Abstract:
... Iron (Fe) is a micronutrient for plant development, as constituent of several photosynthesis- and respiration-related proteins and enzymes. Consequently, Fe deficiency leads to chlorosis in leaves and plant growth impairment. It has become increasingly evident that light signals coordinate iron homeostasis in plants. To further address new insights into how light is a fundamental part of Fe defici ...

Abstract:
... Dopamine is a naturally occurring amine in plants and animals, having a strong antioxidative capacity. Different abiotic stressors, such as drought, salinity, and nutrient deficiency induce endogenous dopamine biosynthesis, while exogenous dopamine application confers tolerance to abiotic stress. Plants benefit from exogenous dopamine to promote photosynthetic pigment concentrations, stomatal cond ...

However, the role of morphological changes (e.g., colony size and tightness) in the adaptation to nutrient availability is not fully understood. In this study, we analyzed the morphological changes under both nutrient sufficiency and deficiency. Accordant morphological changes were found with both an isolated colonia ...

Abstract:
... Exogenous abscisic acid (ABA) could inhibit cadmium (Cd) accumulation in plants; however, its performance in an uneven iron (Fe) background remains unknown. Here, we found that the inhibitory effects of ABA on Cd accumulation in plants were optimal under nonlimiting Fe availability (25 and 50 µM), causing a reduction of 25–50 %, whereas only a 0–29 % decrease was observed in a Fe-free or -deficien ...

The micronutrient cycling in tropical latitudes is an issue of great concern because tropical soils are not only suffering micronutrient deficiency, but also influencing the global cycling of trace metals. With the development of stable isotope techniques, Zn isotopic composition (δ⁶⁶Zn) has been an powerful tool to interpret the Zn behaviour, signature, and cycling in soils. This review compiles ...

Abstract:
... Magic spot synthetases are emerging targets to overcome persistence caused by stringent response. The ‘stringent response’ is a bacterial stress survival mechanism, which results in the accumulation of alarmones (also called Magic spots) leading to the formation of dormant persister cells. These ‘sleeper cells’ evade antibiotic treatment and could result in relapse of infection. This review broadl ...
