How does the environment affect genetic factors and gene expression and environmental factors that can influence gene expression plants?
Environmental factors such as soil nutrients, temperature, water availability and light intensity influence the genetic and chemical diversity of plant populations. These environmental conditions can exert strong selection pressures; they could even determine the evolutionary course of plant populations. Gene expression can be altered by environmental factors such as food, drugs or exposure to toxins. These changes can range from small to so significant that certain genes in our system can be turned off or on when they are supposed to be the opposite way. Environmental factors such as soil nutrients, temperature, water availability and light intensity influence the genetic and chemical diversity of plant populations. Genetic factors as well as local conditions affect the growth of an adult plant. The growth of an animal is controlled by genetic factors, food intake, and interactions with other organisms and each species have a typical adult size range. Primary abiotic factors are light, temperature, water, atmospheric gases, and ionizing radiation, influencing the form and function of the individual. For each environmental factor, an organism has a tolerance range in which it is able to survive.

Environmental factors such as soil nutrients, temperature, water availability and light intensity influence the genetic and chemical diversity of plant populations. These environmental conditions can exert strong selection pressures; they could even determine the evolutionary course of plant populations. Sometimes the environment changes a gene either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits. Some harmful environmental factors can change a gene's nucleotide sequence. Gene expression can be altered by environmental factors such as food, drugs or exposure to toxins, according to Duke Magazine. These changes can range from small to so significant that certain genes in our system can be turned off or on when they are supposed to be the opposite way. Subtle differences in one person's genes can cause them to respond differently to the same environmental exposure as another person. As a result, some people may develop a disease after being exposed to something in the environment while others may not. Epigenetic serves as a link between the environment and gene expression. Epigenetics refers to a set of reversible heritable changes that occur without a change in DNA sequence.
