Protoplasma
. 2025 Feb;
PMID: 39894892
Myrosinase, referred to as thioglucoside glucohydrolase (TGG), plays a crucial role in plant physiology through catalyzing the hydrolysis of glucosinolates into bioactive isothiocyanates. In Arabidopsis thaliana, the myrosinases TGG1 and...

. 2020 Nov;
71(22):6921-6931.
PMID: 33252127
Allyl isothiocyanate (AITC) induces stomatal closure accompanied by reactive oxygen species (ROS) production and glutathione (GSH) depletion in Arabidopsis thaliana. In this study, stomatal responses to three other isothiocyanates (ITCs),...

Plant Cell Physiol
. 2020 Aug;
61(10):1788-1797.
PMID: 32810268
Production of reactive oxygen species (ROS) is a key signal event for methyl jasmonate (MeJA)- and abscisic acid (ABA)-induced stomatal closure. We recently showed that reactive carbonyl species (RCS) stimulates...

Biosci Biotechnol Biochem
. 2020 Jul;
84(11):2281-2292.
PMID: 32729395
Selenium (Se) causes oxidative damage to plants. Proline is accumulated as a compatible solute in plants under stress conditions and mitigates stresses. Selenate at 250 µM increased cell death and...

Plant Cell
. 2020 Apr;
32(7):2216-2236.
PMID: 32327536
Upon recognition of microbes, pattern recognition receptors (PRRs) activate pattern-triggered immunity. FLAGELLIN SENSING2 (FLS2) and BRASSINOSTEROID INSENSITIVE1-ASSOCIATED KINASE1 (BAK1) form a typical PRR complex that senses bacteria. Here, we report...

. 2020 Feb;
71(10):2922-2932.
PMID: 32103265
The glucosinolate-myrosinase system is a well-known defense system that has been shown to induce stomatal closure in Brassicales. Isothiocyanates are highly reactive hydrolysates of glucosinolates, and an isothiocyanate, allyl isothiocyanate...

Plant Cell Physiol
. 2019 Feb;
60(5):1146-1159.
PMID: 30796836
We have demonstrated that reactive carbonyl species (RCS) function as an intermediate downstream of hydrogen peroxide (H2O2) production in abscisic acid (ABA) signaling for stomatal closure in guard cells using...

New Phytol
. 2017 Dec;
218(1):253-268.
PMID: 29250804
Stomatal immunity restricts bacterial entry to leaves through the recognition of microbe-associated molecular patterns (MAMPs) by pattern-recognition receptors (PRRs) and downstream abscisic acid and salicylic acid signaling. Through a reverse...

Nat Commun
. 2017 Nov;
8(1):1284.
PMID: 29101334
Stomata regulate gas exchange between plants and atmosphere by integrating opening and closing signals. Stomata open in response to low CO concentrations to maximize photosynthesis in the light; however, the...

Plant Cell Physiol
. 2017 Apr;
58(6):1048-1058.
PMID: 28407091
Stomata within the plant epidermis regulate CO2 uptake for photosynthesis and water loss through transpiration. Stomatal opening in Arabidopsis thaliana is determined by various factors, including blue light as a...
