background: physical characteristics of crops play an important role in designing the required machinery and apparatus for planting, harvesting, transport, processing and also storing. the aim of this study was to determine physical characteristics of some native rice varieties cultivated in northern iran, namely gerde, shafagh, tarom-e-hashemi, shiroodi and keshvari. methods: some geometrical,...

Leaf senescence is related to the grain-filling rate and grain weight in cereals. Many components involved in senescence regulation at either the genetic or physiological level are known. However, less is known about molecular regulation mechanisms. Here, we report that OsFBK12 (an F-box protein containing a Kelch repeat motif) interacts with S-ADENOSYL-L-METHIONINE SYNTHETASE1 (SAMS1) to regul...

Tilletia horrida is the most destructive fungal pathogen of rice (Oryza sativa L.). The 20,105,270-bp draft genome sequence of T. horrida strain QB-1 is reported here. Genes encoding proteins associated with key virulence factors were predicted, and this can provide information for understanding the pathogenic mechanisms in T. horrida.

A cDNA encoding a predicted 15-kDa protein was earlier isolated from sugar-induced genes in rice embryos (Oryza sativa L.) by cDNA microarray analysis. Here we report that this cDNA encodes a novel Ca2+-binding protein, named OsSUR1 (for Oryza sativa sugar-up-regulated-1). The recombinant OsSUR1 protein expressed in Escherichia coli had 45Ca2+-binding activity. Northern analysis showed that the...

Bacillus velezensis CBMB205 (= KACC 13105(T) = NCCB 100236(T)) was isolated from the rhizoplane of rice (Oryza sativa L. cv. O-dae). According to previous studies, this bacterium has several genes that can promote plant growth, such as the phosphorus-solubilizing protein-coding gene. Here, we present the first complete genome of B. velezensis CBMB205.
