Meiotic Crossing-over: Obligation and Interference

Gareth H. Jones, F. Chris H. Franklin

Cell > 2006 > 126 > 2 > 246-248

During meiosis, crossing-over—the exchange of genetic material between maternal and paternal chromosomes—is stringently controlled to restrict the number of crossovers per chromosome pair. In this issue of Cell, Martini et al. (2006) report that the reduction of crossover-initiating events does not result in fewer crossovers. These results have important implications for our understanding of crossover...

Chromosome synapsis in Arabidopsis: analysis of the transverse filament protein ZYP1 reveals novel functions for the synaptonemal complex

Kim Osman, Eugenio Sanchez-Moran, James D. Higgins, Gareth H. Jones, more

Chromosoma > 2006 > 115 > 3 > 212-219

With respect to history, plants have provided an ideal system for cytogenetical analysis of the synaptonemal complex (SC). However, until recently, the identification of the genes that encode the SC in plants has proved elusive. In recent years, Arabidopsis thaliana was developed as a model system for plant meiosis research. As a result, there was substantial progress in the isolation of meiotic genes...

The effect of grafted poly(ethylene glycol) on the electrophoretic properties of phospholipid liposomes and their adsorption to bacterial biofilms

Khalid Ahmed, Patrick W. Muiruri, Gareth H. Jones, Matthew J. Scott, more

Colloids and Surfaces A: Physicochemical and Engineering Aspects > 2001 > 194 > 1-3 > 287 - 296

Liposomes have been prepared from the phospholipids, dimyristoyl, dipalmitoyl and distearoyl phosphatidylcholine (DMPC, DPPC, DSPC, respectively) containing dimethyldioctadecylammonium bromide (DDAB) or phosphatidylinositol (PI) and variable amounts (0-9 mole%) of dipalmitoylphosphatidylethanolamine bonded to poly(ethylene glycol) [PEG] of molecular mass 2000 (DPPE-PEG-2000). The electrophoretic mobilities...

Integrated Cytogenetic Map of Chromosome Arm 4S of A. thaliana: Structural Organization of Heterochromatic Knob and Centromere Region

Paul F. Fransz, Susan Armstrong, J. Hans de Jong, Laurence D. Parnell, more

Cell > 2000 > 100 > 3 > 367-376

We have constructed an integrated cytogenetic map of chromosome arm 4S of Arabidopsis thaliana. The map shows the detailed positions of various multicopy and unique sequences relative to euchromatin and heterochromatin segments. A quantitative analysis of the map positions at subsequent meiotic stages revealed a striking pattern of spatial and temporal variation in chromatin condensation for euchromatin...

A homologue of the yeast HOP1 gene is inactivated in the Arabidopsis meiotic mutant asy1

Anthony P. Caryl, Susan J. Armstrong, Gareth H. Jones, F. Christopher H. Franklin

Chromosoma > 2000 > 109 > 1/2 > 62-71

Abstract. Synapsis of homologous chromosomes is a key event in meiosis as it is essential for normal chromosome segregation and is implicated in the regulation of crossover frequency. We have previously reported the identification and cytological characterisation of a T-DNA-tagged asynaptic mutant of Arabidopsis thaliana. We have demonstrated that this mutant, asy1, is defective in meiosis in both...
