Resolving population structure and genetic differentiation associated with RAD-SNP loci under selection in tossa jute (Corchorus olitorius L.).

The genetic basis of selection for geographic adaptation and how it has contributed to population structure are unknown in tossa jute (Corchorus olitorius), an important bast fibre crop. We performed restriction site-associated DNA (RAD) sequencing-based (1115 RAD-SNPs) population genomic analyses to investigate genetic differentiation and population structure within a collection of 221 fibre-type lines from across nine geographic regions of the world. Indian populations, with relatively higher overall diversity, were significantly differentiated (based on F and PCA) from the African and the other Asian populations.

Transcriptome profiling uncovers β-galactosidases of diverse domain classes influencing hypocotyl development in jute (Corchorus capsularis L.).

Enzyme β-galactosidase (EC 3.2.1.

The draft genome of cv. JRO-524 (Navin).

Here, we present the draft genome (377.3 Mbp) of cv. JRO-524 (Navin), which is a leading dark jute variety developed from a cross between African (cv.

SSR and morphological trait based population structure analysis of 130 diverse flax (Linum usitatissimum L.) accessions.

A total of 130 flax accessions of diverse morphotypes and worldwide origin were assessed for genetic diversity and population structure using 11 morphological traits and microsatellite markers (15 gSSRs and 7 EST-SSRs). Analysis performed after classifying these accessions on the basis of plant height, branching pattern, seed size, Indian/foreign origin into six categories called sub-populations viz. fibre type exotic, fibre type indigenous, intermediate type exotic, intermediate type indigenous, linseed type exotic and linseed type indigenous.

Pathways associated with lignin biosynthesis in lignomaniac jute fibres.

We generated the bast transcriptomes of a deficient lignified phloem fibre mutant and its wild-type jute (Corchorus capsularis) using Illumina paired-end sequencing. A total of 34,163 wild-type and 29,463 mutant unigenes, with average lengths of 1442 and 1136 bp, respectively, were assembled de novo, ~77-79 % of which were functionally annotated. These annotated unigenes were assigned to COG (~37-40 %) and GO (~22-28 %) classifications and mapped to 189 KEGG pathways (~19-21 %).
