Salt glands in exo‐recretohalophytes: Development, physiological functions, and prospects for improving crop salt tolerance

Journal of Integrative Plant Biology, EarlyView.
This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

Proton-translocating ATPase from bovine kidney medulla: partial purification and reconstitution

, 1988
The proton-translocating ATPase that is responsible both for urinary and vacuolar acidification was partially purified from bovine kidney medulla microsomes.

Proton-translocating ATPase and lysosomal cystine transport.

Journal of Biological Chemistry, 1983
A proton-translocating ATPase was identified in highly purified lysosomes from Epstein-Barr virus-transformed human lymphoblasts. Activity of this ATPase caused acidification of highly purified, fluorescein isothiocyanate dextran-loaded lysosomes and correlated with the ATP-dependent efflux of lysosomal cystine.

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 ...

Vacuolar Acidification and Bafilomycin-Sensitive Proton Translocating ATPase in Human Epidermal Langerhans Cells

, 1991
Langerhans cells (LC) are the principal antigen-presenting cells (APC) of squamous epithelia, We have previously Shown that freshly isolated LC (fLC) are able to deliver endocytosed membrane MHC class II molecules into acidic environments, and that this ...

The proton translocating ATPase responsible for urinary acidification.

Journal of Biological Chemistry, 1982
H+ secretion by the turtle urinary bladder is produced by a proton pump located in the luminal membrane. We show that a microsomal fraction of these cells contains an electrogenic proton translocating ATPase that is inhibited by dicyclohexylcarbodiimide but not oligomycin or vanadate.

Genomic variation drives plant flavor diversification

Journal of Integrative Plant Biology, EarlyView.
This review explains how genomic variation shapes plant flavor by altering the biosynthetic and regulatory pathways of key attributes like sweetness, acidity, bitterness, piquancy, astringency, and aroma. It also discusses how multi‐omics, AI‐assisted breeding, and gene editing can translate this knowledge into plants with improved flavor, nutrition ...

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

The archaeal P-type ATPases.

, 2004
A phylogenetic analysis was carried out of a total of 58 P-type ATPases encoded within the genomes of 20 archaea species. Members from six subfamilies were identified including: putative metal-, proton-, calcium-, sodium/potassium-, potassium-, and ...

Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (
