Small RNA from Arabidopsis thaliana with RNA silencing directed to Chalcone Synthase (At5G13930) by a hairpin RNA, a 21-nt artificial miRNA and a 22-nt artificial miRNA in the pap1-D over-expressing background

Project description:22-nucleotide (nt) microRNAs (miRNAs) derived from asymmetric duplexes trigger trans-acting phased small interfering RNA (tphasiRNA) production from complementary targets. Here we investigate the efficacy of 22-nt artificial miRNA (amiRNA) mediated RNA silencing relative to conventional hairpin RNA (hpRNA) and 21-nt amiRNA mediated RNA silencing. CHALCONE SYNTHASE (CHS) was selected as a target in Arabidopsis thaliana due to the obvious and non-lethal loss of anthocyanin accumulation upon widespread RNA silencing. Over-expression of CHS in the pap1-D background facilitated visual detection of both local and systemic RNA silencing. RNA silencing was initiated in leaf tissues from hpRNA and amiRNA plant expression vectors under the control of an Arabidopsis RuBisCo small subunit 1A promoter (SSU). In this system, hpRNA expression triggered CHS silencing in most leaf tissues but not in roots or seed coats. Similarly, 21-nt amiRNA expression from symmetric miRNA/miRNA* duplexes triggered CHS silencing in all leaf tissues but not in roots or seed coats. However, 22-nt amiRNA expression from an asymmetric duplex triggered CHS silencing in all tissues, including roots and seed coats, in the majority of plant lines. This widespread CHS silencing required RNA DEPENDENT RNA POLYMERASE6 mediated accumulation of phasiRNAs from the endogenous CHS transcript. These results demonstrate the efficacy of asymmetric 22-nt amiRNA-directed RNA silencing and associated phasiRNA production and activity, in mediating widespread RNA silencing of an endogenous target gene. Asymmetric 22-nt amiRNA directed RNA silencing requires little modification of existing amiRNA technology and is expected to be effective in suppressing other genes and/or members of gene families. sRNA sequencing from aerial tissues of 3-week old plants grown on MS media

iTRAQ analyses of Fe-sufficient and Fe-deficient non-transformant and HRZ-knockdown rice roots

Project description:We conducted iTRAQ analyses using soluble proteins extracted from roots of non-transformant rice (NT) and previously generated HRZ-knockdown (HRZi) lines (Kobayashi et al., 2013 Nat Commun 4: 2792) cultivated under Fe-sufficient and Fe-deficient conditions. We identified and quantified 3,033 and 3,525 proteins in replicate 1 and 2, respectively, which totaled 4,884 proteins including 1,698 overlapping proteins between the two replicate experiments.

During development, the Sku5 mutant roots engage different genes than wild type WS roots, either on the ground or in spaceflight.

Project description:The wild type WS plants and the Sku5 mutant plants in the WS background were germinated on ISS or on the ground and the gene expression profiles in roots at 4 days or 8 days were established. The Sku5 gene (AT4G12420) codes for a multi-copper oxidase-like protein SKU5 protein that is involved in directed root tip growth. The Sku5 protein is glycosylated, GPI-anchored and localizes to the plasma membrane and the cell wall. The Sku5 gene is expressed most strongly in expanding tissues. The development of WS and Sku5 plants on orbit differs from that on the ground as demonstrated by the comparison of the gene expression profiles between 4 days old to 8 days old plant in the two environments. However the development of Sku5 mutant plants also differs from WS at either age and in either environment, suggesting the role of the genetic background in these developmental decisions. The 4 days old Sku5 roots in orbit engaged substantially more genes than the 4 days old WS roots in orbit but also more than the 4 days old Sku5 roots on the ground. Overall the 4 days old roots differentially expressed more genes in spaceflight relative to ground than the 8 days old roots of either genotype. Finally, the 4 days old Sku5 roots in orbit differ in 862 genes from the 8 days Sku5 roots in orbit while on the ground there is merely half of the number of genes differentially expressed between the 4 days and 8 days developmental stages of the Sku5 roots.

During development, the Sku6 mutant roots engage different genes than wild type Col-0 roots, either on the ground or in spaceflight.

Project description:The wild type Col-0 plants and the Sku-6 mutant plants of the Col-0 background were germinated on ISS or on the ground and the gene expression profiles in roots at 4 days or 8 days were established. The Sku6 gene (At2g03680) codes for a protein that localizes to microtubule within the cortical array and putatively acting as an intramolecular linker. The development of Col-0 and Sku-6 plants on orbit differs from that on the ground as demonstrated by the comparison of the gene expression profiles between 4 days old to 8 days old plant in the two environments. However the development of Sku-6 mutant plants also differs from Col-0 at either age and in either environment, suggesting the role of the genetic background in these developmental decisions. The 4 days old Sku-6 roots in orbit engaged more genes than the 4 days old Col-0 roots in orbit but also more than the 4 days old Sku-6 roots on the ground. Overall the 4 days old roots differentially expressed more genes in spaceflight relative to ground than the 8 days old roots of either genotype.
