SIB1‐SEC23A undergo ER to chloroplast relocalization to mediate immunity in Arabidopsis thaliana

Journal of Integrative Plant Biology, EarlyView.
SEC23A mediates membrane trafficking between the endoplasmic reticulum (ER) and Golgi apparatus and interacts with the immunity protein SIGMA FACTOR‐BINDING PROTEIN1 in Arabidopsis. Under stress, both proteins relocate from the ER to chloroplasts, suppressing photosynthesis genes and enhancing defense genes.

Uncovering the role of the PPR protein PHOTOSYSTEM ONE BIOGENESIS FACTOR6 in splicing chloroplast group II introns

Journal of Integrative Plant Biology, EarlyView.
The P‐class pentatricopeptide repeat (PPR) protein PHOTOSYSTEM ONE BIOGENESIS FACTOR (PBF6) forms splicing complexes with other known splicing factors to facilitate chloroplast intron splicing. PBF6 cooperates with other PPR splicing factors to promote the splicing of the same intron through forming respective splicing complexes.

Chloroplast and mitochondrial genomes of Sphaerosorus coelastroides Pascher (Xanthophyceae) from Central Appalachia, Clinch River, Virginia, United States

Journal of Phycology, EarlyView.
Abstract This report describes the isolation and culture of Sphaerosorus coelastroides from the plankton of a freshwater river in the central Appalachian mountain chain. This alga was first observed in a dry freshwater riverbed in Central Europe in 1908 and, since then, has been included in Xanthophyceae surveys from nearly all continents with ...

Drought and salinity stress remodel Asian rice (Oryza sativa) leaf development through cell‐type‐specific regulatory programs

New Phytologist, EarlyView.
Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...

Identification and roles of Photosystem II assembly, stability, and repair factors in Arabidopsis

Frontiers in Plant Science, 2016

Special Delivery: A Crucial Protein That Transports Manganese to the Oxygen-Evolving Complex of Photosystem II [PDF]

The Plant Cell, 2016
Deep in the thylakoid membrane, the key process that produces breathable oxygen in the Earth’s atmosphere takes place, namely, the splitting of water molecules and the subsequent release of molecular oxygen.

Systemic acquired resistance: an emerging role for jasmonates in local signal biogenesis, translocation and distal signal decoding

New Phytologist, EarlyView.
Jasmonate signalling underpins establishment of plant systemic acquired resistance (SAR). Activation of the hypersensitive response (HR) not only contains the pathogen but establishes broad spectrum resistance in unchallenged leaves. The strong burst of reactive oxygen/nitrogen species initiating the HR results in lipid peroxidation (illustrated by ...

Disruption of starch biosynthesis and triacylglycerol degradation impairs growth but improves photosynthesis in Arabidopsis

New Phytologist, EarlyView.
Proposed model for altered carbon partitioning in wild‐type (a) and tgd1 sdp1 adg1‐1 Arabidopsis triple mutant (b). Summary Enhancing lipid accumulation by redirecting carbon from starch to triacylglycerol (TAG) in vegetative tissues is a promising strategy for developing high‐energy‐density crops for bioenergy production. However, our understanding of

Quantitation of Cytochromes b559, b6, and f, and the Core Component of Photosystem I P700 in Cyanobacterial Cells

Bio-Protocol, 2016
Cytochrome (Cyt) b559, an important and essential core component of photosystem II in the photosynthetic electron transport system, is a heme-bridged heterodimer protein composed of an alpha subunit (PsbE) and a beta subunit (PsbE), and its reduced form ...

Desiccation tolerance mechanisms in the green lineage and beyond

New Phytologist, EarlyView.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...
