Understanding Phytomicrobiome: A Potential Reservoir for Better Crop Management

Abstract

<jats:p>Recent crop production studies have aimed at an increase in the biotic and abiotic tolerance of plant communities, along with increased nutrient availability and crop yields. This can be achieved in various ways, but one of the emerging approaches is to understand the phytomicrobiome structure and associated chemical communications. The phytomicrobiome was characterized with the advent of high-throughput techniques. Its composition and chemical signaling phenomena have been revealed, leading the way for “rhizosphere engineering”. In addition to the above, phytomicrobiome studies have paved the way to best tackling soil contamination with various anthropogenic activities. Agricultural lands have been found to be unbalanced for crop production. Due to the intense application of agricultural chemicals such as herbicides, fungicides, insecticides, fertilizers, etc., which can only be rejuvenated efficiently through detailed studies on the phytomicrobiome component, the phytomicrobiome has recently emerged as a primary plant trait that affects crop production. The phytomicrobiome also acts as an essential modifying factor in plant root exudation and vice versa, resulting in better plant health and crop yield both in terms of quantity and quality. Not only supporting better plant growth, phytomicrobiome members are involved in the degradation of toxic materials, alleviating the stress conditions that adversely affect plant development. Thus, the present review compiles the progress in understanding phytomicrobiome relationships and their application in achieving the goal of sustainable agriculture.</jats:p>

Quorum Quenching in a Novel Acinetobacter sp. XN-10 Bacterial Strain against Pectobacterium carotovorum subsp. carotovorum

“…QQ is a method for interrupting QS and can be achieved in many different pathways. QQ has recently been recognized as a novel and potential strategy for disease control in aquaculture, agriculture, and human healthcare [ 42 , 43 , 44 , 45 ]. Theoretically, there are many ways to achieve QQ; however, certain methods are not feasible.…”

Phytoremediation of Cadmium Contaminated Soil Using Sesbania sesban L. in Association with Bacillus anthracis PM21: A Biochemical Analysis

“…In the same way, physiological parameters proline (37.75%) and MDA contents (34.84%) were decreased in S. sesban when exposed to Cd [38]. Cadmium stress produced ROS that led to plant oxidative stress with increased ELL and lipid peroxidation [71]. Malondialdehyde content is an indication of cell membrane damage due to its reaction with protein amino groups [25].…”

Plant Holobiont Theory: The Phytomicrobiome Plays a Central Role in Evolution and Success

“…For coevolution to occur within a holobiome, both the host and the microbiome must evolve in response to the same environmental pressure(s). This coevolution has resulted in the establishment of complex signaling pathways and feedback loops that use phyto- and microbial-derived compounds to achieve functional regulation of the plant holobiont [ 83 ]. For example, root exudates recruit beneficial microbes that release compounds, such as the phytohormone IAA, that promote plant growth and encourage the release of more root exudates, thereby promoting holobiont success [ 84 ].…”
