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.

  • Production of Disomic Wheat-Barley Chromosome Addition Lines Using Hordeum Bulbosum Crosses
    Genet. Res., Gamb. (1981), 37, pp. 215-219 215 Printed in Great Britain SHORT PAPER Production of disomic wheat-barley chromosome addition lines using Hordeum bulbosum crosses BY A. K. M. R. ISLAM AND K. W. SHEPHERD Department of Agronomy, Waite Agricultural Research Institute, The University of Adelaide, Glen Osmond, South Australia, 5064 (Received 1 September 1980) SUMMARY The possibility of using Hordeum bulbosum Crosses to facilitate production of disomic wheat-barley addition lines from monosomic additions was investigated. Aneuhaploids with 22 chromosomes were obtained in the expected gametic frequencies after crossing monosomic, disomio and monotelo-disomic addition lines, involving four different barley chromosomes, as the female parent with tetraploid H. bulbosum. Thus the added barley chromosomes were not eliminated when preferential elimination of the bulbosum chromo- somes took place in the hybrid embryos. Disomic addition lines were obtained after treating the aneuhaploids with colchicine. This method could have wider application in the production of other wheat-alien chromosome disomic addition lines, especially where the transmission frequency of the alien chromosome through the pollen is very low, but its use will depend on the wheat parent being crossable with H. bulbosum and the alien chromosome being retained during the elimination of bulbosum chromosomes. 1. INTRODUCTION After O'Mara (1940) described a systematic procedure for adding individual pairs of rye chromosomes to wheat, many other workers have used a similar approach to add chromosomes of several other alien species to wheat. These addition lines have had many uses including assigning genes in the alien species to particular chromosomes, determining the genetic similarity (homoeology) between alien chromosomes and particular wheat chromosomes, and also for transferring desirable characters such as disease resistance from the alien species to wheat.

  • Having Gametic Chromosome Number Are Called Haploids
    Session-10 Classification of Haploids Haploids: Plants (or the sporophyte) having gametic chromosome number are called haploids. Classification of Haploids: According to their cytological features, haploids have been classified into different types (Fig. 17.1), a brief description of which is given below. I. Euhaploid: The chromosome number of such a haploid is an exact multiple of one of the basic numbers of the group. Euhaploids are of two types: i) Mono-haploid or monoploid: It arises from a diploid species (2x) and possesses the gametic chromosome number of the species; it is designated as “x”. (ii) Polyhaploid: Haploid individuals arising from a polyploid species (4x (autotetraploid), 6x (autohexaploid), etc.,) are called polyhaploids; they may be di-haploids (with 2x), tri- haploids (3x) and so on. Based on their auto- or allo-ploid condition, polyhaploids have been divided into two groups: (a) Auto-polyhaploid : Autopolyploid species give rise to auto-polyhaploids. For example, Autotetraploid (Ax = AAAA)———-> Auto-di-haploid (2n = AA) Auto-hexaploid (6x = AAAAAA)———–> Auto-tri-haploid (3x = AAA) (b) Allopolyhaploid : Such individuals arise from allopolyploid species. For example, Allotetraploid {Ax = AABB)———-> Allodihaploid (2x = AB) Allohexaploid (6x = AABBDD)———–> Allotrihaploid (3x = ABD) II. Aneuhaploid: The chromosome number of such a haploid is not an exact multiple of the basic number of the group. Aneuhaploids have been classified into five types: (i) Disomic haploids (n + 1): Such haploids have one chromosome in disomic condition, i.e., there is one extra chromosome belonging to the genome involved. (ii) Addition haploids (n + few alien): The extra chromosome(s) in the haploid is an alien chromosome.

  • Barley (Hordeum Vulgare L.) Is the Fourth Most Important Cereal Crop in the Word and in Many Regions of the Word in Which It Is the Most Important Crop
    PLANTBREEDINGANDSEEDSCIENCE Volume 56 2007 JerzyH.Czembor1,RichardPickering2 1PlantBreedingandGeneticsDepartment,PlantBreedingandAcclimatizationInstitute, Radzikow,05-870Blonie,Poland, 2NewZealandInstituteforCropandFoodResearchLtd, PrivateBag4704,Christchurch,NewZealand POWDERYMILDEWRESISTANCEINRECOMBINATLINES ORIGINATINGFROMCROSSESBETWEEN HORDEUM VULGARE AND HORDEUMBULBOSUM ABSTRACT Six recombinant lines obtained from crosses and backcrosses of barley cultivars (backcrossing parents) and accessions of H. bulbosum were tested with 18 differential isolates of Blumeria graminis f.sp. hordei. Based on screening tests it was concluded that resistance to powdery mildew is present in all tested recombinant lines. Outstanding resistance to powdery mildew was identified in line 81882/83/3/2/9. This line showed re- sistance reaction 2 for inoculation with all isolates used. In 2 lines (81882/83/3/2/9 and 4176/n/3/2/6) it was not possible to postulate presence of known resistance genes for powdery mildew resistance. However based on fact that these lines comes from cross of cultivar Vada which expresses very limited resistance to powdery mildew with accession S1 (H. bulbosum) it may be concluded that expressed resistance comes from H. bulbosum. Moreover we can postulate presence in line 81882/83/3/2/9 of gene or genes which determine re- sistance reaction 2 for powdery mildew. In 4 other lines originating from cross of cultivar Emir and H. bulbosum the presence of unknown genes together with Mla12 was postulated. Most probably gene Mla12 postulated to be present in these lines originate from barley cultivar Emir and unknown gene or genes postu- lated originate from H. bulbosum parents. The possibilities to use hybrid lines with identified resistance to powdery mildew originating from H. bulbosum, especially line 81882/83/3/2/9 resistant to infection with all isolates used, in barley breeding programmes were discussed.

Vada x H. bulbosum L. crosses is shown to be linked with the gene controlling susceptibility to DDT and is thus located on barley chromosome 7. A recombination fraction of 0112 0•032 was obtained. Certain similarities are described between this incompatibility and others known to exist in the Triticeae. 1. INTRODUCTION Doubled haploid production of barley has been successfully achieved by pollinating Hordeum vulgare L. with H. bulbosum L. (Kasha and Kao, 1970). Following fertilisation the H. bulbosum chromosomes are usually eliminated resulting in a haploid H. vulgareembryowhich is rescued to an artificial nutrient medium. Subsequently haploid plants are treated with an aqueous solution of colchicine to double the chromosome number and restore fertility. One problem sometimes associated with the technique was observed early in the development of the programme at the Welsh Plant Breeding Station. This was a partial incompatibility between H. vulgare cv. Vada and H. bulbosum leading to reduced seed setting because of pollen tube inhibition in the stylodium and upper ovary wall transmitting tract (Pickering, 1981). The reaction is known to be controlled by a single dominant gene in Vada (Pickering and Hayes, 1976). Since then several other cultivars, some unrelated to Vada, have been reported as possessing a similar incompatibility with H.

  • Substrate Preferences of Ruderal Plants in Colonizing Stone Monuments of the Pasargadae World Heritage Site, Iran
    sustainability Article Substrate Preferences of Ruderal Plants in Colonizing Stone Monuments of the Pasargadae World Heritage Site, Iran Zohreh Hosseini * , Giulio Zangari, Marta Carboni and Giulia Caneva Department of Science, University of Roma Tre, 00146 Rome, Italy; [email protected] (G.Z.); [email protected] (M.C.); [email protected] (G.C.) * Correspondence: [email protected]; Tel.: +39-06-5733-6374 Abstract: Plant colonization on archaeological structures is limited by the substrate conditions of stone surfaces. Despite its relevance for ecological studies and the management plans of archaeologi- cal sites, the knowledge on monuments substrate (e.g., stones, microhabitats, microsites), which could be suitable sites for plant establishment, is an underestimated topic. Here, we aim to identify the sub- strate preference of plants in colonizing stone surfaces as a first step in evaluating the biodeterioration risk. We selected the Pasargadae World Heritage Site (WHS) for its variety of different conditions, and we assessed the substrate preference of 142 ruderal plants occurring on nine monuments, two types of stones, and eight microsites. Our data indicated that stone typology and microsite conditions affected species composition, diversity, and richness. The porosity of the different limestone and the progressive weathering phenomena resulted as relevant factors in plant colonization. Significantly, microsites as a junction of two stone blocks (M1a) and big fractures covered by soil (M3) hosted the most favorable conditions, which needed periodic monitoring during the maintenance activities of the site. Evaluating the substrate preference of ruderal plants can contribute to the identification of the high-risk areas for plant colonization, which need to be considered in the management plans of Citation: Hosseini, Z.; Zangari, G.; archaeological sites.

Karyotype and seed protein profile analysis of diploid and tetraploid Hordeum bulbosum L. — Phyton (Austria) 25 (1): 31—38, with 3 figures. — English with German summary. Two native greek diploid and tetraploid cytotypes of Hordeum bulbosum L. (Poaceae) morphologically similar, were collected from two separate localities and studied by combining karyotype analysis and seed protein profiles obtained by isoelectric focusing. The karyotype of the diploid cyto- type (2n = 14) was fully established and it was found a symmetrical one. In the tetraploid cytotype, six chromosome pairs, recognized as markers, were found to present in double presence three corresponding pairs of the diploid complement. The protein profiles received from both cytotypes of H. bul- bosum were found to possess the same 22 pi bands, only some bands are different in intensity.
