Whether you prefer a Cabernet Sauvignon or a Pinot Noir grape variety, two new research articles reported in the online open access journal, BMC Genomics, offer a host of new genetic information on fruit ripening for this economically important fruit crop. The grapevine's gene expression analysis reveals two distinct molecular and functional phases that correspond with the green and red grape stages. And scientists have reported the first biochemical evidence that reactive oxygen species accumulate during the colour transition. Stefania Pilati and fellow scientists from the IASMA Research Center, San Michele all'Adige, Italy, investigated ripening Pinot Noir grapes (Vitis vinifera L.) to identify fruit ripening genes and investigate seasonal influences. They found a core set of more than 1,400 ripening-specific genes that fluctuated similarly across three growing seasons and a smaller gene group strongly influenced by climatic conditions........
