QTL mapping of dormancy in Barley using the Harrington/Morex and Chevron/Stander mapping populations
Grain dormancy in barley (Hordeum vulgare L.) is quantitatively inherited. Low levels of dormancy before harvest can lead to pre-harvest sprouting (PHS) in the field, which affects grain and malt quality. The objective of the present study was to determine the locations and effects of quantitative trait loci (QTLs) controlling dormancy in two F1–derived doubled-haploid (DH) populations from the ...

Aspergillus nidulans arfb plays a role in endocytosis and polarized growth
Filamentous fungi undergo polarized growth throughout most of their life cycles. The Spitzenkörper is an apical organelle composed primarily of vesicles that is unique to filamentous fungi and is likely to act as a vesicle supply center for tip growth. Vesicle assembly and trafficking are therefore important for hyphal growth. ADP ribosylation factors (Arfs), a group of small GTPase proteins, ...

Nadph oxidases nox-1 and nox-2 require the regulatory subunit nor-1 to control cell differentiation and growth in neurospora crassa
We have proposed that reactive oxygen species (ROS) play essential roles in cell differentiation. Enzymes belonging to the NADPH oxidase (NOX) family produce superoxide in a regulated manner. We have identified three distinct NOX subfamilies in the fungal kingdom and have shown that NoxA is required for sexual cell differentiation in Aspergillus nidulans. Here we show that Neurospora crassa NOX-1 ...

The crucial role of the pls1 tetraspanin during ascospore germination in podospora anserina provides an example of the convergent evolution of morphogenetic processes in fungal plant pathogens and saprobes{triangledown}
Pls1 tetraspanins were shown for some pathogenic fungi to be essential for appressorium-mediated penetration into their host plants. We show here that Podospora anserina, a saprobic fungus lacking appressorium, contains PaPls1, a gene orthologous to known PLS1 genes. Inactivation of PaPls1 demonstrates that this gene is specifically required for the germination of ascospores in P. ...

Recurrent restricted phenotypic selection for improving stand establishment of Bahiagrass
Bahiagrass (Paspalum notatum Flügge) is an important perennial forage grass for the southeastern United States, being well adapted to conditions such as sandy or poorly drained soils, drought, and heavy continuous grazing. Current bahiagrass cultivars germinate over an extended period of time and the slow emergence produces incomplete stands, allowing weeds to compete and delaying grazing or ...

Phenotypic and genomic responses to titanium dioxide and cerium oxide nanoparticles in Arabidopsis germinants
The effects of exposure to nanoparticles of titanium dioxide (nano‐titanium) and cerium oxide (nano‐cerium) on gene expression and growth in Arabidopsis thaliana germinants were studied using microarrays and quantitative real‐time polymerase chain reaction (qPCR), and by evaluating germinant phenotypic plasticity. Exposure to 12 days of either nano‐titania or nano‐ceria altered the regulation ...

A Saline Duper Wheat that Tolerates Higher Salt Concentrations!
In the past few decades, agricultural land has been largely lost, and increased salinity in soils around the world has received much attention. Nowadays, nearly 8% of the world's arable land can no longer be used for crop cultivation due to salt pollution, and more than half of the world's countries are affected. Wheat is the second largest grain grown after corn and grows more on Earth than any ...
