Effects of lithium on stomatal regulation.
Recent findings indicate that lithium belongs to the group of rather exclusive agents which affect the period of circadian clocks: The period of the cir cadian petal movements of Kalanchoe is increased by about 2 hours in 5 m M LiCl 2. In the present paper we will report an action of lithium on a much more rapid oscillation, which under certain circum stances occurs in stomatal regulation. Th...
متن کاملOrthologs of Arabidopsis thaliana stomatal bHLH genes and regulation of stomatal development in grasses.
Stomata are adjustable pores in the plant epidermis that regulate gas exchange between the plant and atmosphere; they are present on the aerial portions of most higher plants. Genetic pathways controlling stomatal development and distribution have been described in some detail for one dicot species, Arabidopsis, in which three paralogous bHLH transcription factors, FAMA, MUTE and SPCH, control ...
متن کاملMicroRNA-mediated regulation of stomatal development in Arabidopsis.
The proper number and distribution of stomata are essential for the efficient exchange of gases between the atmosphere and the aerial parts of plants. We show that the density and development of stomatal complexes on the epidermis of Arabidopsis thaliana leaves depend, in part, on the microRNA-mediated regulation of Agamous-like16 (AGL16), which is a member of the MADS box protein family. AGL16...
متن کاملReactive Oxygen Species in the Regulation of Stomatal Movements.
Guard cells form stomatal pores that optimize photosynthetic carbon dioxide uptake with minimal water loss. Stomatal movements are controlled by complex signaling networks that respond to environmental and endogenous signals. Regulation of stomatal aperture requires coordinated activity of reactive oxygen species (ROS)-generating enzymes, signaling proteins, and downstream executors such as ion...
متن کاملEvolution of the Stomatal Regulation of Plant Water Content[OPEN]
Terrestrial productivity today is regulated by stomatal movements, but this has only been the case since “stomatophytes” became dominant on the land 390 million years ago. In this review,we examine evidence for the functionof early stomata, foundonor near the reproductive structures of bryophyte-like fossils, and consider how this function may have changed through time as vascular plants evolve...
