Bolting refers to the early flowering stem production on agricultural and horticultural crops before harvesting. Indeed, bolting is an event induced by the coordinated effects of various environmental factors and endogenous genetic components, which cause a large reduction in the quality and productivity of vegetable crops like spinach. However, little is known about the signaling pathways and mol. functions involved in bolting mechanisms in spinach. The genetic information regarding the transition from vegetative growth to the reproductive stage in spinach would represent an advantage to regulate bolting time and improvement of resistant cultivars to minimize performance loss. To investigate the key genes and their genetic networks controlling spinach bolting, we performed RNA-seq anal. on early bolting accession Kashan and late-bolting accession Viroflay at both vegetative and reproductive stages and found a significant number of differentially expressed genes (DEGs) ranging from 195 to 1230 in different comparisons. These genes were mainly associated with the signaling pathways of vernalization, photoperiod/circadian clock, gibberellin, autonomous, and aging pathways. Gene ontol. anal. uncovered terms associated with carbohydrate metabolism, and detailed anal. of expression patterns for genes of Fructose-1, 6-bisphosphate aldolase, TREHALOSE-6-PHOSPHATE SYNTHASE 1, FLOWERING PROMOTING FACTOR 1, EARLY FLOWERING, GIGANTEA, and MADS-box proteins revealed their potential roles in the initiating or delaying of bolting. This study is the first report on identifying bolting and flowering-related genes based on transcriptome sequencing in spinach, which provides insight into bolting control and can be useful for mol. breeding programs and further study in the regulation of the genetic mechanisms related to bolting in other vegetable crops.
