Gibberellinae

Gibberellinae is a subtribe of fungi within the order Hypocreales. Members of this group are primarily known for their association with plants and include a variety of species, some of which are plant pathogens. The subtribe is characterized by certain morphological and genetic features that distinguish it from other fungal groups.

A notable characteristic of some Gibberellinae species is their ability to produce plant hormones, specifically gibberellins. These compounds play a crucial role in plant growth and development, influencing processes such as stem elongation, seed germination, and flowering. The discovery and understanding of gibberellins were significantly advanced by research on fungi in this subtribe.

While some Gibberellinae are saprophytic, meaning they decompose dead organic matter, others are endophytes, living within plant tissues without causing immediate harm. However, a subset of these fungi are virulent pathogens, capable of causing diseases in a wide range of crops. These diseases can manifest in various ways, including wilts, blights, and spots, leading to significant agricultural losses. Research into the pathogenicity mechanisms and control strategies for these fungal diseases is ongoing. The phylogenetic relationships within Gibberellinae are continually being refined through molecular studies, aiding in the classification and understanding of this diverse fungal group.
