It is the second largest genus of the Vicia , tribe Fabeae, after , in the region (and in Iran with 23 species). In the regional Flora (Flora of Turkey Flora Iranica and flora of Lathyrus Pisum Iran), the genus has been divided into 9-10 sections. Here we analyzed the phylogeny of and its relationship with matK based on plastid gene sequences. Objectives: The present study utilized several approaches including maximum parsimony, Bayesian and maximum likelihood Lathyrus methods to evaluate the monophyly and relationship within the genus , both at the sectional level and species level, mainly based on the taxa growing in Iran. Materials and Methods: Lathyrus Pisum Vicia A total of 52 accessions, representing 38 species of , three species of and four species of Lens matK and as out-groups, were analyzed for reconstructing the phylogenetic relationship using chloroplast gene sequences. Maximum parsimony, Bayesian and maximum likelihood methods were used to construct phylogenetic trees. Results: Pisum Lathyrus Lathyrus Clymenum The present study indicated that was nested among species. Two members of the section, Lathyrus ochrus L. Clymenum Pisum, ( and ) with formed a weakly supported clade as sister to the larger polytomy comprising the Lathyrus Lathyrus Lathyrostylis Lathyrus Clymenum remainder of the species. Several sections of including , and were monophyletic. Lathyrus roseus Orobon Lathyrus (of the monotypic section ) were nested among the members of section . The newly taxon described L. alamutensis Lathyrostylis Linearicarpus Orobus Pratensis species , endemic to Iran, were nested among other species of . , and were Pratensis Aphaca L. Pratensis not monophyletic sections. and the monotypic section were the closest taxa. In our analysis, formed a Aphaca sister group relationship with the clade, not its own section. Conclusions: matK Lathyrus Shimodaira-Hasegawa (SH) test of the data set showed that all of the analyzed species formed their Pisum Lathyrus own clade and was sister to them. Furthermore, when we removed the two above-mentioned species, the analysis Pisum, Lathyrus retrieved as a well-supported clade being sister to the calde. Keywords: Fabaceae; Lathyrus; Tribe Fabeae 1.

ABSTRACT Lathyrus species are well placed to meet the increasing global demand for food and animal feed, at the time of climate change. Conservation and sustainable use of the genetic resources of Lathyrus is of significant importance to allow the regain of interest in Lathyrus species in world. A comprehensive global database of Lathyrus species originating from the Mediterranean Basin, Caucasus, Central and West Asia Regions is developed using accessions in major genebanks and information from eight herbaria in Europe. This Global Lathyrus database was used to conduct gap analysis to guide future collecting missions and in situ conservation efforts for 37 priority species. The results showed the highest concentration of Lathyrus priority species in the countries of the Fertile Crescent, France, Italy and Greece.

  • Lathlati FABA FINAL
    Lathyrus latifolius L. Common Names: Perennial Pea (1), Everlasting Pea (2), Broad-leaved Everlasting Pea (3). Etymology: Lathyrus comes from Lathyros, a leguminous plant of Ancient Greece classified by Theophrastus and believed to be an aphrodisiac. “The name is often said to be composed of the prefix, la, very, and thuros, passionate.” (1). Latifolius means broad-leaved (4). Botanical synonyms: Lathyrus latifolius L. var. splendens Groenl. & Rumper (5) FAMILY: Fabaceae (the pea family) Quick Notable Features: ¬ Winged stem and petioles ¬ Leaves with only 2 leaflets ¬ Branched leaf-tip tendril ¬ Pink papilionaceous corolla (butterfly- like) Plant Height: Stem height usually reaching 2 m (7). Subspecies/varieties recognized: Lathyrus latifolius f. albiflorus Moldenke L. latifolius f. lanceolatus Freyn (5, 6): Most Likely Confused with: Other species in the genus Lathyrus, but most closely resembles L. sylvestris (2). May also possibly be confused with species of the genera Vicia and Pisum. Habitat Preference: A non-native species that has been naturalized along roadsides and in waste areas (7). Geographic Distribution in Michigan: L. latifolius is scattered throughout Michigan, in both the Upper and Lower Peninsula. In the Upper Peninsula it is found in Baraga, Gogebic, Houghton, Keweenaw, Mackinac, Marquette, Ontonagon, and Schoolcraft counties. In the Lower Peninsula it is found in the following counties: Alpena, Antrim, Benzie, Berrien, Calhoun, Cass, Charlevoix, Cheboygan, Clinton, Emmet, Genesee, Hillsdale, Isabella, Kalamazoo, Kalkaska, Kent, Leelanau, Lenawee, Livingston, Monroe, Montmorency, Newaygo, Oakland, Oceana, Ostego, Saginaw, Sanilac, Van Buren, Washtenaw, and Wayne (2, 5). At least one quarter of the county records are newly recorded since 1985: 29 county records were present in 1985 and there are 38 county- level records as of 2014.

Naci ONUS1 Mehmet BİLGEN2 1Akdeniz University Faculty of Agriculture Department of Horticulture, 07059 Antalya, Turkey 2Akdeniz University Faculty of Agriculture Department of Field Crops, 07059 Antalya, Turkey Correspondence addressed E-mail: [email protected] Abstract In this study using the chloroplast matK DNA sequence, a chloroplast-encoded locus that has been shown to be much more variable than many other genes, from one hundred and forty two plant species belong to the families of 26 plants we conducted a study to contribute to the understanding of major evolutionary relationships among the studied plant orders, families genus and species (clades) and discussed the utilization of matK for molecular phylogeny. Determined genetic relationship between the species or genera is very valuable for genetic improvement studies. The chloroplast matK gene sequences ranging from 730 to 1545 nucleotides were downloaded from the GenBank database. These DNA sequences were aligned using Clustal W program. We employed the maximum parsimony method for phylogenetic reconstruction using PAUP* program. Trees resulting from the parsimony analyses were similar to those generated earlier using single or multiple gene analyses, but our analyses resulted in strict consensus tree providing much better resolution of relationships among major clades. We found that gymnosperms (Pinus thunbergii, Pinus attenuata and Ginko biloba) were different from the monocotyledons and dicotyledons. We showed that Cynodon dactylon, Panicum capilare, Zea mays and Saccharum officiarum (all are in the C4 metabolism) were improved from a common ancestors while the other cereals Triticum Avena, Hordeum, Oryza and Phalaris were evolved from another or similar ancestors.

  • Spring Plants
    This article is part of a weekly series published in the Batavia Daily News by Jan Beglinger, Agriculture Outreach Coordinator for CCE of Genesee County. Master Gardener Corner: Spring Charmers Originally Published: April 14, 2015 There is nothing better after any winter than to see that first bloom in the garden. Most are familiar with the traditional spring bloomers - crocus, daffodils and tulips, but there are other plants that herald spring is on the way. Add any of these plants to your landscape for a brilliant splash of spring color. Cornus mas, commonly called Cornelian cherry dogwood, is valued for its very early spring blooms which open earlier than forsythia. Yellow flowers on short stalks bloom before the leaves emerge in dense, showy, rounded clusters. This is a medium to large deciduous shrub or small tree that is native to central and southern Europe into western Asia. It typically grows 15 to 25 feet tall with a spread of 12 to 20 feet wide. Scaly, exfoliating bark develops on mature trunks for winter interest. Zones 4 to 8. Witch hazels (Hamamelis spp.) are large shrubs that have wispy, twisted, ribbon-like delicate blooms that stand up to early spring weather. Depending on the species or cultivar, the flows come in shades of red, yellow and orange; some are even fragrant. Bloom time depends heavily on the weather. In a mild winter they could bloom in February! Witch hazels perform best when planted in a moist but well-drained, loamy, acidic soil. Zones 5 to 8. Cyclamen coum is a tuberous herbaceous perennial, growing just 2 to 3 inches tall.

Diesen Phasen werden 1577 Blütenpflanzen Mittel- europas, vorwiegend solche mit Hauptverbreitung im planaren bis montanen Bereich, zugeordnet, aufge­ teilt auf 12 grobe G esellschaftsgruppen (А-M). Hieraus ergeben sich zwei Artenlisten mit phänologischen bzw. symphänologischen Angaben in gesellschaftsspezifischer Gliederung und alphabetischer Reihenfol­ ge (Anhang 1-2). Für die Gesellschaftsgruppen werden symphänologische Gruppenspektren erstellt und kommentiert. Abstract: Phenological and symphenological species groups of flowering plants of central Europe By means of phenological characteristics (time from beginning to full development of flowering) of forest plant species, 9 phenological groups have been established which characterize phenophases 1-9 of the vegetation period. Afterwards, 1577 plant species of central Europe were classified into these phenolo­ gical groups, especially those growing in lower to montane areas (i.e. excluding alpine plants). These species belong to 12 groups of plant communities (А-M ; some with subgroups a-b). On this basis two species lists are prepared, one with symphenological groups related to the community groups A- M (appendix 1) and one in alphabetic sequence (appendix 2). Symphenological group spectra were estab­ lished and are discussed for the community groups.
