The multidimensional regulation roles and mechanisms of calcium in fruit quality

Journal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

The physical and functional borders of transit peptide-like sequences in secondary endosymbionts

BMC Plant Biology, 2010
Background Plastids rely on protein supply by their host cells. In plastids surrounded by two membranes (primary plastids) targeting of these proteins is facilitated by an N-terminal targeting signal, the transit peptide.

Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

Journal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

The induction of stromule formation by a plant DNA-virus in epidermal leaf tissues suggests a novel intra- and intercellular macromolecular trafficking route

Frontiers in Plant Science, 2012
Stromules are dynamic thin protrusions of membrane envelope from plant cell plastids. Despite considerable progress in understanding the importance of certain cytoskeleton elements and motor proteins for stromule maintenance, their function within the ...

Pentatricopeptide repeat proteins in crops: Advances in functional mechanisms and breeding applications

Journal of Integrative Plant Biology, EarlyView.
Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...

A potential cyanobacterial ancestor of Viridiplantae chloroplasts

, 2011
The theory envisaging the origin of plastids from endosymbiotic cyanobacteria is well-established but it is difficult to explain the evolution (spread) of plastids in phylogenetically diverse plant groups.

OsCPN10a, cooperating with OsCPN20 and OsHSP60‐3B negatively regulate ABA signaling and enhance seed storability in rice

Journal of Integrative Plant Biology, EarlyView.
Abscisic acid signaling homeostasis is essential for seed storability. The molecular chaperone OsCPN10a enhances rice seed storability by forming a trimeric chaperone complex with OsCPN20‐OsHSP60‐3B that attenuates abscisic acid signaling via direct interaction with OsPYL10‐OsABIL1, thereby maintaining starch integrity and offering a promising target ...

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

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.
