Botanically, the fibers harvested from many of these plants are bast fibers; the fibers come from the phloem tissue of the plant. Bast fibre (also called phloem fibre or skin fibre) is plant fibre collected from the phloem (the inner bark, sometimes called skin) or bast surrounding the stem of certain dicotyledonous plants. As all bast fibres contain non-cellulose matter such as pectin, lignin, and hemicellulose, degumming or retting is needed to remove the non-cellulose matter. Bast fibers are used for textiles, rope, and paper. Phloem fibres The fibres of sclerenchyma associated with phloem are called from COMP 2012 at South Australia It is responsible for transporting food from the leaves to the other parts of the plant. 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.

Key words: Jute, Corchorus capsularis , vascular development, mutant, secondary phloem fibre, lignin. The best fibres occur in the outer portion of the stem, interspersed with thin-walled tissues of phloem. 3. is a complex process that involves the differentiation of secondary phloic fibres (SPF) from the cambium followed by lignification of the fibre wall.
