Bioinformatic insights into sugar signaling pathways in sugarcane growth.

ABSTRACT: The SnRK1, hexokinase, and TORC1 (TOR, LST8, RAPTOR) are three pivotal kinases at the core of sugar level sensing, significantly impacting plant metabolism and development. We retrieved and analyzed protein sequences of these three kinase pathways from seven sugarcane transcriptome and genome datasets, identifying protein domains, phylogenetic relationships, sequence ancestry, and in silico expression levels. Additionally, we predicted HXK subcellular localization and assessed its enzymatic activity in sugarcane leaves and culms along development in the field. We retrieved 11 TOR, 23 RAPTOR, 55 LST8, 95 SnRK1α, 98 HXK, and 14 HXK-like putative full-length sequences containing all the conserved domains. Most of these transcripts seem to share a common origin with the three ancestral species
