Nascent transcription defined by RNA polymerase IV in Zea mays

Project description:Maize RNA Polymerase D1 (RPD1), the largest subunit of RNA polymerase IV (Pol IV), is required for normal plant development, repression of transposable elements (TEs), and for the regulation of specific alleles associated with TEs. Here, we define the nascent transcriptomes of rpd1 mutant and wild-type (WT) seedlings using global run-on sequencing (GRO-seq) to identify the broader targets of RPD1-based transcriptional regulation. Surprisingly, although TE-like sequences comprise >85% of the maize genome, most TEs are not transcribed at the seedling stage, even in rpd1 mutants. Profile comparisons identify the global set of genes and TEs whose transcription is altered in the absence of RPD1, in some cases in antisense orientation. These results indicate that maize Pol IV specifies Pol II-based transcriptional regulation for certain regions of the maize genome.

Zea mays B73 corn-leaf aphids feeding time-course raw sequence reads

Project description:As a response to insect attack, maize (Zea mays) has inducible defenses that involve large changes in gene expression and metabolism. Piercing/sucking insects such as corn leaf aphids (Rhopalosiphum maidis) cause direct damage by acquiring phloem nutrients as well as indirect damage through the transmission of plant viruses. To elucidate the metabolic processes and gene expression changes involved in maize responses to aphid attack, leaves of inbred line B73 were infested with R. maidis for two to 96 hours.

The maize (Zea mays ssp. mays var. B73) genome encodes 33 members of the purple acid phosphatase family.

Project description:Purple acid phosphatases (PAPs) play an important role in plant phosphorus nutrition, both by liberating phosphorus from organic sources in the soil and by modulating distribution within the plant throughout growth and development. Furthermore, members of the PAP protein family have been implicated in a broader role in plant mineral homeostasis, stress responses and development. We have identified 33 candidate PAP encoding gene models in the maize (Zea mays ssp. mays var. B73) reference genome. The maize Pap family includes a clear single-copy ortholog of the Arabidopsis gene AtPAP26, shown previously to encode both major intracellular and secreted acid phosphatase activities. Certain groups of PAPs present in Arabidopsis, however, are absent in maize, while the maize family contains a number of expansions, including a distinct radiation not present in Arabidopsis. Analysis of RNA-sequencing based transcriptome data revealed accumulation of maize Pap transcripts in multiple plant tissues at multiple stages of development, and increased accumulation of specific transcripts under low phosphorus availability. These data suggest the maize PAP family as a whole to have broad significance throughout the plant life cycle, while highlighting potential functional specialization of individual family members.

The Phosphoglycerate Kinase (PGK) Gene Family of Maize (<i>Zea mays</i> var. B73).

Project description:Phosphoglycerate kinase (PGK, E.C. 2.7.2.3) interconverts ADP + 1,3-bisphospho-glycerate (1,3-bPGA) to ATP + 3-phosphoglycerate (3PGA). While most bacteria have a single pgk gene and mammals possess two copies, plant genomes contain three or more PGK genes. In this study, we identified five Pgk genes in the Zea mays var. B73 genome, predicted to encode proteins targeted to different subcellular compartments: ZmPgk1, ZmPgk2, and ZmPgk4 (chloroplast), ZmPgk3 (cytosol), and ZmPgk5 (nucleus). The expression of ZmPgk3 was highest in non-photosynthetic tissues (roots and cobs), where PGK activity was also greatest, consistent with a function in glycolysis. Green tissues (leaf blade and husk leaf) showed intermediate levels of PGK activity, and predominantly expressed ZmPgk1 and ZmPgk2, suggesting involvement in photosynthetic metabolism. ZmPgk5 was weakly expressed and ZmPgk4 was not detected in any tissue. Phylogenetic analysis showed that the photosynthetic and glycolytic isozymes of plants clustered together, but were distinct from PGKs of animals, fungi, protozoa, and bacteria, indicating that photosynthetic and glycolytic isozymes of plants diversified after the divergence of the plant lineage from other groups. These results show the distinct role of each PGK in maize and provide the basis for future studies into the regulation and function of this key enzyme.

small RNA-mediated regulation during Zea mays (maize) Somatic Embryogenesis [smRNA-Seq]

Project description:We report the role of sRNAs populations during the induction of callus tissues from VS-535 maize embryos displaying contrasting in vitro embryogenic potential; characterized through Next-generation sequencing (NGS). We conclude that the Embryogenic Response during Maize Somatic Embryogenesis induction is closely related to sRNAs regulation and depends on the developmental stage of the explant.
