Many discoveries in science have been accidental. This is true for plant hormones also. Can you justify this statement by giving an example? Also,what term is used for such accidental findings?

(N/A) The discovery of the plant hormone $Gibberellins$ was made by chance. It happened in rice fields where some rice plants were observed to be unusually taller than the normal ones.
Scientific investigation revealed that these plants were infected with a fungus known as $Gibberella$ $fujikuroi$.
This fungus releases the plant hormone $Gibberellic$ $acid$ $(GA)$ in excess concentrations,which causes the plant to grow unusually tall.
The term used for such accidental findings is $Serendipity$,which means a fortunate happenstance. It was coined by $Horace$ $Walpole$ in $1754$. He defined it as making discoveries by accident and sagacity.
