Multiple actin isotypes in plants: diverse genes for diverse roles?

Frontiers in Plant Science, 2012
Plant actins are encoded by a gene family. Despite the crucial significance of the actin cytoskeleton for plant structure and function, the importance of individual actin isotypes and their specific roles in various plant tissues or even single cells is ...

Potential applications of Agrobacterium virulence gene promoters in plant-protecting microbial inoculants [PDF]

, 1994
The concept behind this project was to continue the development of strains of Agrobacterium tumefaciens that were capable of producing pesticidal proteins in response to plant wounding, thereby killing the invading organism.

Constitutive expression of a grapevine polygalacturonase-inhibiting protein affects gene expression and cell wall properties in uninfected tobacco [PDF]

, 2011
Background Polygalacturonase-inhibiting proteins (PGIPs) directly limit the effective ingress of fungal pathogens by inhibiting cell wall-degrading endopolygalacturonases (ePGs).

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Promising Biotechnological Applications of the Artificial Derivatives Designed and Constructed from Plant microRNA Genes

Plants
MicroRNAs (miRNAs) are small regulatory RNAs that are expressed in a tissue-specific manner during the development of plants and animals. The genes of miRNAs have been found to produce the following two products: (i) primary transcripts of these genes ...

Transcriptional profiling of plant embryogenesis. [PDF]

, 2005
The process of embryogenesis in higher plants is a critical stage of the sporophytic life cycle, transforming the fertilised egg cell via a precise sequence of events into a multi-cellular organism.

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life

FEBS Letters, EarlyView.
Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

Molecular biology of the Oleosin gene family of Brassica napus [PDF]

, 1991
Oilseed rape (Brassica napus) is a valuable oil producing crop plant. Oil is produced by developing seeds and constitutes 45% of the dry seed weight. Storage oil is deposited as triacylglycerol in spherical structures called oil bodies.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
