(Submitter supplied) Drought and salt stress severely inhibit plant growth and development. However, the regulatory mechanisms of plants in response to these stresses are not fully understood. Here we find that the expression of a WRKY transcription factor WRKY46 is rapidly induced by drought, salt and oxidative stresses. Mutations of WRKY46 by T-DNA insertion lead to more sensitive to drought and salt stress, whereas, overexpression of WRKY46 exhibits hypersensitive in soil culture with higher water loss rate, but increased tolerance on the agar plates. more...

(Submitter supplied) To explore the possible cause for the enhanced tolerance to osmotic stress exhibited by wrky54wrky70 double mutant, we have used Agilent Arabidopsis (V4) Gene Expression Microarray to characterize the effect of these mutations under the osmotic stress treatment. In addition to wild type and wrky54wrky70 double mutant, sid2-1 single and wrky54wrky70sid2-1 triple mutant were also included in the microarray experiment. more...

(Submitter supplied) In plants, drought stress is a major growth limiting factor causing cell water loss through open stomata. In this study, guard cell-specific transcripts from drought-stressed Arabidopsis plants were analyzed and a down-regulation of β-amylase 1 (BAM1) was found. In previous studies, BAM1 was shown to be involved in stomatal starch degradation under ambient conditions. Impaired starch breakdown of bam1 mutant plants was accompanied by decreased stomatal opening. more...

(Submitter supplied) To understand the role of the Arabidopsis type-B Response Regulators ARR1, ARR10 and ARR12 in water stress response, we have carried out comparative expression analysis of the arr1,10,12 mutant and WT plants under dehydration and well-watered (control) conditions. Agilent’s whole Arabidopsis Gene Expression Microarray (G2519F-021169, V4, 4x44K) was used.

(Submitter supplied) Stomata pores are surrounded by a pair of guard cells in the epidermis in plants. Stomata apature is controlled by environmental factors. Stomata opening is also enhanced by introduction of SOC1-GFP driven by GC1 promoter in phot1 phot2 double mutants (pGC1::SOC1-GFP/ phot1 phot2). Epidermis including guard cells were isolated from phot1 phot2 and pGC1::SOC1-GFP/phot1 phot2 and gene expression were analyzed.

Inactivation of RRTF1 restricts and overexpression promotes reactive oxygen species (ROS) accumulation in response to stress. Overexpressor (oe) lines are impaired in root and shoot development, light sensitive and susceptible to Alternaria brassicae infection. more...

(Submitter supplied) Leaf growth is a complex developmental process that is continuously fine-tuned by the environment. Various abiotic stresses, including mild drought stress, have been shown to inhibit leaf growth in Arabidopsis thaliana (Arabidopsis), but the underlying mechanisms remain largely unknown. Here we identify the redundant Arabidopsis transcription factors ETHYLENE RESPONSE FACTOR 5 (ERF5) and ERF6 as master regulators which adapt leaf growth to environmental changes. more...

(Submitter supplied) To understand how plants respond to anoxia-reoxygenation, we have employed a global microarray expression profiling as a basic platform to characterize genes with the potential to mediate the recovery responses in Arabidopsis. 7-day-old seedlings were trated with 4hr and 8hr anoxia, and then reoxygenated in air for 0, 0.5, 1, 3, 6 hrs. Genes changed in both condition were designated as reoxygenation-regulated genes. more...

(Submitter supplied) Endosomal trafficking plays integral roles in various eukaryotic cell activities. In animal cells, a member of the RAB GTPase family, RAB5, is a key regulator of various endosomal functions. In addition to orthologs of animal RAB5, plants harbor the plant-specific RAB5 group, the ARA6 group, which is conserved in land plant lineages. In Arabidopsis thaliana, ARA6 and conventional RAB5 act in distinct endosomal trafficking pathways; ARA6 mediates trafficking from endosomes to the plasma membrane, whereas conventional RAB5 acts in endocytic and vacuolar trafficking pathways. more...

(Submitter supplied) Stomata are highly specialized organs which consist of pairs of guard cells and regulate gas and water vapor exchange in plants. While early stages of guard cell differentiation have been described and were interpreted in analogy to processes of cell type differentiation in animals, the downstream development of functional stomatal guard cells remains poorly understood. We have isolated an Arabidopsis mutant, scap1 (stomatal carpenter 1), that develops irregularly shaped guard cells and lacks the ability to control stomatal aperture, including CO2-induced stomatal closing and light-induced stomatal opening. more...

(Submitter supplied) Regulation of stomatal movement is one of the effective strategies for developing resistant crops to air pollutant because stomata allows absorption of various air pollutants, such as ozone and sulfur dioxide. Transcription factor (TF) is a fascinating target of genetic manipulation for this end because TF regulates many genes simultaneously and methods of genetic manipulation are universally established. more...

As multifaceted molecule, ROS are known to accumulate in response to various stresses, and ROS burst accompanied with transcriptomic reprogramming leading to defense response or programmed cell death. Acute ozone exposure has been used as a noninvasive tool to study ROS burst induced defense response and cell death for a long time. more...

(Submitter supplied) A better understanding of the mechanisms for plant in response to abiotic stresses is key for the improvement of plant to resistant to the stresses. Much has been known for the regulation of gene expression in response to salt stress at transcriptional level, however, little is known at posttranscriptional level for this response. Recently, we identified that SKIP is a component of spliceosome and is necessary for the regulation of alternative splicing and mRNA maturation of clock genes. more...
