hey buddy here's ur answer↩↩↩↩↩

A model organism is a non-human speciesthat is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms.

ADVANTAGE of physcomitrella patens as a modern organism

⏹The moss Physcomitrella patens has a great potential as a model system to perform functional studies of plant interacting with microbial pathogens. P. patens is susceptible to fungal and oomycete infection, which colonize and multiply in plant tissues generating disease symptoms. In response to infection, P. patens activates defense mechanisms similar to those induced in flowering plants, including the accumulation of reactive oxygen species, cell death with hallmarks of programmed cell death, cell wall fortification, and induction of defense-related genes like PAL, LOX, CHS, and PR-1. 

⏹1. Activation of Plant Defense Mechanisms against Pathogens

➡ The effectiveness of this response relies on the ability to recognize the invading pathogen and to mount rapidly a host defense response that includes cell wall fortification, release of reactive oxygen species (ROS), induction of hypersensitive response (HR), and accumulation of phytoalexins and enzymes that degrade fungal cell walls, as well as other proteins involved in defense .

➡ Defense hormones such as salicylic acid (SA), jasmonates, and ethylene play key roles in regulating many of these host reactions to pathogen assault and modulation of additional hormonal pathways contribute to disease resistance [4, 6].

⏹2. Interaction of Mosses with Fungal Pathogens in Nature

➡ The fungal penetration process into moss tissues, as well as cell disruption and some host responses including the deposition of darkly pigmented material in the cell wall (papillae), was described for some of these pathogens [11, 14–16]. The penetration of host cells by bryophilous pathogens involves vegetative hyphae, penetration pegs and sometimes appressorium, and enzymatic digestion of the plant cell wall [13, 15].
