Strategies to prevent the growth of mycotoxin-producing fungi in agricultural products need to be identified. In this study, the antifungal efficacy of Perilla frutescens essential oil (PEO) as a fumigant against Aspergillus flavus (A. flavus ) in stored rice seeds was investigated. PEO affected the permeability and integrity of the A. flavus cell membrane, as evidenced by the decreased cell viability. In situ assays demonstrated that fumigation with PEO significantly reduced and retarded the growth of A. flavus in stored rice seeds but the germination rate decreased with increasing concentration of PEO. PEO could alleviate rice seeds’ color differences by reducing the degree of rice seeds browning, as evidenced by a decrease in polyphenol oxidase in PEO-fumigated rice seeds. Moreover, the rice seeds with PEO fumigation exhibited higher soluble protein content and catalase (CAT) activity, which collectively suggests that PEO promotes the tolerance of rice seeds to A. flavus . Furthermore, decreases in fatty acid value (FAV), malondialdehyde (MDA) content, and acceptable sensorial characteristics were observed in the rice seeds after PEO fumigation, indicating that fumigation with PEO can effectively delay the trend of quality deterioration in high moisture rice seeds during storage. These results recommended PEO as a potential green preservative for the shelf-life extension of stored grain.

This study was conducted to reveal the effects of silicon(Si) application on nutrient utilization efficiency by rice and on soil nutrient availability and soil microorganisms in a hybrid rice double-cropping planting system. A series of field experiments were conducted during 2017 and 2018. The results showed that Si nutrient supply improved grain yield and the utilization rates of nitrogen(N) and phosphorus(P) to an appropriate level for both early and late plantings, reaching a maximum at 23.4 kg/ha Si. The same trends were found for the ratios of available N(AN) to total N(TN) and available P(AP) to total P(TP), the soil microbial biomass carbon(MBC), microbial biomass nitrogen(MBN), microbial biomass phosphorus(MBP), and the ratios of MBN to TN and MBP to TP, at different levels of Si. Statistical analysis further revealed that Si application enhanced rice growth and increased the utilization rate of fertilizer due to an ecological mechanism, i.e., Si supply significantly increased the total amount of soil microorganisms in paddy soil compared to the control. This promoted the mineralization of soil nutrients and improved the availability and reserves of easily mineralized organic nutrients.

Conserved pathogen-associated molecular patterns （PAMPs）, such as chitin, are perceived by pattem recognition receptors （PRRs） located at the host cell surface and trigger rapid activation of mitogen- activated protein kinase （MAPK） cascades, which are required for plant resistance to pathogens. However, the direct links from PAMP perception to MAPK activation in plants remain largely unknown. In this study, we found that the PRR-associated receptor-like cytoplasmic kinase Oryza sativa RLCK185 transmits immune signaling from the PAMP receptor OsCERK1 to an MAPK signaling cascade through interaction with an MAPK kinase kinase, OsMAPKKKε, which is the initial kinase of the MAPK cascade. OsRLCK185 interacts with and phosphorylates the C-terminal regulatory domain of OsMAPKKKε. Coexpression of phosphomi- metic OsR LCK185 and OsMAPKKKε activates MAPK3/6 phosphorylation in Nicotiana benthamiana leaves. Moreover, OsMAPKKKε interacts with and phosphorylates OsMKK4, a key MAPK kinase that transduces the chitin signal. Overexpression of OsMAPKKKε increases chitin-induced MAPK3/6 activation, whereas OsMAPKKKε knockdown compromises chitin-induced MAPK3/6 activation and resistance to rice blast fungus. Taken together, our results suggest the existence of a phospho-signaling pathway from cell surface chitin perception to intraceilular activation of an MAPK cascade in rice.

ABSTRACT Plant hormones have been extensively studied for their importance in innate immunity particularly in the dicotyledonous model plant Arabidopsis thaliana. However, only in the last decade, plant hormones were demonstrated to play conserved and divergent roles in fine-tuning immune responses in rice （Oryza sativa L.）, a monocotyledonous model crop plant. Emerging evidence showed that salicylic acid （SA） plays a role in rice basal defense but is differentially required by rice pattern recognition receptor （PRR） and resistance （R） protein-mediated immunity, and its function is likely dependent on the signaling pathway rather than the change of endogenous levels. Jasmonate （JA） plays an important role in rice basal defense against bacterial and fungal infection and may be involved in the SA-mediated resistance. Ethylene （ET） can act as a positive or negative modulator of disease resistance, depending on the pathogen type and environmental conditions. Brassinosteroid （BR） signaling and abscisic acid （ABA） either promote or defend against infection of pathogens with distinct infection/colonization strategies. Auxin and gibberellin （GA） are generally thought of as negative regulators of innate immunity in rice. Moreover, GA interacts antagonistically with JA signaling in rice development and immunity through the DELLA protein as a master regulator of the two hormone pathways. In this review, we summarize the roles of plant hormones in rice immunity and discuss their interplay/crosstalk mechanisms and the complex regulatory network of plant hormone pathways in fine-tuning rice immunity and growth.

This study aimed to explore the effect of fermented spent mushroom substrate(SMS) of Pleurotus eryngii as a basic material on rice seedling-raising substrate. The physical and chemical indices of the SMS indicated that the fermented SMS was fully composted and was very suitable for preparing rice seedling-raising substrate. The fermented SMS effectively regulated the bulk density, total porosity, aeration porosity and water-holding porosity of rice seedling-raising substrate. With the increased addition amount of fermented SMS, the bulk density of rice seedling-raising substrate was decreased, but the total porosity, aeration porosity and water-holding porosity were increased. Compared with those in the substrates of 100% soil and 100% SMS,the height, chlorophyll content, 100-shoot dry weight, 100-root dry weight, root activity, nitrogen content, phosphorus content and potassium content of rice seedlings in the substrate composed of spent mushroom substrate of P. eryngii and soil were *** quality of rice seedlings in the substrate composed of 20% soil and 80% SMS was best, followed by that in the substrate composed of 30% soil and 70% SMS.

Water stress is one of the major environmental stresses that affect agricultural production worldwide. Water loss from plants occurs primarily through stomatal pores. Here, we report that an Oryza sativa half-size ATP-binding cassette （ABC） subfamily G protein, RCN 1/OsABCG5, is involved in stomatal closure mediated by phytohormone abscisic acid （ABA） accumulation in guard cells. We found that the GFP-RCN1/ OsABCG5-fusion protein was localized at the plasma membrane in guard cells. The percentage of guard cell pairs containing both ABA and GFP-RCN1/OsABCG5 increased after exogenous ABA treatment, whereas they were co-localized in guard cell pairs regardless of whether exogenous ABA was applied. ABA application resulted in a smaller increase in the percentage of guard cell pairs containing ABA in rcnl mutant （A684P） and RCN1-RNAi than in wild-type plants. Furthermore, polyethylene glycol （drought stress）-inducible ABA accumulation in guard cells did not occur in rcnl mutants. Stomata closure mediated by exogenous ABA application was strongly reduced in rcnl mutants. Finally, rcnl mutant plants had more rapid water loss from detached leaves than the wild-type plants. These results indicate that in response to drought stress, RCN1/OsABCG5 is involved in accumulation of ABA in guard cells, which is indispensable for stomatal closure.
