High-resolution temporal profiling of transcripts during Arabidopsis leaf senescence reveals a distinct chronology of processes and regulation [PDF]

, 2011
Leaf senescence is an essential developmental process that impacts dramatically on crop yields and involves altered regulation of thousands of genes and many metabolic and signaling pathways, resulting in major changes in the leaf.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Dynamics of DNA Methylation and Its Functions in Plant Growth and Development

Frontiers in Plant Science, 2021
Epigenetic modifications in DNA bases and histone proteins play important roles in the regulation of gene expression and genome stability. Chemical modification of DNA base (e.g., addition of a methyl group at the fifth carbon of cytosine residue ...

Enhancer mediated regulation of developmental gene expression

The FASEB Journal, 2012
Cell‐fate transitions involve the integration of genomic information encoded by regulatory elements, such as enhancers, with cellular and signaling environments. Identification of genomic sequences that control human embryonic development represents a formidable challenge, as they are embedded within a vast non‐coding genomic space.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Spatiotemporal expression patterns of cytosolic AtHSP90-2 in Arabidopsis seedlings

Plant Signaling & Behavior, 2023
Heat shock protein AtHSP90–2 is one of the three constitutive cytosolic HSP90s of Arabidopsis thaliana, which are highly homologous and show mild expression activation in response to stressful impacts.

A specific group of genes respond to cold dehydration stress in cut Alstroemeria flowers whereas ambient dehydration stress accelerates developmental senescence expression patterns [PDF]

, 2010
Petal development and senescence entails a normally irreversible process. It starts with petal expansion and pigment production, and ends with nutrient remobilization and ultimately cell death.

Zebrafish churchill regulates developmental gene expression and cell migration [PDF]

Developmental Dynamics, 2013
Background: Regulation of developmental signaling pathways is essential for embryogenesis. The small putative zinc finger protein, Churchill (ChCh) has been implicated in modulation of both TGF‐β and FGF signaling. Results: We used zinc finger nuclease (ZFN) mediated gene targeting to disrupt the zebrafish chch locus and generate the first chch ...

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.
