Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Floral biology and reproductive mechanisms of Mussambê (Cleome spinosa Jacq) aiming at the plant breeding [PDF]

Biotemas, 2007
Some plants from Cleome genus in Capparaceae family are used as medicinal and ornamental plants. The aim of this work was to study the fl oral biology and the reproductive mechanisms of C. spinosa to the plant breeding. Anthesis occurred between 17:30 to

Screening natural oil palm (Elaeis guineensis Jacq.) populations using SSR markers [PDF]

, 2009
The assessment of genetic diversity and genetic structure of natural oil palm populations is carried out mostly for crop improvement purpose. A set of 16 microsatellite markers was used to genotype 494 palms from 49 populations belonging to ten African ...

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Exaptation and emergence as mechanisms to cross fitness valleys during evolution: an example using simulated homing behaviour [PDF]

, 2008
Evolution is often considered a gradual hill climbing process, slowly increasing the fitness of organisms. I investigate the evolution of homing behaviour in simulated intertidal limpets.

Patterns of Inter-Chromosomal Gene Conversion on the Male-Specific Region of the Human Y Chromosome [PDF]

, 2017
The male-specific region of the human Y chromosome (MSY) is characterized by the lack of meiotic recombination and it has long been considered an evolutionary independent region of the human genome.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Genetic Variation in a Crossing Population of Camellia oleifera Based on ddRAD Sequencing and Analysis of Association with Fruit Traits

Current Issues in Molecular Biology
Tea oil is an important high-quality edible oil derived from woody plants. Camellia oleifera is the largest and most widely planted oil-producing plant in the Camellia genus in China, and its seeds are the most important source for obtaining tea oil.

Optimization Iteration Min-Max Cross Over Genetic Algorithm To Generate Fuzzy membership Function Automatically

Journal of Physics: Conference Series, 2019
Abstract Generating membership function fuzzy for Fuzzy system is important to representative of the problem. Some research generating a membership function automatic had done and still have a problem to generate procces in max iterasi, so that this research will generating membership function fuzzy otomatic used genetic algorithm by ...

Crossing Over…Markov Meets Mendel

PLoS Comput. Biol., 2012
Chromosomal crossover is a biological mechanism to combine parental traits. It is perhaps the first mechanism ever taught in any introductory biology class.
