Phylogeny and Expression Atlas of the in Agave.

species are widely cultivated crassulacean acid metabolism (CAM) plants for alcoholic beverages, food and fiber production. Among these, the hybrid H11648 (( × ) × ) is the main cultivar for sisal fiber in the tropical areas of Brazil, China, and African countries. The plants of hybrid H11648 have a long life cycle and large leaves, which require a huge amount of nitrogen nutrient. However, the molecular basis of nitrogen transport and allocation has not been well understood in agave. In this study, we identified 19 /() genes (called ) with full-length coding sequences in hybrid H11648. Our analysis of gene expression in various types of tissues revealed the tissue-specific expression pattern of . We further examined their expression patterns at different leaf developmental stages, under abiotic/biotic stresses and nutrient deficiency. The results reveal several candidate regulators in the agave family, including // We first characterized the genes in agave based on published leaf transcriptome datasets and emphasized their potential functions. The study will benefit future studies related to nitrogen nutrient in agave.
