“…1C). The presence of stomata on mericarps is uncommon, although it has been previously reported (e.g., in Bauhinia and Eschscholzia) (Jernstedt and Clark, 1979;Rugenstein and Lersten, 1981).…”

Terpenoids are a large and diverse class of specialized metabolites that are essential for the growth and development of plants, and have tremendous industrial applications. The mericarps of Coriandrum sativum L. (coriander) produce an essential oil (EO) rich in monoterpenes, volatile C10 terpenoids. To investigate EO metabolism, the transcriptome of coriander mericarps, at three developmental stages (early, mid, late) was sequenced via Illumina technology and a transcript library was produced. To validate the usability of the transcriptome sequences, two terpene synthase candidate genes, CsγTRPS and CsLINS, encoding 558 and 562 amino acid proteins were expressed in bacteria, and the recombinant proteins purified by Ni-NTA affinity chromatography. The 65.16 (CsγTRPS) and 65.91 (CsLINS)kDa recombinant proteins catalyzed the conversion of geranyl diphosphate, the precursor to monoterpenes, to γ-terpinene and (S)-linalool, respectively, with apparent Vmax and Km values of 2.24±0.16 (CsγTRPS); 19.63±1.05 (CsLINS)pkat/mg and 66.25±13 (CsγTRPS); 2.5±0.6 (CsLINS)μM, respectively. Together, CsγTRPS and CsLINS account for the majority of EO constituents in coriander mericarps. Investigation of the coriander transcriptome, and knowledge gained from these experiments will facilitate future studies concerning essential and fatty acid oil production in coriander. They also enable efforts to improve the coriander oils through metabolic engineering or plant breeding.

“…. The petals, stamens, and gynoecium in certain species bear an unusual kind of inflated, bifid, multicellular trichome, in addition to the more common filamentous, uniseriate, multicellular hairs found in many Bauhinia species (Rugenstein & Lersten, 1981). This inflated bifid trichome has been overlooked in most compendia of hair-types although Metcalfe & Chalk (1950), and Uphof (1962) reiterated the original notation of Solereder ( 1908) that 'boat-shaped' trichomes, possibly secretory in nature, were present on leaves of B. bongardii Steud.…”

TUCKER, S. C., RUGENSTEIN, S. R. & DERSTINE, K. S., 1984. Inflated trichomes in flowers of Bauhinia (Leguminosae: Caesalpinioideae). An unusual kind of bifid multicellular inflated trichome is reported to occur on floral organs of II species of Bauhinia (Leguminosae‐Caesalpinioideae), They occur on sepals, petals, stamens, carpels, receptacle, leaves, and stems, but not on all organs in each species. Their development in B. malabarica is described.

“…SEM micrographs are given in Figure 1. The micrographs of sample PP20 show that its surface is embossed and smooth with several pores which are attributed to stomata (Rugenstein and Lersten, 1981). SEM images of sample PP120 are characterized by an ordered system of dead cells of the covering tissue.…”

Production of high-performance lead(II) ions adsorbents from pea peels waste as a sustainable resource

et al. 2020

This research deals with a highly efficient, selective, low-cost, and recyclable adsorbent for the fast removal of lead (Pb)(II) ions from aqueous solutions, and an investigation of the related adsorption mechanisms. Three types of materials were prepared from pea peels waste using simple, energy-efficient and environmentally friendly treatment. Obtained adsorbents were characterized by elemental analysis, infrared spectroscopy, scanning electron microscopy, Boehm titration, and the main parameters were determined. The highest adsorption capacity was observed for the biochar prepared by heating of pea peels at 600°C for 30 minutes. The uptake of Pb(II) ions on pea peels-derived samples was examined as a function of pH, contact time, and initial Pb2+ concentration. Obtained results from adsorption experiments of Pb(II) ions on the biochar surface indicate high adsorption capacity, and the possibility of its preconcentration and selective removal in the presence of zinc(II) and cadmium(II) ions. This confirms a potential application of such materials in water remediation.
