rDNA mapping, heterochromatin characterization and AT/GC content of Agapanthus africanus (L.) Hoffmanns (Agapanthaceae).
Agapanthus (Agapanthaceae) has 10 species described. However, most taxonomists differ respect to this number because the great phenotypic plasticity of the species. The cytogenetic has been an important tool to aid the plant taxon identification, and to date, all taxa of Agapanthus L'Héritier studied cytologically, presented 2n = 30. Although the species possess large chromosomes, the group is ...
متن کاملAntifungal properties of Agapanthus africanus L. extracts against plant pathogens
Crude extracts of various Agapanthus africanus plant parts were screened in vitro against eight economically important plant pathogenic fungi. Radial mycelial growth was inhibited significantly (Po0.05) in five test organisms, while Pythium ultimum, and to a lesser extent Fusarium oxysporum and Alternaria alternata, showed a degree of tolerance. Subsequently, these crude extracts were tested in...
متن کاملSomatic Embryogenesis and Plant Regeneration from Embryonic Axes and Cotyledons Explants of Tea (Camellia sinenesis L.)
In the present study, 2, 4-dichlorophenoxyacetic acid (2, 4-D) was assessed individually for its effectiveness to induce somatic embryogenesis in tea (Camellia sinenesis L.). Embryonic axes and cotyledons explants were dissected from the seeds. Explants were cultured on Murashige and Skoog (MS) medium containing 0, 1 and 5 mM 2, 4-D alone for embryonic axes and 0, 1 and 5 mM 2, 4-D along with 0...
متن کاملInduction of Callus and Somatic Embryogenesis from Cotyledon Explants of Fagonia indica Burm.
To explore the potential for in vitro rapid regeneration of Fagonia indica Burm., cotyledon explants were obtained from 10-day old aseptically germinated seedlings that cultured on MS medium which supplemented with 1.0-5.0 µM 2,4-D. Callus was initiated from cotyledon explant on MS medium supplemented in all concentrations of 2,4-D investigated. 2,4-D was more effective than IAA and NAA for cal...
متن کاملZygotic embryogenesis versus somatic embryogenesis
This review will summarize molecular and genetic analyses aimed at identifying the mechanisms underlying the sequence of events during plant zygotic embryogenesis. These events are being studied in parallel with the histological and morphological analyses of somatic embryogenesis. The strength and limitations of somatic embryogenesis as a model system will be discussed briefly. The formation of...
