What is the significance of yellow corn to farmers?4 answersYellow corn is significant to farmers because it serves as the basis for the poultry industry and is a highly demanded food by consumers. In Peru, yellow corn provides 40% of the grain required by the poultry industry, supporting local farmers and contributing to food production. In the Philippines, yellow corn is a major crop in Isabela, where farmers rely on traditions and superstitions for farming decisions. However, with the progression of climate change, technology is needed to provide advice to farmers, and a Smarter Agriculture solution has been developed to help yellow corn farmers make informed decisions about planting, harvesting, and water management. Yellow corn also has variations in its chemical composition, such as variations in oil content and the presence of fat-soluble vitamins, which have been found to have an impact on animal growth and weight gain. Additionally, the cultivation of yellow corn has been a determining factor in the development of the Mexican agricultural sector, although the free trade of American corn has posed challenges for Mexican farmers.
Why are leaves turning yellow?5 answersLeaves turn yellow due to the loss of chlorophyll and the degradation of macromolecules during leaf senescence. Leaf senescence is primarily regulated by plant age, but it can also be influenced by factors such as phytohormones and environmental stimuli. The catabolism of chlorophyll plays a significant role in leaf yellowing, and the breakdown of chlorophyll is regulated by the expression of Pheide a oxygenase (PaO). The retention of chlorophyll and apoproteins in the thylakoids can occur in stay-green mutants with a deficiency in the catabolic system. Additionally, the changes in leaf spectra and the development of a yellow color are related to the changes in light penetration during chlorophyll breakdown. The regreening of leaves in advanced stages of yellowing is governed by molecular processes and signals, including the role of plant hormones, particularly cytokinins.
What are the implications of having insects attracted to yellow?5 answersInsects being attracted to yellow can have several implications. One implication is that yellow stimuli can influence the orientation behavior of insects, even in species where visual cues are assumed to be unimportant. This suggests that visual stimuli, including the color yellow, play a role in insect behavior and orientation. Additionally, the preference for yellow stimuli may be related to the coloration of host leaves, as observed in psyllids and aphids. In some cases, the preference for yellow may be associated with the color preference of flies, which are common pollinators in certain environments. Overall, the attraction of insects to yellow stimuli highlights the importance of visual cues in insect behavior and the potential ecological implications of color preferences in different insect taxa.
Why quinone are yellow?4 answersQuinones are yellow because of their chemical structure and the presence of certain functional groups. The yellow color of quinoline yellow (QY) is due to its synthetic nature and its use as a coloring agent in foodstuffs. A novel quinone-modified graphene material, anthraquinone-2-sulfonic acid (AQS)-modified RGO (AQS-RGO), was found to enhance the catalytic performance of graphene for the decolorization of azo dye Acid Yellow 36 (AY 36). Mushroom tyrosinase and quinone isomerase were used to investigate the biosynthesis of papiliochrome II pigment found in the yellow scales of papilionid butterflies. Quinacridonequinone is rendered lightfast by the provision of a solid solution with essentially colorless 6,13-dihydroquinacridone. A yellow-type reduced pyrroloquinoline quinone crystal has a solubility in water of 0.040-0.20 (mg/ml).
