The Rp1 region of maize was originally characterized as a complex locus which conditions resistance to the fungus Puccinia sorghi, the causal organism in the common rust disease. Some alleles of Rp1 are meiotically unstable, but the mechanism of instability is not known. We have studied the role of recombination in meiotic instability in maize lines homozygous for either Rp1-J or Rp1-G. Test cr...

Neoliberal austerity has hit hard for people of colour and women living in deprived urban spaces, where we observe unprecedented levels inequality access to care food. In this context, volunteer community services (VCSs) have become fundamental compensating the lack public that support human needs. This article deploys a social reproduction framework analyse andro-white marketization VCSs occur...

Abstract We provide an introduction to this special issue on the politics of COVID-19 pandemic, presenting some key findings and central arguments articles collected herein, discussing their significance in relation broader political context pandemic. address roles necropolitics “necrosecurity”, pointing relationships colonial eugenicist histories, as well ways which a globally-ascendant author...

Abstract This article is an attempt to make sense of the paradox structuring narrative extinction in Alfonso Cuarón’s Children Men (2006), which juxtaposes a romanticized image survival and rebirth ugliness senseless death. Departing from biopolitical framework, argues that story represents as beyond redemption yet subject regulation. Given fact structured around citizen/refugee nexus, I read f...

Little is known about the role of meiotic recombination processes such as unequal crossover in driving instability at tandem repeat DNA. Methods have therefore been developed to detect meiotic crossovers within two different GC-rich minisatellite repeat arrays in humans, both in families and in sperm DNA. Both loci normally mutate in the germline by complex conversion-like transfer of repeats b...

Two gamma 2a gene forms in the MPC11 mouse myeloma cell line (gamma 2b, K) have been localized to the expressed H chain chromosome, where they exist in tandem downstream of the expressed gamma 2b gene. The gamma 2a gene duplication has apparently occurred by spontaneous, unequal sister chromatid exchange (SCE) in a B lymphoid precursor of MPC11 or in MPC11 itself. It is especially significant t...

Inverted repeats (IRs) and trinucleotide repeats (TNRs) that have the potential to form secondary structures in vivo are known to cause genome rearrangements. Expansions of TNRs in humans are associated with several neurological disorders. Both IRs and TNRs stimulate spontaneous unequal sister-chromatid exchange (SCE) in yeast. Secondary structure-associated SCE events occur via double-strand b...
