The multidimensional regulation roles and mechanisms of calcium in fruit quality
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

Hyperphenylalaninemia and serotonin deficiency in Dnajc12-deficient mice
Serotonin exerts numerous neurological and physiological actions in the brain and in the periphery. It is generated by two different tryptophan hydroxylase enzymes, TPH1 and TPH2, in the periphery and in the brain, respectively, which are members of the ...

ABSTRACT Plant viruses are so harmful to crops. It is an urgent need to develop modern, environment‐friendly, and sustainable plant viral epidemic‐management strategies that are safe for both human health and the environment. The field of nanotechnology is gaining increased interest in plant science.

ABSTRACT Flower colour variation is pivotal for plant evolution, ecological adaptation, and pollinator attraction. In the Liriodendron genus, L. tulipifera features a distinct orange petal stripe which is absent in L. chinense, driven by differential carotenoid accumulation, yet the underlying genetic mechanism remains unclear.

High Protein Diet and Phenylalanine Hydroxylase Activities in Rats
The effects of a diet of 85% casein on the activities of the phenylalanine hydroxylases of rat liver and kidney have been compared. Whereas only the tetrahydrobiopterin-dependent activity of rat hepatic phenylalanine hydroxylase is significantly ...

Allosteric regulation of phenylalanine hydroxylase [PDF]
The liver enzyme phenylalanine hydroxylase is responsible for conversion of excess phenylalanine in the diet to tyrosine. Phenylalanine hydroxylase is activated by phenylalanine; this activation is inhibited by the physiological reducing substrate tetrahydrobiopterin.

Convergent Evolution and De Novo Reconstitution of Apiin Biosynthesis
ABSTRACT Apiin, an active flavonoid apioside, occurs in phylogenetically distant plants, such as parsley and chilli pepper (Capsicum annuum L.). Its sporadic distribution suggests the existence of convergent apiin biosynthesis; however, the molecular mechanisms underlying this convergence remain unclear.
