High throughput sequencing identifies chilling responsive genes in sweetpotato (Ipomoea batatas Lam.) during storage

Project description:Sweetpotato (Ipomoea batatas L.) is a globally important economic food crop. It belongs to Convolvulaceae family and origins in the tropics; however, sweetpotato is sensitive to cold stress during storage. In this study, we performed transcriptome sequencing to investigate the sweetpotato response to chilling stress during storage. A total of 110,110 unigenes were generated via high-throughput sequencing. Differentially expressed genes (DEGs) analysis showed that 18,681 genes were up-regulated and 21,983 genes were down-regulated in low temperature condition. Many DEGs were related to the cell membrane system, antioxidant enzymes, carbohydrate metabolism, and hormone metabolism, which are potentially associated with sweetpotato resistance to low temperature. The existence of DEGs suggests a molecular basis for the biochemical and physiological consequences of sweetpotato in low temperature storage conditions. Our analysis will provide a new target for enhancement of sweetpotato cold stress tolerance in postharvest storage through genetic manipulation.

Assessing the remarkable morphological diversity and transcriptomic basis of leaf shape in Ipomoea batatas (sweetpotato)

Project description:Leaf shape is a spectacularly diverse trait that influences various aspects of plant physiology, and is even correlated with crop yield and quality in multiple species. However, only a few genetic dissections of leaf shape have been accomplished at a species-wide level. Here, we perform an initial characterization of leaf shape variation in Ipomoea batatas, the sweetpotato, at multiple scales of analysis. We use a transcriptomic survey to identify gene expression changes associated with two commonly studied leaf shape traits--circularity and aspect ratio using 19 individuals (accession) of sweetpotato. We comprehensively describe the remarkable morphological diversity in leaf shape in sweetpotato, and identify 147 differentially regulated genes associated with circularity and aspect ratio, providing an initial set of hypotheses regarding the genetic basis of leaf shape in this species.
