Blue Green Algae (BGA) have the capacity to self generate photosynthates from CO and 2 water. It is gratifying to note that Aulosira is the most important alga of the rice fields of India. Algalization has been found to benefit all the growth parameters. The propagation of BGA enriches the N status of soil and also provides organic matter and biological quotient 2 substances for plant growth. T...

Selective pressures acting on plant life histories can drive extreme specialization. One example of such specialization is the evolution of dioecious breeding systems. Evolutionary and ecological theory posits that dioecy may subject male and female individuals to different selective pressures and result in unique sex-mediated adaptive traits related to resource allocation and ecophysiology. Cy...

Pseudomonas stutzeri A1501, associative and endophytic nitrogen-fixing bacterium showed the capacity of colonization in the rice roots and considered as the good colonizer in the rice plant. The experiment was conducted to study the expression of genes potentiality relevant to the association of nitrogen fixing Pseudomonas stutzeri with host rice and reveal the molecular mechanism by which unde...

Nitrogen (N) is one of the elements most needed by plants and widely distributed in nature. fixation can occur symbiotic or non-symbiotic soil microbes. This research aimed to examine potential N-fixing microbes increasing availability N soil. was conducted at Soil Biology Laboratory Faculty Agriculture, Universitas Sumatera Utara. The results showed that ability increase varied. population bac...

In this study, the nitrogen fixing bacteria VIT SS 1-6 were screened from the root nodules of Groundnut (Family: Fabaceae, Species: Arachis hypogaea) collected from Vellore district were examined for their plant growth promoting properties. Of the six isolates obtained, five were fast growing and one was slow growing. The slow growing species VIT SS5 was further examined for its nitrogen fixing...

The availability of nitrogen is one of the major limiting factors to crop growth. In the developed world, farmers use unsustainable levels of inorganic fertilisers to promote crop production. In contrast, in the developing world inorganic fertilisers are often not available and small-holder farmers suffer the resultant poor yields. Finding alternatives to inorganic fertilisers is critical for s...

Legumes have evolved symbiotic interactions with rhizobial bacteria to efficiently utilize nitrogen. Recent progress in symbiosis has revealed several key components of host plants required for nitrogen-fixing nodule organogenesis, in which complicated metabolic and signaling pathways in the host plant are reprogrammed to generate nodules in the cortex upon perception of the rhizobial Nod facto...
