Proteomic analysis of somatic embryo development in Musa spp. cv. Grand Naine (AAA)

ABSTRACT: Somatic embryos are very much similar to zygotic counterparts in many morphological aspects and the somatic embryos are derived from somatic cells by undergoing various metabolic regulations. The somatic embryos have been used in artificial seed technology, genetic engineering and germplasm conservation. Though somatic embryo development is an important topic in growth and developmental studies, the molecular mechanism underlying the developmental process remains unclear. Therefore, understanding the molecular basis behind somatic embryo development can provide insight on the signaling pathways integrating this process. Proteomic analysis of somatic embryo development in cv. Grand Naine (AAA) was carried out to identify the differentially accumulated protein using two dimensional gel electrophoresis coupled with mass spectrometry. In total, 25 protein spots were differentially accumulated in different developmental stages of somatic embryos. Among them, three proteins were uniquely present in 30 days globular stage somatic embryos and six proteins were uniquely present in 60 days matured somatic embryo. Functional annotation of identified spots showed that major proteins are involved in growth and developmental process (17 %) followed by defense response (12%) and signal transportation events (12 %). In early stage, cell division and growth related proteins were involved in the induction of somatic embryos whereas in late developmental stage, cell wall modification proteins along with stress related proteins like played a defense role against dehydration and osmotic stress and resulted in maturation of somatic embryo. Alongside some identified stage specific proteins are valuable indicators and have been used as genetic markers.

Somatic embryos are comparable to their zygotic counterparts for morphological traits but are derived from somatic cells through various metabolic regulations, collectively referred as somatic embryogenesis (SE). It has been well exploited for germplasm conservation, genetic engineering, mutation breeding, for artificial seed technology and as a tool for mass multiplication. Though somatic embryo development is an important area of interest in growth, and developmental studies, the underlying mo ...[more]

Project description:Sour passion fruit (Passiflora edulis Sims) has economic and social relevance and is an alternative crop mainly for family farming agriculture. The use of micropropagation by somatic embryogenesis offers scale-up clonal propagation with high phytosanitary quality. The aim of this work was to evaluate the influence of polyethylene glycol (PEG) on the maturation of somatic embryos associated with differential accumulation of proteins and changes in the endogenous polyamines (PAs) content during somatic embryogenesis of P. edulis ‘UENF Rio Dourado’. Maturation of somatic embryos was performed using embryogenic callus in MS culture medium with PEG 6% or without PEG (control). PEG 6% promoted the maturation of a significantly higher number of somatic embryos at globular and cotyledonary stages when compared to control treatment. The higher somatic embryo formation induced by PEG 6% was associated with an increase in endogenous contents of free spermine, a PA with an important role in the maturation process of somatic embryogenesis cultures. PEG also promoted a significantly higher content of putrescine and total free PAs at the end of maturation, which was relevant for the increase in the number of somatic embryos. Comparative proteomic analyses of PEG 6%/control revealed that PEG 6% treatment induced the up-accumulation of proteins related to the glycolytic process, generation of precursor metabolites energy, and response to light stimulus, we can highlight the enolase ENO1, triosephosphate isomerase (TPI), ribulose bisphophate carboxylase/oxygenase activase chloroplastic (RCA), glyceraldehyde-3-phosphate dehydrogenase GAPCP-1, chloroplastic (GAPCP-1), succinate dehydrogenase [ubiquinone] flavoprotein subunit1, mitochondrial (SDH1-1), pyruvate dehydrogenase E1 component subunit alpha, mitochondrial (IAR4), ATP synthase CF1 beta subunit (PB), malate dehydrogenase [NADP], chloroplastic (AT5G58330) and chlorophyll a-b binding protein 21, chloroplastic (LHB1B1), and the down-accumulated proteins related mainly to the cellular metabolic process with proteins such as NADP-dependent malic enzyme (NADP-ME4), phosphoenolpyruvate carboxylase 2 (PPC1), UDP-glucose 6-dehydrogenase 1 and 4 (UGD2) and sucrose synthase 2 isoform X2 (SSA) and cell division cycle protein 48 homolog (ATCDC48B). The use of PEG induced thematuration and development of somatic embryos of P. edulis Sims ‘UENF Rio Dourado’ by the differential accumulation of proteins and modulation of endogenous contents of PAs

Project description:Sugarcane (Saccharum spp.) is one of the most important crops for sugar, biofuels and bioenergy production, becoming an important commodity in the world agricultural market for more than 100 countries. In this study, label-free quantitative proteomics and phosphoproteomics analyses were performed to investigate signaling events related to somatic embryo maturation and differentiation in sugarcane. Embryogenic callus (EC) at the multiplication (EC0) and after 14 days (EC14) under maturation were compared. A total of 251 phosphoproteins and 700 proteins were differentially regulated and accumulated, respectively, in the EC14/EC0 comparison. Metabolic pathways analysis showed that proteins and phosphoproteins are enriched in lysine degradation and starch/sucrose metabolism during multiplication, while differentiation of somatic embryo involves the regulation of energetic metabolism, including TCA cycle, oxidative phosphorylation, and carbon metabolism. Multiplication-related phosphoproteins were mainly associated to abscisic acid responses and transcriptional regulation comprising the TOPLESS (TPL), SNF1 kinase homolog 10 (KIN10), SEUSS (SEU), and LEUNIG_HOMOLOG (LUH) proteins. In maturation-related phosphoproteins, the phosphorylation of the proteins light harvesting complex photosystem ii, CURVATURE THYLAKOID 1B, vacuolar proton ATPase A1 and phytochrome interacting factor 3-LIKE 5 is associated to bioenergetic metabolism and carbon fixation. Motif analysis revealed 15 phosphorylation motifs, of which the [D-pS / T-x-D] motif was unique for the phosphopeptides identified during somatic embryo differentiation. Co-expression network analysis of proteins and phosphoproteins revealed the interaction between SNF1-related protein kinase 2 (SnRK2), abscisic acid responsive elements-binding factor 2 (ABF2), and KIN10, indicating the role of these proteins in the embryogenic competence in EC0. The interactions between ubiquitin-conjugating enzyme 5, ubiquitin-conjugating enzyme 35, small ubiquitin-like modifier 1, and histone deacetylase 1 may be involved in post-translational protein modification during the embryo maturation stage. argonaute 1 (AGO1) also interacts with POLTERGEIST (POL) and may integrate gene silencing and regulation of meristem identity during somatic embryo development. These results reveal novel dynamics of protein regulation in somatic embryogenesis and identify new potential players in somatic embryo differentiation and their phosphosites.
