Characterization of transgenic cotton (Gossypium hirsutum L.) over-expressing Arabidopsis thaliana Related to ABA-insensitive3(ABI3)/Vivparous1 (AtRAV1) and AtABI5 transcription factors: improved water use efficiency through altered guard cell physiology

DOI: 10.1007/s11816-017-0455-6
Abstract: We investigated select transgenic lines of Gossypium hirsutum that over-express AtRAV1 or AtABI5 transcription factors. The hypothesis is that these lines have enhanced responses to abscisic acid (ABA) resulting in greater water use efficiencies (WUE).… read more here.

DOI: 10.1016/j.tplants.2018.06.006
Abstract: It has been demonstrated that ALMT (ALUMINUM-ACTIVATED MALATE TRANSPORTER) channels are important players during stomatal movements. Previous investigations on ALMT family members indicated possible redundancy at the guard cell tonoplast; however, compelling evidence has recently… read more here.

DOI: 10.1038/s41467-022-28263-2
Abstract: Stomatal opening requires the provision of energy in the form of ATP for proton pumping across the guard cell (GC) plasma membrane and for associated metabolic rearrangements. The source of ATP for GCs is a… read more here.

The Solanum tuberosum KST1 partial promoter as a tool for guard cell expression in multiple plant species
Sign Up to like & getrecommendations! Published in 2017 at "Journal of Experimental Botany"
DOI: 10.1093/jxb/erx159
Abstract: The KST1 partial promoter is expressed in guard cells immediately after guard mother cell division and drives constitutive guard cell expression in dicots and monocots, and under drought and ABA treatment. read more here.

DOI: 10.1101/2022.01.11.475946
Abstract: Abscisic acid (ABA) drives stomatal closure to minimize water loss due to transpiration in response to drought. We examined the subcellular location of ABA increased accumulation of reactive oxygen species (ROS) in guard cells that… read more here.

DOI: 10.1104/pp.17.01214
Abstract: Stomatal guard cells are controlled by a modified circadian oscillator to ensure correct daylength-dependent regulation of stomatal aperture. The endogenous circadian (∼24 h) system allows plants to anticipate and adapt to daily environmental changes. Stomatal… read more here.

DOI: 10.1105/tpc.19.00481
Abstract: Silencing phosphoenolpyruvate carboxylase in a Crassulacean acid metabolism species prevented nocturnal CO2 fixation and malate accumulation and perturbed the circadian clock and guard cell signaling. Unlike C3 plants, Crassulacean acid metabolism (CAM) plants fix CO2… read more here.
