TranscriptomicsExpression analysis of the response to wild-type and pye-1 mutants to iron sufficient or iron deficient conditions
Transcriptional profile of whole roots of wild-type and pye-1 mutants exposed to 24 hours -Fe were generated Global population increases and climate change underscore the need for better comprehension of how plants acquire and process nutrients such as iron. A systems biology approach was taken to e...

TranscriptomicsExpression analysis of root cell types after treatment with sulfur deficient media
Cell-type specific transcriptional profiles were generated by FACS (Fluorescence Activated Cell Sorting) sorting of roots that express cell-type specific GFP-reporters. Five different GFP-reporter lines were used. FACS cell populations were isolated from roots grown under sulfur deficient conditions...

TranscriptomicsExpression analysis of the effect of protoplasting and sorting in roots exposed to low pH
To estimate the effect of protoplasting and sorting on low pH-regulated gene expression, we generated expression profiles for whole roots treated with low pH for 24 hours and whole roots that had been protoplasted and FACS sorted after 24 hours of exposure to low pH. Stress responses in plants are t...

TranscriptomicsExpression analysis of root cell types after treatment with low pH
Cell-type specific transcriptional profiles were generated by FACS (Fluorescence Activated Cell Sorting) sorting of roots that express cell-type specific GFP-reporters. Five different GFP-reporter lines were used. FACS cell populations were isolated from roots grown under standard pH (pH 5.7) or roo...

TranscriptomicsExpression analysis of developmental stages of Arabidopsis roots exposed to low pH
To understand the effect of low pH on developmental stages in the root, we dissected the root into four developmental zones after exposure to low pH and expression profiled each zone. Stress responses in plants are tightly coordinated with developmental processes, but the interaction between these p...

TranscriptomicsExpression analysis time-course of Arabidopsis roots to sulfur deficiency
We preformed at time-course of the expression of whole Arabidopsis roots for 3H, 12H, 24H, 48H and 72H after transfer to media lacking sulfur. We combined these data with 13 other datasests and performed a meta-analysis to ask whether a universal stress response exists in Arabidopsis roots. Stress r...

TranscriptomicsTime-course expression analysis of the low pH (pH 4.6) response in Arabidopsis whole roots
We preformed at time-course of the expression of whole Arabidopsis roots for 30 minutes, 1H, 3H, 6H 12H, 24H, and 48H after transfer to low pH (pH 4.6). Controls at the standard pH (pH 5.7) were included at each time-point. We combined these data with 13 other datasests and performed a meta-analysis...

TranscriptomicsCell signalling by microRNA165/6 directs gene dose dependent root cell fate
A key question in developmental biology is how cells exchange positional information for proper patterning during organ development. In plant roots the radial tissue organization is highly conserved with a central vascular cylinder in which two water conducting cell types, protoxylem and metaxylem, ...
