Rye B Chromosomes Influence the Dynamics of Histone H3 Methylation during Microgametogenesis
Cytogenetic and Genome Research, 2014We have studied the trimethylation dynamics of lysines 4 and 27 of histone H3 in rye with and without B chromosomes (Bs) in root tip mitosis, meiosis, and pollen grain mitosis by immunostaining. In root meristems, H3K4me3 immunolabeling was homogeneous along the chromosome arms of the normal complement (As), with the exception of the pericentromeric ...

Chromosoma, 1953
1. The technique for making autoradiographs with stripping film is described in detail. Methods for administering P32 to plants and for preparation of tissues for autoradiographs are given. 2. Two different methods, enzyme digestion and acid hydrolysis, which were used for separating RNA, DNA, and phosphoprotein in tissue sections, were ...

SYNOPSIS. The fine‐structural aspects of development of microgamonts of Eimeria magna were studied in kidney cell cultures and in experimentally infected rabbits. Spheroidal masses of gamont‐like cytoplasm containing ribosomes, polyribosomes, and amylopectin granules were found within the parasitophorous vacuole; these bodies were apparently pinched ...

[Microsporogenesis y microgametogenesis de annatto (Bixa orellana L.)].
Acta cientifica venezolana, 2003A series of buds of increasing maturity were individually sampled in order to examine cytological events of annatto (Bixa orellana L.), genotype Portuguesa. They were fixed in Carnoy II at 12:30 am, time of the highest rate of meiotic division. Three stain solutions were attempted.

Microgamonts and macrogamonts of Eimeria truncata were observed in renal epithelial cells of collecting tubules and ducts and occasionally in macrophages of experimentally infected lesser snow geese (Anser c. caerulescens) beginning 8.5 days post inoculation. Intraparasitophorous vesicles in parasitophorous vacuoles of both types of gamonts appeared to
