Recently, ESG(Environmental, Social, Governance) has been recognized as an important factor for the sustainable growth of companies. However, only 14.5% of food manufacturing companies have adopted ESG management. In particular, small and medium-sized enterprises(SMEs) face difficulties in implementing ESG management due to a lack of specialized personnel and resource constraints. The purpose of this study is to analyze the impact of ESG ratings on the management performance of 40 food manufacturing companies listed on the Korea Exchange(KRX) that have been evaluated for ESG. The one-way ANOVA was used and performed on data for 40 food manufacturing companies published by the Korea Institute of Corporate Governance and Sustainability(KCGS) in 2023. The results of the analysis showed statistically significant differences in sales (F=12.936, p<0.001) and foreign ownership (F=7.74, p<0.01) based on ESG ratings. Furthermore, Scheffe's post-hoc analysis indicated that the higher the ESG rating and individual scores, the better the overall management performance. Therefore, it is concluded that food manufacturing companies should continuously invest in and focus on ESG management to secure a competitive advantage in the market and achieve sustainable growth.

Arabidopsis E3 SUMO ligase SIZ1 (AtSIZ1) controls vegetative growth and development including responses to nutrient deficiency and environment stresses. Here, we analyzed the effect of AtSIZ1 on the stability and amount of seed proteins. Proteomic analysis showed that the amount of three major nutrient reservoir proteins, CRUCIFERIN (CRU) 1, 2 and 3, were decreased in siz1-2 mutants. However, quantitative real-time RT-PCR showed that transcript levels of CRU1, 2 and 3 genes were rather significantly higher in siz1-2 mutants than wild-type plants. Yeast two hybrid analysis revealed that AtSIZ1 interacts with CRU1, CRU2 and CRU3, strongly suggesting that CRU1, 2 and 3 proteins are sumoylated by AtSIZ1. In addition, the analysis of amino acid composition by HPLC showed that the contents of amino acids were a bit high in siz1-2 mutants. Our data indicate that AtSIZ1 plays an important function for accumulation of seed storage proteins through its ligase activity.

Grain yield, one of the most important agronomic traits, is greatly affected by architecture in rice. Here, we show that an OsPrMC3, a rice PrMC3 orthologue with a lipase or esterase domain, involves in yielding by tillering. Phenotypic analysis of T-DNA insertion mutant revealed that it has high number of tillers than wild type although height and leaf width are shorter and narrower than wild type. Size and branch number of panicle were greatly reduced in the mutant, which resulted in significant decrease of seed number per panicle and dry weight of the seeds. OsPrMC3 is highly expressed in the leaf during the early stage of development. However, it is mainly expressed in mature seed and root after flowering although its expression is detected in all of the tissues. Our result indicates that OsPrMC3 involves in leaf growth and tillering during vegetative growth and also seed development after flowering, suggesting its crucial regulatory role in yielding
