deficit, indicating lower water use efficiency. Conversely, J. curcas exhibited higher photosynthetic efficiency (gas exchange and photochemistry) and water use efficiency under these adverse environmental conditions. R. communis displayed higher potential photosynthesis, but exhibited a lower in vivo Rubisco carboxylation rate (Vcmax) and maximum electron transport rate (Jmax). During the course of a typical day, in a semiarid environment, with high irradiation, high temperature and high vapor pressure deficit, but exposed to well-watered conditions, the two studied species presented similar photosynthesis. Losing potential photosynthesis, but maintaining favorable water status and increasing non-photochemical quenching to avoid photoinhibition, are important acclimation mechanisms developed by J. curcas to cope with dry and hot conditions. We suggest that J. curcas is more tolerant to hot and dry environments than R. communis but the latter species displays higher photosynthetic efficiency under well-watered and non-stressful conditions. Keywords: abiotic stress, castor bean, photosynthesis, physic nut, acclimation IntroductionPhotosynthetic performance in higher plants under adverse environmental conditions is largely dependent on plant species, which are able to trigger distinct adaptive mechanisms to deal with specific stressful conditions (Cousins et al., 2014). Plants display a set of acclimation strategies to maintain adequate photosynthesis rates in response to abiotic stress-inducers such as high temperature, drought and high light levels (Liu and Huang 2008;Chaves et al., 2009;Gonzalez-Cruz and Pastenes, 2012). To reach their potential or maximum photosynthesis, plants employ a fine metabolic coordination involving several inter-related processes, especially a close balance between photochemical activity and Calvin cycle reactions (Goh at al., 2012).Abiotic stresses are able to disturb this balance, and affect especially CO 2 assimilation due to stomatal and biochemical limitations (Adams III et al., 2013). The degree of preservation of adequate synchrony between light harvest, energy conversion in photosystems and CO 2 assimilation, under stress conditions, is speciesdependent and important to plant productivity (Athanasiou et al., 2010;Kramer and Evans, 2011;Murchie and Niyogi, 2011;Yamori et al., 2014).In general, native species are able to survive un...

“…Several studies (e.g. Achten et al, 2010;FACT Foundation, 2010;Becker and Makkar, 2008;Kumar and Sharma, 2008;Gübitz et al, 1999) claim that jatropha can be grown in low-quality lands (or so called marginal lands) where other crops cannot be grown. Below we discuss several cases considering byproducts markets, climate change benefits and utilization of low-quality lands.…”

“…One of such feedstock plants of contemporary importance is Jatropha curcas linnaeus. Jatropha curcas is a drought resistant perennial species of flowering plants in the spurge family Euphorbiaceous that is native to the American tropics most likely Mexico and Central American (Achten et al, 2010). It is planted in the tropical and subtropical region around the World, becoming naturalized in some area.…”
