TL;DR: The fragmentation was substantially suppressed in mre11 spo11-1 double mutants, indicating that Mre11 is required for repair but not for the induction of Spo11-dependent meiotic DNA breaks in Arabidopsis.

TL;DR: The genetic control of sex determination from a number of plant species is reviewed to illustrate the variety of extant mechanisms and species that are now used as models to investigate the molecular biology ofsex determination are emphasized.

TL;DR: Analysis of terminal restriction fragments in different tissues and ontogenetic stages showed that telomere lengths are stabilized precisely and do not change during plant growth and development, suggesting their precise control during plant ontogenesis; however, the telomeres length regulation mechanism could be unbalanced during in vitro dedifferentiation.

TL;DR: The genetic and physical mapping, expression analysis, and molecular evolutionary analysis of a sex-linked gene from S. latifolia, DD44, suggest that chromosomal rearrangements have occurred on the Y chromosome, which may have contributed to the genetic isolation of the Y chromosomes.

TL;DR: The genomic subtraction method representational difference analysis (RDA) was used to identify male-specific restriction fragments in the dioecious plant Silene latifolia, which revealed a Y-linked locus, not previously described, which is responsible for early stamen development.
