“…In order to verify to what extend the results are due to phylogenetic relatedness among species, the correlation between variables was also performed using phylogenetic independent contrasts (PICs; Felsenstein 1985). A phylogenetic tree was assembled based on the supertree available in the ''Phylocom'' software (Webb et al 2008) and considering the phylogeny of Fabaceae (Pardo et al 2004). To better understand the multidimensional strategy of the coexisting species, a principal components analysis (PCA) was conducted with all measured morphological and functional variables, using mean values of the variables for each species.…”

Morphological traits and water use strategies in seedlings of Mediterranean coexisting species

The distribution of plants is associated with their different patterns of response to their environment. Mediterranean plants have evolved a number of morphological and physiological adaptations that determine their ability to survive and grow, being an effective water uptake and use important factors for drought resistance. In this article, we evaluated interspecific differences in morphology, biomass allocation, and architectural traits and their relationship with water use strategies in seedlings of seven co-occurring Mediterranean species (Anthyllis cytisoides L., Genista scorpius L. DC., Myrtus communis L., Pistacia lentiscus L., Rosmarinus officinalis L., Spartium junceum L. and Ulex parviflorus Pourr.). The results showed that morphological root features vary among species and they are significantly correlated with root hydraulic conductance and leaf gas exchange variables. Species with high specific root length (SRL) showed a low hydraulic conductance per root length (K RRL ) but high specific hydraulic conductance (K As ). M. communis and P. lentiscus showed the most contrasting water use patterns with respect to the other species studied. The results are not affected when considering phylogenetic relatedness. Thus, the variability observed in root hydraulic properties and leaf gas exchange suggests important mechanisms for understanding species coexistence in water-limited ecosystems.

“…We summarized the relationships within tribe Genisteae based on the phylogenetic information in Pardo et al (2004) and Cristofolini and Feoli-Chiapella (1981), and listed different eriophyoid mite species known from these plants ( Table 2). Lupinus is distantly related to Cystius, and it is therefore not surprising that A. genistae failed to form galls on Lupinus in host specificity tests in Washington.…”

“…However, there seems little doubt that there is a complex of Aceria species on Genisteae, some being perhaps monophagous and some having slightly broader host ranges (feeding on closely related host species) with minor intraspecific variation. (2011) with phylogenetic information from Ainouche et al (2004), Pardo et al (2004) and Feoli & Cristofolini (1981 …”

This paper reports on a collection of eriophyid mites from broom (Cytisus scoparius), gorse (Ulex europaeus), and related plants (Fabaceae: Genisteae) in the western USA, to clarify the taxonomic problems within the "Aceria genistae" complex on different hosts. The mites from U. europaeus and Genista monspessulana, which were previously identified as or suspected to be Aceria genistae, are herein confirmed as Aceria davidmansoni-previously known only from U. europaeus in New Zealand. The mites from Lupinus albicaulis (no galls), Lupinus densiflorus (with gall-like deformities although not true galls), Cytisus striatus and C. scoparius are confirmed as A. genistae (the first three species were used in host specificity tests for A. genistae from C. scoparius and only C. striatus is confirmed as a new host for A. genistae). Another unrelated species, Aculops hussongi Keifer, was found on L. albicaulis in Nisqually, Washington, USA.

“…According to its morphological and phytochemical characters, it is known as a heterogeneous section that does not form a monophyletic group. Because of the molecular data, the species of this section are included in separate groups intermingled with species of other sections and several intersectional hybrids are also present (PARDO et al 2004). This heterogeneity was confirmed also by karyological and palynological data (CANTÓ et al 1997;CUSMA VELARI et al 2003RIZZI LONGO and FEOLI CHIAPELLA 2009).…”

Summary -Genista sericea Wulfen, a northern Illyrian amphi-Adriatic species, presents a certain morphological variability. To clarify whether the genetic variations support the morphological differences among accessions of different geographic origin, analysis of nuclear DNA content and polymorphism of the internal transcribed spacer (ITS) dataset was studied. The variation in nuclear DNA content of G. sericea var. sericea and var. rigida is minimal (2.09 and 2.08 pg/nucleus respectively) and is correlated with equal chromosome numbers in both varieties. Intraspecific variability of the ITS region was studied on 13 accessions of G. sericea, 6 belonging to var. sericea and 7 to var. rigida. These accessions were analyzed in comparison to closely related species already studied. ITS sequences of G. sericea revealed large polymorphism and formed two main clusters. One cluster (6 accessions) comprehends var. sericea of northern Italy, Slovenia and northern Croatia; the other cluster (7 accessions) includes five accessions of var. rigida from southern Croatia and Montenegro and two from the Pollino massif (southern Italy). The later two accessions considerably differed from other accessions of var. rigida. This genetic analysis supports the previous assumptions, which subdivided G. sericea into at least two taxa. On the basis of the results presented, it is here suggested that the subdivision of G. sericea into var. sericea and var. rigida should be maintained.
