Plant. Nutr. (IF 1.432) Pub Date : 2020-06-18 Satoshi Suzuki; Tsutomu Imura; Yasuo Kobayashi; Masao Usui; Naruo Miyazaki; Toshio Sano
Following the Fukushima Daiichi Nuclear Power Plant accident of 2011, the potential for radiocesium transfer from contaminated soils, such as Andosols, to agricultural crops became a significant concern. Andosols account for up to 70% of paddy soils in the northern and northwest areas of Tochigi Prefecture, where the radiocesium concentration is 1000 Bq kg−1 or greater in the soil of some fields. The

Classification of volcanic soils in the Soil Classification System of Japan and verification based on forest soils Soil Sci. Plant. Nutr. (IF 1.432) Pub Date : 2020-06-30 Akihiro Imaya
In 2017, the Japanese Society of Pedology (the Fifth Committee for Soil Classification and Nomenclature) established the Japanese soil classification system. In the classification system, all the soils derived from volcanic ejecta (volcanic ash, pumice, scoria, etc.) are classified into the Great Group of Andosols, excluding Man-made and Organic soils, although some volcanic soils were classified into

The diversity of volcanic soils: focusing on the function of aluminum–humus complexes Soil Sci. Plant. Nutr. (IF 1.432) Pub Date : 2020-06-08 Tadashi Takahashi
Andosols (or Andisols) are the typical soils developed from volcanoclastic materials. They possess several distinctive properties that are rarely found in other groups of soils. These properties are largely due to the dominance of short-range ordered minerals (allophane, imogolite, and ferrihydrite) and/or mineral–humus complexes (Al/Fe–humus complexes). In this review, I survey the diversity of volcanic

Physicochemical and time factors affecting 137Cs transfer through a paddy soil–rice system Soil Sci. Plant. Nutr. (IF 1.432) Pub Date : 2020-07-27 Seiko Yoshikawa; M. Igura; T. Yasutaka; S. Eguchi
ABSTRACT To clarify the factors affecting 137Cs transfer from soil to brown rice in comparison with 133Cs transfer and also to determine the key parameters of the solid-liquid partition coefficient (K d), concentration factor from soil solution to brown rice (CF), and transfer factor from soil to brown rice (TF), we analyzed the results of our previous paper in which a rice pot-culture experiment under

Relationships between yield of winter wheat and bacterial and protozoan fatty acids affected by different green manure amendments Soil Sci. Plant. Nutr. (IF 1.432) Pub Date : 2020-07-25 Takuma Miyamoto; Arata Tarui; Hiroyuki Daimon; Atsushi Matsumura
ABSTRACT Soil microorganisms play important roles in crop growth and nutrient cycling. This study investigated the influence of the temporal changes in soil fatty acids (FAs) mainly derived from microorganisms by the incorporation of different green manures on the subsequent crop yield of winter wheat. Plants (Sesbania rostrata or Sorghum bicolor) as green manure were cultivated as the preceding crop

The bHLH protein OsIRO3 is critical for plant survival and iron (Fe) homeostasis in rice (Oryza sativa L.) under Fe-deficient conditions Soil Sci. Plant. Nutr. (IF 1.432) Pub Date : 2020-07-23 Fan Wang; Reiko N. Itai; Tomoko Nozoye; Takanori Kobayashi; Naoko K. Nishizawa; Hiromi Nakanishi
ABSTRACT Iron (Fe) is an essential element for most organisms since it is involved in various biological reactions. Fe deficiency is a major constraint for plant growth and leads to low crop yields and poor nutritional quality. Fe uptake and translocation in plants require the coordinated expression of multiple genes, which is regulated by various transcription factors (TFs), especially members of

Effects of overexpression of the Rubisco small subunit gene under the control of the Rubisco activase promoter on Rubisco contents of rice leaves at different positions Soil Sci. Plant. Nutr. (IF 1.432) Pub Date : 2020-07-14 Natsumi Kudo; Kazuhisa Mano; Mao Suganami; Eri Kondo; Yuji Suzuki; Amane Makino
ABSTRACT Photosynthetic activity is expected to be maintained during leaf senescence if the amount of Rubisco is maintained. As the mRNA level of the Rubisco gene decreases rapidly just before the stage of full expansion, its overexpression after full expansion would be effective. We previously found that the mRNA level of the Rubisco activase gene (RCA) is maintained during leaf senescence. In the
