(Submitter supplied) Phosphate is a necessary macronutrient for basic biological processes, plant growth, and agriculture. Plants modulate their root system architecture and cellular processes to adapt to phosphate deprivation albeit with a growth penalty. Excess application of phosphate in the form of fertilizer can lead to eutrophication and has negative environmental impact. Moreover, phosphate mined from rock reserves is a finite and non-recyclable resource and its levels are nearing complete depletion. more...

(Submitter supplied) Phosphorus is an essential macronutrient element, but some time causes problems if present in excess. Unlike the enormous molecular and morphophysiological information available in plants regarding phosphate (Pi) deficiency, little is known about the effect of excess Pi on plants, which is indeed essential for its remediation. Here, we have carried out a comparative study of plant molecular responses under excess Pi (20 mM) or without Pi (0 mM) at transcriptome level. more...

(Submitter supplied) Arabidopsis HMA4 transformation facilitates Zn root-to-shoot translocation, but in Zn-supply dependent manner. It implies that distinct effects of HMA4 expression on Zn root:shoot distribution in transgenics grown under different Zn supply regimes results from the interaction between the transgene activity and the molecular background of the host plant. Microarray analysis was performed to compare expression profiles in leaves of transgenic and WT-plants grown in the presence of 5 µM Zn to identify the molecular mechanism underlying the difference in Zn root:shoot distribution between 35S:AtHMA4-expressing and wild-type tomato. more...

(Submitter supplied) Ectopic expression of AtHMA4 in tomato modified Zn accumulation in a Zn-supply dependent manner. It suggests that HMA4-expression under a range of Zn-supply differentially modifies the expression of endogens, which contributes to different Zn-related phenotypes. To identify genes differentially regulated in 35S:AtHMA4-expressing and wild-type tomato, the transcription profiles were compared between roots of transgenic and WT-plants grown in the presence of 5 µM Zn. more...

(Submitter supplied) Fourteen days plants growth under hydroponic +P condition (200 μM) were treated under –P (no phosphate) condition for another 7 days, shoot of plants from 3 biological repeats were sampled for Affymetrix microarray analysis. We used microarrays to detail the global programme of gene expression underlying -Pi condition among WT and mutants of phr1, phr3 and triple mutant of phr1phr2phr3.
