“…To compare total alkaloid concentrations across tissue types in each species, we used linear mixed effects models (LMM) with tissue type (leaf, flower, stem, and pollen) and site as fixed effects (for L. sulphureus , which came from a single site, tissue was the only fixed effect), an interaction between fixed effects of site and tissue, and individual as a random effect. The secondary chemistry profiles of lupine are known to vary systematically between sites (Carey and Wink, ; Muzquiz et al., ; Adler and Kittelson, ; Cook et al., ). While the primary goal of our study was to compare alkaloid patterns between tissues within individuals, we were still interested in capturing any between site variation in the populations that we studied.…”

Premise Optimal defense theory predicts that selection should drive plants to disproportionally allocate resources for herbivore defense to tissues with high fitness values. Because pollen's primary role is the transport of gametes, plants may be expected to defend it from herbivory. However, for many animal‐pollinated plants, pollen serves a secondary role as a pollinator reward. These dual roles may present a conflict between selection to defend pollen from herbivores and selection to reward pollinators. Here, we investigate whether pollen secondary chemistry in three pollen‐rewarding Lupinus species better reflects the need to defend pollen or reward pollinators. Methods Lupinus (Fabaceae) species are nectarless, pollen‐rewarding, and produce defensive quinolizidine and/or piperidine alkaloids throughout their tissues. We used gas chromatography to identify and quantitate the alkaloids in four aboveground tissues (pollen, flower, leaf, stem) of three western North American lupines, L. argenteus, L. bakeri, and L. sulphureus, and compared alkaloid concentrations and composition among tissues within individuals. Results In L. argenteus and L. sulphureus, pollen alkaloid concentrations were 11–35% of those found in other tissues. We detected no alkaloids in L. bakeri pollen, though they were present in other tissues. Alkaloid concentrations were not strongly correlated among tissues within individuals. We detected fewer alkaloids in pollen compared to other tissues, and pollen contained no unique alkaloids. Conclusions Our results are consistent with the hypothesis that, in these pollen‐rewarding species, pollen secondary chemistry may reflect the need to attract and reward pollinators more than the need to defend pollen from herbivory.

Lupins (Lupinus spp.) are legumes with high relevance for the sustainability of agricultural systems as they improve the soil quality, namely, through the fixation of atmospheric nitrogen, and have good adaptability to different climates and soil conditions. Besides, they possess high nutritive value, especially due to the high protein content of the seeds. Nevertheless, the plants' productivity and metabolism can be influenced by the genotype, the edaphoclimatic conditions, and the sowing practices. In this work, the effect of edaphoclimatic conditions and sowing dates on the productivity, nutritional factors, and alkaloids of the seeds of L. albus cv. Estoril, L. angustifolius cv. Tango, and L. luteus cv. Cardiga was evaluated. High variability in the seeds and protein productions, nutritional traits, and alkaloid content related to the species was observed, along with a significant effect of the location. Lupinus albus cv. Estoril showed a good compromise between productivity and low alkaloid content, being an interesting genotype for food and feed use in the conditions of this trial.

“…These findings demonstrated that one chemotype is most divergent from the other chemotypes of L. sulphureus, suggesting that it represents an unresolved taxon, possibly an undescribed lupine species. 66 In addition, the other chemotypes were found to represent different genetic groups/races. The authors hypothesized that the molecular diversity may in part explain the diversity of chemotypes observed in L. sulphureus.…”

Poisonous plants cause large losses to the livestock industry through death, reduced production efficiency, reproductive dysfunction, and compromised harvesting of rangeland and pasture forages. Research investigating poisonous plants is complex because there are hundreds of genera of toxic plants representing thousands of species. To investigate the effects of poisonous plants on livestock, a clear understanding of the taxonomic identity of the plant and the ability to collect the plant in sufficient quantities for scientific studies is required. Subsequently, the active principles must be defined and investigated in the taxa of interest to better predict risk and make recommendations to reduce losses. Herbaria are collections of preserved plant specimens and are an important resource in poisonous plant research. Voucher specimens have often been used in the identification of the plant for the experimental reproduction of suspected livestock poisoning associated with a spontaneous case. More recently, herbarium specimens have been used to investigate the chemical composition of toxic plants as well as the distribution of different chemotypes over the landscape. The primary purpose of this review is to highlight the chemical analysis of herbarium specimens in poisonous plant research.
