Integration of retrotransposons-based markers in a linkage map of barley
A deeper understanding of random markers is important if they are to be employed for a range of
objectives. The sequence specific amplified polymorphism (S-SAP) technique is a powerful genetic analysis
tool which exploits the high copy number of retrotransposon long terminal repeats (LTRs) in the plant
genome. The distribution and inheritance of S-SAP bands in the barley genome was studied using the
Steptoe · Morex (S · M) double haploid (DH) population. Six S-SAP primer combinations generated 98
polymorphic bands, and map positions were assigned to all but one band. Eight putative co-dominant loci
were detected, representing 16 of the mapped markers. Thus at least 81 of the mapped S-SAP loci were
dominant. The markers were distributed along all of the seven chromosomes and a tendency to cluster was
observed. The distribution of S-SAP markers over the barley genome concurred with the knowledge of
the high copy number of retrotransposons in plants. This experiment has demonstrated the potential for the
S-SAP technique to be applied in a range of analyses such as genetic fingerprinting, marker assisted
breeding, biodiversity assessment and phylogenetic analyses

Measurement of the CP violating asymmetry amplitude sin 2beta
We present results on time-dependent CP-violating asymmetries in neutral B
decays to several CP eigenstates. The measurements use a data sample of about
88 million Y(4S) --> B Bbar decays collected between 1999 and 2002 with the
BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We study
events in which one neutral B meson is fully reconstructed in a final state
containing a charmonium meson and the other B meson is determined to be either
a B0 or B0bar from its decay products. The amplitude of the CP-violating
asymmetry, which in the Standard Model is proportional to sin2beta, is derived
from the decay-time distributions in such events. We measure sin2beta = 0.741
+/- 0.067 (stat) +/- 0.034 (syst) and |lambda| = 0.948 +/- 0.051 (stat) +/-
0.030 (syst). The magnitude of lambda is consistent with unity, in agreement
with the Standard Model expectation of no direct CP violation in these modes.Comment: 7 pages, 2 postscript figures, submitted to PR
