“…Further, they found that this process also affects WUS and WOX genes that regulate stem cell fate. Following the same approach of global analysis but at the proteomic level, Varhanikova et al (2014) studied the proteomes of embryogenic (EC) and nonembryogenic (NEC) callus of inbred line A19. They found that increased expression of pyruvate biosynthesis genes in EC callus is in contrast with NEC callus genes expression, which in turn presented suppression of embryogenic genes by the retinoblastoma related protein (RBR).…”

Somatic embryogenesis (SE) systems in maize, have proved to be a useful tool for basic research on embryo development that lately have turned into applied research on the establishment of commercial crops. This review discusses recent findings on maize SE on basic research to reveal fundamental aspects of embryo development, its use as a biotechnological tool, and its application in the development of isogenic crops.

“…Many include the addition of growth regulators (auxin and/or cytokinin) during the induction stage (Imin et al 2005;Nolan et al 2003;Schmidt et al 1997). Several types of explants have been used for the establishment of SE including leaflets, stems, cambium, immature zygotic embryos, cell suspensions, and callus (Imin et al 2005;Varhanikova et al 2014;Correia et al 2012;Sharifi et al 2012;Guzmán-García et al 2013). SE can be induced directly from the explant (direct embryogenesis) or indirectly through the formation of somatic embryos from callus or suspension cultures (George et al 2008).…”

“…Pioneering microscopy observations distinguished the generation of embryogenic and non-embryogenic tissues from the same explants. Both of these tissues can be maintained in culture for long periods of time, maintaining their particular identities (Varhanikova et al 2014;Correia et al 2012;Marsoni et al 2008;Sharifi et al 2012;Nomura and Komamine 1985;Pennell et al 1992). In general embryogenic cultures comprise compact globular masses with clusters of meristematic cells (small, highly cytoplasmic, and mostly containing starch) while in non-embryogenic cultures it is common to observe fast growing large parenchymal cells (vacuolated, amorphous, and translucent in appearance).…”

“…7.1). These pairs of distinct cultures have been analyzed using proteomics tools with the goal of identifying proteins markers associated with embryogenic potency (Varhanikova et al 2014;Correia et al 2012;Marsoni et al 2008;Sharifi et al 2012;Almeida et al 2012;Guzmán-García et al 2013). However, these studies have not used sufficiently robust proteomics pipelines and therefore have not covered a comprehensive proportion of the proteome during initiation of the acquisition of the embryogenic potency (Rode et al 2011(Rode et al , 2012.…”

“…These comprehensive studies allow us to identify specific modifications of genome architecture through epigenetic regulation during SE (Feher 2015;Nic-Can et al 2013;Imin et al 2005). Furthermore, proteomic studies of SE in several species have created protein profiles of cultures in different conditions during the induction of embryogenic potential (Varhanikova et al 2014;Correia et al 2012;Marsoni et al 2008;Sharifi et al 2012;Almeida et al 2012;Guzman-Garcia et al 2013). These studies have been followed up with the focused identification of key proteins associated with each stage of the transdifferentiation of somatic embryos (Rode et al 2012;Bian et al 2010;Vale Ede et al 2014).…”

Somatic embryogenesis includes the genetic reprogramming of somatic cells to acquire the embryogenic potency necessary to generate an embryo, which can develop into a whole plant. Acquisition of embryogenic capacity requires rigorous biochemical coordination that includes several metabolic and signal transduction pathways. Recent genomic and epigenetic studies in somatic embryogenesis have shown interconnection among signals associated with growth regulators, stress factors, and modulation of the genome structure. A broad range of key proteins, posttranslational modifications, protein turnover, and protein-protein interactions are common factors associated with the establishment of the necessary biochemical status of cells during the acquisition of the embryogenic potential. Recent proteomic studies have begun describing the molecular basis of somatic embryogenesis. However, the diversity of the embryogenic response among plant species makes it difficult to define key protein factors associated with embryogenic cultures or specific stages during the transdifferentiation of somatic embryos. In this chapter, we review the most prominent proteomic studies carried out in the past E.

Somatic embryogenesis, is a process by which new viable embryos are produced from somatic tissues. Somatic embryogenesis is not only a useful biotechnological tool for the massive clonal propagation and genetic engineering but it also allows to obtain fundamental knowledge about the molecular changes that take place during embryogenesis. We present the proteome profile of two embryogenic cell suspensions. We identified 1052 non-redundant proteins. We present their known GO annotations and show two protein networks sharing the GO annotations related to stress and embryogenic capacity via the free program Cytoscape. To our knowledge these results give the first high-throughput proteome description of embryogenic cell suspensions and provide new information about somatic embryos for the whole plant community. The published proteome is a first step toward understanding somatic embryogenesis in coffee and toward a better annotation of proteins in an important non-model crop. All data are available via ProteomeXchange with identifier PXD002963.
