Abstract:
Preserving crop yield under drought stress is a major challenge
for modern agriculture. To cope with the detrimental effects of
water scarcity on crop productivity it is important to develop
new plants with a more sustainable use of water and capable
of higher performance under stress conditions. Transpiration
through stomatal pores accounts for over 90% of water loss in land
plants. Recent studies have increased our understanding of the
networks that control stomatal activity and have led to practical
approaches for enhancing drought tolerance. Genetic engineering
of target genes in stomata requires effective expression systems,
including suitable promoters, because constitutive promoters (i.e.,
CaMV35S) are not always functional or can have negative effects
on plant growth and productivity. Here we describe the identification
of the CYP86A2 guard cell promoter and discuss its potential
for gene expression in stomata.
