“…We observed the downregulation of PTF1 in shoot at early ++P stress. Overexpression of this gene however, could enhance tolerance to -P in transgenic rice (Yi et al 2005). Among histone genes, ++P stress induced the upregulation of histone-like transcription factor (Os03t0413000) Fig.…”

Plants have developed several morphological and physiological strategies to adapt to phosphate stress. We analyzed the inducible transcripts associated with phosphate starvation and over-abundant phosphate supply to characterize the transcriptome in rice seedlings using the mRNA-Seq strategy. Fifty-three million reads obtained from 16 libraries under various phosphate stress and recovery treatments were uniquely mapped to the rice genome. Transcripts identified specifically tagged to 40,574 (root) and 39,748 (shoot) Rice Annotation Project (RAP) transcripts. Additionally, we detected uniquely 10,388 transcripts with no match to any RAP transcript. These transcripts that showed specific response to Pi stress include those without ORFs that may act as non-protein coding transcripts. With an accompanying browser of the transcriptome under Pi stress, a deeper understanding of the structural and functional features of both annotated and unannotated Pi stress-responsive transcripts can provide useful information in improving Pi acquisition and utilization in rice and other cereal crops.

“…Some transcription factors have specifically been associated with the response to P deprivation. They include OsPTF1 (Os06g09370), which has been reported to contribute to tolerance to inorganic phosphate starvation (Yi et al 2005), the "phosphate-induced protein" (phi-1; Os02g52040), and the "phosphate starvation response" factors (PHR1, Os03g21240; PHR2, Os07g25710) that form a regulatory circuit with PHO2 (Os06g40500) and micro-RNA399 (Fang et al 2008;Bari et al 2006). All were only regulated by the factor E and only in shoots.…”

Transcriptional profiling has identified genes associated with adaptive responses to phosphorus (P) deficiency; however, distinguishing stress response from tolerance has been difficult. We report gene expression patterns in two rice genotypes (Nipponbare and NIL6-4 which carries a major QTL for P deficiency tolerance (Pup1)) grown in soil with/without P fertilizer. We tested the hypotheses that tolerance of NIL6-4 is associated with (1) internal P remobilization/redistribution; (2) enhanced P solubilization and/or acquisition; and (3) root growth modifications that maximize P interception. Genes responding to P supply far exceeded those differing between genotypes. Genes associated with internal P remobilization/ redistribution and soil P solubilization/uptake were stress responsive but often more so in intolerant Nipponbare. However, genes putatively associated with root cell wall loosening and root hair extension (xyloglucan endotransglycosylases/hydrolases and NAD(P)H-dependent oxidoreductase) showed higher expression in roots of tolerant NIL6-4. This was supported by phenotypic data showing higher root biomass and hair length in NIL6-4.

“…Several genes are important for stress responses, including OsbHLH1 (i.e. OsbHLH062 in this study) in cold response , OsPTF1(OsbHLH096) in tolerance to phosphate starvation (Yi et al, 2005), and RERJ1 (OsbHLH006) in wound and drought responses (Kiribuchi et al, 2004(Kiribuchi et al, , 2005. Also, OsBP-5 (OsbHLH102) is involved in transcriptional regulation of the rice Wx gene (Zhu et al, 2003), and Ra (OsbHLH013) and Rb (OsbHLH165; Hu et al, 1996) are homologs of the maize (Zea maize) Lc gene; OsMYC (OsbHLH009; Zhu et al, 2005) is a homolog of AtMYC2.…”

Genome-Wide Analysis of Basic/Helix-Loop-Helix Transcription Factor Family in Rice and Arabidopsis

The basic/helix-loop-helix (bHLH) transcription factors and their homologs form a large family in plant and animal genomes. They are known to play important roles in the specification of tissue types in animals. On the other hand, few plant bHLH proteins have been studied functionally. Recent completion of whole genome sequences of model plants Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa) allows genome-wide analysis and comparison of the bHLH family in flowering plants. We have identified 167 bHLH genes in the rice genome, and their phylogenetic analysis indicates that they form well-supported clades, which are defined as subfamilies. In addition, sequence analysis of potential DNA-binding activity, the sequence motifs outside the bHLH domain, and the conservation of intron/exon structural patterns further support the evolutionary relationships among these proteins. The genome distribution of rice bHLH genes strongly supports the hypothesis that genome-wide and tandem duplication contributed to the expansion of the bHLH gene family, consistent with the birth-and-death theory of gene family evolution. Bioinformatics analysis suggests that rice bHLH proteins can potentially participate in a variety of combinatorial interactions, endowing them with the capacity to regulate a multitude of transcriptional programs. In addition, similar expression patterns suggest functional conservation between some rice bHLH genes and their close Arabidopsis homologs.
