(Submitter supplied) We characterized the biological and molecular functions of AtC3H17, a unique Arabidopsis gene encoding a non-tandem CCCH zinc finger protein, in plant development. To investigate the downstream regulatory mechanisms of AtC3H17, whole genome microarray expression profiling was carried out. The experiment was designed to identify differentially expressed genes between WT and AtC3H17-overexpressing transgenic plants (AtC3H17 OXs) grown for 14 days under SD growth conditions. more...

(Submitter supplied) Plant-specific DOF-type transcription factors regulate various biological processes. Here, we characterized a silique-abundant gene AtDOF4.2 for its functions in Arabidopsis. AtDOF4.2 is localized in the nuclear region and has transcriptional activation activity in both yeast and plant protoplast assays. The Thr-Met-Asp motif in AtDOF4.2 is essential for its activation. AtDOF4.2-overexpressing plants exhibit an increased branching phenotype, and the mutation of Thr-Met-Asp motif in AtDOF4.2 significantly reduces the branching in transgenic plants. more...

(Submitter supplied) Phytohormones play crucial roles in regulating many aspects of plant development. Although much has been learned about the effects of individual hormones, cross-talk between and integration of different hormonal signals are still not well understood. We present a study of MINI ZINC FINGER 1 (MIF1), a putative zinc finger protein from Arabidopsis, and suggest that it may be involved in integrating signals from multiple hormones. more...

(Submitter supplied) In addition to the evolutionarily-conserved Ca2+ sensor, calmodulin (CaM), plants possess a large family of CaM-related proteins (CMLs). Using a cml39 loss-of-function mutant, we investigated the roles of CML39 in Arabidopsis and discovered a range of phenotypes across developmental stages and in different tissues. In mature plants, loss of CML39 results in shorter siliques, reduced seed number per silique, and reduced number of ovules per pistil. more...

(Submitter supplied) Integration of environmental signals and interactions among photoreceptors and transcriptional regulators is key in shaping plant development. TANDEM ZINC-FINGER PLUS3 (TZP) is an integrator of light and photoperiodic signaling that promotes flowering in Arabidopsis thaliana. Here we elucidate the molecular role of TZP as a positive regulator of hypocotyl elongation. We identify an interacting partner for TZP, the transcription factor ZINC-FINGER HOMEODOMAIN 10 (ZFHD10), and characterize its function in coregulating the expression of blue-light dependent transcriptional regulators and growth-promoting genes. more...

(Submitter supplied) Recently, AtC3H14, a CCCH-type zinc finger protein, was identified as one of the direct targets of MYB46, which is known as a master regulator of secondary wall biosynthesis. AtC3H14 and their homologs (i.e., AtC3H15 and PtrC3H14-1 from Arabidopsis and poplar, respectively) are predominantly expressed in the secondary wall forming tissues. Transgenic Arabidopsis plants overexpressing AtC3H14 (i.e., 35S::AtC3H14 plants) produced dwarfing phenotypes. more...

(Submitter supplied) Keeping imbibed seeds at low temperatures for a certain period, so called seed vernalization (SV) treatment, promotes seed germination and subsequent flowering in various plants. Vernalization-promoting flowering requires GSH. However, the expression patterns analyzed by GeneChip arrays showed that increased GSH biosynthesis partially mimics SV treatment in Arabidopsis thaliana. SV treatment (keeping imbibed seeds at 4°C for 24 h) induced a specific pattern of gene expression and promoted subsequent flowering in wild-type plants. more...

(Submitter supplied) Transcriptional profiling of Arabidopsis far-red light pulse treated seeds comparing luh mutant with wild type (Col-0). Seeds were imbibed within 1 hr under white light and treated far-red light pulse for 5 min followed by 12 hr dark incubation. Goal was to determine the effects of LUH as transcriptional co-regulator during seed germination process.

(Submitter supplied) Nuclear-localized RNA binding proteins are involved in various aspects of RNA metabolism, which in turn modulates gene expression. However, the functions of nuclear-localized RNA binding proteins in plants are poorly understood. Here we report the functions of two proteins containing RNA recognition motifs, At RZ-1B and At RZ-1C, in Arabidopsis. At RZ-1B and At RZ-1C were localized to nuclear speckles and interacted with a spectrum of serine/arginine-rich (SR) proteins through their C-termini. more...

(Submitter supplied) R1R2R3-Myb proteins represent an evolutionarily conserved class of Myb family proteins important for cell cycle regulation and differentiation in eukaryotic cells. In plants, this class of Myb proteins are believed to play important roles in cell cycle regulation through transcriptional regulation of G2/M phase-specific genes by binding to common cis-elements, called MSA elements. In Arabidopsis thaliana, MYB3R1 and MYB3R4 act as transcriptional activators and positively regulate cytokinesis by activating transcription of KNOLLE, which encodes a cytokinesis-specific syntaxin. more...

(Submitter supplied) Global gene expression was compared between Arabidopsis lines with altered expression of ANAC102 (over-expressed and knocked-out) and wild-type. ANAC102 is a putative NAC domain transcription factor. Gene expression was compared between an ANAC102 over-expressing line and parental ecotype C24 under ambient atmosphere to determine which genes ANAC102 is capable of regulating. Gene expression was also compared between three week old plants of an ANAC102 knock-out line and parental ecotype Col-0 under 0.1% Oxygen and ambient atmosphere conditions to determine which genes may require ANAC102 for appropriate expression under these conditions. more...

(Submitter supplied) Expression profiling of two-weeks-old wild type, nar1-4/- and nbp35-3/- mutant seedlings. The cytosolic Fe -S cluster assembly pathway is involved in cytosolic and nucleus Fe-S protein maturation. The nar1 mutant was identified by the screeing for abnormal transcription feature in endosperm.We performed genome-wide transcriptional profiling of weak allele nar1-4/- using microarrays to estimate whether the cytosolic Fe -S cluster assembly could affect on the transcriptional profile even in vegetative tissues.
