Storage Root Development

Adventitious roots of ‘Beauregard’ and ‘Georgia Jet’ sweetpotato were observed and anatomically characterized over a period of 60 days of storage root development. The majority of ‘Beauregard’ and ‘Georgia Jet’ adventitious roots sampled at 5 to 7 days after transplanting (DAT) possessed anatomical features (five or more protoxylem elements) associated with storage root development. The majority of ‘Beauregard’ (86%) and ‘Georgia Jet’ (89%) storage roots sampled at 60 to 65 DAT were traced directly to adventitious roots extant at 5 to 7 DAT. The two varieties, however, differed in the timing in which regular and anomalous cambia were formed. Regular vascular cambium development, i.e., initiation and completion, was observed in both varieties at 19 to 21 DAT. Formation of complete regular vascular cambium was negligible for ‘Beauregard’ (4%) in comparison with ‘Georgia Jet’ (32%) at 26 to 28 DAT. However, anomalous cambia development adjacent to xylem elements was greater in ‘Beauregard’ (30%) in comparison with ‘Georgia Jet’ (13%). Nearly 40% to 50% of samples in both varieties showed extensive lignification in the stele region. At 32 to 35 DAT, 62% to 70% of the adventitious roots for both varieties had either been initiated (developed anomalous cambium) or were lignified. The remaining adventitious roots showed intermediate stages of vascular cambium development. The adventitious root count increased up to 19 to 21 DAT and then remained constant up to 32 to 35 DAT. These accumulated results suggest that the initial stages of adventitious root development are critical in determining storage root set in sweetpotato.

Abstract BackgroundSweetpotato(Ipomoea batatas (L.) Lam.) is one of the most important crops with high storage roots yield. Lignin affects the storage root formation. However, the molecular mechanisms of lignin biosynthesis in storage roots development have been lacking.ResultsTo reveal the molecular mechanism of lignin biosynthesis and identify new homologous genes in lignin biosynthesis during storage root development, the storage root (SR) at three different stages (D1, D2 and D3) in the two cultivars (Jishu25 and Jishu29) was investigated with full-length and second-generation transcriptome. A total of 52,137 transcripts and 21,148 unigenes were obtained after corrected with Hiseq2500 sequencing. Through the comparative analysis, 9577 unigenes were found to be differently expressed in the different stage in two cultivars. Among of them, 91 unigenes enriched in the phenylpropanoid biosynthesis, and 201 unigenes in hormone signal transduction pathway with KEGG analysis. Weighted gene co-expression network analysis of differentially expressed unigenes showed that lignin biosynthesis genes might be co-expressed with transcription factors such as AP2/ERF and MYB at the transcription level, and regulated by phytohormones auxin and GA3.ConclusionsTaken together, our findings will throw light on molecular regulatory mechanism of lignin biosynthesis involved in storage root development.
