Cucurbit Genomics Database version 2

Version 2 of the Cucurbit Genomics database (CuGenDBv2) was released in April 2022. Database users will notice improved speed and performance.The updated database includes 33 reference genomes from 26 cucurbit species/subspecies belonging to 10 different genera; novel functions for mining and analysis of large-scale variant data; and a comprehensive cucurbit expression atlas.

CucCAP scientists examine mechanisms of watermelon resistance to viral infection

Watermelon production in the U.S. and around the world faces serious threats by viral diseases, including aphid-transmitted potyviruses: papaya ringspot virus (PRSV) and zucchini yellow mosaic virus (ZYMV). In a recent study, a CucCAP team examined expression of anti-microbial/anti-viral, ribosome-inactivating proteins (RIPs) in watermelons in response to inoculation with PRSV.  The PRSV-resistant citron watermelon (Citrullus amarus) exhibited high RIP expression, versus low expression in plants of the susceptible, cultivated “Charleston Gray” watermelon. This finding may offer additional genetic and genomic resources for improving potyvirus-resistance in watermelon cultivars.

Breaking Ground with Zhangjun Fei | BTI Discussion Series

Almost everyone is familiar with watermelon, but there is much more to the fruit than being just a sweet summer snack. Its high nutritional value and invigorating compounds have helped make watermelon the third most popular fruit in the world. Join BTI’s Dr. Zhangjun Fei in this Breaking Ground as we discuss how genomics has helped unravel the origin and breeding history of the watermelon, and how scientists continue to work to improve this fascinating fruit.
