Characterization of a novel R98Q mutation that confers resistance to sulfentrazone in common ragweed (Ambrosia artemisiifolia) populations from Michigan

Pest Management Science, EarlyView.
Field‐collected Ambrosia artemisiifolia populations from Michigan, USA, soybean fields exhibited strong resistance to the protoporphyrinogen IX oxidase (PPO)‐inhibiting herbicide sulfentrazone and reduced sensitivity to fomesafen. Target‐site analysis identified a novel Arg‐98‐Gln (R98Q) substitution in PPO2, co‐occurring with the previously reported ...

Fendioxypyracil exhibits potent inhibition of PPO‐resistant mutant enzymes and robust activity against PPO‐resistant Amaranthus spp.

Pest Management Science, EarlyView.
Fendioxypyracil maintained potent activity across major PPX2 target‐site resistance mutations, with consistent efficacy from enzyme inhibition to whole‐plant response. Greenhouse and field evaluations further demonstrated effective control of PPO‐resistant Palmer amaranth (Amaranthus palmeri).

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Working model for the role of PAPP5 in tetrapyrrole mediated plastid signalling.

, 2013
PAPP5 pereceives an inbalance in the tetrapyrrole biosynthesis through the accumulation of Mg-ProtoIX/Mg-ProtoIXME and acts as a negative regulator of chloroplast biogenesis and development.

Localization of heme biosynthesis in the diatom Phaeodactylum tricornutum and differential expression of multi-copy enzymes

Frontiers in Plant Science
Heme is essential for all organisms. The composition and location of the pathway for heme biosynthesis, have been influenced by past endosymbiotic events and organelle evolution in eukaryotes.

Saturating mutagenesis on the Ser118 residue responsible for the spectral tuning mechanism of the orange/green‐reversible cyanobacteriochrome AM1_1499g1

Plant Biology, EarlyView.
This graphical abstract illustrates our systematic site‐saturation mutagenesis at the Ser118 position of the AM1_1499g1 GAF domain. By replacing this single residue, we generated a diverse array of variants with distinct spectral properties, demonstrating the remarkable molecular plasticity of cyanobacteriochromes and their customizability for ...

Lineare Tetrapyrrole in marinen Sedimenten [PDF]

, 2001
Ende der 80iger Jahre wurde zum ersten Mal über lineare Tetrapyrrole als Abbauprodukte des Chlorophylls in seneszenten Pflanzen berichtet. Da jährlich mehr als 10 9 t Chlorophyll katabolisiert werden, davon etwa 3/4 im wäßrigen Milieu, stellt sich die ...
