Previous work has established that a WGD affects most lineages in the Papilionoideae and occurred sometime after the divergence of the papilionoid and mimosoid clades, but the exact timing has been unknown. -
Final Report
Final Report Final pre-release investigations of the gorse thrips (Sericothrips staphylinus) as a biocontrol agent for gorse (Ulex europaeus) in North America Date: August 31, 2012 Award Number: 10-CA-11420004-184 Report Period: June 1, 2010– May 31, 2012 Project Period: June 1, 2010– May 31, 2012 Recipient: Oregon State University Recipient Contact Person: Fritzi Grevstad Principal Investigator/ Project Director: Fritzi Grevstad Introduction Gorse (Ulex europaeus) is an environmental weed classified as noxious in the states of Washington, Oregon, California, and Hawaii. A classical biological control program has been applied in Hawaii with the introduction of 4 gorse-feeding arthropods, but only two of these (a mite and a seed weevil) have been introduced to the mainland U.S. The two insects that have not yet been introduced include the gorse thrips, Sericothips staphylinus (Thysanoptera: Thripidae), and the moth Agonopterix umbellana (Lepidoptera: Oecophoridae). With prior support from the U.S. Forest Service (joint venture agreement # 07-JV-281), we were able to complete host specificity testing of S. staphylinus on 44 North American plant species that were on the original test plant list. However, following review of the proposed Test Plant List, the Technical Advisory Group on Biocontrol of Weeds (TAG) recommended that we include an additional 18 plant species for testing. In this report, we present host specificity testing and related objectives necessary to bring the program to the implementation stage. Objectives (1) Acquire and grow the additional 18 species of plants recommended by the TAG. (2) Complete host specificity trials for the gorse thrips on the 18 plant species. -

By NORHAYU BINTI ASIB UPM January 2015 Chairman : Professor Dzolkhifli Omar, PhD. Faculty : Agriculture Rotenone found in the crude extract from the roots of Tuba plants is commonly used as a bioinsecticide to control insect pests of horticultural crops. The control obtained on insect pests varies greatly and this could probably be due to the source and process of extraction, toxicant preparation and application in the field. The need to improve the quality of the rotenone as botanical insecticide and to obtain consistent control of insect pest led to the studies with following objectives; 1) to identify the diversity of Tubaplants based on Random Amplified Polymorphic DNA (RAPD) analysis, Internal Transcribe Spacer (ITS) marker and their morphological characteristics, 2) to extract, and characterize bioactive compound rotenone from Tuba plants, 3) to prepare the bio- based emulsion formulation of rotenone extract and 4) to evaluate the insecticidal properties of the emulsion formulation of rotenone against Diamondback moth (DBM). -
Endosamara Racemosa (Roxb.) Geesink and Callerya Vasta (Kosterm.) Schot
Taiwania, 48(2): 118-128, 2003 Two New Members of the Callerya Group (Fabaceae) Based on Phylogenetic Analysis of rbcL Sequences: Endosamara racemosa (Roxb.) Geesink and Callerya vasta (Kosterm.) Schot (1,3) (1,2) Jer-Ming Hu and Shih-Pai Chang (Manuscript received 2 May, 2003; accepted 29 May, 2003) ABSTRACT: Two new members of Callerya group in Fabaceae, Endosamara racemosa (Roxb.) Geesink and Callerya vasta (Kosterm.) Schot, are identified based on phylogenetic analyses of chloroplast rbcL sequences. These taxa joined with other previously identified taxa in the Callerya group: Afgekia, Callerya, and Wisteria. These genera are resolved as a basal subclade in the Inverted Repeat Lacking Clade (IRLC), which is a large legume group that includes many temperate and herbaceous legumes in the subfamily Papilionoideae, such as Astragalus, Medicago and Pisum, and is not close to other Millettieae. Endosamara is sister to Millettia japonica (Siebold & Zucc.) A. Gray, but only weakly linked with Wisteria and Afgekia. KEY WORDS: Endosamara, Callerya, Millettieae, Millettia, rbcL, Phylogenetic analysis. INTRODUCTION Recent molecular phylogenetic studies of the tribe Millettieae have revealed that the tribe is polyphyletic and several taxa are needed to be segregated from the core Millettieae group. One of the major segregates from Millettieae is the Callerya group, comprising species from Callerya, Wisteria, Afgekia, and Millettia japonica (Siebold & Zucc.) A. Gray. The group is considered to be part of the Inverted-Repeat-Lacking Clade (IRLC; Wojciechowski et al., 1999) including many temperate herbaceous legumes. Such result is consistent and supported by chloroplast inverted repeat surveys (Lavin et al., 1990; Liston, 1995) and phylogenetic studies of the phytochrome gene family (Lavin et al., 1998), chloroplast rbcL (Doyle et al., 1997; Kajita et al., 2001), trnK/matK (Hu et al., 2000), and nuclear ribosomal ITS regions (Hu et al., 2002). -

Abstract Plant small RNAs (sRNAs) are important regulatory elements that fine-tune gene expression and maintain genome integrity by silencing transposons. They have critical roles in most pathways involved in plant growth and reproductive development. Reproductive organs of monocots produce abundant phased, small interfering RNAs (phasiRNAs). The 21-nt reproductive phasiRNAs triggered by miR2118 are highly enriched in pre-meiotic anthers, and have not been described in eudicots. -

The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing as endangered or threatened is based on the species’ status considering the five threat factors described in section 4(a)(1) of the Act. These same five factors are considered in any subsequent reclassification or delisting decisions. -

The reddish leaves and stems, primarily of one cultivar, are used to make a commercially important tea which is marketed locally and internationally as ‘rooibos’ or ‘redbush’ tea. In historical times rooibos was collected in the wild. In the twentieth century cultivation of a single cultivar increasingly replaced wild harvest to meet growing demand. Recently, tea from wild forms of the species, which vary significantly in growth form and reproductive strategy, has been marketed by small-scale farmers in Wupperthal and on the Suid Bokkeveld plateau in the northern part of the species' distribution. -
A Phylogeny of Legumes (Leguminosae) Based on Analysis of the Plastid Matk Gene Resolves Many Well-Supported Subclades Within the Family1
American Journal of Botany 91(11): 1846±1862. 2004. A PHYLOGENY OF LEGUMES (LEGUMINOSAE) BASED ON ANALYSIS OF THE PLASTID MATK GENE RESOLVES MANY WELL-SUPPORTED SUBCLADES WITHIN THE FAMILY1 MARTIN F. W OJCIECHOWSKI,2,5 MATT LAVIN,3 AND MICHAEL J. SANDERSON4 2School of Life Sciences, Arizona State University, Tempe, Arizona 85287-4501 USA; 3Department of Plant Sciences, Montana State University, Bozeman, Montana 59717 USA; and 4Section of Evolution and Ecology, University of California, Davis, California 95616 USA Phylogenetic analysis of 330 plastid matK gene sequences, representing 235 genera from 37 of 39 tribes, and four outgroup taxa from eurosids I supports many well-resolved subclades within the Leguminosae. These results are generally consistent with those derived from other plastid sequence data (rbcL and trnL), but show greater resolution and clade support overall. In particular, the monophyly of subfamily Papilionoideae and at least seven major subclades are well-supported by bootstrap and Bayesian credibility values. These subclades are informally recognized as the Cladrastis clade, genistoid sensu lato, dalbergioid sensu lato, mirbelioid, millettioid, and robinioid clades, and the inverted-repeat-lacking clade (IRLC). The genistoid clade is expanded to include genera such as Poecilanthe, Cyclolobium, Bowdichia, and Diplotropis and thus contains the vast majority of papilionoids known to produce quinolizidine alkaloids. The dalbergioid clade is expanded to include the tribe Amorpheae. The mirbelioids include the tribes Bossiaeeae and Mirbelieae, with Hypocalypteae as its sister group. The millettioids comprise two major subclades that roughly correspond to the tribes Millettieae and Phaseoleae and represent the only major papilionoid clade marked by a macromorphological apomorphy, pseu- doracemose in¯orescences. -
