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. The progression of an organism from an initial condition to a later condition, occurring when the organism is in a symbiotic interaction. The assembly by the symbiont of a threadlike, tubular structure, which may contain multiple nuclei and may or may not be divided internally by septa or cross-walls, for the purpose of penetration into its host organism. In the case of an appressorium existing, this term is defined in further details as the process by which the symbiont penetration peg expands to form a hypha which traverses the epidermal cell and emerges into the intercellular space of the mesophyll tissue. 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 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 development of a swollen tip at the growing end of a symbiont spore which usually flattens against the host cell surface prior to appressorium formation. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process by which an organized mass of hyphae is formed on or near the host organism, and numerous infective hyphae develop from the hyphae mass. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process by which a symbiont cell is formed on or near its host organism, via separated from the tip of an infection hypha by a septum. The haustorium mother cell usually contains 2-4 fungal nuclei, and its function is to attach and penetrate the host. The host is defined as the larger of the organisms involved in a symbiotic interaction. The process by which anatomical structures are generated and organized. Morphogenesis pertains to the creation of form. The assembly by the symbiont of a neck-like structure for the purpose of penetration into its host organism. The neck-like structure connects haustorium mother cell and haustorium. The host is defined as the larger of the organisms involved in a symbiotic interaction. A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition. The process by which a specialized structure, consisted of stalked, thick-walled, lobed cells of vegetative epiphytic hyphae, is formed, to attach and penetrate the host surface. The host is defined as the larger of the organisms involved in a symbiotic interaction. The assembly by the symbiont of a peg-like structure for the purpose of penetration into its host organism, which penetrates through the host cuticle and epidermal cell wall. 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.
