Abstract
Bacterial secondary metabolites are a valuable source of various molecules that have antibacterial and anticancer activity. In this study, ten endosymbiotic bacteria of aphids, aphid predators and ants were isolated. Bacterial strains were identified according to the 16S rRNA gene. Ethyl acetate fractions of methanol extract (EA-ME) were prepared from each isolated bacterium and tested for their antibacterial activities using the disk diffusion method. The EA-ME of three bacterial species, Planococcus sp., Klebsiella aerogenes, Enterococcus avium, from the pomegranate aphids Aphis punicae, Chrysoperia carnea, and Tapinoma magnum, respectively, exhibited elevated antibacterial activity against one or several of the five pathogenic bacteria tested. The inhibition zones ranged from 10.00 ± 0.13 to 20.00 ± 1.11 mm, with minimum inhibitory concentration (MIC) values ranging from 0.156 mg/mL to 1.25 mg/mL. The most notable antibacterial activity was found in the EA-ME of K. aerogenes against Klebsiella pneumonia and Escherichia coli, with an MIC value of 0.156 mg/mL. The cytotoxic activity of EA-ME was dependent on the cell line tested. The most significant cytotoxicity effect was observed for extracts of K. aerogenes and E. avium, at 12.5 µg/mL, against the epithelial cells of lung carcinoma (A549), with a cell reduction of 79.4% and 67.2%, respectively. For the EA-ME of K. aerogenes and Pantoea agglomerans at 12.5 µg/mL, 69.4% and 67.8% cell reduction were observed against human colon cancer (Hct116), respectively. Gas chromatography-mass spectrometry (GC-MS) analysis of three EA-ME revealed the presence of several bioactive secondary metabolites that have been reported previously to possess antibacterial and anticancer properties. To the best of our knowledge, this is the first study to examine the biological activities of endosymbiotic bacteria in aphids, aphid predators and ants. The promising data presented in this study may pave the way for alternative drugs to overcome the continued emergence of multidrug-resistant bacteria, and find alternative drugs to conventional cancer therapies.

SH3P2, an SH3 domain-containing protein that interacts with both Pib and AvrPib, suppresses effector-triggered, Pib-mediated immunity in rice. Mol Plant 2022; 15:1931-1946.

Abstract
Plants usually keep resistance (R) proteins in a static state under normal conditions to avoid autoimmunity and save energy for growth, but R proteins can be rapidly activated upon perceiving pathogen invasion. Pib, the first cloned blast disease R gene in rice, encoding a nucleotide-binding leucine-rich repeat (NLR) protein, mediates resistance to the blast fungal (Magnaporthe oryzae) isolates carrying the avirulence gene AvrPib. However, the molecular mechanisms about how Pib recognizes AvrPib and how it is inactivated and activated remain largely unclear. In this study, through map-based cloning and CRISPR-Cas9 gene editing, we proved that Pib contributes to the blast disease resistance of rice cultivar Yunyin (YY). Furthermore, an SH3 domain-containing protein, SH3P2, was found to associate with Pib mainly at clathrin-coated vesicles in rice cells, via direct binding with the coiled-coil (CC) domain of Pib. Interestingly, overexpression of SH3P2 in YY compromised Pib-mediated resistance to M. oryzae isolates carrying AvrPib and Pib-AvrPib recognition-induced cell death. SH3P2 competitively inhibits the self-association of the Pib CC domain in vitro, suggesting that binding of SH3P2 with Pib undermines its homodimerization. Moreover, SH3P2 can also interact with AvrPib and displays higher affinity to AvrPib than to Pib, which leads to dissociation of SH3P2 from Pib in the presence of AvrPib. Taken together, our results suggest that SH3P2 functions as a "protector" to keep Pib in a static state by direct interaction during normal growth but could be triggered off by the invasion of AvrPib-carrying M. oryzae isolates. Our study reveals a new mechanism about how an NLR protein is inactivated under normal conditions but is activated upon pathogen infection.

Abstract
Amyotrophic lateral sclerosis (ALS) is an incurable chronic progressive neurodegenerative disease with the progressive degeneration of motor neurons in the motor cortex and lower motor neurons in the spinal cord and the brain stem. The etiology and pathogenesis of ALS are being actively studied, but there is still no single concept. The study of ALS risk factors can help to understand the mechanism of this disease development and, possibly, slow down the rate of its progression in patients and also reduce the risk of its development in people with a predisposition toward familial ALS. The interest of researchers and clinicians in the protective role of nutrients in the development of ALS has been increasing in recent years. However, the role of some of them is not well-understood or disputed. The objective of this review is to analyze studies on the role of nutrients as environmental factors affecting the risk of developing ALS and the rate of motor neuron degeneration progression. METHODS We searched the PubMed, Springer, Clinical keys, Google Scholar, and E-Library databases for publications using keywords and their combinations. We analyzed all the available studies published in 2010-2020. DISCUSSION We analyzed 39 studies, including randomized clinical trials, clinical cases, and meta-analyses, involving ALS patients and studies on animal models of ALS. This review demonstrated that the following vitamins are the most significant protectors of ALS development: vitamin B12, vitamin E > vitamin C > vitamin B1, vitamin B9 > vitamin D > vitamin B2, vitamin B6 > vitamin A, and vitamin B7. In addition, this review indicates that the role of foods with a high content of cholesterol, polyunsaturated fatty acids, urates, and purines plays a big part in ALS development. CONCLUSION The inclusion of vitamins and a ketogenic diet in disease-modifying ALS therapy can reduce the progression rate of motor neuron degeneration and slow the rate of disease progression, but the approach to nutrient selection must be personalized. The roles of vitamins C, D, and B7 as ALS protectors need further study.
