The noble gases are left out of the trends in atomic radii because there is great debate over the experimental values of their atomic radii.

The SI units for measuring atomic radii are the nanometer (nm) and the picometer (pm). 1 nm = 1 X 109 m; 1 pm = 1 X 10-12 m.

Necrotrophs are Opportunistic, unspecialised (‘non-obligate’) pathogens and Host cells killed rapidly

Entry unspecialised via wounds or natural openings

Secrete copious cell-wall-degrading (lytic) enzymes and toxins

Appressoria/haustoria not normally produced

Wide host range

Easy to culture axenically

Survive as competitive saprotrophs

Controlled by jasmonate- and ethylene-dependent host-defence pathways
