Enhanced secretion through type 1 secretion system by grafting a calcium‐binding sequence to modify the folding of cargo proteins Open
Extracellular secretion is a beneficial way to produce recombinant proteins at an industrial scale. Among bacterial secretion systems, the type 1 secretion system (T1SS) in Gram‐negative bacteria is particularly attractive due to its simpl…

View article: Distinct gibberellin functions during and after grapevine bud dormancy release
Distinct gibberellin functions during and after grapevine bud dormancy release Open
The molecular mechanism regulating dormancy release in grapevine buds is as yet unclear. It has been hypothesized that (i) abscisic acid (ABA) represses bud-meristem activity; (ii) perturbation of respiration induces an interplay between e…

The reduction in maize leaf growth under mild drought affects the transition between cell division and cell expansion and cannot be restored by elevated gibberellic acid levels Open
Summary Growth is characterized by the interplay between cell division and cell expansion, two processes that occur separated along the growth zone at the maize leaf. To gain further insight into the transition between cell division and ce…

Abnormal Endogenous Repression of GA Signaling in a Seedless Table Grape Cultivar with High Berry Growth Response to GA Application Open
Gibberellin (GA) application is routinely used in the table grape industry to increase berry size and cluster length. Although grapevine cultivars show a wide range of growth responsiveness to GA3 application, the reasons for th…

Analysis of plant hormone profiles in response to moderate dehydration stress Open
Summary Plant responses to dehydration stress are mediated by highly complex molecular systems involving hormone signaling and metabolism, particularly the major stress hormone abscisic acid ( ABA ) and ABA ‐dependent gene expression. To u…

The ERF11 Transcription Factor Promotes Internode Elongation by Activating Gibberellin Biosynthesis and Signaling Open
The phytohormone gibberellin (GA) plays a key role in promoting stem elongation in plants. Previous studies show that GA activates its signaling pathway by inducing rapid degradation of DELLA proteins, GA signaling repressors. Using an act…

Highly Sprouting-Tolerant Wheat Grain Exhibits Extreme Dormancy and Cold Imbibition-Resistant Accumulation of Abscisic Acid Open
Pre-harvest sprouting (PHS) of wheat (Triticum aestivum L.) grains induces hydrolyzing enzymes such as α-amylase, which considerably decreases wheat product quality. PHS occurs when cool and wet weather conditions before harvest break dorm…

Binding of GID1 to DELLAs promotes dissociation of GAF1 from DELLA in GA dependent manner Open
Gibberellins (GAs) are important phytohormones for plant growth and development. DELLAs are members of the plant-specific GRAS protein family and act as repressors of GA signaling. DELLAs are rapidly degraded in the presence of GAs. GA-GID…
