Biogenic retrograde signaling via GUN1 ensures thermotolerant chloroplast biogenesis during seedling establishment in Arabidopsis thaliana

Journal of Integrative Plant Biology, EarlyView.
Under heat stress, GENOMES UNCOUPLED1 (GUN1) is crucial for the formation of functional chloroplasts in seedlings under heat stress. Without GUN1, chloroplast development fails and seedlings fail to turn green. Therefore, GUN1 helps relay heat‐related cues to maintain chloroplast biogenesis and support thermotolerance during early growth.

STN7 operates in retrograde signalling through controlling redox balance in the electron transfer chain

Frontiers in Plant Science, 2012
Phosphorylation of the major photosynthetic light harvesting antenna proteins by STN7 kinase balances excitation between PSII and PSI. Phosphorylation of such abundant proteins is unique, differing distinctively from conventional tasks of protein kinases

Thermoluminescence in Chloroplast Thylakoid [PDF]

, 2012
Luminescence occurs in almost all the materials absorbing photon energy and is a phenomenon of light emitting process. There are various types of luminescence, e.g. fluorescence, phosphorescence, delayed luminescence, chemiluminescence and thermoluminescence.

When chemistry meets taxonomy: Studying glycolipidic chemomarkers in pelagic Sargassum spp. (Phaeophyceae) using molecular networking

Journal of Phycology, EarlyView.
Abstract To chemically differentiate the three pelagic Sargassum morphotypes co‐occurring in floating rafts and drifting across the Atlantic Ocean before stranding on West African, Caribbean, and Atlantic Mexican coastlines, we conducted an investigation of their metabolomic profiles.

Starch synthesis in Brachypodium distachyon endosperm occurs in dynamic, connected amyloplast compartments

New Phytologist, EarlyView.
Summary The morphology of starch granules is a major determinant of the functional and nutritional properties of starch and is highly variable among cereal species. Much of this morphological variation stems from differences in the spatial and temporal patterns of starch granule initiation in amyloplasts during grain development.

Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, EarlyView.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

Rice MGD1‐Mediated Improvement of Photosynthesis and Crop Yield by Flexible Adaptation to Different Light Conditions

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flexible adaptation to different light intensities found in natural environments is crucial for efficient photosynthesis and yield production in crops. The ability to cope with suboptimal light conditions effectively and efficiently is clearly advantageous.

Natural Variation in TaFAD8‐D Promoter Enhances Thermotolerance in Wheat Through Fatty Acid and Lipid Remodelling

Plant Biotechnology Journal, EarlyView.
ABSTRACT Heat stress (HS) has become an increasing threat to wheat productivity under global warming. However, the genetic loci for thermotolerance and the underlying molecular mechanisms remain largely unknown. In this study, genetic mapping identified a thermotolerance locus, QMpe.cau‐2D, encoding fatty acid desaturase 8 (FAD8), with the transposable
