Genome-wide identification of RING finger genes in flax (Linum usitatissimum) and analyses of their evolution.

ABSTRACT:

Background

Flax (Linum usitatissimum) is an important crop for its seed oil and stem fiber. Really Interesting New Gene (RING) finger genes play essential roles in growth, development, and biotic and abiotic stress responses in plants. However, little is known about these genes in flax.

Methods

Here, we performed a systematic genome-wide analysis to identify RING finger genes in flax.

Results

We identified 587 RING domains in 574 proteins and classified them into RING-H2 (292), RING-HCa (181), RING-HCb (23), RING-v (53), RING-C2 (31), RING-D (2), RING-S/T (3), and RING-G (2). These proteins were further divided into 45 groups according to domain organization. These genes were located in 15 chromosomes and clustered into three clades according to their phylogene
