The Biological Bulletin, 1953 1. Conjugating strains representing three different mating types of Tetrahymena pyriformis have been isolated from fresh water ponds in the Woods Hole, Massachusetts, area and established in axenic cultures.2. These strains have the same amino acid and vitamin requirements as T. pyriformis E.3. The cytology of conjugation is described.4.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Mating-type loci of Ustilago esculenta are essential for mating and development
Fungal Genetics and Biology, 2019 Ustilago esculenta is closely related to the smut fungus Ustilago maydis and, in an endophytic-like life in the plant Zizania latifolia, only infects host stems and causes swollen stems to form edible galls called Jiaobai in China. In order to study its different modes of invasion and sites of symptom development from other smut fungi at the molecular ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

, 2021 In heterothallic basidiomycete fungi, sexual compatibility is restricted by mating types, typically controlled by two loci: PR, encoding pheromone precursors and pheromone receptors, and HD, encoding two types of homeodomain transcription factors.

, 2015 Comparison of allele frequencies within MATa and MATα populations revealed loci that affect growth in a mating type dependent manner. The QTL on chromosome 8 encompasses GPA1, a negative regulator of the mating pathway that affects fitness in different ...

Mating types and macrocyst formation in Dictyostelium [PDF]
Journal of Bacteriology, 1981 Macrocysts have been found among strains of Dictyostelium rosarium Raper and Cavender (K. B. Raper and J. C. Cavender, J. Elisha Mitchell Sci. Soc. 84:31-47, 1968). Strains that exhibit mating capabilities could be classified into one of three mating types: A1, A2, or A3.

Molecular Oncology, EarlyView.In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Antigens and Mating Types in Escherichia coli [PDF]
Nature, 1956 EVIDENCE has been offered by one of us1 for the existence of properties correlated with sex compatibility in Escherichia coli. According to these data, sex-incompatible (F −) strains have a lower acid agglutination point and a far greater stability of broth-cultures as compared with F + strains of corresponding phenotype.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers
Molecular Oncology, EarlyView.This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...
