Essentially, choline is an essential nutrient for plants and animals. It is an essential vitamin-like nutrient and is water soluble. It is not considered a vitamin or mineral. It refers to the class of quitrent ammonium salts containing the N, N, N trimethaloammonium salts. Role of Choline in animals: Say no to plagiarism.

Choline helps make fats and supports the cellular structure of cells. membrane.It helps in the transport of cholesterol from the liver and choline and other vitamins like B12 help in the synthesis of DNA.Role of choline in drought and salinity stress: Glycine betaine (GB) and praline are two major organic osmolytes found in a range of plants in response to environmental stresses such as heavy metal and UV reactions, as well as under salinity and drought conditions and temperature extremes such as very hot and very cold. Although their precise roles in plants remain controversial, both compounds are believed to have positive effects on the veracity of enzymes and membranes, as well as adaptive roles in managing osmotic changes in plants grown in a stress environment. Plant species diverge in their ability to make GB and some plants, such as spinach and barley, accumulate moderately high levels of GB in their chloroplasts while others, such as Arabidopsis and tobacco, do not produce this compound. . (CMO) means that Choline monooxygenase plays a catalytic role in the synthesis of glycine betaine. The (CMO) gene was introduced into cotton and has the ability to provide resistance to salinity stress. According to the present study, the two transgenic Ah Choline monooxygenases of cotton lines determine salinity nudity in greenhouse and field under salinity conditions. On average, GB are present 131% more in seedlings than in non-transgenic plants under normal salt stress conditions. As well as Ah Choline monooxygenase from cotton having the high tolerance of protecting the plant cell membrane and the photosynthesis capacity of transgenic plants as well as non-transgenic plants. Electrolyte leakage and osmotic potential are lower in transgenic plants as well as in non-transgenic plants. Under field stress and salinity conditions, the seed yield of transgenic plants is lower under normal conditions but higher than that of non-transgenic plants. Role of choline at hot temperature: Plant productivity is limited by high temperature. Early experiments showed that GB helped preserve certain enzymes and proteins from destabilization and heat. The increasing amount of GB can provide resistance to high temperatures. Transformed Arabidopsis joining GBs have tolerance during seed germination and imbibition, as well as seedling growth. It can protect the plant from heat waves. Role of choline at low temperature: GB supplied exogenously to plants can protect plants from stress caused by low temperatures. Arabidopsis, which gives rise to COD expression, can protect plants at low temperatures at different developmental stages from genetic engineering. During germination and imbibition, the seeds of transgenic plants.
