The Arabidopsis Na+/H+ Antiporters NHX1 and NHX2 Control Vacuolar pH and K+ Homeostasis to Regulate Growth, Flower Development, and Reproduction[C][W]
TLDR
The roles of NHX1 and NHX2 are demonstrated in regulating intravacuolar K+ and pH, which are essential to cell expansion and flower development, and growth under added Na+, but not K+, partly rescued the flower and growth phenotypes. Expand
Differential expression and internal feedback regulation of 1-aminocyclopropane-1-carboxylate synthase, 1-aminocyclopropane-1-carboxylate oxidase, and ethylene receptor genes in tomato fruit during
TLDR
The results suggest that in tomato fruit the preclimacteric system 1 ethylene is possibly mediated via constitutively expressed LE-ACS1A and LE- ACS3 and negatively feedback-regulated LE-acS6 genes with preexisting Le-ACO1 and LE -ACO4 mRNAs as a result of a positive feedback regulation. Expand
Primary structural features of the S haplotype-specific F-box protein, SFB, in Prunus
TLDR
Evidence of positive selection was detected using maximum likelihood methods with sites under positive selection concentrated in the variable and hypervariable regions of Prunus SFBs. Expand
Ethylene regulation of fruit softening and cell wall disassembly in Charentais melon.
TLDR
The hypothesis that while individual cell wall-modifying proteins from each family contribute to cell wall disassembly that accompanies fruit softening, other closely related family members are regulated in an ethylene-independent manner and apparently do not directly participate in fruitsoftening is supported. Expand
Ripening-associated ethylene biosynthesis in tomato fruit is autocatalytically and developmentally regulated
TLDR
The results suggest that ripening-associated ethylene (system 2) in wild-type tomato fruit consists of two parts: a small part regulated by a developmental factor through the ethylene-independent expression of LeACS2 andLeACS4 and a large partregulated by an autocatalytic system due to the ethane-dependent expression of the same genes.

GNOM-LIKE1/ERMO1 and SEC24a/ERMO2 Are Required for Maintenance of Endoplasmic Reticulum Morphology in Arabidopsis thaliana[W]
TLDR
It is suggested that GNL1/ER MO1 and SEC24a/ERMO2 have a novel function in ER morphology in higher plants, similar to that in yeast and animal cells. Expand
Ethylene is required for both the initiation and progression of softening in pear (Pyrus communis L.) fruit.
TLDR
The results suggest that ethylene is required for PGs expression even in the late ripening stage, but not for EGases, and suggest that Ethylene in ripening is regulated entirely in an autocatalytic manner. Expand
Differential feedback regulation of ethylene biosynthesis in pulp and peel tissues of banana fruit.
TLDR
The results suggest that ethylene biosynthesis in ripening banana fruit may be controlled negatively in the pulp tissue and positively in the peel tissue. Expand
Low-temperature-modulated fruit ripening is independent of ethylene in ‘Sanuki Gold’ kiwifruit
TLDR
Surprisingly, significant fruit softening, mRNA accumulation of AC-PG, AC-PL, and AC-EXP, and decreased TA were observed without ethylene production in intact Fruit stored at low temperature for 1 month, but not in fruit stored at room temperature. Expand
Ethylene Biosynthesis in Detached Young Persimmon Fruit Is Initiated in Calyx and Modulated by Water Loss from the Fruit1
TLDR
Ethylene biosynthesis in detached young persimmon fruit is initially induced in calyx and is modulated by water loss through transcriptional activation of DK-ACS2, which acts as a secondary signal that stimulates autocatalytic ethylene bios synthesis in these tissues, leading to a burst of ethylene production.
