Altered Expression of Two Small Secreted Proteins ( and ) Affects the Degradation of a Natural Lignocellulosic Substrate by .

is a white-rot fungus that can degrade lignin in a preferential manner using a variety of extracellular enzymes, including manganese and versatile peroxidases (encoded by the and genes, respectively). This fungus also secretes a family of structurally related small secreted proteins (SSPs) encoded by the genes. Using RNA sequencing (RNA-seq), we determined that and are the predominant members of this gene family that were expressed by during the first three weeks of growth on wheat straw.

Spike Formation Is a Turning Point Determining Wheat Root Microbiome Abundance, Structures and Functions.

Root selection of their associated microbiome composition and activities is determined by the plant's developmental stage and distance from the root. Total gene abundance, structure and functions of root-associated and rhizospheric microbiomes were studied throughout wheat growth season under field conditions. On the root surface, abundance of the well-known wheat colonizers and decreased and increased, respectively, during spike formation, whereas abundance of was independent of spike formation.

Pairwise Interactions of Three Related Species in Plant Roots and Inert Surfaces.

Bacteria are social organisms that interact extensively within and between species while responding to external stimuli from their environments. Designing synthetic microbial communities can enable efficient and beneficial microbiome implementation in many areas. However, in order to design an efficient community, one must consider the interactions between their members.

Elevated CO and nitrate levels increase wheat root-associated bacterial abundance and impact rhizosphere microbial community composition and function.

Elevated CO stimulates plant growth and affects quantity and composition of root exudates, followed by response of its microbiome. Three scenarios representing nitrate fertilization regimes: limited (30 ppm), moderate (70 ppm) and excess nitrate (100 ppm) were compared under ambient and elevated CO (eCO, 850 ppm) to elucidate their combined effects on root-surface-associated bacterial community abundance, structure and function. Wheat root-surface-associated microbiome structure and function, as well as soil and plant properties, were highly influenced by interactions between CO and nitrate levels.
