Fungal Diversity and Gibberellin Hormones Associated with Long Whips of Smut-Infected Sugarcanes.

Sugarcane smut, caused by the fungus (Sydow), significantly affects sugarcane crops worldwide. Infected plants develop whip-like structures known as sori. Significant variations in these whip lengths are commonly observed, but the physiological and molecular differences causing these morphological differences remain poorly documented.
