Searching and detecting in some harsh environments such as collapsed buildings, pipes, small cracks are crucial for human rescue and industrial detection, military surveillance etc. However, the drawbacks of traditional moving modes of current vehicles make them difficult to perform such tasks. So developing some new vehicles is urgent. Here, we report a Setaria viridis spike's interesting beha...

The architecture of a plant affects its ability to compete for light and to respond to environmental stresses, thus affecting overall fitness and productivity. Two components of architecture, branching and height, were studied in 182 F7 recombinant inbred lines (RILs) at the vegetative, flowering and mature developmental stages in the panicoid C4 model grass system, Setaria. The RIL population ...

Nine eriophyoid mites, including two new species and five new records, from Iran are described and illustrated. They are Aceria acroptiloni Shevchenko & Kacalev, 1974, rec. n. on Rhaponticum repens (L.) Hidalgo (Asteraceae); Aceria anthocoptes (Nalepa, 1892), rec. n. on Cirsium arvense (L.) Scop. (Asteraceae); Aceria lactucae (Canestrini, 1893), rec. n. on Lactuca virosa L. (Asteraceae); Aceria...

Employing reference genes to normalize the data generated with quantitative PCR (qPCR) can increase the accuracy and reliability of this method. Previous results have shown that no single housekeeping gene can be universally applied to all experiments. Thus, the identification of a suitable reference gene represents a critical step of any qPCR analysis. Setaria viridis has recently been propose...

Leaves of almost all C4 lineages separate the reactions of photosynthesis into the mesophyll (M) and bundle sheath (BS). The extent to which messenger RNA profiles of M and BS cells from independent C4 lineages resemble each other is not known. To address this, we conducted deep sequencing of RNA isolated from the M and BS of Setaria viridis and compared these data with publicly available infor...

The photosynthetic assimilation of CO2 in C4 plants is potentially limited by the enzymatic rates of Rubisco, phosphoenolpyruvate carboxylase (PEPc), and carbonic anhydrase (CA). Therefore, the activity and kinetic properties of these enzymes are needed to accurately parameterize C4 biochemical models of leaf CO2 exchange in response to changes in CO2 availability and temperature. There are cur...

BACKGROUND Recently, there has been interest in establishing a monocot C4 model species with a small genome, short lifecycle, and capacity for genetic transformation. Setaria viridis has been adopted to fill this role, since reports of Agrobacterium-mediated transformation in 2010, and sequencing of its genome in 2012. To date, S. viridis has primarily been used to further our understanding of ...

Saline stress affects plants’ performance, causing change at the morphological and physiological levels. Several genotypes have developed mechanisms to face salinity, avoiding or tolerating it. Potassium supply is considered an advantageous strategy reduce salt injury improve plant tolerance. In this study, we used three accessions (A10.1, ME034V Ast-1) of Setaria viridis (L.) P.Beauv., a C4 mo...
