Embryogenesis in Angiosperms: Development of the Suspensor.
The zygote in flowering plants usually divides transversely to form a terminal cell, which gives rise to the embryo proper, and a vacuolated basal cell, which often divides rapidly to form a structure known as the suspensor. Angiosperm suspensors vary widely in size and morphology from a single cell to a massive column of several hundred cells (Maheshwari, 1950; Wardlaw, 1955; Lersten, 1983). I...
متن کاملSparticarpin: A Pterocarpan Phytoalexin from Spartium junceum
Although pterocarpan phytoalexins commonly ac cumulate in the fungus-inoculated tissues of papilionate legumes, only three compounds of this type possess oxygenation at C-2 [1, 2]. They are 2,3,9-trimethoxypterocarpan (1), 2,9-dimethoxy-3-hydroxypterocarpan (2-methoxymedicarpin, 2) and 2,3,9-trimethoxy-4-hydroxypterocarpan (3) all of which co occur with pisatin in the Fusarium solani f. sp. p...
متن کاملExperimental control of Spanish broom (Spartium junceum) invading natural grasslands
A group of legumes generically known as brooms are among the most successful shrubs invading grasslands in South America and other regions. These species share a set of biological features that enhance their invasiveness, such as abundant and long-lasting seed banks, aggressive root systems and rapid growth, combined with their ability for re-sprouting after cutting or burning and for avoiding ...
متن کاملEMBRYOGENESIS AND RHIZOGENESIS IN MATURE ZYGOTIC EMBRYOS OF OLIVE (OLEA EUROPAEA L.) CULTIVARS MISSION AND KRONEIKI
Organogenesis and neoformant plantlet production were studied by culturing the different parts of mature embryo including radicle and proximal and distal parts of cotyledon of Mission and Kroneiki cultivars. Different parts of embryos were cultures in OMc medium containing growth regulators, such as indole butyric acid (IBA) and 2-isopentenyl adenine (2-ip) or IBA and naphthalene acetic acid (N...
