Nuclear activity of sperm cells during Hyacinthus orientalis L. in vitro pollen tube growth
In this study, the transcriptional state and distribution of RNA polymerase II, pre-mRNA splicing machinery elements, and rRNA transcripts were investigated in the sperm cells of Hyacinthus orientalis L. during in vitro pollen tube growth. During the second pollen mitosis, no nascent transcripts were observed in the area of the dividing generative cell, whereas the splicing factors were present...
متن کاملsnRNP: Rich Nuclear Bodies in Hyacinthus orientalis L. Microspores and Developing Pollen Cells
The aim of the present work was the characterization of nuclear bodies in the microspore and developing pollen cells of Hyacinthus orientalis L.. The combination of Ag-NOR, immunofluorescence and immunogold techniques was used in this study. The obtained results showed the presence of highly agyrophylic extranucleolar bodies in microspore and developing pollen cells, which were finally identifi...
متن کاملIn vitro measurement of pollen tube growth inhibition.
A method for estimating inhibition of pollen tube growth was developed. Pollen is placed in straight lines on an agar surface where it responds uniformly and predictably to aqueous solutions of germination-inhibiting substances located in wells at the ends of the lines. A scale of ratings, roughly corresponding to serial, doubled concentrations of inhibiting substances, was devised. Water-solub...
متن کاملResponse of in vitro pollen germination and pollen tube growth of groundnut ( Arachis hypogaea L.) genotypes to temperature
Air temperatures of greater than 35 ∞ C are frequently encountered in groundnut-growing regions, especially in the semi-arid tropics. Such extreme temperatures are likely to increase in frequency under future predicted climates. High air temperatures result in failure of peg and pod set due to lower pollen viability. The response of pollen germination and pollen tube growth to temperature was q...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
