dc.description.abstract | In most angiosperms, the female gametophyte is hidden in the mother tissues and the
pollen tube enters the ovule via a micropylar canal. The mother tissues play an essential role in
the pollen tube guidance. However, in Utricularia, the female gametophyte surpasses the entire
micropylar canal and extends beyond the limit of the integument. The female gametophyte then
invades the placenta and a part of the central cell has direct contact with the ovary chamber. To date,
information about the role of the placenta and integument in pollen tube guidance in Utricularia,
which have extra-ovular female gametophytes, has been lacking. The aim of this study was to
evaluate the role of the placenta, central cell and integument in pollen tube pollen tube guidance in
Utricularia nelumbifolia Gardner and Utricularia humboldtii R.H. Schomb. by studying the production
of arabinogalactan proteins. It was also determined whether the production of the arabinogalactan
proteins is dependent on pollination in Utricularia. In both of the examined species, arabinogalactan
proteins (AGPs) were observed in the placenta (epidermis and nutritive tissue), ovule (integument,
chalaza), and female gametophyte of both pollinated and unpollinated flowers, which means that the
production of AGPs is independent of pollination; however, the production of some AGPs was lower
after fertilization. There were some differences in the production of AGPs between the examined
species. The occurrence of AGPs in the placental epidermis and nutritive tissue suggests that they
function as an obturator. The production of some AGPs in the ovular tissues (nucellus, integument)
was independent of the presence of a mature embryo sac. | pl_PL |
