Genomic Comparison and Population Diversity Analysis Provide Insights into the Domestication and Improvement of Flax.

Flax has been cultivated for its oil and fiber for thousands of years. However, it remains unclear how the modifications of agronomic traits occurred on the genetic level during flax cultivation. In this study, we conducted genome-wide variation analyses on multiple accessions of oil-use, fiber-use, landraces, and pale flax to identify the genomic variations during flax cultivation.

Consensus genetic linkage map construction and QTL mapping for plant height-related traits in linseed flax (Linum usitatissimum L.).

Background: Flax is an important field crop that can be used for either oilseed or fiber production. Plant height and technical length are important characters for flax. For linseed flax, plants usually have a short technical length and plant height than those for fiber flax.

Identification and functional analysis of two alternatively spliced transcripts of ABSCISIC ACID INSENSITIVE3 (ABI3) in linseed flax (Linum usitatissimum L.).

Alternative splicing is a popular phenomenon in different types of plants. It can produce alternative spliced transcripts that encode proteins with altered functions. Previous studies have shown that one transcription factor, ABSCISIC ACID INSENSITIVE3 (ABI3), which encodes an important component in abscisic acid (ABA) signaling, is subjected to alternative splicing in both mono- and dicotyledons.

De novo assembly of the desert tree Haloxylon ammodendron (C. A. Mey.) based on RNA-Seq data provides insight into drought response, gene discovery and marker identification.
