Hypocotyl adventitious root organogenesis differs from lateral root development [PDF]
Wound-induced adventitious root (AR) formation is a requirement for plant survival upon root damage inflicted by pathogen attack, but also during the regeneration of plant stem cuttings for clonal propagation of elite plant varieties.

Spatial Regulation of Silicon Accumulation in Peduncle Confers Sheathed Spike in Barley
ABSTRACT Peduncle, the uppermost internode in cereals, connects the stem to the inflorescence and is critical for the transport of water, nutrients and photosynthetic assimilates. While peduncle length associates with plant height and its elongation is primarily regulated by phytohormones, we report a previously unrecognized mechanism involving the ...

The development of hyperhydric tissue on the stems of Sambucus nigra L.
Hyperhydric intumescences on the stems of Sambucus nigra arise in places where the stem lenticels are immersed in water. The hyperhydric tissue develops through the transformation of the multilayered phelloderm, the parenchyma of the cortex.

Changes in gene expression in space and time orchestrate environmentally mediated shaping of root architecture [PDF]
Shaping of root architecture is a quintessential developmental response that involves the concerted action of many different cell types, is highly dynamic and underpins root plasticity.

Pericyclic reactions in ether biofuels [PDF]
Unimolecular decompositions of acyclic ethers through a pericyclic mechanism, i.e., alcohol elimination, have been shown to play a crucial role in the high-temperature combustion of these compounds. The production of new fuels derived from biomass has led to a renewed interest into the combustion chemistry of ethers. A large fraction of ethers produced

Proposed model of TAC1‐mediated leaf angle regulation in tobacco. ABSTRACT Plant architecture is key to crop yield, with leaf angle being critical for high‐density cultivation. Although TAC1 represents a promising regulator of leaf angle for breeding, its molecular mechanism remains poorly understood, particularly at single‐nucleus resolution. Here, we

WeiTsing: a new face of Ca2+-permeable channels in plant immunity
Plants employ pattern- and effector-triggered immunity (PTI and ETI) to synergistically defend invading pathogens and insect herbivores. Both PTI and ETI can induce cytosolic Ca2+ spikes, despite in different spatiotemporal patterns, to activate ...

Manipulation of auxin transport in plant roots during Rhizobium symbiosis and nematode parasitism [PDF]
The plant rhizosphere harbors many different microorganisms, ranging from plant growth-promoting bacteria to devastating plant parasites. Some of these microbes are able to induce de novo organ formation in infected roots.

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...
