Auxin and epigenetic regulation of SKP2B, an F-box that represses lateral root formation [PDF]

, 2012
In plants, lateral roots originate from pericycle founder cells that are specified at regular intervals along the main root. Here, we show that Arabidopsis (Arabidopsis thaliana) SKP2B (for S-Phase Kinase-Associated Protein2B), an F-box protein ...

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.

Strigolactones spatially influence lateral root development through the cytokinin signaling network [PDF]

, 2015
Strigolactones are important rhizosphere signals that act as phytohormones and have multiple functions, including modulation of lateral root (LR) development.

Spatiotemporal regulation of lateral root organogenesis in Arabidopsis by cytokinin [PDF]

, 2012
The architecture of a plant's root system, established postembryonically, results from both coordinated root growth and lateral root branching. The plant hormones auxin and cytokinin are central endogenous signaling molecules that regulate lateral root ...

De novo stolon organogenesis in potato leaf callus elicited by Agrobacterium tumefaciens stimulus

Journal of Integrative Plant Biology, EarlyView.
Agrobacterium tumefaciens triggers stolon regeneration from potato leaf callus independent of T‐DNA insertion, suggesting a strategy to reprogram callus identity and expand the potential of tissue regeneration. ABSTRACT Plant cells can undergo cellular reprogramming, enabling pluripotent callus formation from excised leaves.

SlGRF1 mediates gibberellin signaling to control cut‐budding in tomato

Journal of Integrative Plant Biology, EarlyView.
Upon wounding, cytokinin increases to initiate callus formation. Gibberellin enhances this, but later blocks bud formation by suppressing SlGRF1. Wounding‐induced protein SlGRF1 triggers buds via NAM1, EPF4, and ER2. Hormonal shifts control cut‐budding phases.

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.

COCHLEATA controls spatial regulation of cytokinin and auxin during nodule development

New Phytologist, EarlyView.
Nodule development defects in the coch mutant include root‐like structures, reduced colonisation, and vascular disorganisation. Summary Root nodules host nitrogen‐fixing bacteria and likely evolved through modifications of the lateral root program. Members of the NOOT‐BOP‐COCH‐LIKE transcriptional coregulator family suppress root identity in nodules ...

Synthetic Raphanobrassica Genome Reveals Functional and Evolutionary Insights Into Clubroot Resistance Genes on Chromosome R5

Plant Biotechnology Journal, EarlyView.
ABSTRACT Clubroot, a severe soil‐borne disease caused by Plasmodiophora brassicae, poses a severe threat to global production of Brassicaceae oilseed crops and vegetables. To date, there has been a serious lack of clubroot‐resistant germplasms in Brassica napus (AACC), necessitating the urgent development of novel disease‐resistant germplasm.
