Some Effects of Photoperiod and Cold Storage on Oviposition of the Cereal Leaf Beetle Oulema Melanopus (Coleptera: Chrysomelidae) [PDF]
An expanded program of research on the cereal leaf beetle, Oulema melanopus (L.), in various north-central states has made it necessary to develop methods of rearing all stages of the beetle for laboratory use. Because the insect survives diapause in the

F-53B interferes with meiosis and damages reproduction in Arabidopsis thaliana
The emerging contaminant chlorinated polyfluoroalkyl ether sulfonic acid (Cl-PFESA, trade name F-53B) damages mitotic cell viability leading to inhibited vegetative development in plants.

AtPV42a and AtPV42b redundantly regulate reproductive development in Arabidopsis thaliana. [PDF]
BACKGROUND: The conserved SNF1/AMPK/SnRK1 complexes are global regulators of metabolic responses in eukaryotes and play a key role in the control of energy balance.

The life cycles of cryptogams [PDF]
Meiosis and karyogamy are recognized as control points in the life cycle of cryptogams. The control of meiosis is evidently complex and in yeast, and by analogy in all cryptogams, involves progressive gene activation.

YAO is a nucleolar WD40-repeat protein critical for embryogenesis and gametogenesis in Arabidopsis [PDF]
Background In flowering plants, gametogenesis generates multicellular male and female gametophytes. In the model system Arabidopsis, the male gametophyte or pollen grain contains two sperm cells and a vegetative cell.

Cell cycle length, cell size, and proliferation rate in hydra stem cells [PDF]
We have analyzed the cell cycle parameters of interstitial cells in Hydra oligactis. Three subpopulations of cells with short, medium, and long cell cycles were identified. Short-cycle cells are stem cells; medium-cycle cells are precursors to nematocyte

Chemical Competition between Microscopic Stages of Macrocystis pyrifera and Five Native Kelp Species: Does Giant Kelp Always Lose? [PDF]
The giant kelp Macrocystis pyrifera is often considered competitively dominant to other kelp species due to its high productivity. However, on the microscopic level, previous studies found that Macrocystis can be inferior to other kelp species through ...

DNA methylation remodeling and the functional implication during male gametogenesis in rice
Background Epigenetic marks are reprogrammed during sexual reproduction. In flowering plants, DNA methylation is only partially remodeled in the gametes and the zygote.
