BOTANY,Semester 02,MBOTCC 06,Contemporary System of Classification:Armen Takhtajan,D.K.Jha (Lecture Series No
BOTANY,Semester 02,MBOTCC 06,Contemporary system of classification:Armen Takhtajan,D.K.Jha (lecture series no. 06). ARMEN TAKHTAJAN (B.1910) was Head of the Dept. Of Plant Science at Leningrad,Russia.He presented a system of classification of Angiosperms for the first in 1942 and thereafter it’s revised versions in 1954,1966,1969 and finally in 1980 in his book in English entitled Flowering Plants ;Origin and Dispersal.His system is basically inspired by Bassey_Hallier tradition as he also considered evidences from fields like Morphology,Anatomy, Embryology, Cytology,Palynology ,Chemistry etc. According to Takhtajan angiosperms aremonophyletic in origin and have derived from Gymnosperms.Monocots are derived from some primitive dicots. Takhtajans classification is based on some phyletic principles: 1Woody plants are primitive than herbaceous plants. 2.Deciduous woody plants are derived from evergreen plants. 3.Stomata without subsidiary cells are more advanced than stomata with subsidiary cells. 4 .Alternate lead phyllotaxy is more primitive than other types. 5.Parallel venation is advanced. 6.Cymose inflorescence is primitive than racehorse. 7.Polymerous flowers are primitive. 8 Pollen with smooth exine is primitive than sculptured exine. 9. Apocarpous gynoecium is more primitive than syncarpous. 10.Bitegmic ovules are more primitive than unitegmic. 11.Anatropous ovules are more primitive than others. 12.Polygonum type embryosac is most primitive. 13.Porogamic condition is more primitive than mesogamic and chalazogamic. 14. Many seeded follicle fruits are most primitive. 15. Endospermic seeds are primitive.Dicot embryo is primitive than monocot embryo. Brief outline of Takhtajans system Takhtajan has replaced traditional nomenclature of Angiosperm,Dicotyledonae and Monocotyledonae by Magnoliophyta,Magnoliopsida and Liliopsida respectively. -

To date, 1.5 million species of organisms have been recorded, although around 85% of potential species (some 10 million) have not yet been identified. In the case of the Neotropics, although insects are clearly a vital element, there are many families of organisms and regions that are yet to be well researched. -

GENOME EVOLUTION in MONOCOTS a Dissertation
GENOME EVOLUTION IN MONOCOTS A Dissertation Presented to The Faculty of the Graduate School At the University of Missouri In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy By Kate L. Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field. -

WILSON1,2 1Rancho Santa Ana Botanic Garden, 1500 North College Avenue, Claremont, California 91711-3157, USA 2Corresponding author ([email protected]) ABSTRACT Phoradendron, the largest mistletoe genus in the New World, extends from temperate North America to temperate South America. Most species are parasitic on terrestrial hosts, but a few occur only, or primarily, on other species of Phoradendron. We examined relationships among two obligate epiparasites, P. durangense and P. falcatum, and their parasitic hosts. Fruit and seed of both epiparasites were small compared to those of their parasitic hosts. Seed of epiparasites was established on parasitic-host stems, leaves, and inflorescences. Shoots developed from the plumular region or from buds on the holdfast or subjacent tissue. The developing endophytic system initially consisted of multiple separate strands that widened, merged, and often entirely displaced its parasitic host from the cambial cylinder. -
Reconstructing the Basal Angiosperm Phylogeny: Evaluating Information Content of Mitochondrial Genes
55 (4) • November 2006: 837–856 Qiu & al. • Basal angiosperm phylogeny Reconstructing the basal angiosperm phylogeny: evaluating information content of mitochondrial genes Yin-Long Qiu1, Libo Li, Tory A. Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships.
