Summary of "Guard Cell Metabolism and Stomatal Function."

The control of gaseous exchange between the leaf and external atmosphere is governed by stomatal conductance (); therefore, stomata play a critical role in photosynthesis and transpiration and overall plant productivity. Stomatal conductance is determined by both anatomical features and behavioral characteristics. Here we review some of the osmoregulatory pathways in guard cell metabolism, genes and signals that determine stomatal function and patterning, and the recent work that explores coordination between and carbon assimilation () and the influence of spatial distribution of functional stomata on underlying mesophyll anatomy. We also evaluate the current literature on mesophyll-driven signals that may coordinate stomatal behavior with mesophyll carbon assimilation and explore stomatal kinetics as a possible target to improve and water use efficiency. By understanding these processes, we can start to provide insight into manipulation of these regulatory pathways to improve stomatal behavior and identify novel unexploited targets for altering stomatal behavior and improving crop plant productivity. Expected final online publication date for the , Volume 71 is April 29, 2020. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

ABA-triggered guard cell -cysteine desulfhydrase function and in situ H S production contributes to heme oxygenase-modulated stomatal closure.

Recent studies have demonstrated that hydrogen sulfide (H S) produced through the activity of -cysteine desulfhydrase (DES1) is an important gaseous signaling molecule in plants that could participat...

Myrosinases, TGG1 and TGG2, redundantly function in reactive carbonyl species signaling in Arabidopsis guard cells.

Myrosinase (thioglucoside glucohydrolase, EC 3.2.1.147, TGG) is a highly abundant protein in Arabidopsis guard cells and TGG1 and TGG2 redundantly function in abscisic acid (ABA)- and methyl jasmonate...

Callose and homogalacturonan epitope distribution in stomatal complexes of Zea mays and Vigna sinensis.

This article deals with the distribution of callose and of the homogalacturonan (HG) epitopes recognized by LM20, JIM5, and 2F4 antibodies in cell walls of differentiating and functioning stomatal com...

BZU2/ZmMUTE controls symmetrical division of guard mother cell and specifies neighbor cell fate in maize.

Intercellular communication in adjacent cell layers determines cell fate and polarity, thus orchestrating tissue specification and differentiation. Here we use the maize stomatal apparatus as a model ...

RPK1 and BAK1 sequentially form complexes with OST1 to regulate ABA-induced stomatal closure.

Regulation of plant water status occurs via abscisic acid (ABA)-induced stomatal closure. Open Stomata 1 (OST1) is a critical ABA signaling component regulating this process in guard cells. We previou...

Medical and Biotech [MESH] Definitions

A secreted angiopoietin-like protein expressed under hypoxic conditions by ENDOTHELIAL CELLS. It inhibits cell proliferation, cell migration, and tubule formation; the inactive form accumulates in the endothelial EXTRACELLULAR MATRIX, reducing vascular leakage. ANGPTL4 has direct roles in regulating glucose and lipid metabolism, as well as INSULIN SENSITIVITY, and may also function as a regulator of angiogenesis and tumorigenesis.

The major metabolite in neutrophil polymorphonuclear leukocytes. It stimulates polymorphonuclear cell function (degranulation, formation of oxygen-centered free radicals, arachidonic acid release, and metabolism). (From Dictionary of Prostaglandins and Related Compounds, 1990)

A glycogen synthase kinase that was originally described as a key enzyme involved in glycogen metabolism. It regulates a diverse array of functions such as CELL DIVISION, microtubule function and APOPTOSIS.

A family of large terrestrial carnivores possessing long legs, coarse guard hairs and a busy tail. It is comprised of hyenas and aardwolves.

Blue-light receptors that regulate a range of physiological responses in PLANTS. Examples include: PHOTOTROPISM, light-induced stomatal opening, and CHLOROPLAST movements in response to changes in light intensity.
