In rice, currently ~240 miRNAs have been annotated. We sequenced more than four million small RNAs from rice and identified another 24 miRNA genes. Among these, we found a novel class of miRNAs that derive from natural cis-antisense transcript pairs. This configuration generates miRNAs that can perfectly match their targets. We provide evidence that the miRNAs function by inducing mRNA cleavage in the middle of their complementary site. Their production requires DCL1 activity, which is essential for canonical miRNA biogenesis. All of the nat-miRNAs identified in this study have large introns in their precursors that appear critical for nat-miRNA evolution and for the formation of functional miRNA loci. These findings suggest that other natural cis-antisense loci with similar exon-intron arrangements could be another source of miRNA genes"'

GSE10872_series_matrix.txtimp_info.txt	Found 'mutant' in '!Series_summary	"  SA0420 is a stable rice (Oryza sativa L.) mutant exhibits multiple traits including a leaf-tip yellowing (YLT), a taro fragrance (or aroma, A), a reduced panicle number (PN), spikelet number (SN), plant height (PH), days to heading (DH), filled grain weight (FGW), and fertility rate (FR), different from those of a local cultivar TNG67. Correlation analysis on F2 progenies of SA0420 and TNG67 revealed that except for aroma which is inheritated independently, phenotypes including YLT, PN, SN, PH, and FGW are tightly associated with each others, indicating a control simultaneously by pleotropic gene. Among those phenotypes, YLT appears the earliest at vegetative stage, therefore may act as a predisposing factor that give rise to other phenotypes. Genetic analysis suggested that YLT is controlled by a single recessive gene. By analyzing the recombinant inbreed lines (RILs) that produce YLT and normal green (G) progenies in a 1:3 ratio, the phenotypes associated with YLT were further confirmed. To investigate the molecular events of leaf-tip yellowing, microarray analyses were performed to compare the gene expression profiles between YLT and G plants of RILs. Clustering of genes according to their involved metabolic pathways revealed that various photosynthesis and carbon fixation gene expressions are lower (~55~75%) in YLT than in G plants, consistent with the observation that photosynthesis rate of SA0420 was only 60% to that of TNG67. Moreover, higher expressions of oxidative phosphorylation-related genes indicated that not only the reduced synthesis rate but also the elevated energy consumptions may synergistically decrease the growth vigor of SA0420. Dissection of the mature leaf revealed that chlorophyll is drastically reduced in the leaf-tip of SA0420 while carotenoids remain stable. This explains the appearance of leaf-tip yellowing and recall an analogy of early senescence. Indeed, many senescence-associated genes (SAG) were found to be up-regulated in SA0420."'
GSE11021_series_matrix.txtimp_info.txt	Found 'inhibition' in '!Series_summary	"Gene expression in response to Cu stress in rice leaves was quantified using DNA microarray (Agilent 22K Rice Oligo Microarray) and real-time PCR technology. Rice plants were grown in hydroponic solutions containing 0.3 (control), 10, 45 or 130 µM of CuCl2, and Cu accumulation and photosynthesis inhibition were observed in leaves within 1 day of the start of treatment. Microarray analysis flagged 305 Cu-responsive genes, and their expression profile showed that a large proportion of general and defense stress response genes are up-regulated under excess Cu conditions, whereas photosynthesis and transport-related genes are down-regulated. The Cu sensitivity of each Cu-responsive gene was estimated by the median effective concentration value (EC50) and the range of fold-changes (F) under the highest (130 µM) Cu conditions (|log2F|130). Defense-related genes involved in phytoalexin and lignin biosynthesis were the most sensitive to Cu. Our results indicate that plant management of abiotic and pathogen stresses has overlapping components, possibly including signal transduction. "'

The understanding of plant responses to stresses in physiology, genetics, and molecular biology will be greatly helpful to improve the tolerance of crops to abiotic-stresses through genetic engineering.To identify the genetic loci that control drought and salt tolerance in rice, we performed a large-scale screen for the mutants with altered drought and salt tolerance. A drought and salt tolerance (dst) mutant line was isolated.In this series, we compare the transcriptome of wild-type plant Zhonghua11 and dst mutants under the normal growth conditions."'

We found that the improvement of a plant variety through the acquisition of a new desired trait, using either mutagenesis or transgenesis, may cause stress and thus lead to an altered expression of untargeted genes. In all of the cases studied, the observed alteration was more extensive in mutagenized than in transgenic plants. We propose that the safety assessment of improved plant varieties should be carried out on a case-by-case basis and not simply restricted to foods obtained through genetic engineering."'
