Abstract Calcium (Ca 2+ ) signals are decoded by the Ca -sensor protein calmodulin (CaM) and transduced to /CaM-binding transcription factors directly regulate gene expression necessary for acclimation responses in plants. The molecular mechanisms of /CaM signal transduction processes their functional significance remains enigmatic. Here we report a novel mechanism that allosterically regulates DNA-binding activity GT2-LIKE 1 (GTL1), transrepressor STOMATAL DENSITY AND DISTRIBUTION ( SDD1 ),...
Summary We have identified a novel means to achieve substantially increased vegetative biomass and oilseed production in the model plant Arabidopsis thaliana . Endogenous isoforms of starch branching enzyme ( SBE ) were substituted by either one endosperm‐expressed maize Zea mays L.) isozymes, Zm SBEI or SBEII b. Transformants compared with starch‐free background wild‐type plants. Each maize‐derived s restored biosynthesis but both morphology structure particles altered. Altered metabolism...
The stomata on leaf surfaces control gas exchange and water loss, closing during dry periods to conserve water. distribution size of stomatal complexes is determined by epidermal cell differentiation expansion growth. Regulation these processes in response deficit may result anatomical plasticity as part the plant acclimation drought. We quantified under water-deficit conditions maize soybean over two experiments. Both species produced smaller leaves deficit, partly due reductions pavement...
Abstract The transcription factor GT2‐LIKE 1 (GTL1) has been implicated in orchestrating a transcriptional network of diverse physiological, biochemical, and developmental processes. In response to water‐limiting conditions, GTL1 is negative regulator stomatal development, but its potential rolein other water‐deficit responses unknown. We hypothesized that regulates transcriptome changes associated with drought tolerance over leaf stages. To test the hypothesis, gene expression was profiled...

Summary ⍰ Modulation of stomatal development may be an acclimation response to low water availability. However, plasticity has been assessed in very few species. We quantified leaf anatomy traits, including index (SI), density (SD), size (SS), and pore (SPI), water-deficit stress river birch ( Betula nigra L.), eastern redbud Cercis canadensis silver maple Acer saccharinum L.). Birch redbud, but not maple, had reduced SPI deficit. The mechanism by which reduction occurred (via SD or SS)...
Stomata on leaf surfaces control gas exchange and water loss, closing during dry periods to conserve water. The distribution size of guard cells is determined by the balance between epidermal cell differentiation expansion growth. Under water-deficit conditions, regulation these processes could result in stomatal anatomical plasticity as part plant acclimation drought. We investigated anatomy under deficit conditions maize soybean. In leaves, area fraction ( f gc ) was consistently reduced...
