Hairy roots formation in recalcitrant-to-transform plant Chenopodium rubrum

, 2010
Susceptibility of C. rubrum to Agrobacterium-mediated transformation was demonstrated by inoculating the petioles of in vitro grown plants with A. rhizogenes strain A4M70GUS. Hairy roots were produced in 8 % of explants. They were isolated and maintained

Temporal changes in carboxylate content of ryegrass with stepwise change in nutrition [PDF]

, 1968
A detailed scheme of carboxylate formation and retention by plant tissues as a result of ion uptake and utilization is given. By means of discontinuities in the supply with nutrient ions, carboxylate retention by the tissues of perennial ryegrass was ...

Effects of soil water on fungal community composition along elevational gradients on the northern slope of the Central Kunlun Mountains

Frontiers in Microbiology
Soil fungi are essential to ecosystem processes, yet their elevational distribution patterns and the ecological mechanisms shaping their communities remain poorly understood and actively debated, particularly in arid regions.

Roots Mediate the Effects of Snowpack Decline on Soil Bacteria, Fungi, and Nitrogen Cycling in a Northern Hardwood Forest

Frontiers in Microbiology, 2019
Rising winter air temperature will reduce snow depth and duration over the next century in northern hardwood forests. Reductions in snow depth may affect soil bacteria and fungi directly, but also affect soil microbes indirectly through effects of ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The effect of the duration of hypoxia on the activity of peroxidase, superoxide dismutase and catalase in the roots of clonal Eucalyptus marginata [PDF]

, 1997
Roots of E. marginata exposed to hypoxia show increased resistance to infection by P. cinnamomi. A plant defence enzyme, peroxidase (PO), involved in lignin and suberin synthesis, the clearance of hydrogen peroxide and the cross-linking of cell wall ...

Toward a Molecular Understanding of Plant Hormone Actions [PDF]

, 2016
Plants rely on a diverse set of small-molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone, auxin, hormones have always been at the frontier

Root Architecture and Plant Productivity [PDF]

Plant Physiology, 1995
Water and nutrient availability limit plant growth in a11 but a very few natural ecosystems. They limit yield in most agricultural ecosystems, and in the United States and other industrialized nations, intensive irrigation and fertilization have generated serious environmental problems.

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
