Impact of Chromosomal Rearrangements on the Interpretation of Lupin Karyotype Evolution
Plant genome evolution can be very complex and challenging to describe, even within a
genus. Mechanisms that underlie genome variation are complex and can include whole-genome
duplications, gene duplication and/or loss, and, importantly, multiple chromosomal
rearrangements. Lupins (Lupinus) diverged from other legumes approximately 60 mya. In contrast
to New World lupins, Old World lupins show high variability not only for chromosome numbers
(2n = 32–52), but also for the basic chromosome number (x = 5–9, 13) and genome size. The
evolutionary basis that underlies the karyotype evolution in lupins remains unknown, as it has so
far been impossible to identify individual chromosomes. To shed light on chromosome changes and
evolution, we used comparative chromosome mapping among 11 Old World lupins, with Lupinus
angustifolius as the reference species. We applied set of L. angustifolius-derived bacterial artificial
chromosome clones for fluorescence in situ hybridization. We demonstrate that chromosome
variations in the species analyzed might have arisen from multiple changes in chromosome
structure and number. We hypothesize about lupin karyotype evolution through polyploidy and
subsequent aneuploidy. Additionally, we have established a cytogenomic map of L. angustifolius
along with chromosome markers that can be used for related species to further improve
comparative studies of crops and wild lupins
Aligning a New Reference Genetic Map of Lupinus angustifolius with the Genome Sequence of the Model Legume, Lotus japonicus
We have developed a dense reference genetic map of Lupinus angustifolius (2n = 40) based on a set of 106 publicly available recombinant inbred lines derived from a cross between domesticated and wild parental lines. The map comprised 1090 loci in 20 linkage groups and three small clusters, drawing together data from several previous mapping publications plus almost 200 new markers, of which 63 were gene-based markers. A total of 171 mainly gene-based, sequence-tagged site loci served as bridging points for comparing the Lu. angustifolius genome with the genome sequence of the model legume, Lotus japonicus via BLASTn homology searching. Comparative analysis indicated that the genomes of Lu. angustifolius and Lo. japonicus are highly diverged structurally but with significant regions of conserved synteny including the region of the Lu. angustifolius genome containing the pod-shatter resistance gene, lentus. We discuss the potential of synteny analysis for identifying candidate genes for domestication traits in Lu. angustifolius and in improving our understanding of Fabaceae genome evolution

APPENDIX I: LIST OF COMMON ACRONYM
Wykorzystanie zmiennosci markerow izoenzymatycznych do charakterystyki genotypow odmian grochu [Pisum sativum L.]
Analizę polimorfizmu izoenzymów zastosowano do charakterystyki zmienności genetycznej i identyfikacji odmian hodowlanych grochu. Wybrane linie z banku genów Pisum reprezentowały wszystkie aktualnie zarejestrowane odmiany. Przebadano zmienność 10 systemów enzymatycznych w 21 odmianach grochu biało kwitnącego i 12 barwnie kwitnącego. Polimorfizm wewnątrzodmianowy przynajmniej jednego locus obserwowano w 9 odmianach. Wykryty zakres zmienności izoenzymatycznej 11 loci pozwolił na rozróżnienie wszystkich odmian grochu biało kwitnącego, natomiast identyfikacja wszystkich odmian grochu barwnie kwitnącego wymagała obserwacji polimorfizmu 14 loci. Wyznaczone współczynniki podobieństwa pomiędzy odmianami wykorzystano do dyskusji nad ich pokrewieństwem i zakresem zmienności puli genowej stosowanej w hodowli twórczej. Uzyskane wyniki wzbogaciły charakterystykę genotypów odmian stanowiących część materiałów kolekcyjnych. Tego rodzaju informacje mogą być wykorzystane w pracach hodowlanych do identyfikacji i kontroli czystości odmian grochów podczas produkcji i dystrybucji materiałów nasiennych.Isozyme polymorphism analysis was used for genetic variability characterization and identification of pea cultivars. Lines chosen from the Gene Bank of Pisum represented actually registered Polish cultivars. Variability of 10 enzyme systems was examined among 21 white flowering and 12 colour flowering pea cultivars. Intravarietal polymorphism at least of one locus was observed in 9 cultivars. Detected range of isozyme variability of 11 loci enabled to distinguish all white flowering pea cultivars but the identification of all colour flowering pea cultivars required 14 loci polymorphism observation. Calculated coefficients of similarity among the cultivars were used for discussion on their relationship and on the variability range of gene pool applied in creative breeding. Obtained results enriched the cultivars characteristics of cultivar genotypes which are a part of collected materials. This kind of information can be used in breeding projects for identification and pea cultivar purity control during production and distribution of seed materials
Linkages in Pisum L. VII. Locus for the sterile gene calf [cabbage leaf]
Genetical analyses were conducted to find linkages and the locus of the gene calf on the Pisum chromosome map. The recessive, pleiotropic gene calf (enlarged and undulated leaflets, stipules, flowers and pods, plant sterile), artificially induced (the initial line-Large Podded G-20, the mutagene-DES and NMU) was described by Sharma in 1975. An identical mutant gene at the same locus was isolated in our research (the initial line - cv. Pegro, the mutagene - fast neutrons). Two lines were included in the Pisum gene bank - the type line for the gene calf - Wt 15873 and the representative line - Wt 16024. In linkage studies the representative line was crossed with tester lines bearing gene markers. Analyses of dihybrid segregation in F₂ generations revealed linkages of the gene calf with chromosome 2 markers. Two isozymic markers helped to reveal the calf locus on chromosome 2 with the following gene order: Orp - Calf - K - Pgm-p - Fum. This is in agreement with the current Pisum linkage map
A dense reference map of the Lupinus Angustifolius L. Genome: A foundation for building lupin genome research
A genetic map provides a foundation on which genomic research can be built, linking together otherwise disconnected studies and forming the basis on which to build physical and cytogenetic maps and conduct whole genome sequencing. As part of a wide collaborative effort, we developed a dense genetic map of the narrow-leafed lupin (Lupinus angustifolius L.) comprising 1073 molecular markers, 6 domestication trait loci and an Anthracnose resistance locus distributed across 20 major linkage groups. This map will be used to investigate the extent of genome conservation between narrow-leafed lupin and the model legume species, Medicago truncatula and Lotus japonicus. We discuss the potential applications of this reference map in lupin genetic and genomic research
Zmiennosc loci izoenzymatycznych w kolekcji podstawowej rodzaju Pisum
Zgromadzone w krajowej kolekcji Pisum w Wiatrowie zasoby obejmują dzikie populacje, odmiany uprawne i miejscowe, wyselekcjonowane mutanty spontaniczne i indukowane oraz linie pochodzące z krzyżowań w programach hodowlanych i badawczych. Utworzono z nich kolekcję podstawową rodzaju Pisum (266 obiektów), reprezentującą dotychczas opisaną zmienność monogeniczną w genotypach typowych dla alleli, liniach testowych z genami - markerami poszczególnych chromosomów oraz z nowymi genami.
Dla zwiększenia przydatności kolekcji podstawowej Pisum zgromadzonej w Wiatrowie scharakteryzowano zakres zmienności loci izoenzymatycznych. Analizowano polimorfizm 18 loci izoenzymatycznych metodą rozdziału elektroforetycznego na żelu skrobiowym. Wszystkie badane loci enzymatyczne wykazały obecność 2-4 allozymów. Niektóre z wykrytych allozymów występowały bardzo rzadko, najczęściej w populacjach należących do dzikich gatunków Pisum. Zakres obserwowanej zmienności izoenzymatycznej w poszczególnych grupach obiektów posłużył do obliczenia częstości alleli i oceny polimorfizmu każdej z grup oraz porównania zmienności pomiędzy grupami. Uzyskane wyniki wykorzystano do dyskusji na temat wykorzystania markerów izoenzymatycznych do charakterystyki genotypu obiektów kolekcyjnych.The Pisum national collection at Wiatrowo covers wild populations, culti- vars and land races, selected spontaneous and induced mutants, as well as cross derivatives from breeding and research programs. There has been constituted the core collection of Pisum genus (266 accesions), representing hitherto described monogenic variability in typical genotypes for alleles, tester lines with marker genes for particular chromosomes, and with new genes.
To increase the usefulness of Pisum core collection gathered at Wiatrowo, the range of isozyme loci variability was characterized. The polymorphism of 18 isozyme loci was analyzed using electrophoretic separation on starch gel. All tested loci showed the presence of 2-4 allozymes. Some of them occurred very rarely, usually in populations belonging to the wild species of Pisum. The range of observed isozyme variability in particular groups of accesions was used for statistical calculations of allele frequency and for estimating polymorphism in each group as well as for comparison of variability among groups. The results were used for discussion on utility of isozyme markers for genotype characterization of collection accessions
