| description | In plants, <i>SPL</i> is a distinct family of transcription factors. Its protein structure possesses a highly conserved SBP domain comprising two zinc finger structures and nuclear localization regions, and microRNAs (miR156) control the transcriptional expression of the majority of <i>SPL</i> genes. <i>SPLs</i> are key TFs in regulating organ morphogenesis, phase transition/floral induction, and yield-related traits in agronomic and horticultural crops. These biomolecules have been functionally characterized for their role in augmenting plant responses to abiotic and biotic stresses. Present research gaps and viewpoints are addressed herein. Using these extensive data, researchers can more comprehensively understand how <i>SPL</i> genes modulate agronomic features in different ways. |
