R.Br., Corydalis incisa (Thunb.) Pers., and Chelidonium majus L. var. asiaticum (Hara) Ohwi., eight isoquinoline alkaloid compounds, i.e., protopine, allocryptopine, sanguinarine, chelerythrine, coryincine, (±)-corynoline, (+)-chelidonine, and (±)-stylopine, were isolated. Furthermore, their structures were spectroscopically determined. Among them, the absolute structure of coryincine was directly determined by X-ray crystallography for the first time. Seven compounds showed larvicidal activity in the mosquito Culex pipiens pallens Coquillett (1898), with corynoline, chelidonine, and stylopine showing particular activity even at low concentrations (1 ppm). In an antifungal test against rice blast fungus, Pyricularia oryzae Cavara involving six compounds, sanguinarine and chelerythrine exhibited almost the same excellent level of activity as isoprothiolane. The toxicity of the M. cordata extract to the fish Oryzias latipes Temminck & Schlegel (1846) was weaker than that of nicotine, which suggests that the fish toxicity of sanguinarine and chelerythrine are low. We believe that these aromatic quaternary benzo[c]phenanthridine alkaloids, especially sanguinarine and chelerythrine, are potentially highly suited as new treatments against the blast fungi and mosquito larvae in aquatic environments, including paddy fields, because of their efficacy and low fish toxicity.

  • The Developmental and Genetic Bases of Apetaly in Bocconia Frutescens
    Arango‑Ocampo et al. EvoDevo (2016) 7:16 DOI 10.1186/s13227-016-0054-6 EvoDevo RESEARCH Open Access The developmental and genetic bases of apetaly in Bocconia frutescens (Chelidonieae: Papaveraceae) Cristina Arango‑Ocampo1, Favio González2, Juan Fernando Alzate3 and Natalia Pabón‑Mora1* Abstract Background: Bocconia and Macleaya are the only genera of the poppy family (Papaveraceae) lacking petals; how‑ ever, the developmental and genetic processes underlying such evolutionary shift have not yet been studied. Results: We studied floral development in two species of petal-less poppies Bocconia frutescens and Macleaya cordata as well as in the closely related petal-bearing Stylophorum diphyllum. We generated a floral transcriptome of B. frutescens to identify MADS-box ABCE floral organ identity genes expressed during early floral development. We performed phylogenetic analyses of these genes across Ranunculales as well as RT-PCR and qRT-PCR to assess loci- specific expression patterns. We found that petal-to-stamen homeosis in petal-less poppies occurs through distinct developmental pathways. Transcriptomic analyses of B. frutescens floral buds showed that homologs of all MADS-box genes are expressed except for the APETALA3-3 ortholog. Species-specific duplications of other ABCE genes inB. frute- scens have resulted in functional copies with expanded expression patterns than those predicted by the model. Conclusions: Petal loss in B. frutescens is likely associated with the lack of expression of AP3-3 and an expanded expression of AGAMOUS. The genetic basis of petal identity is conserved in Ranunculaceae and Papaveraceae although they have different number of AP3 paralogs and exhibit dissimilar floral groundplans.

  • Isolation and Identification of Alkaloids from Macleaya Microcarpa by UHPLC–Q-TOF-MS and Their Cytotoxic Activity in Vitro, An
    Sai et al. BMC Chemistry (2020) 14:5 https://doi.org/10.1186/s13065-020-0660-1 BMC Chemistry RESEARCH ARTICLE Open Access Isolation and identifcation of alkaloids from Macleaya microcarpa by UHPLC– Q-TOF-MS and their cytotoxic activity in vitro, antiangiogenic activity in vivo Chunmei Sai1,2, Jian’an Wang1, Binjie Li3, Lin Ding1, Huiyun Wang1, Qibao Wang1, Huiming Hua3, Fangpeng Zhang2 and Qiang Ren1* Abstract Background: Extensive bioactivities of alkaloids from the genus Macleaya (Macleaya cordata (Willd.) R. Br. and Macleaya microcarpa (Maxim.) Fedde) have been widely reported, as well as more and more concerned from the sci- entifc communities. However, systematic research on the phytochemical information of M. microcarpa is incomplete. The aim of this study was to rapidly and conveniently qualitative analyze alkaloids from M. microcarpa by ultra-perfor- mance liquid chromatography/quadrupole-time-of-fght mass spectrometry (UHPLC–Q-TOF-MS) using accurate mass weight and characteristic fragment ions, furthermore separate and identify the main alkaloids, test antitumor activity in vitro and antiangiogenic activity in vivo. Results: A total of 14 alkaloids from fruits of M. microcarpa were identifed by UHPLC–Q-TOF-MS, including 5 pro- topines, 2 benzophenanthridines, 1 dimer, 1 dihydrobenzophenanthridines and 5 unknown structure compounds. Two major alkaloids were isolated by various column chromatographic methods. Their structures were determined by NMR data and related literatures. The two major alkaloids were evaluated for intro cytotoxic activities against HL-60, MCF-7, A-549, and in vivo antiangiogenic activity using transgenic zebrafsh. Conclusions: Current qualitative method based on UHPLC–Q-TOF-MS technique provided a scientifc basis for isola- tion, structural identifcation, and in vitro or in vivo pharmacological further study of alkaloids from M.

The list was compiled with input from nursery and landscape professionals, Cooperative Extension personnel, and Master Gardeners in Northern N.J. Realizing that no plant is deer proof, plants in the Rarely Damaged, and Seldom Rarely Damaged categories would be best for landscapes prone to deer damage. Plants Occasionally Severely Damaged and Frequently Severely Damaged are often preferred by deer and should only be planted with additional protection such as the use of fencing, repellents, etc. Success of any of these plants in the landscape will depend on local deer populations and weather conditions.

  • Influence of Different Elicitors on BIA Production in Macleaya Cordata
    www.nature.com/scientificreports OPEN Infuence of diferent elicitors on BIA production in Macleaya cordata Peng Huang1,2,7, Liqiong Xia3,7, Li Zhou1,7, Wei Liu1,4, Peng Wang1, Zhixing Qing5* & Jianguo Zeng1,6* Sanguinarine (SAN) and chelerythrine (CHE) have been widely used as substitutes for antibiotics for decades. For a long time, SAN and CHE have been extracted from mainly Macleaya cordata, a plant species that is a traditional herb in China and belongs to the Papaveraceae family. However, with the sharp increase in demand for SAN and CHE, it is necessary to develop a new method to enhance the supply of raw materials. Here, we used methyl jasmonate (MJ), salicylic acid (SA) and wounding alone and in combination to stimulate aseptic seedlings of M. cordata at 0 h, 24 h, 72 h and 120 h and then compared the diferences in metabolic profles and gene expression. Ultimately, we found that the efect of using MJ alone was the best treatment, with the contents of SAN and CHE increasing by 10- and 14-fold, respectively. However, the increased SAN and CHE contents in response to combined wounding and MJ were less than those for induced by the treatment with MJ alone. Additionally, after MJ treatment, SAN and CHE biosynthetic pathway genes, such as those encoding the protopine 6-hydroxylase and dihydrobenzophenanthridine oxidase enzymes, were highly expressed, which is consistent with the accumulation of SAN and CHE. At the same time, we have also studied the changes in the content of synthetic intermediates of SAN and CHE after elicitor induction.

Jurassic NLR: conserved and dynamic evolutionary features of the atypically ancient immune receptor ZAR1 Hiroaki Adachi1, Toshiyuki Sakai1, Jiorgos Kourelis1, Jose L. Gonzalez Hernandez2, Abbas Maqbool1 and Sophien Kamoun1* 1The Sainsbury Laboratory, University of East Anglia, Norwich Research Park, NR4 7UH, Norwich, UK 2Agronomy, Horticulture and Plant Sciences Department, South Dakota State University, Brookings, South Dakota, US *For correspondence: [email protected] ABSTRACT In plants, NLR immune receptors generally exhibit hallmarks of rapid evolution even at the intraspecific level. We reconstructed the evolutionary history of ZAR1, an atypically conserved NLR that traces its origin to early flowering plant lineages ~220 to 150 million years ago (Jurassic period). Ortholog sequence analyses revealed highly conserved features of ZAR1, including regions for pathogen effector recognition, intramolecular interactions and cell death activation. This uncovered a new conserved surface on the ZAR1 resistosome underside that is required for cell death induction. Throughout its evolution, ZAR1 acquired novel features, such as a C-terminal integration of a thioredoxin-like domain. ZAR1 duplicated into two paralog families, which underwent distinct evolutionary paths. We conclude that ZAR1 stands out among angiosperm NLRs for having experienced relatively limited gene duplication and expansion throughout its deep evolutionary history. Nonetheless, ZAR1 did also give rise to non-canonical NLR proteins with integrated domains and degenerated molecular features.

  • Insights Into Triterpene Synthesis and Unsaturated Fatty-Acid Accumulation Provided by Chromosomal- Level Genome Analysis of Akebia Trifoliata Subsp
    Huang et al. Horticulture Research (2021) 8:33 Horticulture Research https://doi.org/10.1038/s41438-020-00458-y www.nature.com/hortres ARTICLE Open Access Insights into triterpene synthesis and unsaturated fatty-acid accumulation provided by chromosomal- level genome analysis of Akebia trifoliata subsp. australis Hui Huang 1,2,JuanLiang1,QiTan1,LinfengOu1, Xiaolin Li3, Caihong Zhong1, Huilin Huang1, Ian Max Møller 4, Xianjin Wu1 and Songquan Song1,5 Abstract Akebia trifoliata subsp. australis is a well-known medicinal and potential woody oil plant in China. The limited genetic information available for A. trifoliata subsp. australis has hindered its exploitation. Here, a high-quality chromosome- level genome sequence of A. trifoliata subsp. australis is reported. The de novo genome assembly of 682.14 Mb was generated with a scaffold N50 of 43.11 Mb. The genome includes 25,598 protein-coding genes, and 71.18% (485.55 Mb) of the assembled sequences were identified as repetitive sequences. An ongoing massive burst of long terminal repeat (LTR) insertions, which occurred ~1.0 million years ago, has contributed a large proportion of LTRs in the genome of A. trifoliata subsp. australis. Phylogenetic analysis shows that A. trifoliata subsp. australis is closely related to Aquilegia coerulea and forms a clade with Papaver somniferum and Nelumbo nucifera, which supports the well-established hypothesis of a close relationship between basal eudicot species. The expansion of UDP-glucoronosyl 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; and UDP-glucosyl transferase gene families and β-amyrin synthase-like genes and the exclusive contraction of terpene synthase gene families may be responsible for the abundant oleanane-type triterpenoids in A.

Equal contribution. y Received: 30 October 2020; Accepted: 3 December 2020; Published: 7 December 2020 Abstract: The TDP1 (tyrosyl-DNA phosphodiesterase 1) enzyme removes the non-specific covalent intermediates between topoisomerase I and DNA, thus playing a crucial role in preventing DNA damage. While mammals possess only one TDP1 gene, in plants two genes (TDP1α and TDP1β) are present constituting a small gene subfamily. These display a different domain structure and appear to perform non-overlapping functions in the maintenance of genome integrity. Namely, the HIRAN domain identified in TDP1β is involved in the interaction with DNA during the recognition of stalled replication forks. The availability of transcriptomic databases in a growing variety of experimental systems provides new opportunities to fill the current gaps of knowledge concerning the evolutionary origin and the specialized roles of TDP1 genes in plants.
