We combined transcriptomic and biochemical approaches to study rhizobial and plant sulfur (S) metabolism in nitrogen (N) fixing nodules (Fix(+)) of Lotus japonicus, as well as the link of S-metabolism to symbiotic nitrogen fixation and the effect of nodules on whole-plant S-partitioning and metabolism. Our data reveal that N-fixing nodules are thiol-rich organs. Their high adenosine 5'-phosphos...

Soil salinization is a major threat to agriculture in arid and semi-arid regions, where water scarcity and inadequate drainage of irrigated lands severely reduce crop yield. Salt accumulation inhibits plant growth and reduces the ability to uptake water and nutrients, leading to osmotic or water-deficit stress. Salt is also causing injury of the young photosynthetic leaves and acceleration of t...

BiofertiJizers are microbial preparations containing living cells of different microorganisms which have the ability to mobilize plant nutrients in soil from unusable to usable form through biological process. They are environmental friendly and play significant role in crop production. Previollsly it is mainly used for field crops but now-a-days it is used for fruit crops also. Biofertilizers ...

A single gram of soil is said to contain more than 8 billion bacterial cells, representing up to 50,000 different species1. These microorganisms play important roles, from tweaking how plants interact with their surroundings to influencing the chemical composition of the environment2. Now, the increased affordability of DNA sequencing technologies has enabled scientists to gain a deeper underst...

In diesem Beitrag wird ein Programm zur effektiven Sicherheitssensibilisierung im Unternehmen entwickelt. Schwerpunkte des Programms liegen auf Bedrohungsszenarien, der Form eines ‚Alternate Reality Game‘ zur Wissensvermittlung und messbaren Erfolgsgrößen. Mithilfe des Programms soll eine dauerhafte Verhaltensänderung erreicht werden.

Formaldehyde (HCHO) is an air pollutant suspected of being carcinogenic and a cause of sick-house syndrome. Microorganisms called methylotrophs, which can utilize reduced C(1) compounds such as methane and methanol, fix and assimilate HCHO, whereas most plants are unable to assimilate HCHO directly. We found that a bacterial formaldehyde-fixing pathway (ribulose monophosphate pathway) can be in...

Numerous genomic-based studies have provided insight to the physiological and evolutionary processes involved in developmental and environmental processes of model plants such as arabidopsis and rice. However, far fewer efforts have been attempted to use genomic resources to study physiological and evolutionary processes of weedy plants. Genomics-based tools such as extensive EST databases and ...

Broomrapes are obligate root parasitic weeds and major constraint to many dicotyledoncrops especially in Mediterranean agricultural lands. Due to the fact that no single controlmeasure is able to control broomrapes in the field satisfactorily, integrated management isrecommended in general. The use of of trap crops or catch crops is an important strategy forcontrolling the weeds; and allelopath...

One of the most commonly seeded crops in Canada is canola, a cultivar of oilseed rape (Brassica napus). As a mass-flowering crop grown intensively throughout the Canadian Prairies, canola has the potential to influence pollinator success across tens of thousands of square kilometers of cropland. Bumble bees (Bombus sp.) are efficient pollinators of many types of native and crop plants. We measu...
