The progression of an organism from an initial condition to a later condition, occurring in, on or near the exterior of its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. Any process that modulates the frequency, rate or extent of symbiont appressorium formation on or near its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process whereby specialized features of the symbiont appressorium are acquired post initiation, to aid in infection of the host. The host is defined as the larger of the organisms involved in a symbiotic interaction. Any process that activates or increases the frequency, rate or extent of symbiont appressorium formation on or near its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process by which a symbiont structure that serves to infect the host is formed on or near its host organism. It includes physiological, developmental, and morphological changes of the symbiont. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process by which a symbiont partition is formed to separate the appressorium from the germination tube, occurring on or near the exterior of its host organism during appressorium formation. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process by which a swollen, flattened portion of a symbiont filament is formed on or near its host organism, to adhere to and for the purpose of penetrating the host surface. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process whereby a relatively unspecialized cell starts to acquire specialized features of the symbiont appressorium to aid in infection of the host. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process by which nuclear division occurs within a symbiont spore during appressorium formation on or near the exterior of its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. The progression of the symbiont from an initial condition to a later condition, occurring on or near its host phyllosphere. The host phyllosphere is defined as total above-ground surfaces of a plant as a habitat for symbiont. The host is defined as the larger of the organisms involved in a symbiotic interaction. Any process that stops, prevents or reduces the frequency, rate or extent of symbiont appressorium formation on or near its host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. The developmental process pertaining to the initial formation of an anatomical structure from unspecified parts. This process begins with the specific processes that contribute to the appearance of the discrete structure and ends when the structural rudiment is recognizable. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. The process by which a symbiont spore digests parts of its own cytoplasm, occurring when the appressorium forms on or near the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. The progression of a symbiont from an initial condition to a later condition, within the cells or tissues of its host organism.
