The different methods in which chemical signals that reach the plant cells get converted into cell functions. Introduction: The phytohormones are small chemical compounds, which regulate the growth, flowering and metabolic activities of the plants. The plant hormones like auxin, cytokinins, and gibberellins promote the growth of plant parts, whereas abscisic acid inhibits the growth of plant parts. These hormones bind to receptors that initiate the signaling cascade leading to the activation of certain genes inside the nucleus of the cell. The receptors of the hormones may be present inside or on the cell membrane.

Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
