ABA or GA calli treatment

ABSTRACT: The callus used for total RNA extraction was derived from the scutellum of the japonica rice variety Nipponbare and cultivated in Murashige and Skoog medium* containing 10 microM 2,4 dichlorophenoxyacetic acid. Such callus maintains the ability to develop roots and leaves. After the calli had been cultured in the medium for 30 d, they were transferred to a medium containing either ABA or GA (Gibberellin) plant hormones and cultured for 3 d. The concentration of the plant hormone was adjusted to 50 microM. After culturing, we used an RNeasy Plant Mini Kit (QIAGEN, Tokyo, Japan) to extract total RNA from the hormone-treated calli and from the controls. Messenger RNA (mRNA) was isolated with an Oligotex-dt30 (Super) mRNA purification kit (TaKaRa, Shiga, Japan). Purified mRNA was amplified, labeled, and hybridized to the NIAS RICE 22K oligonucleotide array ver1 according to the manufacturer. Keywords: other

Prematuration treatment free of 2,4-dichlorophenoxyacetic acid improves the maturation of sugarcane somatic embryos by affecting the hormonal balance and the accumulation of reserves

Project description:Several factors influence the culture conditions and somatic embryogenesis responses, such as the role of plant growth regulators (PGRs) during the establishment of in vitro cultures. For instance, auxin is required for callus induction and the acquisition of embryogenic capacity in different species, but the removal of auxin is needed for the further differentiation of somatic embryos. Thus, we aimed to evaluate the effects of residual 2,4-dichlorophenoxyacetic acid (2,4-D) on the maturation of sugarcane somatic embryos. First, embryogenic calli were separated into two groups: the PGR-free group was cultured without 2,4-D and b) the control group was maintained on proliferation culture medium, which contains 2,4-D. After 21 days of culture in the dark, both groups were transferred to maturation culture medium under light. Our results showed that calli grown in PGR-free culture medium yielded more somatic embryos and exhibited a higher accumulation of protein and starch reserves. A proteomic analysis showed a decrease in the abundance of abscisic acid (ABA)-induced proteins in the control group. The levels of residual 2,4-D and endogenous 1-aminocyclopropane-1-carboxylic acid (ACC), an ethylene precursor, were higher in the control group than in the PGR-free group. Conversely, the level of ABA was higher in the PGR-free group than in the control group. A disruption in the ABA and ethylene levels might be responsible for the observed delay in the accumulation of storage reserves in the embryogenic calli of the control group, which might have affected the development of somatic embryos. Our results also showed that the efficient development of sugarcane somatic embryos appears to be preceded by an efficient accumulation of storage reserves in calli, which is related to hormone homeostasis.

MicroRNA expression during somatic embryogenesis in Arabidopsis

Project description:The microarray test aims to find the miRNAs involved in somatic embryogenesis in Arabidopsis. The plant microRNA array V2.0 (CapitalBio Corp., Beijing, China) contained 426 non-reduplicated plant miRNA probes, including 188 in Arabidopsis. Finally, 75 plant miRNAs expressed differentially, 36 increased and 39 decreased included. Two critical period samples of somatic embryogenesis were chosen for the microarray test: the edge of embryonic calli in embryonic callus-inducing medium (ECIM) for 14 days and the secondary somatic embryos protuberances in somatic embryo-inducing medium (SEIM) for 2 days (marked as “14D” and “J2D” accordingly) . Three chip were test in each sample.

A Candidate Gene Identified in Converting Platycoside E to Platycodin D by Correlating Main Metabolites Content with Gene Expression Variation between Callus and Leaf of Platycodon grandiflorus

Project description:Platycodon grandiflorus is a perennial traditional Chinese herb, which has more than 100 compounds including triterpenoid saponins, polysaccharides and phenolic acid etc. In this study, a (L9(34)) orthogonal experiment determined the optimal explants is stem with nodes and the optimum full medium is MS + NAA 1.0 mg/L + 6-BA 0.5 mg/L as best protocol for callus induction of P. grandiflorus.The content of platycodin D, platycoside E and total polysaccharides between callus and plant organs is significantly difference, and the distribution of platycodin D, platycoside E and total polysaccharide in whole plant has been clarified. Meanwhile, the content of platycodin D and total polysaccharide were found higher in calli than in leaves or the whole plant. While, the content of platycoside E in calli is very lower than in leaves. In order to screen candidate genes involved in platycoside E and platycodin D conversion, a RNA-Seq analysis between calli and leaves was performed. Correlating the content of platycodin D and platycoside E between calli and leaves with the gene expression level involving in triterpenoid saponin biosynthesis pathway, four cluster genes with high amino acid similarity were screened as the putative sequences of β-Glucosidase gene for converting platycoside E to platycodin D. It was found that the expression level of genes encoding enzymes involved in saponins and polysaccharides biosynthesis was co-expression with the content of the corresponding metabolite. Besides, some transcription factors predicted to regulate the expression of key enzymes involving in triterpernoid saponins and polysaccharides biosynthesis pathway of P. grandiflorus.

Transcriptomic analysis of Medicago truncatula calli with MtWOX9-1 overexpression

Project description:Somatic embryogenesis (SE) is the development of embryo-like structures from somatic plant tissues. Recently, weve shown that transcription factor MtWOX9-1 belonging to WOX family is able to stimulate SE in the callus culture in Medicago truncatula. In this research, transcriptomic analysis of highly embryogenic calli with MtWOX9-1 overexpression was performed in comparison with wildtype calli. It was shown that MtWOX9-1 overexpression leads to the activation of several groups of genes, including genes related with cell division and tissue differentiation, and also with seed development. Enriched GO pathways included several groups related with histone methyltransferase activity as well as DNA methylation and chromatin binding, suggesting major epigenetic changes occuring in MtWOX9-1 overexpressing calli.

Microarray analysis of gene expression of the Arabidopsis leaf and callus

Project description:Callus formation is usually a necessary step in regenerating a new plant from detached plant tissues, and the nature of the callus is similar to that of the root meristem. In this study, we intended to address the molecular basis that directs different plant tissues to form the root-meristem-like callus. We found that leaves, but not roots, of the Polycomb group (PcG) double mutant curly leaf-50 swinger-1 lost the ability to form a callus. Using ChIP-chip analysis, we identified genes that are changed markedly in the histone H3 lysine 27 trimethylation (H3K27me3) levels during callus formation from leaf explants. Among these genes, a number of leaf-regulatory genes were repressed through PcG-mediated H3K27me3. Conversely, certain auxin pathway genes and many root-regulatory genes were derepressed through H3K27 demethylation. Our data indicate that genome-wide H3K27me3 reprogramming, through the PcG-mediated H3K27me3 and the H3K27 demethylation pathways, is critical in directing cell fate transition. This submission represents the gene expression component of the study Leaves from 20-day-old seedlings of wild-type Col-0 and 20-DAC calli were used for RNA preparation.

Gene expression profiling of rice embryogenic calli after Agrobacterium infection

Project description:Agrobacterium tumefaciens-mediated genetic transformation has been routinely used in rice for more than a decade. However, the transformation efficiency of the indica rice variety is still unsatisfactory and much lower than that of japonica cultivars. Further improvement on the transformation efficiency lies in the genetic manipulation of the plant itself, which requires a better understanding of the underlying process accounting for the susceptibility of plant cells to Agrobacterium infection as well as the identification of plant genes involved in the transformation process. In order to investigate the related genes affecting the transformation efficiency of embryogenic calli of different rice cultivars, we used Affymetrix GeneChipM-BM-. Rice Genome Array to measure the global gene expression profiling just before transformation and at four different time points after transformation (1 h, 6 h, 12 h, 24 h) in both japonica rice cultivar Nipponbare and indica rice cultivar Zhenshan 97. The mature embryo-derived embryogenic calli of Nipponbare (Nip) and Zhenshan 97 (ZS) were infected by Agrobacterium. Calli of Nip and ZS were sampled just before infection (0 h) and 1h, 6h, 12 h and 24h after infection, respectively. Three independent biological replications for each time point of the two varieties were used. To avoid the influence of polymorphisms between the probe sequence on the array and the genomes of the varieties used, we used a genomic DNA (gDNA)-based probe-selection strategy based on the hybridization efficiency of gDNA from Nip and ZS with the PM oligonucleotide probes on the rice array. The genomic DNA of Nip and ZS were extracted and hybridized to the Affymetrix Rice Genome Arrays. Three biological replications per cultivar were performed.
