Phyllotaxis, Pushed Pattern-Forming Fronts and Optimal Packing [PDF]

, 2013
We demonstrate that the pattern forming partial differential equation derived from the auxin distribution model proposed by Meyerowitz, Traas and others gives rise to all spiral phyllotaxis properties observed on plants. We show how the advancing pushed pattern front chooses spiral families enumerated by Fibonacci sequences with all attendant self ...

Regeneration ability and genetic transformation of root type chicory (Cichorium intybus var. sativum) [PDF]

, 2012
To develop an efficient protocol for shoot regeneration of root chicory (Cichorium intybus var. sativum), some factors, including different concentrations of plant growth regulators in Murashige and Skoog (MS) medium, type of explants and genotypes were ...

Experimental and Theoretical Studies on Reaction Kinetics, Mechanism, and Degradation of Quinoline‐Based Herbicide with Hydroxyl Radical, Sulphate Radical Anion, and Hydrated Electron

ChemPhysChem, EarlyView.
Advanced oxidative process is commonly used for the degradation/removal of herbicides from soil/water bodies. It mostly involves oxidizing •OH and SO4•−$\text{SO}_{4}^{\cdot -}$ species. The present study involves an experimental and theoretical approach to explore kinetics, mechanism, and degradation pathways for 8–quinoline carboxylic acid (8QCA ...

A HST1‐like gene controls tiller angle through regulating endogenous auxin in common wheat

Plant Biotechnology Journal, Volume 21, Issue 1, Page 122-135, January 2023., 2023
TaHST1L interacting with TaIAA17 controls wheat tiller angle to affect grain yield through regulating endogenous auxin. Summary Tiller angle is one of the most important agronomic traits and one key factor for wheat ideal plant architecture, which can both increase photosynthetic efficiency and greatly enhance grain yield. Here, a deacetylase HST1‐like

Rewiring of the seed metabolome during Tartary buckwheat domestication

Plant Biotechnology Journal, Volume 21, Issue 1, Page 150-164, January 2023., 2023
Summary Crop domestication usually leads to the narrowing genetic diversity. However, human selection mainly focuses on visible traits, such as yield and plant morphology, with most metabolic changes being invisible to the naked eye. Buckwheat accumulates abundant bioactive substances, making it a dual‐purpose crop with excellent nutritional and ...

Pattern formation in auxin flux [PDF]

arXiv, 2011
The plant hormone auxin is fundamental for plant growth, and its spatial distribution in plant tissues is critical for plant morphogenesis. We consider a leading model of the polar auxin flux, and study in full detail the stability of the possible equilibrium configurations.

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.

Modulation of rhizosphere microbiota by Bacillus subtilis R31 enhances long‐term suppression of banana Fusarium wilt

iMetaOmics, EarlyView.
This study indicated that biocontrol bacterium B. subtilis R31 is likely to prevent and control banana Fusarium wilt through regulating the structure and function of banana rhizosphere microorganism flora (especially increasing the microbial abundance of Actinomyces), and help potential biocontrol bacteria grow into the plant roots.
