Repetitive DNA in the Architecture, Repatterning, and Diversification of the Genome of Aegilops speltoides Tausch (Poaceae, Triticeae)

open access: yesFrontiers in Plant Science, 2018
The genome’s adaptability to environmental changes, especially during rapid climatic fluctuations, underlies the existence and evolution of species. In the wild, genetic and epigenetic genomic changes are accompanied by significant alterations in the ...

Glycerol-3-phosphate acyltransferase 3 (OsGPAT3) is required for anther development and male fertility in rice [PDF]

open access: yes, 2017
Lipid molecules are key structural components of plant male reproductive organs, such as the anther and pollen. Although advances have been made in the understanding of acyl lipids in plant reproduction, the metabolic pathways of other lipid compounds ...

CHR11, a chromatin-remodeling factor essential for nuclear proliferation during female gametogenesis in Arabidopsis thaliana [PDF]

open access: yes, 2005
Chromatin-remodeling factors regulate the establishment of transcriptional programs during plant development. Although 42 genes encoding members of the SWI2/SNF2 family have been identified in Arabidopsis thaliana, < 10 have been assigned a precise ...

Global transcriptome analysis of two ameiotic1 alleles in maize anthers: defining steps in meiotic entry and progression through prophase I [PDF]

open access: yes, 2011
Background Developmental cues to start meiosis occur late in plants. Ameiotic1 (Am1) encodes a plant-specific nuclear protein (AM1) required for meiotic entry and progression through early prophase I. Pollen mother cells (PMCs) remain mitotic in most am1

Azadirachtin Disrupts Formation of Organised Microtubule Arrays during Microgametogenesis of Plasmodium berghei

open access: yesJournal of Eukaryotic Microbiology, 2002
ABSTRACT. Transmission of malaria parasites from vertebrate blood to the mosquito vector depends critically on the differentiation of the gametocytes into gametes. This occurs in response to environmental stimuli encountered by the parasite in the mosquito bloodmeal.

Plasmodium P-type cyclin CYC3 modulates endomitotic growth during oocyst development in mosquitoes [PDF]

open access: yes, 2015
Cell-cycle progression and cell division in eukaryotes are governed in part by the cyclin family and their regulation of cyclin-dependent kinases (CDKs). Cyclins are very well characterised in model systems such as yeast and human cells, but surprisingly

Molecular characterisation of the of genes encoding putative leucine-rich repeat receptor-like kinases in [PDF]

open access: yes, 2007
Receptor-like kinases are a prominent class of surface receptors that regulate many aspects of the plant life cycle. Despite recent advances the function of most receptor-like kinases remains elusive.
