(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) The Atss3 mutant and WT plants were arranged according to a Randomized Complete Block Design. The plants were planted in rows with seven rows in each flat; two plants of the same genotype/pot. Plants were grown under a SD photoperiod (8 h light/16 h dark) in a growth chamber as described. Eight randomly selected rows were harvested for each time point from different flats. Plant material was harvested at five time points in the diurnal cycle (1, 4, 8.5, 12, and 16 h; Time 0 is the beginning of the light period); harvesting was conducted under a green safety light. more...

(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) The goal of this experiment was to explore the extent of KIN10 (At3g01090) transcriptional regulation and identify its early target genes in Arabidopsis mesophyll protoplasts. Results suggest that KIN10 targets a remarkably broad array of genes that orchestrate transcription networks, promote catabolism and autophagy, and suppress anabolism and ribosome biogenesis. The transient expression condition ruled out secondary or long-term effects of metabolism and growth, and circumvented experimental limitations caused by redundancy and embryonic lethality observed in mammals and plants. more...

(Submitter supplied) The goal of this experiment was to investigate the early transcript changes (6h) induced by hypoxia treatment in mesophyll protoplasts. A single pair (control & hypoxia) of GeneChips® was used to confirm that hypoxia treatment altered the expression of an overlapping set of genes controlled by KIN10 (At3g01090) in Arabidopsis mesophyll protoplasts.
