Optimization of alkali pretreatment and enzymatic saccharification of jute (Corchorus olitorius L.) biomass using response surface methodology.

Reduction of inherent structural recalcitrance and improved saccharification efficiency are two important facets to enhance fermentable sugar yield for bioethanol production from lignocellulosic biomass. This study optimized alkaline pretreatment and saccharification conditions employing response surface methodology to improve saccharification yield of jute (Corchorus olitorius cv. JROB-2) biomass.

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.

Confamiliar transferability of simple sequence repeat (SSR) markers from cotton (Gossypium hirsutum L.) and jute (Corchorus olitorius L.) to twenty two Malvaceous species.

Cross-species transferability is a quick and economic method to enrich SSR database, particularly for minor crops where little genomic information is available. However, transferability of SSR markers varies greatly between species, genera and families of plant species. We assessed confamiliar transferability of SSR markers from cotton (Gossypium hirsutum) and jute (Corchorus olitorius) to 22 species distributed in different taxonomic groups of Malvaceae.

Start codon targeted (SCoT) polymorphism reveals genetic diversity in wild and domesticated populations of ramie (Boehmeria nivea L. Gaudich.), a premium textile fiber producing species.

Twenty-four start codon targeted (SCoT) markers were used to assess genetic diversity and population structure of indigenous, introduced and domesticated ramie (Boehmeria nivea L. Gaudich.).

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 %).

Research advances in major cereal crops for adaptation to abiotic stresses.

With devastating increase in population there is a great necessity to increase crop productivity of staple crops but the productivity is greatly affected by various abiotic stress factors such as drought, salinity. An attempt has been made a brief account on abiotic stress resistance of major cereal crops viz. In spite of good successes obtained on physiological and use molecular biology, the benefits of this high cost technology are beyond the reach of developing countries.
