Data for: Roots originating from different shoot parts are functionally different in running bamboo, Phyllostachys glauca
<p>Running bamboos are a group of clonal plants exhibiting rapid and widespread expansion. They possess two root subsystems, arising from different shoot parts, culm roots and rhizome roots. To date, it remains unclear what the functional differences are between the two root subsystems and what their relation is to the remarkably competitive ability of running bamboos. A typical running bamboo, <em>Phyllostachys glauca</em>, which dominates in a highly heterogenous habitat of limestone hills, was sampled to compare the morphology, architecture, anatomy, chemical composition, mechanics, and nutrient acquisition of the two root subsystems to explore their differences in functional traits. Compared with rhizome roots, culm roots possessed greater tensile strength, modulus of elasticity, stele diameter to root diameter ratio, root tissue density, root length density, rooting depth, basal diameter of shoot-borne roots, and more lignified cells. Culm roots also had a higher phosphorus (P) concentration (>0.4 mg g<sup>-1</sup>), which was nearly twice that of rhizome roots. By contrast, rhizome roots exhibited a greater specific root area, specific root length, cortex thickness to root radius ratio, total branch order, and greater P-uptake capacity than culm roots. Our findings revealed distinct differences in functional traits between culm roots and rhizome roots in <em>P. glauca</em>. Culm roots are considered to primarily provide anchorage, but also function in resource acquisition and nutrient storage, while rhizome roots mainly play a role in resource acquisition. Except for the anchorage and resource acquisition of culm roots, the extra resource acquisition by rhizome roots and the high concentration of a limiting nutrient (P) in culm roots enhance the performance in a highly heterogenous habitat which offers a physiological explanation for <em>P. glauca</em> dominating on limestone hills. The functional differentiation between culm roots and rhizome roots provides insight into the mechanism underpinning the remarkable expansion of running bamboos and offers a new perspective to explain the strong competitive ability of clonal plants with dimorphic roots.</p>
Contents and isotope carbon compositions (δ13C) of main biochemical fractions in organs at different growth stages in Phyllostachys edulis
<p><em><span>Phyllostachys edulis</span></em><span> is a spectacularly fast-growing species that completes its height growth within </span><span>two</span><span> months after the shoot emerges </span><span>without producing leaves</span><span> (fast-growing period, FGP). This phase was considered heterotrophic, the carbon necessary for the growth being transferred from the mature culms via the rhizomes, although previous studies observed key enzymes and anatomical features related to C<sub>4</sub>-carbon fixation in developing culms. </span><span>We tested whether C<sub>4</sub>-photosynthesis or dark-CO2 fixation through anaplerotic reactions significantly contributes to the FGP, resulting in differences in the natural abundance of </span><span>δ<sup>13</sup>C</span><span> in bulk organic matter and organic compounds. Further, pulse-<sup>13</sup>CO<sub>2</sub>-labelling was performed on developing culms, either from the surface or from the internal hollow, to ascertain whether significant CO<sub>2</sub> fixation occurs in developing culms.</span><span> δ<sup>13</sup>C of</span><span> young </span><span>shoots and developing culms were higher (-26.3–-26.9‰) </span><span>compared to all organs of mature bamboos (-28.4</span><span>–</span><span>-30.1</span><span>‰). </span>Developing culms contained chlorophylls, most observed in the skin tissues. After <span>pulse-<sup>13</sup>CO<sub>2</sub>-labelling, t</span>he polar fraction extracted from the skin tissues was slightly enriched in <sup><span>13</span></sup><span>C, </span>and only a weak <sup><span>13</span></sup><span>C </span>enrichment was observed in inner tissues<span>. Main carbon source sustaining the FGP was not assimilated by the developing culm, while a </span><span>limited anaplerotic fixation of respired CO<sub>2</sub></span><span> cannot be excluded and is </span>more likely than <span>C<sub>4</sub>-</span>photosynthetic carbon fixation<span>.</span></p>

Chloroplast genome of Phyllostachys glauca
<p><span><i>Phyllostachys glauca</i> is a dominant species in limestone mountains endemic to China. Here, we characterized its complete chloroplast genome. It is a circular DNA molecule of 139689 bp in length, including a pair of 21798 bp inverted repeats (IRs), a 12872 bp small single-copy (SSC) region and an 83221 bp large single-copy (LSC) region. The total GC content of <i>P. glauca</i> chloroplast genome was 38.9%, and it encodes a total of 137 functional genes, including 89 protein-coding genes, 40 tRNA genes, and 8 rRNA genes. The phylogenetic analysis shows that <i>P. glauca</i> is highly clustered in the <i>Phyllostachys</i> clade (V), sister to the lineage of <i>P. nigra</i> var. <i>henonis</i> + <i>P. sulphurea</i>.</span></p>
