Molecular Differentiation and Phylogenetic Relationship of the Genus Punica (Punicaceae) with Other Taxa of the Order Myrtales
Rheedea Vol. 26(1) 37–51 2016 ISSN: 0971 - 2313 Molecular differentiation and phylogenetic relationship of the genus Punica (Punicaceae) with other taxa of the order Myrtales D. Narzary1, S.A.

(P. granatum L. and P. protopunica Balf.f.), and twelve closely related taxa of the order Myrtales based on sequence of the Internal Transcribed Spacer (ITS) and the 5.8S coding region of the nuclear ribosomal DNA. All the accessions of the Punica grouped into a distinct clade with strong support in Bayesian, Maximum Likelihood and Maximum Parsimony analyses. Trapaceae showed the most distant relationship with other members of Lythraceae s.l. Phylogenetic tree exclusively generated for 42 representative taxa of the family Lythraceae s.l., revealed similar clustering pattern of Trapaceae and Punicaceae in UPGMA and Bayesian trees. All analyses strongly supported the monophyly of the family Lythraceae s.l., nevertheless, the sister relation with family Onagraceae is weakly supported. The analyses of the ITS sequences of Punica in relation to the other taxa of the family Lythraceae s.l., revealed that the genus Punica is distinct under the family Lythraceae, however this could be further substantiated with comparative sequencing of other phylogenetically informative regions of chloroplast and nuclear DNA. -

We use morphology and DNA sequences from the rbcL gene, the trnL-F re- gion, and psaA-ycf3 intergenic spacer of the chloroplast and the internal transcribed spacer region of the nu- cleus to explore relationships for up to 27 genera of the Lythraceae sensu stricto and the monogeneric families Duabangaceae, Punicaceae, Sonneratiaceae, and Trapaceae. Maximum parsimony, maximum likelihood, and Bayesian likelihood approaches are employed. Morphology alone provided little phylogenetic resolution. Results from individual gene regions were relatively well resolved and largely congruent, whereas basal rela- tionships were poorly supported. A combined gene analysis of 20 genera produced one fully resolved max- imum parsimony tree that corresponded closely to the maximum likelihood and Bayesian trees in which a monophyletic Lythraceae includes Duabanga, Punica, Sonneratia, and Trapa as derived genera within the family. Decodon is sister to the rest of the family in the maximum parsimony and Bayesian trees, followed by Lythrum and Peplis at the node above and then by the rest of the family, which diverges into two superclades. -
THE EVALUATION of Cuphea Pulchra and Cuphea Schumannii AS POTENTIAL NEW ORNAMENTAL CROPS for INTRODUCTION INTO the FLORICULTURE INDUSTRY
THE EVALUATION OF Cuphea pulchra AND Cuphea schumannii AS POTENTIAL NEW ORNAMENTAL CROPS FOR INTRODUCTION INTO THE FLORICULTURE INDUSTRY DISSERTATION Presented in Partial Fulfillment of the Requirements for The Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Jennifer Hrach Leopold, B.S. ***** The Ohio State University 2004 Dissertation Committee: Approved by Dr. James Metzger, Advisor Dr. Margaret McMahon ________________________ Advisor Dr. David Gardner Horticulture and Crop Science Dr. Michael Boehm Graduate Program ABSTRACT Two species, Cuphea pulchra and Cuphea schumannii, native to Brazil and Mexico respectively, were evaluated for their potential as new ornamental crops. Both species are characteristic of the genus as suffrutescent sub-shrubs bearing intensely colored orange, ribbed flowers. No information exists regarding the horticultural qualities of either species. The objectives of the current research were to evaluate the species for ornamental qualities and begin developing information pertinent to commercial production. Propagation by vegetative cutting was the most efficacious method of propagating both species. Use of a 0.1% indol-3-butyric acid rooting hormone promoted increased root development on C. schumannii stem cuttings but had no significant effect on C. pulchra cuttings. Initial greenhouse observations and the results of three consecutive years of outdoor trials demonstrated that C. schumannii possess relatively little horticultural potential, due to an indeterminate growth habit, high susceptibility to green peach aphid infestation and development of leaf intumescence under greenhouse conditions. Conversely, C. pulchra holds much promise as an annual, landscape/garden bedding plant with its compact growth habit, sustained heavy production of attractive flowers, and resistance to greenhouse and outdoor insect pests. -

Genetics and Cytogenetics of Cuphea Viscosissima X Cuphea Lanceolata Hybrid Populations
AN ABSTRACT OF THE THESIS OF Tina L. Brandtfor the degree ofMaster of ScienceinCrop Science presented onJuly 15, 1991. Title: Genetics and Cytogenetics of Cuphea Viscosissima X Cuphea Lanceolata Hybrid Populations Redacted for Privacy Abstract approved: Steven J. Knalip" Cuphea is currently under domestication as a potential oilseed crop. Interest in Cuphea is based on the fact that many of its species have seedsrich in medium-chain fatty acids. Species of interest include Cuphea viscosissima (2n= 2x= 12) and Cuphea lanceolata (2n= 2x= 12). Interspecific hybrid populations were produced between C. viscosissima and two C. lanceolata forms, f. silenoides and f. typica. The C. viscosissima x C. lanceolata f. typica population did not produce seed after selfing and pollen stained with 12KI was 100% non-viable. The C. viscosissima x C. lanceolata f. silenoides population produced seed after selfing and the pollen was 75% viable. Pairing configurations at diakinesis and chromosome segregation at anaphase I differed between the two interspecific hybrid populations. The mean frequency of chiasma formation (c) was 0.53 for the C. viscosissimax C. lanceolata f. silenoides population and 0.26 for the C. viscosissima x C. lanceolata f. typica population. The genome affinity index (GM) estimate was 0.98 and thearm affinity estimate (AAI) was 0.65 for the C. viscosissimax C. lanceolata f. silenoides population. The GM estimate was 0.52 and the AAI estimatewas 0.34 for the C. viscosissima x C. lanceolata f. typica population. Fatty acid phenotypes of C. viscosissima x C. lanceolata f. silenoides F2 and backcross individuals were analyzed using gas chromatography. -

Cuphea Plant Nitrate Content and Seed Yield Response to Nitrogen
Reprinted from: Issues in new crops and new uses. 2007. J. Janick and A. Whipkey (eds.). ASHS Press, Alexandria, VA. Cuphea Plant Nitrate Content and Seed Yield Response to Nitrogen Fertilizer Marisol Berti, Burton Johnson, Russ Gesch, and Frank Forcella Cuphea (Cuphea viscosissima Jacq. × C. lanceolata W.T. Aiton, PSR23, Lythraceae), is a new oilseed crop being developed in the Upper Midwest. Cuphea species are summer-annual plants native to North, Cen- tral, and South America. The only species native to the USA is C. viscosissima Jacq. (Knapp 1993). Cuphea seed oil is rich in medium-chain fatty acids (MCFA) such as caprylic (C8:0), capric (C10:0), lauric (C12:0), and myristic (C14:0) (Graham and Kleiman 1992). Cuphea lanceolata has high capric acid (70%) (Kleiman 1990), and C. llavea has about the highest level of capric acid (92 %) (Phippen et al. 2006). Cuphea viscosissima × C. lanceolata line PSR23 seed has 270 to 300 g kg-1 of oil. The typical fatty acid distribution includes 69.9% capric, 2.9% lauric, 4.4% myristic, 5.9% palmitic, 9.4% oleic, and 4.8% linoleic acids. Cuphea oil has an iodine value of 19.7, and a high oxidative stability of 157 hr at 110°C comparable to that of coconut oil (Cocos nucifera L., Arecaceae). The content of free fatty acids (4%–4.25%) and chlorophyll (200–260 mg kg-1) in the crude oil are high (Evangelista and Manthey 2006). Medium-chain fatty acids can be used to replace saturated fatty acids and plasticizers in chewing gum. Cuphea oil also works well as a flow carrier and solvent in the candy industry, and as a defoaming agent and booster in soap and detergent manufacturing (Ag Innovation News 2003). -
Exodermal Function and Suberin Chemistry
Exodermal Function and Suberin Chemistry by Christopher John Meyer A thesis presented to the University of Waterloo in fulfilment of the thesis requirement for the degree of Doctor of Philosophy in Biology Waterloo, Ontario, Canada, 2010 © Christopher John Meyer 2010 Author's Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract The thesis work concerns the multiseriate exodermis (MEX), an outermost cortical layer (two or more cell layers thick) characterized by Casparian bands and suberin lamellae. Diverse aspects of Iris germanica's MEX were examined including its maturation under differing growth conditions, and how this maturation affected water and solute permeability. Also, suberin metabolite profiles for the maturing MEX of I. germanica and the maturing uniseriate exodermis of Allium cepa were established. This multidisciplinary approach resulted in a comprehensive understanding of how anatomical and biochemical changes to the exodermis affect water and solute permeability of the MEX. Most previous studies of exodermal development have involved species with a uniseriate exodermis. To extend this work, the MEX in I. germanica roots was investigated. The outermost exodermal layer matured first with normal Casparian bands and suberin lamellae. But as subsequent layers matured, the Casparian band extended into the tangential and anticlinal walls of their cells. This atypical Casparian band was continuous around the root circumference. MEX maturation was influenced by the roots' growth medium. Plants were grown in soil or hydroponics (with and without a humid air gap), and their roots were sectioned and stained with various dyes to detect Casparian bands and suberin lamellae.
