In flowering plants the gynoecium is the female reproductive structure. In Arabidopsis thalianaovules initiate within the developing gynoecium from meristematic tissue located along the margins of the floral carpels. When fertilized the ovules will develop into seeds. SEUSS (SEU) and AINTEGUMENTA (ANT) encode transcriptional regulators that are critical for the proper formation of ovules from the carpel margin meristem (CMM). The synergistic loss of ovule initiation observed in the seu ant double mutant suggests that SEU and ANT share overlapping functions during CMM development. However the molecular mechanism underlying this synergistic interaction is unknown. Using …

Serine/threonine (S/T) protein kinases are crucial components of diverse signaling pathways in eukaryotes, including the model filamentous fungus Neurospora crassa. In order to assess the importance of S/T kinases to Neurospora biology, we embarked on a global analysis of 86 S/T kinase genes in Neurospora. We were able to isolate viable mutants for 77 of the 86 kinase genes. Of these, 57% exhibited at least one growth or developmental phenotype, with a relatively large fraction (40%) possessing a defect in more than one trait. S/T kinase knockouts were subjected to chemical screening using a panel of eight chemical treatments, with …

Alzheimer's disease is a devastating disease, affecting millions. There is some familial evidence of an inheritance pattern from a genetic basis in Alzheimer's disease patients, but even with revelation of the genetic linkage and genes associated with Alzheimer's disease, the inheritance pattern is too complicated to be properly explained. It is necessary to investigate other causes of the debilitating disease. To investigate further, the epigenome was studied - the regulation of the genome by methyl group addition.
To study the epigenome of an Alzheimer's disease-like state, isoschizomer enzymes were used to cleave CC*GG regions. Comparing the cleaved DNA sequences produced …
