“…Cutler (1976) and Patel (1965) point out that taxon identification based on root wood anatomy is not an easy task even for experienced wood anatomists and put emphasis on the difficulties represented by root wood studies due to the root system complexity. Legume root anatomy offers evidence for quite variable structures (Basconsuelo et al 2011). Our findings on the root and stem anatomy of the species studied correspond with the previous investigations regarding the roots and stems of certain genera of the Papilionoideae (Metcalfe and Chalk 1950, Basconsuelo et al 2011, Celep et al 2011, Kahraman et al 2014.…”

“…The root and stem transverse sections of the species analyzed reveal that some anatomical characters are taxonomically important for distinguishing them from each other. Ray parenchyma cells are evolved to translocate nutrients radially between the phloem and the xylem (Basconsuelo et al 2011). Rays in roots of the Papilionoideae are composed of 1-12-rowed cells but frequently 2-3 (Metcalfe and Chalk 1950).…”

Lathyrus L. (Papilionoideae, Fabaceae) is considered economically, ecologically, and genetically among the most significant genera of the flowering plants having its centre of diversity in Southwest Asia where Turkey is located. The anatomical and micromorphological characteristics of species of the genus Lathyrus have been reported in only a few studies. Thus, in the present study, comparative anatomy and leaf epidermal micromorphology of L. cassius Boiss., L. chloranthus Boiss. & Balansa, L. cicera L., L. hirsutus L., and L. sativus L. belonging to the section Lathyrus of this genus are comprehensively investigated by light and scanning electron microscopy so as to assess the taxonomic importance of anatomical and micromorphological characters in species separation. The results obtained reveal that some anatomical and micromorphological characters have proved useful for discrimination at the species level. Anatomical and micromorphological properties of taxonomic significance are as follows: the number of ray rows in the root, the outline of the stem in transverse section, the ratio of the wing length to the stem diameter, the number of vascular bundles in each wing, the shape of leaf epidermal cells, the pattern of their anticlinal walls, and the presence/absence of trichomes on the leaf.

“…Previous studies of vessel scaling have sampled either intensively within species or broadly across the woody plants (Anfodillo et al 2006;Weitz et al 2006;Coomes et al 2007;Mencuccini et al 2007;Nygren and Pallardy 2008;Sperry et al 2008;Terrazas et al 2008;Fan et al 2009;Petit and Anfodillo 2011;Olson and Rosell 2013). Particular vessel diameters or ranges of diameters are often cited as potentially diagnostic of species or clades (IAWA 1989;Herendeen and Miller 2000;Lens et al 2005Lens et al , 2009Basconsuelo et al 2011). Moreover, many quantitative features in organisms are often more similar among closely related species than distantly related ones, a pattern often referred to as phylogenetic signal or "inertia" (Hansen and Martins 1996;Blomberg et al 2003;Revell 2010).…”

Variation in average xylem vessel diameter across species has important functional consequences, but the causes of this variation remain unclear. Average vessel diameter is known to scale with stem size within and across species. Vessel diameter also seems to differ between clades and across environments, with dryland plants having narrower, more cavitation-resistant vessels. As a result, it is not clear to what extent phylogenetic affinity and environment are associated with differences in the vessel diameter-stem size relationship.Methodology. With linear models and correlations, we explored the influence of environment and phylogeny on the vessel diameter-stem diameter relationship in a molecular phylogenetic context across 83 species in four families spanning desert to rain forest in the Americas, Africa, Asia, and Madagascar.Pivotal results. Mean species vessel diameter was strongly predicted by trunk diameter (slope ∼0.33), and this slope was not affected by either phylogenetic affinity or environment. Clades differed only slightly in mean vessel diameter when controlling for stem size, and there was no tendency for plants of moist environments to have wider vessels. Of four climate indexes, only the temperature index contributed to explaining vessel diameter, although very weakly. Conclusions.Our results are congruent with models suggesting that natural selection should maximize vessel conductivity while minimizing cavitation risk via vessel taper in the context of conductive path length. Because neither environment nor phylogeny contributed to explaining vessel diameter-stem diameter scaling across species, our results appear congruent with the notion that selection favoring cavitation resistance via narrow vessels should lead to shorter statures independently of ancestry or habitat. The repeated finding of narrow vessels in dryland plants might therefore reflect the smaller average stem size of plants in drylands rather than the plants having vessels that are narrow for their stem diameters.

“…Root growth and development was indeed observed to result in the formation of thicker cell walls in the central part, improving the mechanical strength, flexibility, and storage capacity of the roots (Raven et al, 2000; Kraus and Bascunsuelo, 2009). It can also not be excluded that a part of the structural variations between the fresh and initially calcified roots are due to their different origins (tree vs. unknown shrubs, respectively), as every plant species can display slightly distinctive root morphological features (e.g., Basconsuelo et al, 2011).…”

Multiple stages of plant root calcification deciphered by chemical and micromorphological analyses

Rhizoliths, that is, roots fossilized by secondary carbonates, have been known for ages and are increasingly used for paleoenvironmental reconstructions. However, knowledge about their formation mechanisms remains limited. This study reports the mineralogical and chemical characterization of rhizoliths at different stages of mineralization and fossilization in the Late Pleistocene loess–paleosol sequence of Nussloch (SW Germany). Scanning electron microscopy coupled with elemental mapping and 13C solid‐state nuclear magnetic resonance were used to concomitantly characterize the mineral and organic matter of the rhizoliths. These joint analyses showed for the first time that large rhizoliths are not necessarily remains of single large roots but consist of numerous microrhizoliths as remains of fine roots, formed mainly by calcium carbonates with only low amounts of Mg and Si. They further revealed that the precipitation of secondary carbonates occurs not only around, but also within the plant root and that fossilization leads to the selective preservation of recalcitrant root biopolymers—lignin and suberin. The precipitation of secondary carbonates was observed to occur first around fine roots, the epidermis acting as a first barrier, and then within the root, within the cortex cells, and even sometimes around the phloem and within the xylem. This study suggests that the calcification of plant roots starts during the lifetime of the plant and continues after its death. This has to be systematically investigated to understand the stratigraphic context before using (micro)rhizoliths for paleoenvironmental reconstructions in terrestrial sediments.
