Soybeans [Glycine max (L.) Merr] are an important source of nutrients including protein, oils and various useful secondary metabolites. Phosphatidylcholine (PC) component serves as a nerve cell membrane material and a choline supplier, so it may improve memory function in subjects suffering from memory impairment and dementia. Content of PC component in soybean seed may depend on genotype and environment. Genotype with high PC content is valuable in breeding project. Fifty-seven soybean genotypes were cultivated at first year. After harvesting, PC contents were analyzed. Content (mg/kg) of PC component was from 7.02 to 19.55. At second year, 111 genotypes including 57 genotype used at first year were cultivated. After harvesting, PC contents were analyzed. Content (mg/g) of PC component was from 0.061 to 12.324.

High temperature impediment in developing stages of crops has been occurred due to the impact of global warming. Rice production is notable to be sensitive to increasing environmental temperature and grain filling temperatures are already approaching threatening levels in many countries with rice cultivation. Recent proteomic analyses exposed impulsive changes of metabolisms during rice grain development. Interestingly, proteins involved in glycolysis, citric acid cycle, lipid metabolism, and proteolysis were accumulated at higher levels in mature grain than those of developing stages. High temperature (HT) stress in rice ripening period enhances damaged (chalky) grains which have loosely compacted shape starch granules. We carried out two-dimensional gel electrophoresis to analyze protein profiles during grain filling and different developmental stages of rice seed maturation. Proteins were separated from the fertilized seeds (seeds from 7 days and 21 days after fertilization) and seed maturation stage using IEF in the first-dimension and SDS-PAGE in the second dimension along with MALDI-TOF mass spectrometry. More than 1,000 protein spots were detected on a two-dimensional gel electrophoresis. A total of 120 different protein spots out of 140 protein spots were identified by MALDI-TOF and nano LCQ-TOF mass spectrometer. The identified proteins were categorized into six (6) different groups according to their expression patterns during grain filling and seed maturation. Some proteins were confirmed during seed development stages such as cytoplasmic malate dehydrogenase, whereas others were appeared at a specific stage like putative subtilisin-like protease, germin-like, seed allergenic proteins. Furthermore, the chalking mechanism of rice grain under the HT stress could be discussed in terms of grain starch glycome, transcriptome, and proteome.

Grain sorghum (Sorghum bicolor) is a major staple for a large portion of the world. The crop ranks fifth among the cereals world-wide with respect to its importance for food and feed applications. To this end, the grain harvested from sorghum, and the millets provides an important source for dietary calories and protein for approximately one billion people in the semi-arid regions of the world. However, grain sorghum products are known to have relatively poor digestibility, only approximately 50%–70%, in comparison with other grains, such as wheat and maize, which tend to have digestibility percentages over 80% and 70%, respectively. Protein with high digestibility is by definition nutritionally superior owing to the increased availability of amino acids. Digestibility can be impacted by both protein–protein and⁄or protein–nonprotein interactions. However, with respect to grain sorghum, it is thought that the major factor influencing digestibility is the former because of high protein cross-linking around the protein body. To understand the mechanism of seed storage proteins in the sorghum, the proteomic analysis was carried out between the wild(BTX623) and mutant(M271207) genotypes of sorghum. Proteins were separated from the mature seed using IEF in the first-dimension and SDS-PAGE in the second dimension along with hybrid LTQ-FTICR mass spectrometry. After image analysis using Progenesis SameSpot software, we identified the 62 differential expressed protein spots out of 293 protein spots. Out of total differential expressed spots, 35 differential expressed protein spots (more than2-fold) were analyzed by mass spectrometry. Out of 35 protein spots, we were identified 20 protein spots as up-regulated and 15 protein spots as downregulated, significantly. In our proteomic investigation, the candidate proteins may provide novel clues for better understanding the characteristics of seed proteins in Sorghum.

The objective of this study was to evaluate the quality characteristics of mungbean starch gels that were prepared with different concentrations (0, 0.5, 1.0 and 1.5%) of peach seed powders (PSP), which exhibit antioxidant characteristics. Mungbean starch gel samples were prepared and subjected to quality characteristics such as moisture content, general components, color, texture profile analysis, total polyphenol contents, DPPH radical scavenging activity, and sensory qualities. The L-value and the a-value for color decreased significantly, whereas the b-value increased significantly as the PSP concentration increased (p<0.05). In the texture profile analysis, the mungbean starch gel with 1.5% PSP showed significantly lower degrees of hardness, cohesiveness, springiness, gumminess and brittleness (p<0.05). The total polyphenol content was highest in the 1.5% PSP to which mungbean starch gel was added, which also showed a higher than 70% DPPH radical scavenging activity level in a dose-dependent manner (p<0.05). In the sensory test of the mungbean starch gel, its sensory scores for flavor and taste were highest in the 0.5% PSP to which mungbean starch gel was added.
