“…The stomatal development pathway is unique, in that the Gα and the Gβ proteins have an additive effect (Figure ). Although the genetic pathways underlying stomatal development have been elucidated in exquisite detail (Dong and Bergmann, ; Han and Torii, ; Qu et al , ), how G‐proteins interact with them is completely unknown. Further studies that are focused toward genetic interactions of stomatal development network and G‐proteins would be able to address these questions.…”

Summary Plants being sessile integrate information from a variety of endogenous and external cues simultaneously to optimize growth and development. This necessitates the signaling networks in plants to be highly dynamic and flexible. One such network involves heterotrimeric G‐proteins comprised of Gα, Gβ, and Gγ subunits, which influence many aspects of growth, development, and stress response pathways. In plants such as Arabidopsis, a relatively simple repertoire of G‐proteins comprised of one canonical and three extra‐large Gα, one Gβ and three Gγ subunits exists. Because the Gβ and Gγ proteins form obligate dimers, the phenotypes of plants lacking the sole Gβ or all Gγ genes are similar, as expected. However, Gα proteins can exist either as monomers or in a complex with Gβγ, and the details of combinatorial genetic and physiological interactions of different Gα proteins with the sole Gβ remain unexplored. To evaluate such flexible, signal‐dependent interactions and their contribution toward eliciting a specific response, we have generated Arabidopsis mutants lacking specific combinations of Gα and Gβ genes, performed extensive phenotypic analysis, and evaluated the results in the context of subunit usage and interaction specificity. Our data show that multiple mechanistic modes, and in some cases complex epistatic relationships, exist depending on the signal‐dependent interactions between the Gα and Gβ proteins. This suggests that, despite their limited numbers, the inherent flexibility of plant G‐protein networks provides for the adaptability needed to survive under continuously changing environments.

“…Importantly, these bHLH genes are conserved across the land plants, from moss, ferns, to flowering plants, including monocots (Liu et al 2009;Peterson et al 2010;Ran et al 2013;Raissig et al 2016;Chater et al 2017;Qu et al 2017). In rice, maize, and Brachypodium, there are two copies of SPCH and a single copy of MUTE and FAMA in the gnome (Qu et al 2017). In rice, all of these bHLH proteins, OsSPCH1/2, OsMUTE, and OsFAMA possess a crucial role in stomatal development (Liu et al 2009).…”

Stomata are small pores on the surface of land plants that facilitate gas exchange-acquiring CO 2 from surrounding atmosphere and releasing water vapor. In adverse conditions, such as drought, stomata close to minimize water loss. The activities of stomata are vital for plant growth and survival. In the last two decades, key players for stomatal development have been discovered thanks to the model plant Arabidopsis thaliana. Our knowledge about the formation of stomata and their response to environmental changes are accumulating. In this review, we summarize the genetic and molecular mechanisms of stomatal development, with specific emphasis on recent findings and potential applications toward enhancing the sustainability of agriculture.

“…The heterodimers of basic Helix-Loop-Helix (bHLH) transcription factors specify stomatal precursor cell states (Weintraub et al, 1991). In different developmental stages, two universal components, SCRM/ICE1 and SCRM2, bind with different members of bHLH subgroup Ia SPEECHLESS (SPCH), MUTE, and FAMA, which were recently renamed as SMFs (SPCH, MUTE, FAMA) (Qu et al, 2017). The interactions of ICE1/SCRM2 and SPEECHLESS (SPCH), MUTE, and FAMA promote MMC, GMC and MGC stages respectively (Ohashi-Ito and Bergmann, 2006;Macalister et al, 2007;Pillitteri et al, 2007;Kanaoka et al, 2008).…”

“…The Mitogen-Activated Protein Kinase (MAPK) cascade, including the MAPKKK/Embryo Defective71 (YODA), MPKK4/5, and MAPK MPK3/6, are also involved in this process to inhibit stomatal development and epidermal patterning (Lampard et al, 2008(Lampard et al, , 2009Hara et al, 2009;Lee et al, 2015). In Arabidopsis, the polarity protein BASL serves as the scaffold for the MAPK kinase cascade, which determines asymmetric cell division (Dong et al, 2009;Zhang et al, 2015;Qu et al, 2017). In addition, proteins of BREVIS RADIX (AtBRX)like family and Polar Localization during Asymmetric Division and Redistribution (POLAR) family have been confirmed to play key roles in stomatal development and epidermal patterning (Nunes et al, 2019).…”

“…We hypothesized that relevant gene families [e.g., SPCH, MUTE, FAMA (SMFs), Breaking of Asymmetry in the Stomatal Lineage (BASLs), and PANGLOSS (PANs)] determine stomatal structure and development, which may further influence stomatal movement and potentially regulate WUE in plants Li et al, 2017;Lawson and Vialet-Chabrand, 2018). For more comprehensive reviews of stomatal development and function, the readers are directed to the following excellent articles (Qu et al, 2017;Hepworth et al, 2018;Faralli et al, 2019;Lawson and Vialet-Chabrand, 2018;Tardieu et al, 2018;Leakey et al, 2019).…”

It has been increasingly important for breeding programs to be aimed at crops that are capable of coping with a changing climate, especially with regards to higher frequency and intensity of drought events. Grass stomatal complex has been proposed as an important factor that may enable grasses to adapt to water stress and variable climate conditions. There are many studies focusing on the stomatal morphology and development in the eudicot model plant Arabidopsis and monocot model plant Brachypodium. However, the comprehensive understanding of the distinction of stomatal structure and development between monocots and eudicots, especially between grasses and eudicots, are still less known at evolutionary and comparative genetic levels. Therefore, we employed the newly released version of the One Thousand Plant Transcriptome (OneKP) database and existing databases of green plant genome assemblies to explore the evolution of gene families that contributed to the formation of the unique structure and development of grass stomata. This review emphasizes the differential stomatal morphology, developmental mechanisms, and guard cell signaling in monocots and eudicots. We provide a summary of useful molecular evidences for the high water use efficiency of grass stomata that may offer new horizons for future success in breeding climate resilient crops.
