Growth-promoting action of simazine and other s-triazine herbicides was detected by the use of sorghum (Sorghum bicolor [L]. Moench) callus tissue and the chlorophyll retention test. Soil application of simazine [2-chloro-4, 6-bis(ethylamino)-s-triazine] at sublethal levels nearly doubled the growth-promoting action of sorghum root exudates. Treated plants yielded up to 26% more total protein t...

Studies highlighting the colonization and plant growth-promoting ability of endophytic bacteria inoculated into nonnative plant hosts reviewed and presented in this chapter. Endophytic bacteria, especially those related to the genus Bacillus, Burkholderia, Enterobacter, Gluconacetobacter, Herbaspirillum, Paenibacillus, Pseudomonas have been reported to form endophytic colonies in roots and shoo...

The use of plant growth promoting bacterial inoculants as live microbial biofertilizers provides a promising alternative to chemical fertilizers and pesticides. Inorganic phosphate solubilization is one of the major mechanisms of plant growth promotion by plant associated bacteria. This involves bacteria releasing organic acids into the soil which solubilize the phosphate complexes converting t...

Background: Breast milk is an ideal source of nutrition for growth and development of infants and has unique physiologic and emotional impacts on the health of mothers and infants. However, a few numbers of infants get exclusive breast milk and therefore, it is necessary to identify barriers to breastfeeding. The purpose of the present qualitative research was to explore challenges and barriers...

Aerobic spore-forming bacteria, such as Bacillus spp., Paenibacillus spp., and Brevibacillus spp., are one of the major soil bacteria (1, 2, 15). This finding is based on the culture-dependent methods. The culture-independent methods have also revealed that Bacillus spp. constitute a majority of the bacteria in a Dutch soil (6) and a soil contaminated with chlorinated compounds in Taiwan (3). I...

Here, we present the genome sequence of Enterobacter cloacae GS1. This strain proficiently colonizes rice roots and promotes plant growth by improving plant nutrition. Analyses of the E. cloacae GS1 genome will throw light on the genetic factors involved in root colonization, growth promotion, and ecological success of this rhizobacterium.

Arthrobacter koreensis 5J12A is a desiccation-tolerant organism isolated from the Nerium oleander rhizosphere. Here, we report its genome sequence, which may shed light on its role in plant growth promotion. This is believed to be the first published genome of a desiccation-tolerant plant growth promoter from the genus Arthrobacter.

Methylobacterium species colonize plant surfaces and utilize methanol emitted from plants. Methylobacterium aquaticum strain 22A was isolated from a hydroponic culture of a moss, Racomitrium japonicum, and is a potent plant growth promoter. The complete genome sequencing of the strain confirmed the presence of genes related to plant growth promotion and methylotrophy.

Ochrobactrum intermedium strain SA148 is a plant growth-promoting bacterium isolated from sandy soil in the Jizan area of Saudi Arabia. Here, we report the 4.9-Mb draft genome sequence of this strain, highlighting different pathways characteristic of plant growth promotion activity and environmental adaptation of SA148.
