Small ubiquitin-like modifier(SUMO)-conjugating enzymes are involved in post-translational regulatory processes in eukaryotes, including the conjugation of SUMO peptides to protein substrate(SUMOylation). SUMOylation plays an important role in improving plant tolerance to abiotic stress such as salt, drought, heat and cold. Herein, we reported the isolation of OsSCE1(LOC_Os10 g39120) gene encoding a SUMO-conjugating enzyme from rice(Oryza sativa cv. Nipponbare) and its functional validation in response to drought stress. The E2 enzyme, Os SCE1, is one of three key enzymes involved in the conjugation of SUMO to its target proteins. Activated SUMO is transferred to the cysteine of an E2 enzyme and then to the target lysine residue of the substrate, with or without the help of an E3 SUMO ligase. Expression of OsSCE1 was strongly induced by polyethylene glycol 6000(PEG6000) treatment, which suggested OsSCE1 may be involved in the drought stress response. Overexpression of OsSCE1(OsSCE1-OX) in Nipponbare reduced the tolerance to drought stress. Conversely, the drought tolerance was slightly improved by the knockdown of OsSCE1(OsSCE1-KD). These results were further supported by measurement of proline content in OsSCE1-OX and OsSCE1-KD transgenic lines under induced drought stress, which showed OsSCE1-KD transgenic lines accumulated higher proline content than the wild type, whereas OsSCE1-OX line had lower proline content than the wild type. These findings suggested OsSCE1 may play a role as a negative regulator in response to drought stress in rice.

The previous studies have shown that capital market integration has increased in the ASEAN-5,implying that investors making investment diversification across ASEAN capital markets could only earn limited diversification *** diversify their portfolios,equity investors must find other *** main focus of this research is to analyze the effectiveness of put replication,gold,and oil on hedge equities in the ASEAN-5(Indonesia,Malaysia,Singapore,Thailand,and the Philippines).Protective put strategy,DCC-GARCH,and Markowitz optimization are used to measure hedge effectiveness,risk-adjusted-performance such as Sharpe ratio,drawdown,and Omega *** result reveals that gold is a cheaper hedge than oil and oil-hedged strategy is more expensive in ASEAN-5 compared to oil exporting ***,investors with big exposure to the oil-related portfolio should diversify to Philippine *** hedging effectiveness and risk-adjusted-performance perspectives,oil is less attractive than money market instruments and *** study also implies that risk-averse investors should prefer to put replication or guaranteed financial products compared to commodities-hedged strategy.
