“…Recently, with advances in molecular techniques, complementary theories have been proposed, including epigenetic modifications (Groszmann et al, 2013), variation in genome structure (Fu and Dooner, 2002;Song and Messing, 2003), protein-specific function, and posttranscriptional modification (Paschold et al, 2010;Liu et al, 2010;Guo et al, 2013), which have been related to the heterosis of specific tissues and stages of development. Nevertheless, most studies were carried out using fully developed plants, and little is known regarding the genetic and molecular bases of heterosis; less is known about the relationship between heterosis and seed germination.…”

ABSTRACT. In this study, we analyzed heterosis, amylase enzyme gene expression, and the physiological quality of maize seeds with different genotypes and sizes, which were subjected to aging and not subjected to aging. We used seeds from 2 maize lines that differed with regard to physiological quality, the hybrid, and the reciprocal hybrid; they were classified into 2 sizes and were subjected to aging and not subjected to aging. Physiological quality was assessed by performing tests for germination, emergence, emergence speed index, and artificial aging. Expressions of the genes alpha amylase B73, alpha amylase (LOC542522), isoamylase mRNA clone 353244, and the endogenous controls ubiquitin and alcohol dehydrogenase in the seeds were studied using quantitative real-time-polymerase chain reaction. We observed heterosis for seed quality and for expression of amylase genes in the G.E. Oliveira et al. 8624©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (3): 8623-8633 (2015) genotypes studied. We found no difference in seed quality between large and small seeds.

Section: Future Perspectives In Plant Pi Stress Proteomicsmentioning

“…Current proteomic analyses have concentrated on the root tip or suspension cell culture, but it is likely that proteins responsive to phosphate stress are expressed differently across the range of root cell types. Laser-capture microdissection has been used in a number of studies investigating the cellspecific transcriptome of plants, but is labor intensive and proteomes of laser-captured plant cell populations remain limited [60,61]. A recent report by Petricka et al [62] used FACS to separate root cell types and construct a cell-type specific proteome map in A. thaliana and this provides a prototype for future studies that could be used to reveal the Pi responses in the root:soil interface.…”

Phosphate is an essential element for plants and is involved in the composition of sugar phosphates, nucleic acids, membrane lipids, and energy metabolism via the generation of ATP. Crop farming requires the application of large amounts of phosphate fertilizer, but the fossilized rock deposits used as a commercial source of phosphate fertilizer are a nonrenewable resource that is predicted to reach a peak within the next century and drive plant production costs up as the global demand for food increases. Recent progress in the identification of key molecular regulators of the plant response to phosphate deprivation has highlighted differences in the response of the model plant Arabidopsis compared to economically important crops. This review focuses on the potential of proteomics to unravel the common and specific biochemical changes that contribute to phosphate use efficiency in cultivars of rice, maize, and oilseed rape. Proteome studies reveal a wide scope of species-specific metabolic strategies that lead to changes in root morphology and metabolism, driven by secretion of specific proteins and alteration of energy metabolism, carbon, and nitrogen assimilation inside the root cells. Understanding of the mechanisms underlying plant phosphate use efficiency in crops is critical for developing sustainable agriculture practices.

“… used a proteomic approach to the pedigree analysis of rice hybrids, and their conclusion was that proteomics analyses can be used to predict heterosis in general. Later studies confirmed the influence of heterosis at the proteomic level, and several studies have confirmed its application in exploring the posttranscriptional differences in protein levels between maize hybrids and their parent lines . The modes of proteins expression involved in heterosis in many modern hybrids at the fertilization stage have been identified .…”

Protein expression patterns were compared in a Japan and Taiwan population of Haliotis diversicolor and in a hybrid between them using 2DE and MALDI-TOF-TOF analyses. Using the software PDQuest, 924 ± 7 protein spots were detected in the Japan population (RR), 861 ± 11 in the Taiwan population (TT), and 882 ± 9 in the F1 hybrid (TR). RR and TR were clustered together, but the distance between RR and TT was the maximum using hierarchical cluster analysis. A total of 46 gel spots were identified and a total of 15 spots matched with abalone proteins (a 33.6% identification rate). Hybrid exhibiting additivity or overdominance accounted for 73.9% of these 46 identified proteins. The 46 differentially expressed proteins were shown to be involved in major biological processes, including muscle contraction and regulation, energy metabolism, and stress response. The proteins involved in energy metabolism included adenosine triphosphate (ATP) synthase β subunit, fructose 1, 6-bisphosphate aldolase, triosephosphate isomerase, enolase, arginine kinase, and tauropine dehydrogenase. These proteins exhibited additivity in their offspring. The proteins involved in stress responses included HSP Hsp70 (exhibiting overdominance in the offspring) and Cu/Zn-superoxide dismutase (exhibiting additivity). These results suggested that proteomic approach is suitable for analysis of heterosis and functional prediction of abalone hybridization.
