Plant growth promoting rhizobacteria (PGPR) are the residents of rhizosphere that are known to influence plant growth and survival through the production of various regulatory chemicals under a variety of circumstances. This growth promotion is accomplished by both direct and indirect means. Direct effects of PGPR encompass two major activities, that is, Bio-fertilization (Enhancement of nutrient...
The concerns of people over the wide use of chemicals are determining an increasing attention to more eco-friendly management practices in agriculture. Plant growth promoting rhizobacteria (PGPR) are emerging as important beneficial microbial inoculants because of their capability to promote plant growth and improve plant protection. We performed RNASeq to analyze gene expression profiling at 24,...
Seed-vectored endophytes internally colonize plant seeds and remain without eliciting disease symptoms. Microbes are carried by seeds generation after generation to benefit the host during and following seed germination. Seed-vectored endophytes have been poorly investigated and research targeted at understanding their biology will have immense applications in agriculture and horticulture. Some reports...
Organic farmers recognize the importance of using Rhizobium to meet crop N fertility needs and to reduce use of chemical fertilizers. Field experiments were conducted during the 2015 and 2016 seasons at different organic fields to assess the effect of indigenous Rhizobium leguminosarum bv. phaseoli (OrgK9) and commercial R. tropici (CIAT899) strains on symbiotic performance and grain yield of bean...
Phosphorus plays an indispensable part in keeping up soil richness and securing global sustenance production, however, its chief proportions remain interlocked in various insoluble forms of Ca, Fe and Al ion precipitates that cannot be taken by the plants proficiently. This prompts to an indiscriminate application of phosphatic chemical fertilizers to the crop field which has led to substantial pollution...
Azolla is a small genus of diminutive aquatic ferns with a surprisingly vast potential to benefit the environment and agriculture, as well as to provide insight into the evolution of plant-cyanobacterial symbioses. This capability is derived from the unique relationship Azolla spp. have with their obligate, nitrogen-fixing cyanobacterial symbiont, Nostoc azollae, that resides in their leaves. Although...
The associations between Cephalotrichella echinicola Chernyshev et al., 2019, and the heart urchin Metallia spp. described here represent the first report on the symbiotic relationship between palaeonemerteans and echinoderms. In addition, it is the first report of a symbiotic relationship between nemerteans and heart urchins, and the third known association between nemerteans and echinoderms. Numerous...
Ferns, as landplants in general, originally form a symbiosis involving Arbuscular Mycorrhizal Fungi (AMF), which are prevalent in habitats directly connected to the soil, including low epiphytic sites, but are largely absent in the high epiphytic habitat. High probabilities of AMF should be expected in chiefly terrestrial lineages whereas truly, fully adapted epiphytic lineages should be lacking fungal...
