Downregulation of Barley Regulator of Telomere Elongation Helicase 1 Alters the Distribution of Meiotic Crossovers

Frontiers in Plant Science, 2021
Programmed meiotic DNA double-strand breaks (DSBs), necessary for proper chromosomal segregation and viable gamete formation, are repaired by homologous recombination (HR) as crossovers (COs) or non-crossovers (NCOs). The mechanisms regulating the number

Lorentz Transformation and Light-Like Noncommutative SYM [PDF]

, 2000
We show that combining the spatial noncommutative SYM limit and Lorentz transformation, one can obtain a well-behaved light-like noncommutative SYM limit. The light-like noncommutative SYM is unitary.

The Nigerian Correctional Service (NCoS): Challenges and Opportunities in Deradicalization and Reintegration

Mangabdi
This article examines the role of the Nigerian Correctional Service (NCoS) in deradicalization programs in Nigeria. Its objectives are to analyze the programs and services provided by NCoS, identify the challenges encountered, and evaluate NCoS’s efforts

Non-Commutative Open (p,q)-String Theories

, 2001
In this paper we make an SL(2,Z)-covariant generalisation of the noncommutative theories, NCYM and NCOS on the D3-brane, and NCOS on the D5-brane in type IIB. Usually, the noncommutative theories are obtained by studying perturbative F-string theory, and

Noncommutative Open String Theories and Their Dualities [PDF]

, 2001
The recently found non-critical open string theories is reviewed. These open strings, noncommutative open string theories (NCOS), arise as consistent quantum theories describing the low energy theory of D-branes in a background electric B-field in the ...

Quantifying Cloud-Free Observations from Landsat Missions: Implications for Water Environment Analysis

Journal of Remote Sensing
Since the launch of the Landsat missions, they have been widely employed for monitoring water environments. However, the designed revisiting period of Landsat satellites is 16 days, leading to large uncertainties when tracking long-term changes in water ...

High-throughput 454 resequencing for allele discovery and recombination mapping in Plasmodium falciparum

BMC Genomics, 2011
Background Knowledge of the origins, distribution, and inheritance of variation in the malaria parasite (Plasmodium falciparum) genome is crucial for understanding its evolution; however the 81% (A+T) genome poses challenges to high-throughput sequencing

OM Theory and V-duality [PDF]

, 2001
We show that the (M5, M2, M2$'$, MW) bound state solution of eleven dimensional supergravity recently constructed in hep-th/0009147 is related to the (M5, M2) bound state one by a finite Lorentz boost along a M5-brane direction perpendicular to the M2 ...

Synthesis-dependent strand annealing in meiosis.

PLoS Biology, 2007
Recent studies led to the proposal that meiotic gene conversion can result after transient engagement of the donor chromatid and subsequent DNA synthesis-dependent strand annealing (SDSA).

Characterization of meiotic crossovers and gene conversion by whole-genome sequencing in Saccharomyces cerevisiae

BMC Genomics, 2009
Background Meiotic recombination alters frequency and distribution of genetic variation, impacting genetics and evolution. In the budding yeast, DNA double strand breaks (DSBs) and D loops form either crossovers (COs) or non-crossovers (NCOs), which ...
