TLDR
In this paper, a review of the role of PSM in the management of ornamental diseases is discussed and considered and several PSM for future researches aiming to improve the health and quality of ornamentals grown in different production systems.Abstract:
Ornamental plants play an important role in human society since flowers are considered a vital component due to their beauty, texture, color, shape and fragrance. To produce high quality ornamentals, growers in general have intensified the use of agrochemicals without considering their deleterious impact on floral attributes. Also, the agrochemicals (including fertilizers and pesticides) used in floriculture are expensive and their excessive application results in emergence of pathogens resistant to such chemicals. It has, therefore, become imperative to develop renewable, inexpensive and eco-friendly fertilizers without producing any disturbing impact on quality of ornamentals. In this regard, phosphate solubilizing microorganisms (PSM) among plant growth promoting rhizobacteria have been identified as an efficient alternative to agrochemicals in floriculture. Even though, there are adequate reports on the effect of PSM on growth and development of numerous plants, information on the impact of PSM on production and quality of ornamental plants is, however, critically scarce. Considering these gaps and success of PSM application in floriculture achieved so far, efforts have been directed to highlight the impact of PSM on the production of ornamentals grown distinctively in different production systems. Also, the role of PSM in the management of ornamental diseases is discussed and considered. The review will conclude by identifying several PSM for future researches aiming to improve the health and quality of ornamentals grown in different production systems. Use of PSM is also likely to reduce the use of chemicals in floriculture.read more

TL;DR: Functional analysis revealed that differentially expressed miRNAs were enriched in hypoxia-related pathways, such as the HIF-1α signaling pathways, the insulin signaling pathway, the PI3K-Akt pathway, nucleotide excision repair, cell cycle, apoptosis and fatty acid metabolism, which indicated the important roles of miRNAAs in high altitude adaptation.

Effects of waterlogging stress on the physiological response and grain-filling characteristics of spring maize (Zea mays L.) under field conditions
TL;DR: A field experiment was implemented to discuss the effects of waterlogging and subsurface water-logging stress on the grain yield, grain-filling characteristics, superoxide anion content, hydrogen peroxide content, malondialdehyde (MDA) content, antioxidant enzyme activity, proline, soluble protein content and SPAD value of the spring maize (Zea mays L.) hybrids "Demeiya1" (DMY1) and "Keyu16" (KY16) as discussed by the authors.

Herbivory in relation to plant nitrogen content
TL;DR: The evidence that N is scarce and perhaps a limiting nutrient for many herbivores, and that in response to this selection pressure, many Herbivores have evolved specific behavioral, morphological, physiological, and other adaptations to cope with and uti lize the ambient N levels of their normal haunts is examined.

Plant growth promoting rhizobacteria as biofertilizers
TL;DR: This review focuses on the known, the putative, and the speculative modes-of-action of PGPR, which include fixing N2, increasing the availability of nutrients in the rhizosphere, positively influencing root growth and morphology, and promoting other beneficial plant–microbe symbioses.

Enhanced plant growth by siderophores produced by plant growth-promoting rhizobacteria
TL;DR: Evidence is presented that PGPR exert their plant growth-promoting activity by depriving native microflora of iron by producing extracellular siderophores (microbial iron transport agents) which efficiently complex environmental iron, making it less available to certain nativemicroflora.
