GEOGRAPHICAL VARIATION OF AJUGA ORIENTALIS L. TRICHOME, NUTLET AND POLLEN

Volatile oil composition of the aerial parts of Ajuga orientalis L. from Iran.

The volatile oil content and composition of the aerial parts of Ajuga orientalis L. (Lamiaceae) grown in northern parts of Iran have been analyzed by GC/MS. Thirty compounds were identified, representing 97.9% of the total oil. The main compounds were germacrene-D (24.2%), beta-cubebene (18.3%), beta-caryophyllene (16.9%) and alpha-cubebene (5.3%).

snRNP: 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...

Redescription and geographical variation of Monopeltis guentheri Boulenger (Amphisbaenia, Reptilia)

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...

Esterase polymorphisms in relict endemic Liquidambar orientalis Mill. var. orientalis and L. orientalis Mill. var. integriloba Fiori populations in Turkey

In this study, esterase isozyme polymorphisms in Boreal-Tertiary origin relict endemic L. orientalis populations were investigated. Four populations located in the Southern and the Southwestern regions of Turkey were screened. Two of these populations (Fethiye-Günlüklü and Fethiye-İnlice) belong to subspecies L. orientalis Mill.var. orientalis. The other two (Muğla-Köyceğiz and Antalya-Gebiz) b...
