“…Bechtsis, Tsolakis, Vlachos, and Iakovou () argued that heavy financial penalties should be imposed on polluted logistical operations and vehicles for better environmental sustainability. Bektas et al () and Khan and Dong () emphasized the need of green practices and utilization of renewable energy in logistics and supply chain operations to control/mitigate harmful effects on environment and society.…”

This panel study investigates the relationship between green logistics indices, economic, environmental, and social factors in the perspective of Asian emerging economies. This study adopted Fully Modified OLS (FMOLS) Model and Dynamic OLS (DOLS) Model methods to test the research hypothesis, catering the problem of endogeneity and serial correlation. The results suggest that logistics operations, particularly LPI2 (efficiency of customs clearance processes), LPI4 (quality of logistics services), and LPI5 (trade and transport‐related infrastructure), are positively and significantly correlated with per capita income, manufacturing value added and trade openness, whereas greater logistics operations are negatively associated with social and environmental problems including, climate change, global warming, carbon emissions, and poisoning atmosphere. In addition, human health is badly affected by heavy smog, acid rainfall, and water pollution. The findings further extend and reveal that political instability, natural disaster, and terrorism are also a primary cause of poor economic growth and environmental sustainability with poor trade and logistics infrastructure. There is very limited empirical work presented in the literature using renewable energy and green ideology to solve macro‐level social and environmental problems, and this study will assist the policy makers and researchers to understand the importance of the green concept in improving countries' social, economic, and environmental performance.

“…The color is stable, and the resultant specimen can be stored for several days. To date, various studies have used this blue coloration as a trait for the screening of plant disease resistance elicitors 29,30 . JA signaling can be used as a marker pathway for the identification of synthetic chemical elicitors for the biological control of pests and diseases because of its crucial role in the regulation of plant defense 31,32 .…”

(E)-Nerolidol is a volatile signal that induces defenses against insects and pathogens in tea plants

et al. 2020

Plants release large amounts of volatile organic compounds (VOCs) in response to attackers. Several VOCs can serve as volatile signals to elicit defense responses in undamaged tissues and neighboring plants, but many questions about the ecological functions of VOCs remain unanswered. Tea plants are impacted by two harmful invaders, the piercing herbivore Empoasca (Matsumurasca) onukii Matsuda and the pathogen Colletotrichum fructicola. To determine the VOC signals in tea, we confirmed CsOPR3 as a marker gene and set up a rapid screening method based on a 1.51 kb CsOPR3 promoter fused with a β-glucuronidase (GUS) reporter construct (OPR3p::GUS) in Arabidopsis. Using this screening system, a terpenoid volatile (E)-nerolidol was identified as a potent signal that elicits plant defenses. The early responses triggered by (E)-nerolidol included the activation of a mitogen-activated protein kinase and WRKY, an H 2 O 2 burst, and the induction of jasmonic acid and abscisic acid signaling. The induced plants accumulated high levels of defenserelated chemicals, which possessed broad-spectrum anti-herbivore or anti-pathogen properties, and ultimately triggered resistance against Empoasca onukii and Colletotrichum fructicola in tea. We propose that these findings can supply an environmentally friendly management strategy for controlling an insect pest and a disease of tea plants.

“…This pattern resembles the concept of hormesis often deployed by toxicologists to describe the response to toxins, where exposure to a low dose is beneficial while a higher dose results toxicity due to overcompensation in response to disruption of homeostasis 53 . While tissue-specific hormetic responses have been described in flies, where a virus-acquired cytokine relays ageing 54 , and examples of abiotic factors or signalling molecules affecting peas and aphid infestation 55 , immunity in plants 56,57 , life-span in malaria-transmitting Anopheles 58 , and larval development in Black Cutworm 59 , this example here could be the first involving a eukaryotic host-pathogen relationship. The underlying factor remains to be elucidated but C. neoformans ’ highly immunogenic capsule seems to be an excellent candidate 48 .…”

29Pathogenic yeast species can cause life-threatening infections in humans. The two leading 30 yeast pathogens, Candida albicans and Cryptococcus neoformans, cause systemic infections 31 in >1.4 million patients world-wide with mortality rates approaching 75%. It is thus 32 imperative to study fungal virulence mechanisms, stress response pathways, and the efficacy 33 of antifungal drugs. This is commonly done using mammalian models. To address ethical and 34 practical concerns, invertebrate models, such as wax moth larvae, nematodes, or flies, have 35 been introduced over the last two decades. To address short-comings in existing invertebrate 36 host models, we developed fifth instar caterpillars of the Tobacco Hornworm moth Manduca 37 sexta as a novel host model for the study of fungal virulence and drug efficacy. These 38 caterpillars can be raised at standardised conditions, maintained at 37˚C, can be injected with 39 defined amounts of yeast cells, and are susceptible to the most threatening yeast pathogens, 40 including C. albicans, C. neoformans, C. auris, and C. glabrata. Infected caterpillars can be 41 rescued by treatment with commonly deployed antifungal drugs and importantly, fungal 42 burden can be assessed daily throughout the course of infection in a single caterpillar's faeces 43 and hemolymph. Notably, these animals are large enough so that weight provides a reliable 44 and reproducible measure of fungal virulence. This model combines a suite of parameters that 45 recommend it for the study of fungal virulence. 46 47 50 tuberculosis 1 . The leading yeast pathogens, Candida albicans and Cryptococcus neoformans, 51 together account for >1,400,000 life-threatening infections world-wide with mortality rates 52 approaching 75% 1 . Candidemia, most commonly caused by C. albicans, is the fourth most 53 common cause of nosocomial blood stream infections, only surpassed by infections with 54Staphylococci and Enterococcus spp. Disturbingly, candidemia incidence rates are on the 55 rise. Within less than ten years, incidence rates increased by 36% 2 . Although cryptococcosis 56 incidence rates are on the decline in North America, this AIDS-defining illness is responsible 57 for 15% of all AIDS-related deaths world-wide 2,3 . This already dire situation is further 58 confounded by the emergence of drug resistant yeast species. Patients at risk of developing 59 invasive candidemia are often prophylactically treated with fluconazole, while the 60 echinocandins are considered a first line defence strategy 4 . Yet, C. glabrata, the most 61 3 common non-albicans Candida species associated with nosocomial blood stream infections 5 , 62 is intrinsically less susceptible to azole drugs and acquires resistance to echinocandins 63 rapidly 6 . The rapid global spread of multi-drug resistant C. auris has further exacerbated the 64 threat posed by fungi. C. auris was first reported in 2009 in Japan 7 . In 2015, C. auris arrived 65 in Europe causing an outbreak involving 72 patients in a cardio-thoracic hospital i...
