Stem microanatomical phenomic uncovers a potential role for ZmLSM2 in regulating maize stem bending strength

Journal of Integrative Plant Biology, EarlyView.
Maize ZmLSM2 (U6 small nuclear ribonucleoprotein specific Sm‐like 2) controls maize stem strength by affecting vascular bundle structure. Using advanced computed tomography imaging and artificial intelligence identified key stem traits linked to lodging resistance and developed a predictive model.

On the astronomical origin of the Hallstatt oscillation found in radiocarbon and climate records throughout the Holocene

, 2016
An oscillation with a period of about 2100-2500 years, the Hallstatt cycle, is found in cosmogenic radioisotopes (C-14 and Be-10) and in paleoclimate records throughout the Holocene. Herein we demonstrate the astronomical origin of this cycle.

Post-embryonic organogenesis and plant regeneration from tissues: two sides of the same coin? [PDF]

, 2014
Plants have extraordinary developmental plasticity as they continuously form organs during post-embryonic development. In addition they may regenerate organs upon in vitro hormonal induction.

Pathogenic fungus Ustilago maydis exploits the lateral root regulators to induce pluripotency in maize shoots

New Phytologist, EarlyView.
Summary Biotrophic plant–pathogens secrete effector molecules to redirect and exploit endogenous signaling and developmental pathways in their favor. The biotrophic fungus Ustilago maydis causes galls on all aerial parts of maize. However, the responsible gall‐inducing effectors and corresponding plant signaling pathway(s) remain largely unknown.

Partial Resistance of Medicago truncatula to Aphanomyces euteiches Is Associated with Protection of the Root Stele and Is Controlled by a Major QTL Rich in Proteasome-Related Genes

Molecular Plant-Microbe Interactions, 2009
A pathosystem between Aphanomyces euteiches, the causal agent of pea root rot disease, and the model legume Medicago truncatula was developed to gain insights into mechanisms involved in resistance to this oomycete.

Strigolactones suppress adventitious rooting in Arabidopsis and pea [PDF]

, 2012
Adventitious root formation is essential for the propagation of many commercially important plant species and involves the formation of roots from nonroot tissues such as stems or leaves.

Discrete and cell‐specific hypoxic responses in Arabidopsis roots resolved by single‐nuclei transcriptomics

New Phytologist, EarlyView.
Summary With the intensification of unpredictable flooding events because of global warming, there is a need to understand how root cells perceive and respond to oxygen deprivation. The use of high‐throughput single‐nuclei RNA‐sequencing (snRNA‐Seq) allows the examination of gene expression profiles in discrete cell types.

Root tip excision‐induced exodermis lignification impacts lateral root emergence in Brachypodium distachyon

New Phytologist, EarlyView.
Summary The mechanisms controlling lateral root emergence in monocots, particularly the role of the exodermis, are poorly understood. We investigated how natural variation in the Brachypodium distachyon stress response shapes root system architecture by modulating cell wall dynamics.

The development of hyperhydric tissue on the stems of Sambucus nigra L.

Acta Societatis Botanicorum Poloniae, 2014
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.
