The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Glacial cycles promote greater dispersal, which can help explain larger clutch sizes, in north temperate birds [PDF]

, 2009
Earth’s glacial history and patterns in the life history traits of the planet’s avifauna suggest the following interpretations of how recent geological history has affected these key characteristics of the biota: 1) Increased colonizing ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Evaluation and variability studies in local types of brinjal for yield and quality (Solanum melongena L.) [PDF]

Electronic Journal of Plant Breeding, 2012
Mean performance and genetic variability parameters were estimated in 33 local types of brinjal to identify suitable parentsfor hybridization. The study revealed that highly significant differences were observed for most of the traits.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

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.

Variability studies of quantitative characters in Maize (Zea mays L.) [PDF]

Electronic Journal of Plant Breeding, 2012
One hundred and forty four maize inbreds were evaluated for 15 different quantitative characters. Analysis of variance andthe phentotypic range showed the availability of considerable variation for all the characters studied.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Variability and transgressive segregation for yield and yield contributing traits in pigeonpea crosses [PDF]

Electronic Journal of Plant Breeding, 2014
In the present study F2 and F3 generations were evaluated for yield and yield contributing traits to understand genetic variability and to identify transgressive segregants in three pigeonpea crosses.
