What does PST mean?

Puccinia Striiformis f.sp. Tritici (PST) is a fungal pathogen that causes yellow (stripe) rust, a serious disease in wheat crops.
Stripe rust, as the name implies, causes yellow or orange stripes to appear on the leaves of infected plants.

Note:
The abbreviation f.sp. stands for "forma specialis," which is a taxonomic rank used in plant pathology to designate subspecies or varieties of fungi that are specialized to infect a particular host plant species or group of related plant species.
In the case of Puccinia striiformis f.sp. tritici, "tritici" refers to wheat, indicating that this particular form of the fungus is specialized to infect wheat plants.
