(Submitter supplied) To further investigate the gene expression profiles in agb1 mutant seedlings responding to salt stress, we employed whole transcriptome microarray expression profiling as a discovery platform to identify genes with the potential to be regulated by AGB1-mediated signaling cascades. Arabidopsis thaliana 7-day-old wild-type and agb1-3 mutant roots were challenged by immersing in 150 mM NaCl containing MS liquid media for 0 or 4 hours, and 4,830 genes induced by high salinity were identified that distinguished between zero and four hours among wild-type and agb1-3 samples. more...

(Submitter supplied) Transcriptional profiling of Arabidopsis thaliana 12-days old seedlings comparing Col-0 wild type with transgenic plants with altered expression of dual-targetting plastid/mitochondrial organellar RNA-polymerase RPOTmp. Transgenic plants used for experiment were: overexpressor plants obtained by transformation of Col-0 WT plants with genetic constructs created in [Tarasenko et al., 2016] contained catalytic part of RPOTmp enzyme with transit peptides of RPOTm (mitochondrial) and RPOTp (plastid) by agrobacterial transformation; plants with complementation of RPOTmp functions in mitochondria or chloroplasts obtained from transformation of GABI_286E07 rpotmp knockout-mutant plants with genetic constructs created in [Tarasenko et al., 2016]. more...

(Submitter supplied) To cope with limiting phosphorus (P) availability, plants have evolved a series of mechanisms to recycle internal P sources and to acquire P from the soil. One of these mechanisms is the release of low-molecular weight carboxylates, such as malate, which helps to liberate phosphate desorbed to aluminum and iron oxides. As malate release into the rhizosphere and root apopplast also increases iron availability. more...

(Submitter supplied) To optimize access to nitrogen under limiting conditions, root systems must continuously sense and respond to local or temporal fluctuations in nitrogen availability. In Arabidopsis thaliana and several other species, external N levels that induce only mild deficiency stimulate the emergence of lateral roots and especially the elongation of primary and lateral roots. However, the identity of the genes involved in this coordination remains still largely elusive. more...

(Submitter supplied) We report that phosphatidylglycerol (PG) biosynthesis in plastid is required for plastid gene expression mediated by plastid-encoded RNA polymerase and light-induced expression of nuclear-encoded photosynthesis-associated genes. A transcription factor GOLDEN-LIKE1 was also found to be involved in the downregulation of nuclear photosynthesis genes in responce to PG deficiency.

(Submitter supplied) To analyze the extent of the overlap between MeJA-induced transcripts and MeJA- induced histone acetylation, the expression profiles of WT untreated (WT), WT+MeJA, axe1-5 untreated and axe1-5+MeJA samples were analysed using the catalog microarray (Agilent design ID:21169). Whole A. thaliana seedlings of axe1-5 mutant and DR5 wild-type lines (Murfett et al 2001) were grown in vitro for 12 days on 1% Murashige and Skoog (MS) medium (Duchefa) supplemented with 1% sucrose, 0.8% phytoagar (Duchefa) and buffered to pH 5.8. more...

(Submitter supplied) Wounding triggers de novo organogenesis, vascular reconnection and defense response but how wound stress evokes such a diverse array of physiological responses remains unknown. We previously identified an AP2/ERF transcription factor, WOUND INDUCED DEDIFFERENTIATION1 (WIND1), as a key regulator of wound-induced cellular reprogramming in Arabidopsis. To understand how WIND1 promotes downstream events, we performed time-course transcriptome analyses after WIND1 induction. more...

In order to characterize the early and later gene expression of Arabidopsis thaliana after a mono-rhamnolipid treatment, ten-day-old Col-0 Arabidopsis seedlings were treated by root absorption with 100µM of mono-rhamnolipids (in 0.5% EtOH) or water (0.5% EtOH) and harvested after 1 or 3 hours. RNA samples were labelled, hybridized to Agilent Arabidopsis microarrays, washed, scanned and data acquired. more...
