Stomatal development in Arabidopsis.
Stomata consist of two guard cells around a pore and act as turgor-operated valves for gas exchange. Arabidopsis stomata develop from one or more asymmetric divisions followed by the symmetric division of the guard mother cell. Stomatal number is partly a function of the availability of smaller epidermal cells that are competent to divide asymmetrically. Stomata are spaced apart from each other...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولSCREAM/ICE1 and SCREAM2 specify three cell-state transitional steps leading to arabidopsis stomatal differentiation.
Differentiation of specialized cell types in multicellular organisms requires orchestrated actions of cell fate determinants. Stomata, valves on the plant epidermis, are formed through a series of differentiation events mediated by three closely related basic-helix-loop-helix proteins: SPEECHLESS (SPCH), MUTE, and FAMA. However, it is not known what mechanism coordinates their actions. Here, we...
متن کاملAll they know in turn
This paper studies the reasoning of non-knowledge for multiple agents. In a multi-agent environment, agents may derive knowledge from the observation that other agents do not know a fact. That means normally there does not exist a vector of maximum relations that reflect the minimum knowledge (i.e. only knowing) of all agents. In this paper, we introduce a causal relation to characterize the ap...
متن کاملCore Units of Spoken Grammar in Global ELT Textbooks
Materials evaluation studies have constantly demonstrated that there is no one fixed procedure for conducting textbook evaluation studies. Instead, the criteria must be selected according to the needs and objectives of the context in which evaluation takes place. The speaking skill as part of the communicative competence has been emphasized as an important objective in language teaching. The pr...
