The present work aimed at investigating changes in growth and some metabolic activities in NaCl-stressed bean plants, and assessing the role of ascorbic acid to alleviate these changes. The field experiment was carried out to study the response of presoaked fava bean seeds (Vicia fava cv. Misr 2) in freshly prepared ascorbic acid (50 ppm ≈ 0.3 mM; as recommended dose as described by  El-Tayeb, ...

However, traditional production approaches source-dependent generally subject low contents target pigment compounds. order scale-up industrial production, ma...

HE red and brown eye pigments of Drosophila melanogaster are different T in their properties and developmental history. The formation of the brown pigment depends on diffusible substances derived from tryptophane; that of the red pigment apparently does not. Hence, a t least the final stages of the reaction chains leading to the formation of these pigments follow different paths. However, some ...
