“…6). This finding is in agreement with the reports that the yield of japonica type varieties is much more dependent on the carbohydrates produced from the photosynthates after heading than from the stored ones in shoot before heading (Matsushima and Wada 1958;Yoneyama et al 1989). Panicle weight of GZ and BR was associated both with the loss of shoot weight due to the translocation of shoot matter to the panicles and photosynthates during RP.…”

“…Indeed, the PSTOL1 -gene introduction increased the root weight and length and nutrient uptake (P, K, and N). The enhanced uptake of these nutrients due to abundant roots and an efficient nutrient distribution to grains had previously been recorded in high-yielding rice varieties (Murakami and Yoneyama, 1988; Yoneyama et al, 1989). …”

“…During this period, vegetative organs slow growth, whereas the top four leaves are quite active in photosynthesis, and Rubisco proteins are maintained with low degradation rates, and significant amounts of organic N compounds and carbohydrates are stored in stems and leaf sheaths (Yoneyama et al, 1989). These are used subsequently at the rapid events of heading, flowering and pollination, which occur during the 4 days after heading.…”

A single germinated rice (Oryza sativa L) seed can produce 350 grains with the sequential development of 15 leaves on the main stem and 7–10 leaves on four productive tillers (forming five panicles in total), using nitrogen (N) taken up from the environment over a 150-day growing season. Nitrogen travels from uptake sites to the grain through growing organ-directed cycling among sequentially developed organs. Over the past 40 years, the dynamic system for N allocation during vegetative growth and grain filling has been elucidated through studies on N and 15N transport as well as enzymes and transporters involved. In this review, we synthesize the information obtained in these studies along the following main points: (1) During vegetative growth before grain-filling, about half of the total N in the growing organs, including young leaves, tillers, root tips and differentiating panicles is supplied via phloem from mature source organs such as leaves and roots, after turnover and remobilization of proteins, whereas the other half is newly taken up and supplied via xylem, with an efficient xylem-to-phloem transfer at stem nodes. Thus, the growth of new organs depends equally on both N sources. (2) A large fraction (as much as 80%) of the grain N is derived largely from mature organs such as leaves and stems by degradation, including the autophagy pathway of chloroplast proteins (e.g., Rubisco). (3) Mobilized proteinogenic amino acids (AA), including arginine, lysine, proline and valine, are derived mainly from protein degradation, with AA transporters playing a role in transferring these AAs across cell membranes of source and sink organs, and enabling their efficient reutilization in the latter. On the other hand, AAs such as glutamine, glutamic acid, γ-amino butyric acid, aspartic acid, and alanine are produced by assimilation of newly taken up N by roots and and transported via xylem and phloem. The formation of 350 filled grains over 50 days during the reproductive stage is ascribed mainly to degradation and remobilization of the reserves, previously accumulated over 100 days in the sequentially developed vegetative organs.

“…Crop yields can also provide the weight of carbon in grain according to the chemical formula of starch as (C 6 H 10 O 5 ) n . Crop scientists [7,8,9] have investigated carbon partitioning in rice to elucidate carbon, nitrogen, and root effects on rice photosynthesis and production. Validation of the photosynthetic sterility model uses carbon weights included in county and city scales of …”

Sustainability of world crop production and food security has become uncertain. The authors have developed an environmental research system called Remote Sensing Environmental Monitor (RSEM) for treating carbon sequestration by vegetation, grain production, desertification of Eurasian grassland, and CDM afforestation/ reforestation to a background of climate change and economic growth in rising Asian nations. The RSEM system involves vegetation photosynthesis and crop yield models for grains, including land-use classification, stomatal evaluation by surface energy fluxes, and daily monitoring for early warning. This paper presents a validation method for RSEM based on carbon partitioning in plants, focusing in particular on the effects of area sizes used in crop production statistics on carbon fixation and on sterility-based corrections to accumulated carbon sequestration values simulated using the RSEM photosynthesis model. The carbonhydrate in grains has the same chemical formula as cellulose in grain plants. The method proposed by partitioning the fixed carbon in harvested grains was used to investigate estimates of the amounts of carbon fixed, using the satellite-based RSEM model.
