Sesame (Sesamum indicum L., 2n = 26) is an important oilseed crop with an estimated genome size of 369 Mb. The genetic basis, including the number and locations of quantitative trait loci (QTLs) of sesame grain yield and quality remain poorly understood, due in part to the lack of reliable markers and genetic maps. Here we report on the construction of a(More)
Drought stress encumbers the seed germination and delays seedling establishment in dry direct-seeded rice. Pot and field studies were carried out to ascertain the role of seed-priming on emergence, seedling growth and associated metabolic events in dry-direct seeded rice system. Seeds of two indica rice cultivars were subjected to different priming agents(More)
Sesame is an important and ancient oil crop in tropical and subtropical areas. China is one of the most important sesame producing countries with many germplasm accessions and excellent cultivars. Domestication and modern plant breeding have presumably narrowed the genetic basis of cultivated sesame. Several modern sesame cultivars were bred with a limited(More)
Barley yellow dwarf viruses (BYDVs, mainly consisting of three strains, GAV, GPV and PAV, in China), barley stripe mosaic virus (BSMV), wheat yellow mosaic virus (WYMV), wheat dwarf virus (WDV) and wheat blue dwarf phytoplasma (WBD) constitute a group of major wheat pathogens that have caused huge yield losses but are scarcely distinguished by their(More)
This paper presents a novel alignment approach for imperfect speech and the corresponding transcription. The algorithm gets started with multi-stage sentence boundary detection in audio, followed by a dynamic programming based search, to find the optimal alignment and detect the mismatches at sentence level. Experiments show promising performance, compared(More)
Kelp (Saccharina japonica) has been intensively cultured in China for almost a century. Its genetic improvement is comparable with that of rice. However, the development of its molecular tools is extremely limited, thus its genes, genetics and genomics. Kelp performs an alternative life cycle during which sporophyte generation alternates with gametophyte(More)
The ZmRXO1 gene is a nucleotide-binding site leucine-rich repeat (NBS–LRR) type of R gene in maize (Zea mays). To understand the regulatory mechanism of ZmRXO1 gene expression, we isolated and characterized the ZmRXO1 promoter (PZmRXO1)—the 5′ flanking region of ZmRXO1. A series of PZmRXO1 deletion derivatives, R1–R4, from the translation start code(More)
All positive-stranded RNA viruses with genomes>∼7 kb encode helicases, which generally are poorly characterized. The core of the nidovirus superfamily 1 helicase (HEL1) is associated with a unique N-terminal zinc-binding domain (ZBD) that was previously implicated in helicase regulation, genome replication and subgenomic mRNA synthesis. The high-resolution(More)
