title: Responses to low phosphorus conditions of <i>Triadic sebifera</i> (Euphorbiaceae), an invasive plant species on Miyajima Island, southwest Japan

description: Phosphorus (P) is a crucial nutrient for plant growth, but its availability in soils is often limited. Invasive plants have shown enhanced utilization of essential elements in soil, including P, compared to native plants, contributing to their success. This study investigated the responses of <i>Triadic sebifera</i>, an invasive species, to low P conditions. We compared <i>T. sebifera</i> with native <i>Mallotus japonicus</i> and other local plants in field conditions and further examined <i>T. sebifera</i>‘s response to low P availability using hydroponic systems and RNA-seq analysis. The hydroponic experiments involved three treatment groups with different P concentrations (0, 6.4, and 64 µM ). Field survey results revealed that <i>T. sebifera</i> exhibited higher P use efficiency and more efficient P resorption compared to other native plants on Miyajima Island. However, no significant differences in P concentrations were found between <i>T. sebifera</i> and native plant <i>M. japonicus</i>, another member of the Euphorbiaceae family. This suggests that the efficient use and resorption of P may not be unique to the invasive species <i>T. sebifera</i>, but rather a trait shared by members of the Euphorbiaceae family. Hydroponic experiments further demonstrated the response of <i>T. sebifera</i> to low P availability. Under 0 µM P treatment, <i>T. sebifera</i> showed enhanced secretion of acid phosphatase (AcPase). At 6.4 µM P treatment, the plant maintained growth, exhibited potential enhancement in root development, high chlorophyll content, and high root biomass, and demonstrated relatively high AcPase secretion, but displayed a P-deficient state compared to the 0 and 64 µM P treatments. RNA-seq analysis provided insights into the potential strategies of <i>T. sebifera</i> in low P environments. It revealed that <i>T. sebifera</i> under 0 µM P treatment exhibits upregulation of transcripts related to P acquisition, antioxidant activities, stress responses, and arsenate uptake risk or regulation. Additionally, <i>T. sebifera</i> showed upregulation of transcripts associated with secondary metabolism under 6.4 µM P treatment, suggesting mechanisms for more efficient P acquisition and environmental stress defense. This study highlights the strategies of <i>T. sebifera</i> under low P availability, suggesting a role in enhancing its own P utilization efficiency, which may contribute to its successful invasion.

title: Effect of different light conditions on the growth response of sugar beet to NaCl

description: It is known that sugar beet, derived from a halophytic wild ancestor, is highly salt-tolerant and that moderate concentrations of NaCl enhance its growth. However, the mechanisms of this improved growth performance by NaCl are not fully understood. In this study, we investigated the effects of NaCl on sugar beet growth under different light conditions and examined the relationship between light-induced oxidative stress and the beneficial effects of NaCl. Sugar beet seedlings in pots filled with fertilized soil were grown with different light intensities (low: 150–250 μmol m<sup>−2</sup>s<sup>−1</sup> or high: 600–1,000 μmol m<sup>−2</sup>s<sup>−1</sup>) and NaCl treatments (irrigation with water with or without 50 mM NaCl) for 10 days. The enhanced sugar beet growth by NaCl application was only observed in plants with high light intensity treatments. Moreover, high light intensity treatment increased the shoot concentration of malondialdehyde, an indicator of oxidative stress, while NaCl application decreased it. While there was a positive correlation between Na concentration and the compatible solute glycine betaine in the shoots and roots under both light intensities, a significant negative correlation between the concentrations of glycine betaine and malondialdehyde was found only in the shoots under high light intensity. Because it is known that glycine betaine activates antioxidant enzyme activities and reduces oxidative stress responses, glycine betaine synthesized in response to NaCl accumulation may have reduced the oxidative stress caused by high light intensity in the shoots, which may have caused the enhanced growth in sugar beet. Furthermore, the growth promotion by NaCl accumulation was accompanied by a significant decrease in NO<sub>3</sub>–N concentration, which suggested that NaCl application affects nitrogen metabolism in sugar beet.

title: Steel slag-based silicate fertilizer suppresses grain cracking in brewer’s rice cultivar “Yamada-Nishiki”

description: In recent years, high temperatures during rice ripening have caused the impairment of rice grain filling, resulting in cracked grains and chalky grains in rice for Japanese sake brewing (brewer’s rice) and reduced suitability for brewing. In particular, cracked grains break during rice polishing, making it difficult to use the rice for brewing. Because brewer’s rice with many cracks has a lower quality grade, for farmers it is crucial to suppress grain cracking. A previous study reported the effectiveness of silicate fertilizer as a technique to suppress grain cracking and chalky grains in ‘Toyonishiki,’ which was a rice cultivar used by brewers . In the present study, we examined whether the application of steel slag-based silicate fertilizer to ‘Yamada-Nishiki,’ the most commonly grown brewer’s rice cultivar in Japan, could effectively suppress grain cracking under high-temperature stress during the grain-filling period. In 2021–2022, brewer’s rice ‘Yamada-Nishiki’ was cultivated in a paddy field in Tainai City, Niigata Prefecture, Japan, by applying a standard amount (1000 kg/ha) of steel slag-based silicate fertilizer (23% soluble silicate, 12% total iron, 40% alkali constituents). For high-temperature treatment, small plastic greenhouses were set up in the paddy field during the heading period for 20 days. The two-year field cultivation test results demonstrated that applying silicate increased its concentration in hulls. Moreover, the high-temperature treatment led to a significantly higher percentage of cracked grains, whereas silicate application resulted in a notably lower percentage. This revealed a strong negative correlation between silicate concentration in rice hulls and the incidence of cracked grains. In addition, when the harvested rice was air-dried at 50°C in a ventilated dryer, the rate of decrease in the moisture content of unhulled rice was slower in the silicate treatment and the ratio of cracked grains of silicate-applied rice was also lower. These findings suggest that the use of silicate fertilizers led to significant silicate deposition in rice hulls during ripening, and this deposition slowed down the rate of moisture content reduction in unhulled rice during drying, consequently suppressing cracking in Yamada-Nishiki.

title: Seed glucosinolates in rapeseed (<i>Brassica napus</i>) provide sulfur nutrition required for early seedling growth under sulfur limitation

description: <i>Brassica</i> crops accumulate specific sulfur (S)-containing compounds, glucosinolates (GSL), in their seeds. GSL function in plant defense, but a few exert toxic effects on animals. Rapeseed (<i>Brassica napus</i>) cultivars accumulating low levels of GSL have been bred to avoid the toxic effects of GSL. GSL store S to support early seedling growth in <i>Arabidopsis</i> under S deficiency. In this study, we tested the effects of different S conditions on growth and S metabolism in <i>B. napus</i> cultivars containing high and low GSL concentrations in the seeds (hereafter referred to as high- and low-seed GSL cultivars, respectively) to determine the appropriate fertilizer design for <i>B. napus</i>. Seed S content was lower in the low-seed GSL cultivars than that in the high ones, indicating that seed GSL content can contribute S accumulation in <i>B. napus</i> seeds. Under S-sufficient (+S) and -deficient (–S) conditions, both shoots and roots fresh weights were similar among the cultivars, but the leaves turned yellowish in the low-seed GSL cultivars. The sulfate and cysteine levels in the seedlings were similar among the cultivars, but glutathione content was lower in the low-seed GSL cultivars than that in the high-seed GSL cultivars, especially in the shoots grown under – S conditions. The S levels in the protein fraction were lower in the shoots of the low-seed GSL cultivars than in those of the high-seed GSL cultivars. These results indicated that seed GSL help support early seedling growth in <i>B. napus</i> under – S conditions. S deficiency and lack of GSL affected shoot growth rather than root growth. Thus, we recommend applying S fertilizers to low-seed GSL cultivars and minimizing the use of S fertilizers for high-seed GSL cultivars. This study provides novel insights for designing and applying fertilizers according to the <i>B. napus</i> cultivar and the soil environment.
