In this study, antixenosis and tolerance were examined as the factors of resistance to rice stink bugs attack of rice line CRR-99-95 W. Two experiments were conducted to determine a possibility of antixenosis involvement as a factor of the resistance in CRR-99-95 W. The results showed no correlation between the number of Leptocorisa chinensis parasites and pecky rice incidence. Furthermore, no significant difference was found between the sucking frequency of Nezara viridula on mature husks of CRR-99-95 W and that on the check genotypes. These results suggest that CRR-99-95 W does not exhibit antixenosis effect against rice stink bugs. Then, to examine the tolerance factor involved in the resistance mechanism, the husks structures were analyzed. The results showed that the packing ratio of cell wall of the sclerenchyma fibers in the palea tended to be higher in CRR-99-95-W compared to the check genotype. In addition, the width of the hook openness of the palea of CRR-99-95 W was narrower than that of the check genotype. Such morphological characteristic of CRR-99-95 W may play an important role in its resistance against stink bug attack.

To assess grain-filling characteristics, the allocation index (Alli) was defined as a novel indicator representing the pattern of resource allocation in panicles. Alli was calculated as the ratio of source of yield utilized for producing well-filled grains to the total source consumed in a panicle, using estimated grain weight distribution data. We measured the Alli of 91 Japanese rice cultivars grown under nine environments involving multiple years, cropping seasons, three sites, and flag leaf clipping. Each cultivar’s stability in Alli was evaluated using the data of various sink–source balance conditions. As a result of integrated analysis of multiple cultivars, we observed a trade-off relationship between the stability of Alli and the stability of mean weight of well-filled grains (mu2). The popular high-yielding cultivars Hokuriku 193 and Takanari showed high stability of Alli and mu2 under various sink–source balance conditions. Among the 91 cultivars, Hokuriku 193 showed stable characteristics with a high sink-filling ratio. Our results demonstrate that the grain weight distribution and Alli could be used as novel indicator of grain-filling characteristics, and that the trade-off relationship between the stability of Alli and mu2 should be considered when we select cultivars for multi-environmental cultivation.","PeriodicalId":20259,"journal":{"name":"Plant Production Science","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43179175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amylopectin is the largest component of rice endosperm starch and its short-chain content has a considerable effect on the eating quality of cooked rice. Here we investigated the effect of high temperature during ripening on amylopectin chain-length distribution in ‘Koshihikari’, the leading cultivar in Japan, and in ‘Ichihomare’, released in 2017 and grown in Fukui prefecture, ripened in paddies over multiple years. The amylopectin short-chain content of degree-of-polymerization (DP) 6–13 of ‘Koshihikari’ grain ripened at high temperature was 3.03 points lower than that of grain ripened at low temperature. In contrast, that of ‘Ichihomare’ was only 0.26 points lower. For every 1°C increase in temperature during ripening, the short-chain content of DP 6–13 of ‘Koshihikari’ decreased linearly by 1.03 points whereas that of ‘Ichihomare’ did not decrease significantly. These results suggest that the amylopectin chain-length distribution of ‘Ichihomare’ might be more stable to temperature during ripening than that of ‘Koshihikari’. The reason is yet unknown, but this trait will contribute to breeding and production of cultivars with stable good eating quality under high temperatures during ripening.

To increase production, breeders have selected for enlarged embryos and thickened aleurone layers. However, breeding for the latter is impeded by the time-consuming and labor-intensive process of observation of aleurone traits. Here, we established a new method for visualizing aleurone layers comprising embedding of mature grains in a plate, dichromatic staining of half grains, and computer-assisted image analysis. With this ‘plate method’, a batch of up to 100 grains fixed on the plate can be handled and examined more efficiently than the standard cryomicrotome method, which only processes the grains individually. In addition, the results obtained from the plate method were highly correlated with that of the cryomicrotome method in terms of aleurone area (r = 0.92) and mean aleurone thickness (r = 0.93). This new method allowed us to rapidly assess the aleurone phenotypes of more than 22,000 mutagenized grains of ‘Mizuhochikara’, with 700–1000 grains per day. As a result, one mutant line with thickened aleurone layer was successfully isolated.

Brachiaria ramosa, Echinochloa utilis, Eragrostis tef, and Setaria italica were used. Thirty-day old plants were hydroponically cultivated for 28 days as the control, where aeration was continued and a hypoxia treatment was applied, where nitrogen gas was flushed to reduce the oxygen concentration. From the stress susceptibility index based on plant growth rate, it was clarified that E. utilis and E. tef had higher hypoxia tolerance than B. ramosa and S. italica. Root growth rate, nitrogen concentration of leaves and stems, and sodium concentration per plant of the higher hypoxia-tolerant species did not change with hypoxia treatment. In hypoxia-susceptible millet species, the root growth rate and nitrogen concentration in the leaf and stem decreased, and the sodium concentration in the whole plant increased. The proportion of the stele area of the adventitious root of the hypoxia-tolerant millet species was smaller than that of the hypoxia-susceptible millet species, and the lysigenous aerenchyma was constitutively developed. Furthermore, root hairs were observed near the root tip in the hypoxia-tolerant millet species. In conclusion, we deduced that the hypoxia tolerance of the millet species is mainly attributable to the supply of oxygen to the root tip via the lysigenous aerenchyma along the adventitious root. Lower oxygen consumption by a smaller proportion of the stele area might be an important genetic trait. Furthermore, root hair may contribute to nutrient absorption.

Some studies on C4 grasses have reported that NADP-malic enzyme (NADP-ME) grasses have higher PNUE than NAD-malic enzyme (NAD-ME) grasses, whereas other studies have suggested that this difference is caused by the traits of phylogenetic lineage. Further extensive studies are required to properly understand the PNUE and PWUE of C4 grasses. We investigated the PNUE and PWUE for 22 grass species of four photosynthetic types [4 NADP-ME, 6 NAD-ME, 6 phosphoenolpyruvate carboxykinase (PCK), and 6 C3 species] grown under two N supply levels. Under the same N level, the three C4 types showed higher photosynthetic rate and lower stomatal conductance and transpiration rate than the C3 type, but these parameters were similar in the C4 types. Although there were no significant differences in leaf mass per area and N content per leaf area among the four types, these traits tended to be somewhat lower in the NADP-ME type than in other types. As a result, PNUE was highest in the NADP-ME type, lowest in the C3 type, and intermediate in the NAD-ME and PCK types. PWUE was much higher in the C4 types than in the C3 type but similar in the C4 types. The N supply level did not greatly affect the trends of PNUE and PWUE. This study suggests that the NAD-ME and PCK grasses have the N-related physiological traits similar to each other but differing from the NADP-ME grasses.
