Plant organelle RNA editing and its specificity factors: enhancements of analyses and new database features in PREPACT 3.0

open access: yesBMC Bioinformatics, 2018
Background Gene expression in plant chloroplasts and mitochondria is affected by RNA editing. Numerous C-to-U conversions, accompanied by reverse U-to-C exchanges in some plant clades, alter the genetic information encoded in the organelle genomes ...

Construction of a Codon-Adapted Nourseotricin-Resistance Marker Gene for Efficient Targeted Gene Deletion in the Mycophenolic Acid Producer Penicillium brevicompactum

open access: yesJournal of Fungi, 2019
Penicillium brevicompactum is a filamentous ascomycete used in the pharmaceutical industry to produce mycophenolic acid, an immunosuppressant agent. To extend options for genetic engineering of this fungus, we have tested two resistance markers that have

An unusual growth form of Cladonia furcata: The trampling-resistant primary thallus colonizing a paved pathway [PDF]

open access: yes, 1998
Lichens are well known to be susceptible to damage by trampling. Fruticose species, with their highly branched structure, are particularly sensitive and Bayfield et al. (1981) described substantial damage to Cladonia uncialis, C.

Physcomitrium patens Mutants in Auxin Conjugating GH3 Proteins Show Salt Stress Tolerance but Auxin Homeostasis Is Not Involved in Regulation of Oxidative Stress Factors

open access: yesPlants, 2021
Salt stress is among the most challenging abiotic stress situations that a plant can experience. High salt levels do not only occur in areas with obvious salty water, but also during drought periods where salt accumulates in the soil.

The Clubroot Pathogen (Plasmodiophora brassicae) Influences Auxin Signaling to Regulate Auxin Homeostasis in Arabidopsis

open access: yesPlants, 2013
The clubroot disease, caused by the obligate biotrophic protist Plasmodiophora brassicae, affects cruciferous crops worldwide. It is characterized by root swellings as symptoms, which are dependent on the alteration of auxin and cytokinin metabolism ...

Homologous Proteins of the Manganese Transporter PAM71 Are Localized in the Golgi Apparatus and Endoplasmic Reticulum

open access: yesPlants, 2020
Chloroplast manganese transporter 1 (CMT1) and photosynthesis-affected mutant 71 (PAM71) are two membrane proteins that function sequentially to mediate the passage of manganese across the chloroplast envelope and the thylakoid membrane.
