Dying of thirst: Osmoregulation by a hawkmoth pollinator in response to variability in ambient humidity and nectar availability.
Dahake A, Persaud SG, Jones MN, Goyret J, Davidowitz G, Raguso RA. Dahake A, et al. J Insect Physiol. 2024 Dec;159:104700. doi: 10.1016/j.jinsphys.2024.104700. Epub 2024 Sep 8. J Insect Physiol. 2024. PMID: 39255897
Moths fed synthetic Datura wrightii nectar, synthetic Agave palmeri nectar, or water, maintained osmolality within a healthy range of 350-400mmol/kg. The same was true for moths fed authentic floral nectars from Datura and Agave plants, although moths consume …

Apoptotic potential role of Agave palmeri and Tulbaghia violacea extracts in cervical cancer cells.
Mthembu NN, Motadi LR. Mthembu NN, et al. Mol Biol Rep. 2014 Sep;41(9):6143-55. doi: 10.1007/s11033-014-3493-y. Epub 2014 Jul 4. Mol Biol Rep. 2014. PMID: 24993114
In South Africa, plants used to treat cancer are rare even though majority of our population continue to put their trust in traditional medicine. In this study we aimed to screen Agave palmeri (AG) and Tulbaghia violacea (TV) for potential role in inducing cell deat …

Multimodal floral signals and moth foraging decisions.
Riffell JA, Alarcón R. Riffell JA, et al. PLoS One. 2013 Aug 21;8(8):e72809. doi: 10.1371/journal.pone.0072809. eCollection 2013. PLoS One. 2013. PMID: 23991154 Free PMC article.
METHODOLOGY/PRINCIPAL FINDINGS: Using M. sexta and the floral traits of two important nectar resources in southwestern USA, Datura wrightii and Agave palmeri, we examined the relative importance of olfactory and visual signals. Natural visual and olfactory cues from …

Novel microsatellite loci for Agave parryi and cross-amplification in Agave palmeri (Agavaceae).
Lindsay DL, Edwards CE, Jung MG, Bailey P, Lance RF. Lindsay DL, et al. Am J Bot. 2012 Jul;99(7):e295-7. doi: 10.3732/ajb.1200033. Epub 2012 Jul 2. Am J Bot. 2012. PMID: 22753814 Free article.
PREMISE OF THE STUDY: To examine the foraging behavior of nectarivorous bats in southeastern Arizona, we developed microsatellite primers in Agave parryi. These markers were also tested for cross-amplification and applicability to assess patterns of genetic diversity and s …

Neural correlates of behavior in the moth Manduca sexta in response to complex odors.
Riffell JA, Lei H, Hildebrand JG. Riffell JA, et al. Proc Natl Acad Sci U S A. 2009 Nov 17;106(46):19219-26. doi: 10.1073/pnas.0910592106. Epub 2009 Nov 11. Proc Natl Acad Sci U S A. 2009. PMID: 19907000 Free PMC article.
We used gas chromatography coupled with multiunit neural-ensemble recording to identify key odorants from flowers of two important nectar resources, the desert plants Datura wrightii and Agave palmeri, that elicited responses from individual antennal-lobe neurons. N …

Floral trait associations in hawkmoth-specialized and mixed pollination systems: Datura wrightii and Agave spp. in the Sonoran Desert.
Riffell JA, Alarcón R, Abrell L. Riffell JA, et al. Commun Integr Biol. 2008;1(1):6-8. doi: 10.4161/cib.1.1.6350. Commun Integr Biol. 2008. PMID: 19704447 Free PMC article.
The southernmost agave, Agave palmeri (Agavacea), exhibits floral traits typical of bat pollination, whereas the northernmost species, Agave chrysantha (Agavacea), exhibits mixed floral traits which appear to be adapted to insects, and to a lesser exte …

Reproductive biology of Datura wrightii: the benefits of a herbivorous pollinator.
Bronstein JL, Huxman T, Horvath B, Farabee M, Davidowitz G. Bronstein JL, et al. Ann Bot. 2009 Jun;103(9):1435-43. doi: 10.1093/aob/mcp053. Epub 2009 Mar 14. Ann Bot. 2009. PMID: 19287014 Free PMC article.
