Comparative genomics profiling revealed multi-stress responsive roles of the CC-NBS-LRR genes in three mango cultivars.

Researchers constructed the pan-genome of three mango cultivars and identified a total of 47, 27, and 36 CC-NBS-LRR genes in each cultivar respectively. These genes play a role in defense mechanisms and are involved in multiple stress conditions, providing insights into the functional characteristics of the mango CNL gene family.

Genome-wide identification of PEBP gene family in pineapple reveal its potential functions in flowering.

This study investigates the role of PEBP in regulating flowering time and morphogenesis in pineapple. It identifies 11 PEBP family members and explores their expression patterns. Overexpression of a specific gene resulted in early flowering, and potential flower regulators were identified. Valuable insights into pineapple flower development and guidance for future studies are provided.

Chromosomal-scale genomes of two Rosa species provide insights into genome evolution and ascorbate accumulation.

Scientists sequenced the genomes of Rosa roxburghii and Rosa sterilis to understand their hybrid origin and absence of recent whole-genome duplications. They found that duplicated genes may contribute to flavonoid accumulation and identified key regulatory genes for ascorbate synthesis. Terpene synthase genes may be involved in terpenoid biosynthesis. This study sheds light on genome evolution and the molecular basis of high ascorbate concentration in these Rosa species.
