Foraging Modes of Carnivorous Plants Aaron M
Israel Journal of Ecology & Evolution, 2020 http://dx.doi.org/10.1163/22244662-20191066 Foraging modes of carnivorous plants Aaron M. Ellison* Harvard Forest, Harvard University, 324 North Main Street, Petersham, Massachusetts, 01366, USA Abstract Carnivorous plants are pure sit-and-wait predators: they remain rooted to a single location and depend on the abundance and movement of their prey to obtain nutrients required for growth and reproduction. Yet carnivorous plants exhibit phenotypically plastic responses to prey availability that parallel those of non-carnivorous plants to changes in light levels or soil-nutrient concentrations. The latter have been considered to be foraging behaviors, but the former have not. Here, I review aspects of foraging theory that can be profitably applied to carnivorous plants considered as sit-and-wait predators. A discussion of different strategies by which carnivorous plants attract, capture, kill, and digest prey, and subsequently acquire nutrients from them suggests that optimal foraging theory can be applied to carnivorous plants as easily as it has been applied to animals. Carnivorous plants can vary their production, placement, and types of traps; switch between capturing nutrients from leaf-derived traps and roots; temporarily activate traps in response to external cues; or cease trap production altogether. Future research on foraging strategies by carnivorous plants will yield new insights into the physiology and ecology of what Darwin called “the most wonderful plants in the world”. At the same time, inclusion of carnivorous plants into models of animal foraging behavior could lead to the development of a more general and taxonomically inclusive foraging theory. -

Corydalis Incisa (Fumariaceae) in Bronx and Westchester Counties, New York
Atha, D, J.A. Schuler, and S. Lumban Tobing. 2014. Corydalis incisa (Fumariaceae) in Bronx and Westchester counties, New York. Phytoneuron 2014-96: 1–6. CORYDALIS INCISA (FUMARIACEAE) IN BRONX AND WESTCHESTER COUNTIES, NEW YORK DANIEL ATHA and JESSICA A. SCHULER The New York Botanical Garden Bronx, New York 10458 [email protected] SARAH LUMBAN TOBING NYC Parks Arsenal North 1234 Fifth Avenue, Room 229 New York, New York 10029 ABSTRACT Spontaneously growing plants of the East Asian Corydalis incisa (Thunb.) Pers. (Fumariaceae) are reported from Westchester Co., New York, for the first time. The species was previously only known from a small area along the Bronx River in Bronx Co., New York. The Westchester County plants documented here represent the second known wild population in North America. This discovery increases the number of Corydalis species in North America from ten to eleven and from four to five in the northeastern USA. It is the only spontaneous, purple- or white- flowered species in the Northeast. Corydalis incisa (Thunb.) Pers growing outside of cultivation in North America were first discovered on the floodplain of the Bronx River, near the Burke Avenue Bridge in Bronx Park, New York, by Michael Sundue during the 2005 Bronx River BioBlitz (Sundue, pers. comm). No voucher specimens were collected. Soon after, Steve Glenn collected the species at the same locality and noted "dozens" of individuals along both banks of the River, reported for the first time as naturalized in North America by Lamont et al. (2011). The population has since persisted and expanded. In 2014, a second population was discovered by the authors and is detailed below. -

The Miniature Genome of a Carnivorous Plant Genlisea Aurea
Leushkin et al. BMC Genomics 2013, 14:476 http://www.biomedcentral.com/1471-2164/14/476 RESEARCH ARTICLE Open Access The miniature genome of a carnivorous plant Genlisea aurea contains a low number of genes and short non-coding sequences Evgeny V Leushkin1,2, Roman A Sutormin1, Elena R Nabieva1, Aleksey A Penin1,2,3, Alexey S Kondrashov1,4 and Maria D Logacheva1,5* Abstract Background: Genlisea aurea (Lentibulariaceae) is a carnivorous plant with unusually small genome size - 63.6 Mb – one of the smallest known among higher plants. Data on the genome sizes and the phylogeny of Genlisea suggest that this is a derived state within the genus. Thus, G. aurea is an excellent model organism for studying evolutionary mechanisms of genome contraction. Results: Here we report sequencing and de novo draft assembly of G. aurea genome. The assembly consists of 10,687 contigs of the total length of 43.4 Mb and includes 17,755 complete and partial protein-coding genes. Its comparison with the genome of Mimulus guttatus, another representative of higher core Lamiales clade, reveals striking differences in gene content and length of non-coding regions. Conclusions: Genome contraction was a complex process, which involved gene loss and reduction of lengths of introns and intergenic regions, but not intron loss. The gene loss is more frequent for the genes that belong to multigenic families indicating that genetic redundancy is an important prerequisite for genome size reduction. Keywords: Genome reduction, Carnivorous plant, Intron, Intergenic region Background evolutionary and functional points of view. In a model In spite of the similarity of basic cellular processes in eu- plant species, Arabidopsis thaliana, number of protein- karyotes, their genome sizes are extraordinarily variable. -

Carnivorous plants have been fascinating researchers with their unique characters and bioinspired applications. These include medicinal trait of some carnivorous plants with potentials for pharmaceutical industry. Methods. This review will cover recent progress based on current studies on digestive enzymes secreted by different genera of carnivorous plants: Drosera (sundews), Dionaea (Venus flytrap), Nepenthes (tropical pitcher plants), Sarracenia (North American pitcher plants), Cephalotus (Australian pitcher plants), Genlisea (corkscrew plants), and Utricularia (bladderworts). Results. Since the discovery of secreted protease nepenthesin in Nepenthes pitcher, digestive enzymes from carnivorous plants have been the focus of many studies. Recent genomics approaches have accelerated digestive enzyme discovery. Furthermore, the advancement in recombinant technology and protein purification helped in the identification and characterisation of enzymes in carnivorous plants. Discussion. These different aspects will be described and discussed in this review with focus on the role of secreted plant proteases and their potential industrial applications. -
Major Lineages Within Apiaceae Subfamily Apioideae: a Comparison of Chloroplast Restriction Site and Dna Sequence Data1
American Journal of Botany 86(7): 1014±1026. 1999. MAJOR LINEAGES WITHIN APIACEAE SUBFAMILY APIOIDEAE: A COMPARISON OF CHLOROPLAST RESTRICTION SITE AND DNA SEQUENCE DATA1 GREGORY M. PLUNKETT2 AND STEPHEN R. DOWNIE Department of Plant Biology, University of Illinois, Urbana, Illinois 61801 Traditional sources of taxonomic characters in the large and taxonomically complex subfamily Apioideae (Apiaceae) have been confounding and no classi®cation system of the subfamily has been widely accepted. A restriction site analysis of the chloroplast genome from 78 representatives of Apioideae and related groups provided a data matrix of 990 variable characters (750 of which were potentially parsimony-informative). A comparison of these data to that of three recent DNA sequencing studies of Apioideae (based on ITS, rpoCl intron, and matK sequences) shows that the restriction site analysis provides 2.6± 3.6 times more variable characters for a comparable group of taxa. Moreover, levels of divergence appear to be well suited to studies at the subfamilial and tribal levels of Apiaceae. Cladistic and phenetic analyses of the restriction site data yielded trees that are visually congruent to those derived from the other recent molecular studies. On the basis of these comparisons, six lineages and one paraphyletic grade are provisionally recognized as informal groups. These groups can serve as the starting point for future, more intensive studies of the subfamily. Key words: Apiaceae; Apioideae; chloroplast genome; restriction site analysis; Umbelliferae. Apioideae are the largest and best-known subfamily of tem, and biochemical characters exhibit similarly con- Apiaceae (5 Umbelliferae) and include many familiar ed- founding parallelisms (e.g., Bell, 1971; Harborne, 1971; ible plants (e.g., carrot, parsnips, parsley, celery, fennel, Nielsen, 1971). -

IMPACTS OF LAUREL WILT DISEASE ON NATIVE PERSEA OF THE SOUTHEASTERN UNITED STATES A Dissertation Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Forest Resources by Timothy M. Shearman May 2016 Accepted by: Dr. G. Geoff Wang, Committee Chair Dr. Saara J. DeWalt Dr. Donald L. Hagan Dr. Julia L. Kerrigan Dr. William C. Bridges ABSTRACT Laurel Wilt Disease (LWD) has caused severe mortality in native Persea species of the southeastern United States since it was first detected in 2003. This study was designed to document the range-wide population impacts to LWD, as well as the patterns of mortality and regeneration in Persea ecosystems. I used Forest Inventory and Analysis (FIA) data from the U.S. Forest Service to estimate Persea borbonia (red bay) populations from 2003 to 2011 to see if any decline could be observed since the introduction of LWD causal agents. -
Japanese Hedge Parsley
v. August 9, 2010 Invasive Plants of Wisconsin Hedge-parsleys (Torilis sp.) Authors: Brendon Panke and Mark Renz1 Herbaceous biennials that establish as rosettes with parsley-like leaves. Plants flower in the 2nd year. Flowering stems are spreading, grooved, notably jointed, and covered in hair. Mature plants are typically 2-4’ tall. Legal Classification in WI: Japanese hedge-parsley Torilis japonica – Prohibited/Restricted Spreading hedge-parsley Torilis arvensis - Prohibited Leaves: Stem leaves are pinnately compound, alternate, fern-like, triangular, slightly hairy, and 2-5” long. Leaflets are pinnately divided and clasp the stem. Rosette leaves are similar to stem leaves. Flowers: Midsummer to late summer. White flowers found in small, loose, flat-topped umbels. Japanese hedge-parsley has two or more small bracts at the base of each umbel. Spreading hedge-parsley lacks bracts at the base of each umbel. Fruits & seeds: Each flower produces a pair of bristle-covered fruit that can attach to fur or clothing. Fruit are initially rosy or white-green, but become brown as they mature. Roots: Taproot. Similar species: Wild carrot (Daucus carota) is not as hairy and has larger, flatter, and denser umbels. Caraway (Carum carvi) is shorter, has dark, oblong seeds and leaves that are more finely divided than the hedge-parsleys. Sweet cicely (Osmorhiza) has leaves that are not as fern-like. Wild chervil (Anthriscus sylvestris) flowers in spring. The bristle-covered seed of the hedge-parsleys is a key characteristic to distinguish these two hedge-parsleys from other similar species. Ecological threat: Invades forest edges, fields, fencerows, roadsides, and disturbed areas.
