Anatomy of ovary and ovule in dandelions (Taraxacum, Asteraceae)
TLDR
A comparative study of the ovary and especially the ovule anatomy in the diploid dandelion T. linearisquameum and the triploid T. gentile revealed no essential differences, and the role of the thick-walled integumentary layers in the dandelions ovule is discussed.
Formation of germ-line cysts with a central cytoplasmic core is accompanied by specific orientation of mitotic spindles and partitioning of existing intercellular bridges
TLDR
Analysis of the formation and architecture of cystocytes clusters during early stages of spermatogenesis and oogenesis in a few species belonging to clitellate (oligochaetous) annelids indicates that the appearance of germ cells connected via a central cytophore is accompanied by a specific orientation of the mitotic spindles during cystocyte divisions.
Anti-Cancer Activity of Derivatives of 1,3,4-Oxadiazole
TLDR
In most publications, the most active derivatives of 1,3,4-oxadiazole exceeded the effect of reference drugs, so they may become the main new anti-cancer drugs in the future.
Ovary cord structure and oogenesis in Hirudo medicinalis and Haemopis sanguisuga (Clitellata, Annelida): remarks on different ovaries organization in Hirudinea
TLDR
The successive stages of oogenesis of H. medicinalis in detail is described: fully developed oocytes arrested in meiotic metaphase I float freely in the ovary lumen.
Oogenesis in the leech Glossiphonia heteroclita (Annelida, Hirudinea, Glossiphonidae). I. Ovary structure and previtellogenic growth of oocytes
TLDR
Oogenesis in G. heteroclita is synchronous with all oocytes in the ovary in the same stage of oogenesis, and the morphology of the follicle cells surrounding the nurse cells and penetrating the ovaries does not change, whereas those enveloping the growing oocytes become more voluminous.
Structure of the germinal vesicle during oogenesis in leech Glossiphonia heteroclita (Annelida, Hirudinea, Rhynchobdellida)
TLDR
The amplification of rDNA genes, the occurrence of extrachromosomal DNA bodies, as well as the presence of multiple nucleoli and accessory nuclei are described for the first time in the phylum Annelida.
Integument cell differentiation in dandelions (Taraxacum, Asteraceae, Lactuceae) with special attention paid to plasmodesmata
TLDR
Ulastructural analysis of the periendothelial zone mucilage cells was performed on examples of the ovule tissues of several sexual and apomictic Taraxacum species to determine what happens with plasmodesmata when mucilage is secreted into the periplasmic space in plant cells.
