Effects of Girdling and Chemical Treatments on the Response of Longan Fruit and Layer

open access: yesGuangdong nongye kexue, 2023
【Objective】The production mode of Hainan longan can be divided into natural flowering on-season longan and off-season longan induced by potassium chlorate. Reasonable fruit loading is extremely important to maintain tree vigor and avoid alternate bearing

Auxin and tryptophan homeostasis are facilitated by the ISS1/VAS1 aromatic aminotransferase in arabidopsis [PDF]

open access: yes, 2015
Indole-3-acetic acid (IAA) plays a critical role in regulating numerous aspects of plant growth and development. While there is much genetic support for tryptophan-dependent (Trp-D) IAA synthesis pathways, there is little genetic evidence for tryptophan ...

Genome-Wide Identification, Functional Analysis and Expression Profiling of the Aux/IAA Gene Family in Tomato [PDF]

open access: yes, 2012
Auxin is a central hormone that exerts pleiotropic effects on plant growth including the development of roots, shoots, flowers and fruit. The perception and signaling of the plant hormone auxin rely on the cooperative action of several components,among

Physiological and biochemical changes during graft union formation in Carya illinoinensis

open access: yesBiologia Plantarum, 2021
To reveal the physiological and biochemical mechanism underlying graft union formation in pecan (Carya illinoinensis), dynamic changes in content of nutrients, tannin, and phytohormones together with key enzyme activities were investigated 0, 3, 5, 7, 10,

Auxin regulates SCFTIR1-dependent degradation of AUX/IAA proteins [PDF]

open access: yes, 2001
The plant hormone auxin is central in many aspects of plant development. Previous studies have implicated the ubiquitin-ligase SCFTIR1 and the AUX/IAA proteins in auxin response.

Evo-SETI: A Mathematical Tool for Cladistics, Evolution, and SETI

open access: yesLife, 2017
The discovery of new exoplanets makes us wonder where each new exoplanet stands along its way to develop life as we know it on Earth. Our Evo-SETI Theory is a mathematical way to face this problem.

Indole-3-butyric acid induces ectopic formation of metaxylem in the hypocotyl of Arabidopsis thaliana without conversion into indole-3-acetic acid and with a positive interaction with ethylene [PDF]

open access: yes, 2017
The role of the auxins indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) and of the auxin-interacting phytohormone ethylene, on the ectopic formation of primary xylem (xylogenesis in planta) is still little known.

Root−to−Shoot Signaling and Leaf Water−Use Efficiency in Peach Trees under Localized Irrigation

open access: yesAgronomy, 2020
Global climate change is affecting important natural resources including water. Increasing temperature will change rate of evaporation and transpiration, leading to variations in water availability, ground water recharge, and water consumption by plants.

AXR3 and SHY2 interact to regulate root hair development [PDF]

open access: yes, 2003
Signal transduction of the plant hormone auxin centres on the regulation of the abundance of members of the Aux/IAA family of transcriptional regulators, of which there are 29 in Arabidopsis.
