Invertase or sucrose synthase breaks down sucrose in sink organs to produce carbon and energy for development and the accumulation of storage reserves including starch (Lunn 2016). During starch synthesis from sucrose, the formation of adenosine diphosphate glucose (ADP-Glc), a substrate used in starch biosynthesis, is

However, the transcriptional regulatory networks of the synthesis and accumulation of storage substances remain largely unknown. Here, we identified a rice endosperm-specific gene, NF-YC12, that encodes a putative nuclear factor-Y transcription factor subunit C. NF-YC12 is expressed in the aleurone layer and starchy endosperm during grain
Structurally, rice seeds mainly comprise the spikelet hull, seed coat, aleurone layer, embryo, and endosperm. Among them, the size of spikelet hull is the key

Soluble sugar in rice seed is an important energy storage substance and the main source of sweet taste, and its content is closely related to the nutrition and quality of rice (Zhu, Cheng, Liu
Here, a mass spectrometry-based comparative metabolomic study was performed for rice seeds before and after 24-month natural storage between two hybrid
Also mutants with perturbation in storage starch biosynthesis are often disadvantaged, and mutant seeds with low or no starch may even be inviable [5, 6]. It is this storage starch that we consume as our food and extract for industrial uses—it can account for 70–80 % of the dry weight in wheat grains and cassava roots [7, 8].
Rice (Oryza sativa) is an important food crop that feeds more than half of the world''s population. Rice endosperm occupies most of the space in the mature seed and provides energy and materials for seed germination and seedling development [1]. Among all the nutritional components in rice endosperm, crude fat content (CFC) is one major
We used proteomic analysis to determine the response of rice plant seedlings to drought-induced stress. The expression of 71 protein spots was significantly altered, and 60 spots were successfully identified. The greatest down-regulated protein functional category was translation. Up-regulated prote
Protein is the second type of storage substances in rice seeds, generally accounting for about 8%–10% of the dry weight of brown rice. The contents of protein and amino acids in rice seeds and their relative balance are the most important factors determining the nutritional value of rice ( Liang et al, 2015 ; Lu et al, 2022 ).
International Review of Cell and Molecular Biology. Vito M. Butardo Jr., Nese Sreenivasulu, in International Review of Cell and Molecular Biology, 2016 4 Increasing Protein Content and Enhancing Essential Amino Acid Composition. Aside from providing carbohydrates, rice grain is a valuable source of storage macronutrients such as proteins (Fig. 1) is a less
Finally, the introduction of the RGA1 mutant allele into two indica rice varieties also resulted in small and round rice grains with less chalkiness. Conclusions: These results indicate that RGA1 is not only involved in the control of rice architecture and grain size, but also in the regulation of rice quality and seed germination. This study
In general, the main components of rice grain quality are milling quality (MQ), appearance quality (AQ), eating and cooking quality (ECQ), and nutritional quality (NQ). coordinates various pathways to regulate endosperm development and the accumulation of seed storage substances in rice. The phenotype of the osnf-yb12
Alpha-amylase isozyme 3E and seed allergy protein RA5 may be the key proteins to regulate grain storage substance accumulation and further influence quality under elevated temperature. This study enriched the regulatory factors involved in the response to elevated temperature and provided a new idea for a better understanding of
Seed storage substances and compound starch granules are altered in nf-yc12endosperm. To investigate the intrinsic changes of grains in nf-yc12, we exam- ined the contents of storage substances in mature seeds. The total starch and amylose contents were significantly lower than those in the WT (Fig. 3A, B).
coating substances against rice seed bome Rice was applied The main plot was seed coating substances, which weze (CA), only chitosm lignos.iphcnate The storage was carried out
For Ilpum, the total tocopherol ( 17 – 20) levels in rice seed lipid extract decreased from 229.36 to 101.51 mg/100 g lipid extract, while the total tocotrienol ( 21, 23, 24) levels increased from 23.49 to 62.45 mg/100
Natural variation of seed storability in rice. To elucidate the genetic basis of the natural variation of seed storability in rice germplasm, the seed germination percentage of 252 rice accessions (Supplemental Data Set S1) was measured at the freshly harvested stage and every three months after harvest during 24 months of storage under
Conclusions: These results indicate that RGA1 is not only involved in the control of rice architecture and grain size, but also in the regulation of rice quality and seed germination. This study sheds new light on the biological functions of RGA1, thereby providing valuable information for future systematic analysis of the G-protein pathway and
Presently, chemical seed treatments are in discussion due to their directly or indirectly impacts on human health or other living organisms. They may also negatively affect the ecosystem and the food chain. In rice seeds, chemicals may cause phytotoxic effects including seed degradation. Eugenol is

Background: Starch is the main storage substance in rice caryopsis and its properties will determine the quality of rice. Super rice has been extensively studied due to its high-yield characteristics, but the knowledge of amyloplast development and starch quality in caryopsis of super rice especially with large panicle is limited.
Seed priming is a successful practice to improve crop establishment under adverse environment. However, reduced longevity of primed rice (Oryza sativa L.) seeds during storage limited the adoption of this technique.Present study investigated the effect of temperature, relative air humidity (RH) and oxygen on the longevity of primed rice seeds

As a major food, rice has a huge stock for production and consumption worldwide, while easily losing food value and seed viability during storage. Thus, understanding the physiological responses and molecular mechanisms of aging tolerance
Starch, as a main energy storage substance, plays an important role in plant growth and human life. In this study, we isolated a rice floury endosperm mutant M14 from a mutant pool induced by 60 Co. Both total starch content and amylose content in M14 seeds significantly decreased, and starch thermal and pasting properties changed.
viding energy for seeds, acting as defense signaling mol-ecules, and serving as nutrients for humans and animals (Hu et al. 2015). It is generally believed that seed vigor relies on the accumulation of storage substances. As a seed matures, proteins, starches, and other substances accumulate, and the seed germination ability and vigor increase
