Cotton fiber length, a key determinant of its industrial utility, is one of the most important agricultural traits subjected to domestication. However, the genetic determinants and molecular mechanisms underlying natural variation in fiber length remain inadequately characterized. We identified GhTTL as a critical positive regulator of fiber elongation through genome-wide association analysis (GWAS).

Purpose: Pichia pastoris is well known for its ability to produce short and low-immunogenic humanized glycosyl chains onto recombinant glycoproteins, it was thus speculated to be applicable to synthesize oligosaccharides. In this study, generally recognized as safe (GRAS) microorganism Pichia pastoris GS115 was tested for its potential to be used as a new synthetic chassis to produce the most abundant human milk oligosaccharide 2'-fucosyllactose (2'-FL).

Methods: To enable the de novo synthesis of 2'-FL, lactose transporter lac12, two enzymes of gmd, gmer, and fucosyltransferases futC were integrated into the genome of P.

With the increasing amount of cotton omics data, breeding scientists are confronted with the question of how to use massive cotton data to mine effective breeding information. Here, we construct a Resource And Network Database (GRAND), which integrates 18 cotton genome sequences, genome annotations, two cotton genome variations information, and also four transcriptomes for species. GRAND allows to explore and mine this data with the help of a toolbox that comprises a flexible search system, BLAST and BLAT suite, orthologous gene ID, networks of co-expressed genes, primer design, Gbrowse and Jbrowse, and drawing instruments.

Golgi Membrane Protein 1 (GOLM1) has been identified as a prime target for cancer therapy because it overexpresses in many solid tumors, increases tumor growth and metastasis and leads to unfavorable survival. Though various approaches including siRNA interference and antibody targeting have been attempted, GOLM1 has remained an un-targetable molecule because of its mainly intracellular location and the lack of domains that could possibly be interfered with by small molecules. Numerous natural anti-tumoral plant substances have been identified, while their possible function on GOLM1 has never been revealed.

Upland cotton is the most widely planted for natural fiber around the world, and either lint percentage (LP) or fiber length (FL) is the crucial component tremendously affecting cotton yield and fiber quality, respectively. In this study, two lines MBZ70-053 and MBZ70-236 derived from CCRI70 recombinant inbred line (RIL) population presenting different phenotypes in LP and FL traits were chosen to conduct RNA sequencing on ovule and fiber samples, aiming at exploring the differences of molecular and genetic mechanisms during cotton fiber initiation and elongation stages.
