In this work the protein content and amino acid composition of nutlets of 21 Teucrium taxa (Lamiaceae) from Spain were analysed and their nutritional quality was compared with the minimum values established by the Food and Agriculture Organization of the United Nations (FAO). In addition, the amino acid composition was evaluated as a chemical character to clarify the taxonomic complexity in this genus. METHODS: Amino acid content of nutlets was determined after derivatization with diethyl ethoxymethylenemalonate by high-performance liquid chromatography. Previously, nutlets samples were hydrolysed and incubated in an oven at 110 degrees C for 24 h. KEY RESULTS: The protein content was variable, ranging from 6.4 % in T. dunense to 43.8 % in T. algarbiense. According to the FAO values all taxa contain satisfactory amounts of leucine, threonine and valine and are deficient in lysine. The similarity analysis of Teucrium taxa using amino acid composition data did not clearly reflect the infrageneric classification of this genus. CONCLUSIONS: Annual species, such as T. spinosum, T. aristatum and T. resupinatum showed a better balanced amino acid composition. The dendrogram partly matched with the karyological complexity of Teucrium. No correlation between amino acid composition and habitat has been observed, showing that Teucrium nutlet amino acid composition may not be strongly influenced by the environment.10aAmino Acids10aAmino Acids: Essential10aEvolution: Molecular10aFruit10aNutritive Value10aPhylogeny10aPlant Proteins10aSpecies Specificity10aTeucrium1 aJuan, R1 aPastor, J1 aMillán, F1 aAlaiz, M1 aVioque, J  uhttps://lamiaceae.myspecies.info/content/amino-acids-composition-teucrium-nutlet-proteins-and-their-systematic-significance02996nas a2200361   4500008004100000245013100041210006900172260000800241300001400249490000800263520196600271653002002237653001702257653002102274653002402295653001702319653001902336653001302355653001502368653001202383653001302395653001402408653001402422653001402436653001502450653001102465653001402476653002402490653001302514100001902527700002302546856006502569       2007                        eng d00aStaminal evolution in the genus Salvia (Lamiaceae): Molecular phylogenetic evidence for multiple origins of the staminal lever0 aStaminal evolution in the genus Salvia Lamiaceae Molecular phylo  cJan  a375–3910 v1003 aBackground and Aims The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, the staminal morphology of the various lineages of Salvia and related genera is characterized and an evolutionary interpretation of staminal variation within the tribe Mentheae is presented.Methods Two molecular analyses are presented in order to investigate phylogenetic relationships in the tribe Mentheae and the genus Salvia. The first presents a tribal survey of the Mentheae and the second concentrates on Salvia and related genera. Schematic sketches are presented for the staminal morphology of each major lineage of Salvia and related genera.Key Results These analyses suggest an independent origin of the staminal elongate connective on at least three different occasions within the tribe Mentheae, each time with a distinct morphology. Each independent origin of the lever mechanism shows a similar progression of staminal change from slight elongation of the connective tissue separating two fertile thecae to abortion of the posterior thecae and fusion of adjacent posterior thecae. A monophyletic lineage within the Mentheae is characterized consisting of the genera Lepechinia, Melissa, Salvia, Dorystaechas, Meriandra, Zhumeria, Perovskia and Rosmarinus.Conclusions Based on these results the following are characterized: (1) the independent origin of the staminal lever mechanism on at least three different occasions in Salvia, (2) that Salvia is clearly polyphyletic, with five other genera intercalated within it, and (3) staminal evolution has proceeded in different ways in each of the three lineages of Salvia but has resulted in remarkably similar staminal morphologies.10aDiversification10aDorystaechas10aFloral Evolution10aFloral Nectar Spurs10aIncongruence10aKey Innovation10aLabiatae10aLepechinia10aMelissa10aMentheae10aMeriandra10aPerovskia10aRadiation10aRosmarinus10aSalvia10aSequences10aStaminal Morphology10aZhumeria1 aWalker, Jay, B1 aSytsma, Kenneth, J  uhttp://aob.oxfordjournals.org/cgi/content/abstract/100/2/37503028nas a2200301   4500008004100000245013500041210006900176260000800245300001300253490000800266520210300274653001802377653002102395653001402416653001802430653002202448653001302470653002702483653001202510653001402522653001902536653002402555653003102579653001002610100002602620700002302646856005702669       2007                        eng d00aPopulation genetic structure and hybridization patterns in the Mediterranean endemics Phlomis lychnitis and P. crinita (Lamiaceae)0 aPopulation genetic structure and hybridization patterns in the M  cOct  a735–460 v1003 aBACKGROUND AND AIMS: The historical influence of gene flow and genetic drift after the last glacial phase of the Quaternary Period is reflected in current levels of genetic diversity and population structure of plant species. Moreover, hybridization after secondary contact might also affect population genetic diversity and structure. An assessment was made of the genetic variation and hybrid zone structure in Iberian populations of the Mediterranean Phlomis lychnitis and P. crinita, for which phylogenetic relationships are controversial, and hybridization and introgression are common. METHODS: Allozyme variation at 13 loci was analysed in 1723 individual plants sampled from 35 natural locations of P. lychnitis, P. crinita subsp. malacitana and P. crinita subsp. crinita in southern and eastern Spain. Standard genetic diversity parameters were calculated and patterns of genetic structure in each taxon were tested to fit the equilibrium between gene flow and genetic drift. Individual multilocus genotypes were subjected to Bayesian clustering analysis to estimate hybridization and introgression rates for both geographic regions. KEY RESULTS: Contrasting patterns in the distribution of genetic variation among the three taxa were found. Phlomis lychnitis showed no significant inbreeding, low genetic differentiation among populations and no evidence of isolation by distance. Phlomis crinita subsp. malacitana and P. crinita subsp. crinita showed high levels of genetic structure consistent with a pattern of gene flow-drift equilibrium. Higher instances of hybridization and introgression were detected in locations from southern Spain compared with locations from eastern Spain, matching unimodal and bimodal hybrid zones, respectively. CONCLUSIONS: High instances of historical gene flow, range expansion and altitudinal movement during the Quaternary Period, and lineage sorting can explain the diversity of patterns observed. The results suggest that P. lychnitis is the most differentiated lineage in the group; however, the relationship between the three taxa remains unclear.10aBayes Theorem10aCluster Analysis10aGene Flow10aGenetic Drift10aGenetic Variation10aGenotype10aHybridization: Genetic10aPhlomis10aPhylogeny10aPlant Proteins10aPopulation Dynamics10aSequence Analysis: Protein10aSpain1 aAlbaladejo, Rafael, G1 aAparicio, Abelardo  uhttp://aob.oxfordjournals.org/content/100/4/735.long02598nas a2200193   4500008004100000245013100041210006900172260000800241300001300249490000800262520197300270653002502243653001202268653001402280653001102294100001902305700002302324856005702347       2007                        eng d00aStaminal evolution in the genus Salvia (Lamiaceae): molecular phylogenetic evidence for multiple origins of the staminal lever0 aStaminal evolution in the genus Salvia Lamiaceae molecular phylo  cAug  a375–910 v1003 aBACKGROUND AND AIMS: The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective.
