Alfred Henry Sturtevant (November 21, 1891-April 6, 1970) [PDF]
, 1971 It would be difficult to overestimate the importance of Sturtevant's scientific contributions to the development of present-day genetic concepts. Even so I am reluctant to attempt any such evaluation.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Metastable Evolutionary Dynamics: Crossing Fitness Barriers or Escaping via Neutral Paths?
, 1999 We analytically study the dynamics of evolving populations that exhibit metastability on the level of phenotype or fitness. In constant selective environments, such metastable behavior is caused by two qualitatively different mechanisms. One the one hand,

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Heritability and Genetic Variance Components in Sunflower Single Cross Hybrids [PDF]
Journal of Agricultural Science and Sustainable Production, 2015 In order to estimate genetic parameters in 16 Sunflower single cross hybrids obtained from crossing of 4 cytoplasmic male sterile and 4 fertility restorer lines, a North Carolina Design II was conducted using RCBD design with 3 replications at Khoy ...

A quantum genetic algorithm with quantum crossover and mutation operations
, 2013 In the context of evolutionary quantum computing in the literal meaning, a quantum crossover operation has not been introduced so far. Here, we introduce a novel quantum genetic algorithm which has a quantum crossover procedure performing crossovers ...

Course Timetabling using Genetic Algorithm and Fuzzy Cross-Over
JOIV : International Journal on Informatics VisualizationCourse timetabling at universities presents a complex problem due to the limited timeframe to create schedules that avoid conflicts between activities. This issue becomes more challenging as the number of activities increases while the available rooms remain constant. Numerous studies have attempted to automate the scheduling process, but their success

Genetic Divergence Analysis over Seasons in Single Cross Hybrids of Maize (Zea mays L.)
, 2022 D2 analysis in single cross hybrids of maize over seasons indicated the influence of seasons on clustering patterns based on morpho-physiological and yield components. The cluster analysis assigned the 45 hybrids of maize single cross hybrids into five, six and seven major clusters in rabi, summer, and kharif, respectively based on the quantitative ...

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
