Auxin Response Factors (ARFs) are potential mediators of auxin action in tomato response to biotic and abiotic stress (Solanum lycopersicum)

PLoS ONE, 2018
Survival biomass production and crop yield are heavily constrained by a wide range of environmental stresses. Several phytohormones among which abscisic acid (ABA), ethylene and salicylic acid (SA) are known to mediate plant responses to these stresses ...

Melatonin acts synergistically with auxin to promote lateral root development through fine tuning auxin transport in Arabidopsis thaliana.

PLoS ONE, 2019
Melatonin (N-acetyl-5-methoxytryptamine) plays important roles in plant developmental growth, especially in root architecture. The similarity in both chemical structure and biosynthetic pathway suggests a potential linkage between melatonin and auxin ...

Meta-regulation of Arabidopsis Auxin Responses Depends on tRNA Maturation

Cell Reports, 2015
Polar transport of the phytohormone auxin throughout plants shapes morphogenesis and is subject to stringent and specific control. Here, we identify basic cellular activities connected to translational control of gene expression as sufficient to specify ...

BAF60/SWP73 subunits define subclasses of SWI/SNF chromatin remodelling complexes in Arabidopsis

New Phytologist, EarlyView.
Summary Evolutionarily conserved switch‐defective/sucrose nonfermentable (SWI/SNF) ATP‐dependent chromatin remodelling complexes (CRCs) alter nucleosome positioning and chromatin states, affecting gene expression to regulate important processes such as proper development and hormonal signalling pathways.

The roles of auxin during interactions between bacterial plant pathogens and their hosts.

Journal of Experimental Botany, 2018
Plant pathogens have evolved several strategies to manipulate the biology of their hosts to facilitate colonization, growth to high levels in plant tissue, and production of disease.

B4 Raf‐like MAPKKK RAF24 regulates Arabidopsis thaliana flowering time through HISTONE MONO‐UBIQUITINATION 2

New Phytologist, EarlyView.
Summary The timing of flowering is a critical agronomic trait governed by an extensive and sophisticated regulatory network. To date, limited understanding of how posttranslational modifications regulate flowering time exists. Here, using Arabidopsis, we resolve a role for the B4 Raf‐like MAPKKK protein kinase RAF24 in regulating flowering time.

Roles for IBA-derived auxin in plant development.

Journal of Experimental Botany, 2018
The plant hormone auxin is a central regulator of plant growth and development. Because auxin plays critical roles in cell division and cell expansion, plants use a number of cellular mechanisms to regulate auxin levels and response.

Characterization of wheat oligo-tiller mutant ot2 and fine mapping of the mutant gene Taot2. [PDF]

Plant Genome
Abstract Tiller number is a crucial determinant of grain yield in wheat (Triticum aestivum L.), and identifying functional alleles can enhance our understanding of wheat tiller development. Here, we describe the ot2 wheat mutant, which exhibits a 91% reduction in tiller number compared to the wild type and displays inhibited tiller bud differentiation ...

Auxin metabolism

Physiologia Plantarum, 1997
Auxin metabolism encompasses transport, conjugation, deconjugation, conversion, and catabolism. The balance between auxin metabolism and biosynthesis determines the actual level of the hormone in a given cell and consequently plays an important role in many developmental processes from seed germination to fruit ripening.
