ABSTRACT
Leaves are the primary and critical feed for herbivores. They directly determine the yield and quality of legume forage. <i>Trifolium repens</i> (<i>T. repens</i>) is an indispensable legume species, widely cultivated in temperate pastures due to its nutritional value and nitrogen fixation. Although the leaves of <i>T. repens</i> are typical trifoliate, they have unusual patterns to adapt to herbivore feeding. The number of leaflets in <i>T. repens</i> affects its production and utilization. The <i>KNOX</i> gene family encodes transcriptional regulators that are vital in regulating and developing leaves. Identification and characterization of <i>TrKNOX</i> gene family as an active regulator of leaf development in <i>T. repens</i> were studied. A total of 21 <i>TrKNOX</i> genes were identified from the T. repens genome database and classified into three subgroups (Class I, Class II, and Class M) based on phylogenetic analysis. Nineteen of the genes identified had four conserved domains, except for <i>KNOX5</i> and <i>KNOX9</i>, which belong to Class M. Varying expression levels of TrKNOX genes were observed at different developmental stages and complexities of leaves. <i>KNOX9</i> was observed to upregulate the leaf complexity of T. repens. Research on <i>TrKNOX</i> genes could be novel and further assist in exploring their functions and cultivating high-quality <i>T. repens</i> varieties.
