Abstract:
... Microbial cell factories provide vital platforms for the production of chemicals. Advanced biotechnological toolboxes have been developed to enhance their efficiency. However, these tools have limitations in improving physiological functions, and therefore boosting the efficiency (e.g. titer, rate, and yield) of microbial cell factories remains a challenge. In this review, we propose a strategy of ...

Abstract:
... Animals and plants are metaorganisms and associate with microbes that affect their physiology, stress tolerance, and fitness. Here the hypothesis that alteration of the microbiome may constitute a fast‐response mechanism to environmental change is examined. This is supported by recent reciprocal transplant experiments with reef corals, which have shown that their microbiome adapts to thermally var ...

Abstract:
... Melatonin (N‐acetyl‐5‐methoxytryptamine) plays important roles in plant defences against a variety of biotic and abiotic stresses, including UV‐B stress. Molecular mechanisms underlying functions of melatonin in plant UV‐B responses are poorly understood. Here, we show that melatonin effect on molecular signalling pathways, physiological changes and UV‐B stress resistance in Arabidopsis. Both exog ...

Abstract:
... In plants, auxin and ABA play significant roles in conferring tolerance to environmental abiotic stresses. Earlier studies have been shown that some Aux/IAA genes, with important signaling factors in the auxin pathway, were induced in response to drought and other abiotic stresses. However, the mechanistic links between Aux/IAA expression and general drought response remain largely unknown. In thi ...

Abstract:
... The success of Salmonella as a foodborne pathogen can probably be attributed to two major features: its remarkable genetic diversity and its extraordinary ability to adapt. Salmonella cells can survive in harsh environments, successfully compete for nutrients, and cause disease once inside the host. Furthermore, they are capable of rapidly reprogramming their metabolism, evolving in a short time f ...

Abstract:
... Climate change is related to an increase in frequency and intensity of extreme events such as heatwaves. It is well established that such events may worsen the current world‐wide biodiversity decline. In many organisms, heat stress is associated with direct physiological perturbations and could lead to a decrease of fitness. In contrast to endotherms, heat stress resistance has been poorly investi ...

Abstract:
... The toxicity of Cr(VI) was widely investigated, but the defense mechanism against Cr(III) in bacteria are seldom reported. Here, we found that Cr(III) inhibited bacterial growth and induced reactive oxygen species (ROS). After exposure to Cr(III), loss of sodA not only led to the excessive generation of ROS, but also enhanced the level of lipid peroxidation and reduced the GSH level, indicating th ...

The importance of microorganisms in plant development, nutrition, and stress resistance is unquestioned and has led to a more holistic approach of plant–microbe interactions, under the holobiont concept. The structure of the plant microbiota is often described as host driven, especially in the rhizosphere, where microbial communities are shaped by diverse rhizodeposits. Gradually, this anthropogen ...
