Root development is maintained by specific bacteria-bacteria interactions (bioRxiv)

Understanding plant-microbe and microbe-microbe interactions is challening. Both kinds of interactions have significant impacts on plant health and nutritional uptake. Finkel et al. address how microbe-microbe interactions shape plant phenotypes by using the synthetic microbial community (SynCom) consisting of 185 bacterial members. Plants and SynCom were exposed to variable abiotic conditions such as salinity, temperature, […]

A specialized metabolic network selectively modulates Arabidopsis root microbiota (Science)

Plants have evolved to adapt to varied environmental niches. The ability to produce specialized metabolites is one of the evolved characteristics which help plants to thrive through varied biotic and abiotic conditions. Plant-associated microbes are always known to have a drastic impact on plant growth and fitness. Although, the knowledge about the factors responsible for […]

NRT1.1B is associated with root microbiota composition and nitrogen use in rice ($) (Nature Biotechnol)

Availability of nitrogen has always been a limiting factor for rice production. Different soil inhabitants and root-associated bacterial populations are involved in making nitrogen available to plants in organic as well as in inorganic forms. However, plant absorption of nitrogen is selective and affects its nitrogen use efficiency (NUE). The two main Asian cultivated rice […]

A jasmonate signaling network activates root stem cells and promotes regeneration ($) (Cell)

Plants possess plasticity for regeneration of organs after damage by physical, biotic or abiotic stress. The mitotically less-active organizer cells, quiescent center (QC) and surrounding initials form the stem cell niche, which is known to play a very important role in activation of the regeneration process in animals as well as in plants. In the […]

Cell type specific transcriptional reprogramming during Ustilago maydis and maize interaction (bioRxiv)

Ustilago maydis is a model biotrophic fungus which causes smut disesase in maize, characterized by tumorous symptoms on all aerial parts. Tumor formation in leaves of the host is a result of massive reprogramming by modulation of two processes, hypertrophy (cell expansion) and hyperplasia (cell division). Previously, it has been shown that the tumor formation […]

Membrane systems at the host-arbuscular mycorrhizal fungus interface (Nature Plants) ($)

In the arbuscular mycorrhizal fungal interaction with plants, the fungal partner promotes nutrient acquisition in exchange for some sugar and fatty acids from host plants. This exchange occurs at the symbiotic interface in the plant cortical cells where fungal hyphae form special branched structure called arbuscules, which are enveloped by host-derived peri-arbuscular membranes (PAM). Two […]

What quantity of photosystem I is optimum for safe photosynthesis? ($) (Plant Physiol)

Photosynthesis is one of the most vital and complex processes carried out by plants. During photosynthesis, Photosystem I and II (PSI and PSII) undergo photo-excitation. Excessive photo-excitation can damage and deactivate the PSI by generating reactive oxygen species (ROS). This kind of photoinhibition of PSI is a lethal event that can abruptly inhibit the photosynthesis […]

Microbial interkingdom interactions in roots promote Arabidopsis survival (Cell)

Plant roots in soil are surrounded by different microorganisms such as bacteria, fungi and oomycetes. The impact of these organisms on plant health has been known f0r many decades. However, the interaction network between these organisms is not well understood. By using next generation sequencing as a tool, Duran et al. profiled root associated multi-kingdom […]
