“…Expression profiles for each gene of single stages of the transition matched with known expression profiles (Ding et al, 2006;Tepperman et al, 2006;Hammani et al, 2011;Narsai et al, 2011;Feng et al, 2014), validating the data set. Expression data across the seven developmental stages displayed high reproducibility.…”

“…Expression data are hosted in the National Center for Biotechnology Information Gene Expression Omnibus database (http://www.ncbi.nlm.nih.gov/ geo/query/acc.cgi?token=onyxsyycjtaxxux&acc=GSE65394). Validation of the seed-to-seedling transcriptome data set was performed by comparison with previously published expression patterns of genes known to be differentially expressed across seed-to-seedling developmental stages (Supplemental Table S1; Ding et al, 2006;Tepperman et al, 2006;Hammani et al, 2011;Narsai et al, 2011;Feng et al, 2014).…”

“…Also, analysis of the expression of orthologous genes encoding PRR proteins across the same three species revealed a conservation of diurnal rhythms of expression, with sequential peaks seen across the day/night cycle, indicating that the expression pattern of these proposed interacting partners is conserved (Giraud and Whelan, unpublished data). Finally, the Wnding that a pentatricopeptide repeat protein that is dual targeted to mitochondria and the nucleus (PNM1), and interacts with TCP8 in the nucleus (Hammani et al 2011a), suggests that the regulation of nuclear genes expression by TCP transcription factors may be coordinated with expression of mitochondrial located genes via pentatricopeptide repeat proteins (Hammani et al 2011b).…”

Plant mitochondria can diVer in size, shape, number and protein content across diVerent tissue types and over development. These diVerences are a result of signaling and regulatory processes that ensure mitochondrial function is tuned in a cell-speciWc manner to support proper plant growth and development. In the last decade, the processes involved in mitochondrial biogenesis are becoming clearer, including; how dormant seeds transition from empty promitochondria to fully functional mitochondria with extensive cristae structures and various biochemical activities, the regulation of nuclear genes encoding mitochondrial proteins via regulators of the diurnal cycle in plants, the mitochondrial stress response, the targeting of proteins to mitochondria and other organelles and connections between the respiratory chain and protein import complexes. All these Wndings indicate that mitochondrial function is a part of an integrated cellular network, and communication between mitochondria and other cellular processes extends beyond the known exchange or transport of metabolites. Our current knowledge now needs to be used to gain more insight into the molecular components at various levels of this hierarchical and complex regulatory and communication network, so that mitochondrial function can be predicted and modiWed in a rational manner.

“…Furthermore, the development of robust methods to produce recombinant PPR proteins, which are predominantly insoluble, would help the analyses of their affinity and specificity for RNA targets in vitro. Nevertheless, PPR proteins have essential roles in many cellular processes, 33,37,44,45,49,55,62,66,68,[76][77][78]80,81 which makes resolving these gaps in our knowledge of fundamental importance. Furthermore, PPR proteins have a number of desirable features that make the development of their applications in biotechnology and synthetic biology quite appealing.…”
