Phytoene synthase 1 (Psy1) and lipoxygenase 1 (Lpx-1) are key genes involved in the synthesis and catalysis of carotenoid pigments in durum wheat, regulating the increase and decrease in these compounds, respectively, resulting in the distinct yellow color of semolina and pasta. Here, we reported new haplotype variants and/or allele combinations of these two genes significantly affecting yellow pigment content in grain and semolina through their effect on carotenoid pigments. To reach the purpose of this work, three complementary approaches were undertaken: the identification of QTLs associated to carotenoid content on a recombinant inbred line (RIL) population, the characterization of a Mediterranean panel of accessions for Psy1 and Lpx-1 genes, and monitoring the expression of Psy1 and Lpx-1 genes during grain filling on two genotypes with contrasting yellow pigments. Our data suggest that Psy1 plays a major role during grain development, contributing to semolina yellowness, and Lpx-1 appears to be more predominant at post-harvest stages and during pasta making.

Yellow pigments are apparent in some foods prepared from wheaten flour or semolina, and may affect the visual appeal of the product. A survey of the yellow pigment content of flours milled from eighteen common varieties of Australian wheat has been completed. Those of the variety Mendos gave the lowest mean figure of 1.45 parts per million whereas the figure for Festival, 4.33, was the highest. Yellow pigment content was not related to protein level or milling yield within the range of material examined.

Palm liquid sewage is organic waste that contains complex compounds such as water, oil, and organic solids. The organic content of palm liquid sewages is an indication of the abundance of microorganisms. This study aims to obtain anoxygenic photosynthetic bacteria (BFA) that produce carotenoid pigments from palm liquid sewages. Therefore, We isolated and screened of BFA from three palm liquid sewage disposal sites in Jambi Province. This research was conducted by an experimental method using a modified mineral medium. BFA isolates that growth and produced carotenoid pigments are visible because of the distribution of reddish-yellow pigments on the culture media. Screening results obtained 11 isolates of BFA sequentially Bg1K201, Bg1K202, Bg2k201, Bg3k201, Mr1k201, Mr1k202, Sl1k201, Sl1k202, Sl2k201, Sl2k202 and Sl3k202. The results of morphological and physiological characterization based on the Bergeys Manual of Determinative Bacteriology show that there are two types of BFA genera that have carotenoid pigments, respectively, the genus Rhodobacter (Bg1k201, Bg1k202, Bg3k201, Sl1k201, Sl1k202, and Sl1k202, and Sl2k202, and Sl1k202, and Sl2k202, and Sl1k202 and Sl2k202, and Sl2k202, and Sl2k202.

Hexaploid tritordeums are the amphiploids derived from the cross between the wild barley Hordeum chilense and durum wheat. Tritordeums are characterised by higher yellow pigment content in their seeds than their durum wheat progenitors due to certain H. chilense genes located on the α arm of chromosome 7Hch. In this work a candidate gene approach based on the phytoene synthase gene (PSY) was followed to investigate whether PSY1 may be responsible for the high carotenoid content in tritordeum and to develop a diagnostic marker for H. chilense PSY. This gene codes for the first step in the carotenoid biosynthetic pathway. It was first demonstrated that PSY is duplicated in H. chilense, Triticum urartu, and durum wheat (PSY1 and PSY2), and subsequently a diagnostic cleaved amplified polymorphism (CAP) marker able to differentiate between H. chilense and durum wheat PSY1 was developed. Using this CAP marker and a set of H. chilense-common wheat addition lines it was found that PSY1 is located on the α arm of chromosome 7Hch, where the gene(s) for yellow pigment content are located. PSY1 is located on chromosomes 7A and 7B of durum wheat as demonstrated using Langdon substitution lines. Furthermore, synteny between rice and wheat indicates that PSY1 should be located on the long arms of chromosomes 7A and 7B, in agreement with QTL data for yellow pigment content. Together, these results suggest that PSY1 may be a good candidate gene for further work with yellow pigment content in both durum wheat and tritordeum. In addition, the diagnostic CAP marker developed will be used in our breeding program to transfer H. chilense genes to durum wheat, to evaluate their potential for durum wheat improvement.

Abstract Background Rice is an important food source for humans worldwide. Because of its nutritional and agricultural significance, a number of studies addressed various aspects of rice grain development and grain filling. Nevertheless, the molecular processes underlying grain filling and development, and in particular the contributions of different grain tissues to these processes, are not understood. Main Text Using RNA-sequencing, we profiled gene expression activity in grain tissues comprised of cross cells (CC), the nucellar epidermis (NE), ovular vascular trace (OVT), endosperm (EN) and the aleurone layer (AL). These tissues were dissected using laser capture microdissection (LCM) at three distinct grain development stages. The mRNA expression datasets offer comprehensive and new insights into the gene expression patterns in different rice grain tissues and their contributions to grain development. Comparative analysis of the different tissues revealed their similar and/or unique functions, as well as the spatio-temporal regulation of common and tissue-specific genes. The expression patterns of genes encoding hormones and transporters indicate an important role of the OVT tissue in metabolite transport during grain development. Gene co-expression network prediction on OVT-specific genes identified several distinct and common development-specific transcription factors. Further analysis of enriched DNA sequence motifs proximal to OVT-specific genes revealed known and novel DNA sequence motifs relevant to rice grain development. Conclusion Together, the dataset of gene expression in rice grain tissues is a novel and useful resource for further work to dissect the molecular and metabolic processes during rice grain development.
