Full of Beans: a Study on the Alignment of Two Flowering Plants Classification Systems
Full of beans: a study on the alignment of two flowering plants classification systems Yi-Yun Cheng and Bertram Ludäscher School of Information Sciences, University of Illinois at Urbana-Champaign, USA {yiyunyc2,ludaesch}@illinois.edu Abstract. Advancements in technologies such as DNA analysis have given rise to new ways in organizing organisms in biodiversity classification systems. In this paper, we examine the feasibility of aligning two classification systems for flowering plants using a logic-based, Region Connection Calculus (RCC-5) ap- proach. The older “Cronquist system” (1981) classifies plants using their mor- phological features, while the more recent Angiosperm Phylogeny Group IV (APG IV) (2016) system classifies based on many new methods including ge- nome-level analysis. In our approach, we align pairwise concepts X and Y from two taxonomies using five basic set relations: congruence (X=Y), inclusion (X>Y), inverse inclusion (X<Y), overlap (X><Y), and disjointness (X!Y). With some of the RCC-5 relationships among the Fabaceae family (beans family) and the Sapindaceae family (maple family) uncertain, we anticipate that the merging of the two classification systems will lead to numerous merged solutions, so- called possible worlds. Our research demonstrates how logic-based alignment with ambiguities can lead to multiple merged solutions, which would not have been feasible when aligning taxonomies, classifications, or other knowledge or- ganization systems (KOS) manually. We believe that this work can introduce a novel approach for aligning KOS, where merged possible worlds can serve as a minimum viable product for engaging domain experts in the loop. Keywords: taxonomy alignment, KOS alignment, interoperability 1 Introduction With the advent of large-scale technologies and datasets, it has become increasingly difficult to organize information using a stable unitary classification scheme over time. -

CRONQUIST's SYSTEM of CLASSIFICATION
CRONQUIST’s SYSTEM OF CLASSIFICATION Contents • Introduction •Basis of Classification •Class Magnoliopsida •Class Liliopsida •Merits •De-Mertis •Principles of Classification Arthur Lyman John Cronquist (1919 -1992) was a United States botanist and a specialist on Compositae. He is considered one of the most influential botanists of the 20th century, largely due to his formulation of the Cronquist system OF Classification BASIS OF CLASSIFICATION This system of classification is an elaboration of Bessey’s system of classification and a refinement over Takhtajan’s system (1964), which is based on morphological, anatomical, embryological, palynological, serological, cytological, chemical as well as ultra structural evidences. According to Cronquist’s system of classification, the angiosperms have been divided into two Classes The Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in his texts An Integrated System of Classification of Flowering Plants (1981) and The Evolution and Classification of Flowering Plants (1968; 2nd edition, 1988). • Cronquist's system places flowering plants into two broad classes, Magnoliopsida (dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses. • The scheme is still widely used, in either the original form or in adapted versions, but some botanists are adopting the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG III. • The system as laid out in An Integrated System of Classification of Flowering Plants (1981) counts 321 families and 64 orders in class Magnoliopsida and 19 orders and 65 families in class Liliopsida • Class Magnoliopsida 1. Subclass Magnoliidae (mostly basal dicots)(8 Orders, 39 families) 2. -

Phylogenetic Origins of Parasitic Plants Daniel L. Nickrent Chapter 3, pp. 29-56 in: J. A. López-Sáez, P. Catalán and L. Sáez [eds.], Parasitic Plants of the Iberian Peninsula and Balearic Islands This text first written in English (as appears here) was translated into Spanish and appeared in the book whose Spanish citation is: Nickrent, D. L. 2002. Orígenes filogenéticos de las plantas parásitas. Capitulo 3, pp. 29-56 In J. A. López-Sáez, P. Catalán and L. Sáez [eds.], Plantas Parásitas de la Península Ibérica e Islas Baleares. Mundi-Prensa Libros, S. A., Madrid. Throughout its history, the field of plant systematics has undergone changes in response to the advent of new philosophical ideas, types of data, and methods of analysis. It is no exaggeration to say that the past decade has witnessed a virtual revolution in phylogenetic investigation, owing mainly to the application of molecular methodologies and advancements in data analysis techniques. These powerful approaches have provided a source of data, independent of morphology, that can be used to address long-standing questions in angiosperm evolution. These new methods have been applied to systematic and phylogenetic questions among parasitic plants (Nickrent et al. 1998), but have often raised as many new questions as they have solved, in part due to the amazingly complex nature of the genetic systems present in these organisms. The goal of this chapter is to provide a general synopsis of the current state of understanding of parasitic plant phylogeny. To place in context results concerning the parasites, it is necessary to first examine general features of angiosperm phylogeny. -

Those protein molecules, e.g., legumins, which are subject to less influence of selection processes, have proven to be most valuable as diagnostic characters in phylogenetic studies. Three systematic inves tigations conducted using comparative serological legumin analyses are discussed as contributions aiding botanists' understanding of a natural system of classification. Key words: serology, taxonomy, legumin, dicotyledons. INTRODUCTION Molecular data have proven to be valuable for the reconstruction of the natural system that represents the phylogenetic relationships of organisms including the dicotyledonous spermatophyta, for which fossil data are often fragmentary. In addition to regulatory mutations, point mutations, which are translated into amino acid exchanges within the proteins, are especially important in molecular evo lution. Over extended evolutionary periods, the rate ofamino acid exchange within a protein is believed to be more or less constant and the sequence dissimilarity proportional to the time of divergence between two taxa. -

DICKISON Department ofBiology, University of North Carolina Chapel Hill, North Carolina 27599 ABSTRACf The value of vegetative anatomy in phylogenetic analysis is documented. Examples of the use of vegetative anatomy at different taxonomic levels show the continuing role of the anatomical method in building a more natural system of classification of the dicotyledons. The importance of correlating wood and leaf anatomical features with ecological and floristic preferences of taxa is emphasized. Caution is required in basing phylogenetic interpretations upon similarities and differences in xylem structure. The transition from scalariform to simple perforation plates is the only aspect of vessel element evolution that is not potentially reversible and all phylogenetic analyses must reflect this important principle. Some groups outside the Magnoliidae (Annoniflorae) possess very primitive xylems and can be used as evidence to support a pattern ofmultiple early radiations ofthe dicotyledons, as well as the increased awareness of a lack of clear subclass definition. The application of anatomical characters in cladistic analysis is reviewed, and the need to utilize strictly homologous features, to provide accurate scoring of character states, and to give proper interpretations to character state transformations is emphasized. -
