Reducing ethylene sensitivity by modifying the expression of a negative regulator of ethylene signal transduction improves grain yield in maize under drought stress environments. Lack of sufficient water is a major limiting factor to crop production worldwide, and the development of drought-tolerant germplasm is needed to improve crop productivity. The phytohormone ethylene modulates plant growth and development as well as plant response to abiotic stress. Recent research has shown that…

Ectopic expression of ARGOS8 reveals a role for ethylene in root‐lodging resistance in maize
Summary Ethylene plays a critical role in many diverse processes in plant development. Recent studies have demonstrated that overexpression of the maize ARGOS8 gene reduces the plant's response to

It is demonstrated that ZmXerico1 plays a role in the control of ABA homeostasis through regulation of A BA 8′-hydroxylase protein stability, representing a novel control point in the regulation of the ABA pathway.
A Functional Genomic Perspective on Drought Signalling and its Crosstalk with Phytohormone-mediated Signalling Pathways in Plants
The molecular mechanism of drought signalling and its crosstalk with various phytohormone signalling pathways implicated in abiotic stress response and tolerance is summarized.
Maize and Arabidopsis ARGOS Proteins Interact with Ethylene Receptor Signaling Complex, Supporting a Regulatory Role for ARGOS in Ethylene Signal Transduction[OPEN]
A physical association between ARGOS and the ethylene receptor signaling complex via AtRTE1 and maize RTL proteins is suggested, supporting a role for ARGos in regulating ethylene perception and the early steps of signal transduction in Arabidopsis and maize.
A vegetative storage protein improves drought tolerance in maize
It is demonstrated that transgenic hybrids overexpressing ZmLOX6 in the mesophyll cells significantly outyielded non-transgenic sibs under managed drought stress imposed at flowering.

Using positional cloning, an identical 334-bp deletion in a gene of unknown biochemical function at the Gr/Nr-2 locus is identified and this gene is identified as Gr, which expands the current repertoire of ethylene signaling components in plants and provides a tool for further elucidation of Ethylene response mechanisms and for controlling ethylene signal specificity in crop plants.
ETHYLENE INSENSITIVE3 and ETHYLENE INSENSITIVE3-LIKE1 Repress SALICYLIC ACID INDUCTION DEFICIENT2 Expression to Negatively Regulate Plant Innate Immunity in Arabidopsis[W][OA]
It is shown that Arabidopsis thaliana transcription factors EIN3 and EIL1, previously known to mediate ethylene signaling, also negatively regulate PAMP-triggered immunity, and evidence is provided that Ein3/EIL1 directly target SID2 to downregulate PAMP defenses.

Exploiting the triple response of Arabidopsis to identify ethylene-related mutants.
Alterations in the response of dark-grown seedlings to ethylene (the "triple response") were used to isolate a collection of ethylene-related mutants in Arabidopsis thaliana and should prove to be useful tools for dissecting the mode of Ethylene action in plants.
Constitutive expression of the ARGOS gene driven by dahlia mosaic virus promoter in tobacco plants
The auxin-inducible gene ARGOS from Arabidopsis thaliana is expressed in growing tissues and controls the plant organ size by regulating cell proliferation and meristematic competence and stability and inheritance of the transgene were demonstrated in T2 transgenic plants.
