Nitric oxide (NO) is a key signaling molecule in plant physiology. However, its production in
photosynthetic organisms remains partially unresolved. The best characterized NO …

The chemical species involved in H2S signaling remain elusive despite the profound and
pleiotropic physiological effects elicited by this molecule. The dominant candidate …

The importance of selenium (Se) for medicine, industry and the environment is increasingly
apparent. Se is essential for many species, including humans, but toxic at elevated …

Growth of eukaryotic cells is regulated by the target of rapamycin (TOR). The strongest
activator of TOR in metazoa is amino acid availability. The established transducers of amino …

Sulfur is essential in all organisms for the synthesis of amino acids cysteine and methionine
and as an active component of numerous co-factors and prosthetic groups. However, only …

Abstract Background Selenium (Se) is a micronutrient required for many life forms, but toxic
at higher concentration. Plants do not have a Se requirement, but can benefit from Se via …

Sulfur (S) is an essential plant macronutrient and the pivotal role of sulfur compounds in
plant disease resistance has become obvious in recent decades. This review attempts to …

The pathway of sulfate assimilation, which provides plants with the essential nutrient sulfur,
is tightly regulated and coordinated with the demand for reduced sulfur. The responses of …

Sulfur dioxide (SO2) are a category of chemical compounds widely used as additives in food
industry. So far, the use of SO2 in fruit and vegetable industry has been indispensable …

Dwindling water resources combined with meeting the demands for food security require
maximizing water use efficiency (WUE) both in rainfed and irrigated agriculture. In this …
