We describe two prolonged bacteriophage blooms within sugar beet rhizospheres ensuing from an artificial increase in numbers of an indigenous soil bacterium. Further, we provide evidence of in situ competition between these phages. This is the first in situ demonstration of such microbial interactions in soil. To achieve this, sugar beet seeds were inoculated with Serratia liquefaciens CP6RS or...

abstract large-scale mortality of in vitro raisedplantlets occurred during acclimatization, i.e. glasshouse hardening, and later at field transfer still has remained as a significant bottleneck in micropropagation. the usefulness potential of some arbuscular mycorrhizal fungi (amf) to minimize mortality rate of three commercial grape rootstock genotypes during glasshouse acclimatization was stu...

Histone deacetylases (HDACs) play an important role in plant growth, development, and defense processes and are one of the primary causes of epigenetic modifications in a genome. There was only one study reported on epigenetic modifications of the important legume crop, common bean, and its interaction with the fungal rust pathogen Uromyces appendiculatus prior to this project. We measured the ...

using plant probiotic bacteria, which can induce systemic tolerance in plants, is one of the most important strategy to reduce the damage of drought stress in plants. in this study the effect of four fluorescent strains (t17-4, vupf5, 428, cha0) was investigated on resistance of two pistachio cultivars (badami-rize-zarand and sarakhs) against the drought stress. a completely randomized design w...

BACKGROUND On the one hand, the critical nitrogen (N) content curve allows the minimal N content necessary for maximum growth rate at any stage of crop development to be predicted. On the other hand, arbuscular mycorrhizal fungi (AMF) transfer N from the soil to the plants and its growth and activity depends on the availability of soil N. Our objective was to investigate how the availability of...

Xylella fastidiosa (Xf) is a fastidious gram-negative, xylem-limited bacterium that causes diseases in many crops of economic importance, such as grape (Pierce’s disease), almond, peach, coffee, plum and citrus. Xf can infect all known Citrus sinensis cultivars and causes Citrus variegated chlorosis (CVC). One major endophyte isolated from CVC-asymptomatic plants is the bacterium Curtobacterium...

Rice seedlings were inoculated with Azospirillum sp. B510 and transplanted into a paddy field. Growth in terms of tiller numbers and shoot length was significantly increased by inoculation. Principal-coordinates analysis of rice bacterial communities using the 16S rRNA gene showed no overall change from B510 inoculation. However, the abundance of Veillonellaceae and Aurantimonas significantly i...

Virus-induced gene silencing is currently a powerful tool for the study of gene function in plants. Here, we optimized the protocol for virus-induced gene silencing, and investigated factors that affect the efficiency of tobacco rattle virus-induced gene silencing in pepper plants. Consequently, an optimal protocol was obtained by the syringe-infiltration method in the leaves of pepper plants. ...
