The Plant Genome Research Highlights

How Maize Resists Hungry Worms Revealed


Corn, or maize, is a staple crop of global economic, industrial, and food security importance. Damage to the growing ears by corn earworm (CEW) can reduce yield, and is thus a major economic burden to farmers. CEW damage to ears can also increase secondary fungal infections and levels of deadly mycotoxins.

Genome to phenome mapping in apple using historical data


Apple is one of the world’s most valuable fruit crops, but its large size and long juvenile phase prior to producing fruit make breeding new cultivars time consuming and expensive. Marker-assisted selection (MAS) can significantly decrease the time required for breeding new apple cultivars by allowing plants with a desired trait to be selected at the seed or seedling stage. However, MAS requires the discovery of genetic markers that predict traits of interest to breeders.

Pectinesterases contribute to increased ascorbic acid content in tomato


Ascorbic acid is an essential vitamin in the human diet, being positively correlated with a reduction in risk of different diseases. In a recent study published in The Plant Genome, Ruggieri et al. report the identification of a group of genes that increases the levels of ascorbic acid in tomato fruit by combining genomics, transcriptomics, and bioinformatics data.
