Introduction. In the discovery of more potent and selective anticancer drugs, the research continually expands and explores new bioactive metabolites coming from diferent natural sources. Gallnuts are a group of very special natural products formed through parasitic interaction between plants and insects. Tough it has been traditionally used as a source of drugs for the treatment of cancerous diseases in traditional and folk medicinal systems through centuries, the anticancer properties of gallnuts are barely systematically reviewed. Objective. To evidence the traditional uses and phytochemicals and pharmacological mechanisms in anticancer aspects of gallnuts, a literature review was performed. Materials and Methods. Te systematic review approach consisted of searching web-based scientifc databases including PubMed, Web of Science, and Science Direct.

We examined the structures of galls and their functional adaptation using various macro- and microscopic techniques. The highly adapted structures include a stalk at the base that is specialized for mechanical support and transport of nutrients for aphids, and a network of vascular bundles which accompanying schizogenous ducts arranged in a way to best support aphid feeding and population growth. There are many circular and semicircular xylems traces in an ensiform gall in cross sectional views, which would provide more nutrition and occupy less space. We infer the evolution trail was fower-like gall, horned gall, circular gall and ensiform gall. And the possible evolutionary trend of the gall was bigger chamber, more stable mechanical supporting, easier for exchanging substance and transporting nutrients. Galls are abnormal outgrowths of plant tissues induced by gall-inducing organisms, which included various par- asitic insects and mites. It is estimated that there are ~4700 diferent species that can induce gall formation under certain conditions1. Te induction of galls is believed to be a result of plant manipulation by gall-inducing agents, and because of this, galls are generally considered as extended structures of the gallicolous organisms2–5.

  • Distribution of Species from the Genus Rhus L. in the Eastern Mediterranean Region and in Southwestern Asia
    ARBORETUM KÓRNICKIE ■ ROCZNIK XXVI — 1982 Kazimierz Browicz Distribution of species from the genus' Rhus L. in the eastern Mediterranean region and in southwestern Asia In the Mediterranean region there occur 3 species from the genus Rhus L., namely Rhus coriaria L., R. pentaphylla (Jacq.) Desf. and R. tri­ partita (Ucria) Grande. While the first one is widely scattered the latter two, originating primarily from North Africa are rather rare or even very rare in southern Europe and southwestern Asia. In Europe they grow only in Sicilia (Tut in, 1968). In southwestern Asia R. pentaphylla is repor­ ted exclusively from northwestern Israel, from rocky shores of Coastal Galilee and the Acco Plain (Zohary, 1972). On the other hand R. tri­ partita has more stands here and the drawing of its range in the region under discussion is possible though not very accurately. Besides the species mentioned above, there occur four species more in the most eastern part of southwestern Asia, in eastern Pakistan, namely: Rhus chinensis Milller, R. mysurensis Heyne ex Wight et Arn., R. punja- bensis Stewart ex Brandis and R. succedana L. (Stewart, 1972). Howe­ ver, data on these stands are so incomplete, that on their basis a descrip­ tion of range maps, even very approximate ones, is impossible. In view of the above only ranges of two species are discussed here — R. coriaria and R. tripartita. 1. RHUS CORIARIA L. An erect shrub with quite thick, scarcely ramified shoots attaining a height of 2-4 m, and rarely more. Even taller ones have been reported from Uzbekistan, from the basin of river Tupalanga (Z a pr j a gae v a, 1964), where R.

  • Molecular Mechanisms of Tannin Accumulation in Rhus Galls And
    www.nature.com/scientificreports OPEN Molecular mechanisms of tannin accumulation in Rhus galls and genes involved in plant-insect Received: 20 November 2017 Accepted: 11 June 2018 interactions Published: xx xx xxxx Hang Chen 1,2, Juan Liu1, Kai Cui1, Qin Lu1, Chao Wang1,3, Haixia Wu1, Zixiang Yang1, Weifeng Ding 1, Shuxia Shao1, Haiying Wang1, Xiaofei Ling1, Kirst King-Jones4 & Xiaoming Chen1,2 For galling aphids and their hosts, tannins are crucial for plant-insect interactions and for protecting the host plant from herbivory. Due to their peculiar chemical characteristics, tannins from plant galls have been used for medical and chemical purposes for more than 2000 years. In this study, hydrolyzable tannin concentrations in galls increased from gall initiation (38.34% on June 21) to maturation (74.79% on August 8), then decreased gradually thereafter (58.83% on October 12). We identifed a total of 81 genes (named as GTS1-81) with putative roles in gallotannin biosynthesis and 22 genes (TS1-22) in condensed tannin biosynthesis. We determined the expression profles of these genes by real-time PCR over the course of gall development. Multiple genes encoding 1-beta-D-glucosyl transferases were identifed, which may play a vital role in gallotannin accumulation in plant galls. This study is the frst attempt to examine the molecular basis for the regulation of tannin accumulation in insect gallnuts. The diferentially expressed genes we identifed may play important roles in both tannin biosynthesis and plant-insect interactions. Plants and insects have co-existed for more than 350 million years1, and in their interactions both have evolved strategies to overcome each other’s defense systems2,3.

They belong to a complex of Rhus species called “lantriscos”, which are used for medicinal applications. The medicinal effects of these species are based on traditional use, however, they require phytochemical research to validate their medicinal properties, as well as structural characterization for their correct identification during the collecting practice and uses. The phytochemical potential of aqueous extracts from R. pachyrrhachis and R. virens was analyzed by the quantification of total phenolic content (TPC), free radical-scavenging potential, and total flavonoids, with a comparison of four drying methods, and some phenolic compounds were identified. Furthermore, the stems and leaves of both species were anatomically characterized to establish a differentiation. R. pachyrrhachis and R. virens showed similar values of phytochemical contents, although the TPC content (0.17 mg of gallic acid equivalent per gram of dry weight, GAE/g DW) was higher in R. virens. The drying method used affected the metabolite contents, and this behavior was related to the species.

  • Plastid Genomes of the North American Rhus Integrifolia-Ovata Complex and Phylogenomic Implications of Inverted Repeat Structural Evolution in Rhus L
    Plastid genomes of the North American Rhus integrifolia-ovata complex and phylogenomic implications of inverted repeat structural evolution in Rhus L. Craig F. Barrett Department of Biology, West Virginia University, Morgantown, WV, USA ABSTRACT Plastid genomes (plastomes) represent rich sources of information for phylogenomics, from higher-level studies to below the species level. The genus Rhus (sumac) has received a significant amount of study from phylogenetic and biogeographic perspectives, but genomic studies in this genus are lacking. Rhus integrifolia and R. ovata are two shrubby species of high ecological importance in the southwestern USA and Mexico, where they occupy coastal scrub and chaparral habitats. They hybridize frequently, representing a fascinating system in which to investigate the opposing effects of hybridization and divergent selection, yet are poorly characterized from a genomic perspective. In this study, complete plastid genomes were sequenced for one accession of R. integrifolia and one each of R. ovata from California and Arizona. Sequence variation among these three accessions was characterized, and PCR primers potentially useful in phylogeographic studies were designed. Phylogenomic analyses were conducted based on a robustly supported phylogenetic framework based on 52 complete plastomes across the order Sapindales. Repeat content, rather than the size of the inverted repeat, had a stronger relative association with total plastome length across Sapindales when analyzed with phylogenetic least squares regression. Variation at the inverted repeat boundary within Rhus was striking, resulting in major shifts and independent gene losses. 10 February 2020 Submitted Specifically, rps19 was lost independently in the R. integrifolia-ovata complex and in Accepted 17 May 2020 Published 16 June 2020 R.
