Abstract
Summary
Plants of Family Aizoaceae are group of dicot plants called ice plants. In Egypt
there are ten species belong to six genera. In this study, we studied nine species
only namely: Mesembryanthemum nodiflorum, Mesembryanthemum
crystallinum, Mesembryanthemum forskahlii, Aizoon canariense, Aizoon
hispanicum, Sesuvium sesuvioides, Trianthema portulacastrum, Trianthema
crystalline, and Zaleya pentandra. These species are collected from the in the
different phytogeographical regions of Egypt, Cairo Herbarium (CAI) and
Damietta Herbarium. The present distribution of the studied species is shown
on drawn maps. Morhological characters of the nine species are compared and
statistically analysed for plant leaves and flower characters
The pollen grains and seeds were acetolized for light microscope (LM) and
scanning electron microscopy (SEM).
Also, Seed protein was analyzed through slab type SDS-PAGE using 11%
polyacrylamide gel of some species of family Aizoaceae for assessment of
taxonomic value.
Herbarium voucher specimens are kept at the Department of Botany, Faculty
of Science Damietta University, Egypt.
Results of this study indicate previously undescribed sets of relationships
within Family Aizoceae in Egypt based on types of pollen. The pollen type is
94
euripalynous. On the basis of the structure of the exine, four types were
recognized: Scabrate, Spinulose and tubiliferous- punctate, punctate-striate and
sparcely-punctate.
The banding pattern of protein peptides in M. crystallinum, M. nodiflorum, M.
forskalli, S. sesvoides and A. canariensis showed 16 protein subunits and out of
these 15 were polymorphic. Variability in intensity was observed in some
bands that indicated the quantity of protein peptides cumulating at a particular
molecular weight.
Cluster analysis based on SDS-PAGE profiles revealed the similarity between
the plants, which indicated that the highest similarity was found between M.
crystallinum and A. canariensis at 97.14% similarity level, also high similarity
was present between M. nodiflorum and S. sesvoides at 96.92% similarity
level. The minimum similarity was found between M. forskahlii and both of M.
nodiflorum and S. sesvoides at 94.36% similarity level.
