Green innovation has become the main path toward achieving corporate sustainable development. Despite the centrality of organizational learning in firms pursuing green activities, little research has considered its role in the relationship between stakeholder pressures and green innovation. By combining stakeholder theory and organizational learning theory, this study explores whether environmental pressures from different stakeholders influence green innovation differently and how this is further mediated by organizational learning. From a sample of 259 Chinese manufacturing firms, we find that consumer pressure has a greater positive effect on green product innovation than regulation pressure, whereas regulation pressure is more positively related to green process innovation than consumer pressure. Moreover, these two relationships are partially mediated by exploration learning and exploitation learning, respectively. These findings advance the existing research on the stakeholder pressures-green innovation linkage by revealing that consumer and regulation pressures influence green product innovation and green process innovation differently and through different organizational learning approaches.
Diterpenoids are the major group of antimicrobial phytoalexins in rice 1,2 . Here we report the discovery of a rice diterpenoid gene cluster on chromosome 7 (DGC7) encoding the entire biosynthetic pathway to 5,10-diketo-casbene, a member of the mono-cyclic casbene-derived diterpenoids. We revealed that DGC7 is regulated through MeJA mediated epigenetic control directly by JMJ705 3 . Functional characterization of pathway genes revealed OsCYP71Z21 to encode a casbene C10 oxidase, sought after for the biosynthesis of an array of medicinally important
Myostatin (MSTN), also referred to as growth and differentiation factor-8, is a protein secreted in muscle tissues. Researchers believe that its primary function is in negatively regulating muscle because a mutation in its coding region can lead to the famous double muscle trait in cattle. Muscle and adipose tissue develop from the same mesenchymal stem cells, and researchers have found that MSTN is expressed in fat tissues and plays a key role in adipogenesis. Interestingly, MSTN can exert a dual function, either inhibiting or promoting adipogenesis, according to the situation. Due to its potential function in controlling body fat mass, MSTN has attracted the interest of researchers. In this review, we explore its function in regulating adipogenesis in mammals, including preadipocytes, multipotent stem cells and fat mass.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
