Food Frontiers, Volume 7, Issue 4, July 2026.ABSTRACT Grape marc (GM) is a polyphenol‐rich winery byproduct that remains underutilized due to its complex fiber matrix, which limits the bioaccessibility of bound phenolics. While lactic acid fermentation (LAF) can enhance the release of these compounds, the strain‐specific metabolic fate of GM phenolics during digestion and colonic fermentation ...

Working model for the role of PAPP5 in tetrapyrrole mediated plastid signalling. [PDF]
, 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.

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.Overexpression of CsNBR1 confers HLB resistance in citrus by degrading CLas effector proteins, including SDE5115, SDE1, SDE19 and SDE5, via the autophagy pathway. ABSTRACT The selective autophagy receptor NEIGHBOUR OF BRCA1 (NBR1) is a key regulator of plant immunity, but its role against bacterial pathogens remains poorly understood.

The Alternative Haem Biosynthesis Pathway: Structure, Function and Properties of Sirohaem Decarboxylase [PDF]
, 2014 Haem, a cyclic tetrapyrrole, is found in organisms from all three domains of life. Haem is a prosthetic group for many proteins involved in essential biological processes such as respiration and oxygen transport.

Conformational heterogeneity of the Pfr chromophore in plant and cyanobacterial phytochromes
Frontiers in Molecular Biosciences, 2015 Phytochromes are biological photoreceptors that can be reversibly photoconverted between a dark and photoactivated state. The underlying reaction sequences are initiated by the photoisomerisation of the tetrapyrrole cofactor, which in plant and ...

Decoding GUN1 in plastid‐to‐nucleus signaling: what it doesn't, what it does, and why it matters
New Phytologist, Volume 251, Issue 1, Page 81-88, July 2026.Publication history of plant GUN1 research. Summary Plastid‐to‐nucleus retrograde signaling coordinates nuclear gene expression with the developmental and physiological state of plastids. GENOMES UNCOUPLED 1 (GUN1), a chloroplast‐localized PPR‐SMR protein, remains a central yet poorly understood component of this network.

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4577-4598, July 2026.ABSTRACT Cold stress threatens wheat productivity, particularly in regions with extreme climatic conditions. To elucidate the molecular mechanisms underlying wheat's response to cold stress, we performed a multiomics analysis integrating lipidomics, transcriptomics, proteomics and metabolomics.

Evolution of the Tetrapyrrole Biosynthetic Pathway in Secondary Algae: Conservation, Redundancy and Replacement. [PDF]
PLoS ONE, 2016 Tetrapyrroles such as chlorophyll and heme are indispensable for life because they are involved in energy fixation and consumption, i.e. photosynthesis and oxidative phosphorylation.
