The relationships among the examined samples have been demonstrated as UPGMA and Neighbor joining (NJ) trees that agree with the taxonomy and ecogeographic distribution of the studied species. In both trees the 27 samples have been divided in two major groups; one small group comprised of the New World species and a large group comprised of the Old World species. The North American lupines are clearly delimited as separate identities with high levels of dissimilarity between them particularly in the UPGMA tree. In the NJ tree high levels of dissimilarity are observed between L. sativus and L. sylvestris and a cluster comprised of L. mutabilis, L. succulentus, L. elegans and L. hartwegii. The relationships among the Old World species, with few exceptions, correlate well with their morphology and intercrossing data. The morphologically diverse and genetically well-differentiated smooth-seeded species were separated as one group from the morphologically homogeneous and genetically less differentiated rough-seeded lupines. In the smooth seeded lupines, the separation of L. albus (2n=50) and L. angustifolius (2n=40) is congruent with their sectional delimitation, However, L. micranthus, (sect. Micranthi) and L. luteus and L. hispanicus (sect. Lutei) all have 2n=52. The rough seeded species are differentiated into two clusters; one includes the three samples of L. consentinii (2n=32) and the other comprises the two samples of L. pilosus (2n=42) and atlanticus (2n=38).https://taec.journals.ekb.eg/article_12278_6d0c6419dedbb3efa89009b8432beb9e.pdfCairo University Herbarium (CAI)Taeckholmia1110-741326120061201Seed protein analyses as a support to the transfer of Trigonella cylindracea Desv. and T. polyceratia (L.) Trautv. to genus Medicago L.17331227910.21608/taec.2006.12279ENReamMarzoukBotany Dept., Faculty of Science, Alexandria University, Alexandria, Egypt.Journal Article20060327The present study has been planned to investigate the extent to which seed proteins and peptide mapping may be used as evidences to discuss the position of T. cylindracea Desv. and T. Polyceratia (L.) Trautv. To achieve this objective two outgroups (reference species): Trigonella foenum-graecum L. and Medicago sativa L., represent the type species for each genus were used. Each species was considered as an operational taxonomic unit (OTU) for the purpose of classification and ordination. The bands from 1D-SDS-PAGE or the spots from 2D-peptide mapping were scored as 0 representing absence and 1 representing presence, and employed in the analysis by using NTSYS-pc computer and PAST programs. Cluster analysis and PCA using the protein data from the two different techniques demonstrated that the similarity between T. polyceratia and M. sativa is more than that to T. foenum-graecum. The present paper accepts the transfer of T. polyceratia to Medicago and recommends further studies for T. cylindracea.https://taec.journals.ekb.eg/article_12279_68d0b948057eb14de300158209e23817.pdfCairo University Herbarium (CAI)Taeckholmia1110-741326120061201Systematic implications of seed coat morphology in Campanulaceae Juss.35621228010.21608/taec.2006.12280ENZeinabElwanDepartment of Botany, Faculty of Science, Ain Shams University, Abassia Cairo, EgyptAbdel-MonaimAboel-AttaDepartment of Biological Sciences and Geology, Faculty of Education, Ain Shams University, Roxy - Cairo, Egypt.MohamedLoutfyDepartment of Biological Sciences and Geology, Faculty of Education, Ain Shams University, Roxy - Cairo, Egypt.EhabKamelDepartment of Biological Sciences and Geology, Faculty of Education, Ain Shams University, Roxy - Cairo, EgyptJournal Article20060712I n the present study the seed coat micromorphology of 51 accessions of the Campanulaceae s. l. were investigated via SEM, the selected OTU's include accessions representing 11 genera and 35 species of the subfamilies: Campanuloideae and Lobelioideae. This study is an attempt to investigate variation between the species and the taxonomic relationships between them. Variations in seed coat micro-sculpture supported the monophyly of the family, favored the retention of Lobelia in the Campanulaceae, showed a relatively isolated nature of Edraianthus serbicus and suggested that the genus Campanula as is currently constituted may be polyphyletic and needs further studies. The study also recorded a relatively high degree of polymorphism within the seed shape and seed coats of the different accessions of the same species, thus suggesting more future studies for their re-evaluation.https://taec.journals.ekb.eg/article_12280_5c6540c2d98fc5c1f293ece1230f78aa.pdfCairo University Herbarium (CAI)Taeckholmia1110-741326120061201Reproductive ecology of Panicum turgidum Forssk.63881228210.21608/taec.2006.12282ENKamalBatanounyBotany Department, Faculty of Science, Cairo University, Cairo, EgyptKamalZayedBotany Department, Faculty of Science, Cairo University, Cairo, EgyptHananKabielBotany Department, Faculty of Science, Cairo University, Cairo, EgyptJournal Article20060930Panicum turgidum Forssk. is a drought-resistant C4 plant which exhibits high growth rates in late spring and summer months. Seed germination under different constant and alternating temperatures and the best time for propagation of this species were studied. The responses of the plant to different water regimes were also estimated. The present study revealed that the seed germination was successful under relatively high temperature. Propagation by transplants was favoured in months with moderate temperatures, so as not to cause excessive loss of water and drying of transplants. Cultivation of Panicum turgidum under different water treatments showed that its growth was greatly influenced by the amount of available water. The increase of growth was reflected mostly on the biomass, tillering capacity and the seed output.https://taec.journals.ekb.eg/article_12282_ec446aa4553ad611b557577415e8b025.pdfCairo University Herbarium (CAI)Taeckholmia1110-741326120061231The use of seed proteins as revealed by SDS-PAGE in the taxonomy of some Astragalus species (Fabaceae)891031228310.21608/taec.2006.12283ENSalwaBadrBotany Department, Faculty of Science, Tanta University, Tanta, EgyptJournal Article20061005Total seed proteins of 20 Astragalus L. species belonging to 16<br />sections were electrophoretically analyzed using SDS-PAGE<br />technique. Multivariate analysis (cluster and principal coordinate<br />analysis) of the electrophoretic data showed heterogeneity<br />between some taxa. This heterogeneity was discussed on the light<br />of the controversy over the taxonomic position of Astragalus L.<br />species. The relationships among the examined taxa have been<br />demonstrated as cluster tree using SYSTAT-pc software. This<br />tree illustrated that the studied taxa were separated into two major<br />groups, the New World and the Old World species. The New World<br />group include the species Astragalus wootoni, A. allochrous, A. palmeri,<br />A. layneae, A. lentiginosus, A. nothoxys, A. minthorniae and A.<br />nuttallianu. However, Astragalus coccineus, A. pectinatus and A.<br />didymocarpus that considered from the New World, but separated in the<br />Old World group. Astragalus layneae separated from the rest taxa in the<br />New World group. This species was located in a separate section<br />layneani. The Old World group divided into three subgroups and<br />discussed on the light of earlier classification.https://taec.journals.ekb.eg/article_12283_fbaad6df4a3f55cc624216f588aecf3b.pdfCairo University Herbarium (CAI)Taeckholmia1110-741326120061231Genetic diversity as revealed by AFLP fingerprinting and systematic relationships of species in Sesbania (Fabaceae)1051201228510.21608/taec.2006.12285ENHanaaEl-ShazlyDepartment of Biological and Geological Sciences, Faculty of Education,
Ain Shams University, Roxy, Cairo, EgyptJournal Article20061020Genetic diversity has been revealed, using AFLP finger printing, in 37<br />accessions representing 21 species of Sesbania. The AFLP data has been<br />analyzed and distance trees, illustrating the relationships within and<br />among species, have been constructed using UPGMA and neighbor<br />joining (NJ) methods as implemented in the NTSYS-pc software. Both<br />trees illustrated polymorphism between accessions of the same species,<br />from different origins, but illustrated that intraspecific accessions have<br />closer genetic affinity to each other than to other species. The NJ and<br />UPGMA distance trees clearly delimited the species of the two subgenera<br />Agati and Daubentonia as two separate groups from those in subgenus<br />Sesbania. The AFLP data revealed considerable polymorphism among<br />species of subgenus Sesbania that is not correlated with karyotype<br />resemblances of species in this subgenus and their ability to cross. Based<br />on AFLP data this subgenus may be regarded the center from which<br />species in the other two subgenera have been derived. In the NJ tree S.<br />quadrata and S. rostrata are distinguished from two large groups, but in<br />the UPGMA tree S. quadrata is grouped with S. bispinosa and S.<br />cannabina, whereas S. rostrata is grouped with S. exaltata in one of the<br />NJ groups. The delimitation of species based on the analyses of AFLP<br />data is discussed in the light of their systematic delimitation.https://taec.journals.ekb.eg/article_12285_b71afe4efc54d18c08ff31a7953fbded.pdfCairo University Herbarium (CAI)Taeckholmia1110-741326120061231Rare and interesting moss records from Egypt1211291228710.21608/taec.2006.12287ENHanaa MostafaShabbaraFaculty of Science, Ain Shams University, Cairo, EgyptJournal Article20061015Four new rare moss taxa are recorded from Egypt; Archidium<br />alternifolium (Dicks. ex Hedw.)

More than 70% of the entire flora has been classified<br />as either “very rare” (42.2%) or “rare” (28%). Only 3% of the flora are<br />introduced species. Land use appears to have a critical effect on plant<br />abundance; intensely populated areas in the Nile region have more<br />common or very common species rather than rare and very rare. Annuals<br />and perennials account for approximately equal fractions of the flora<br />(47% each). The spectrum of life-forms is dominated by herbs (75%),<br />Shrubs and shrublets are well-represented while trees are poorly<br />represented (1.3%) in the flora of Egypt.<br />Floristic diversity was high in the Mediterranean coastal regions and low<br />in all desert areas. Frequency of abundance classes and life history traits<br />varied according to the major habitats (weedy, sandy, saline, freshwater,<br />rocky and gravely). Implications of these results for conservation policy<br />are discussed.https://taec.journals.ekb.eg/article_12290_b0fe607c82b5dbd50c72fd44e3dfe19b.pdf
