The role that strigolactones play in the growth of the plant. The relationship between the experiment conducted and the fact that strigolactones act as signals for parasitic plants and arbiscules. Introduction: Plant growth is regulated at many levels by plant hormones. These molecules act as signals and are required in low concentrations. Every phase of plant life, be it germinations or flowering or fruiting or senescence is governed by these signaling molecules. Strigolactones refer to the group of plant hormones, which play an essential role in the plants. Arabidopsis plant mutated for a strigolactone gene has a bushy shoot structure. If strigolactones are applied to the plant, normal growth is achieved.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

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…
