Salicylic acid (SA), Jasmonic (JA) and ethylene (ET) have the significant roles in plants physiologically defense against pathogens. To elucidate role of these three phytohormones development Induced systemic resistance (ISR), it is a immune response that occurs when roots are colonized by beneficial microbes. The study model SRI combination specific strains Pseudomonas fluorescens PTA-CT2 with...

We have found that chromosaponin I (CSI), a gamma-pyronyl-triterpenoid saponin isolated from pea (Pisum sativum L. cv Alaska), specifically interacts with AUX1 protein in regulating the gravitropic response of Arabidopsis roots. Application of 60 microM CSI disrupts the vertically oriented elongation of wild-type roots grown on agar plates but orients the elongation of agravitropic mutant aux1-...

Auxin and ethylene are key regulators of plant growth and development, and thus the transcriptional networks that mediate responses to these hormones have been the subject of intense research. This study dissected the hormonal cross talk regulating the synthesis of flavonols and examined their impact on root growth and development. We analyzed the effects of auxin and an ethylene precursor on r...

Cultivated sunflower (Helianthus annuus L.), an important source of edible vegetable oil, shows rapid onset of senescence, which limits production by reducing photosynthetic capacity under specific growing conditions. Carbon for grain filling depends strongly on light interception by green leaf area, which diminishes during grain filling due to leaf senescence. Transcription factors (TFs) regul...

Two modes of plant immunity against biotrophic pathogens, Effector Triggered Immunity (ETI) and Pattern-Triggered Immunity (PTI), are triggered by recognition of pathogen effectors and Microbe-Associated Molecular Patterns (MAMPs), respectively. Although the jasmonic acid (JA)/ethylene (ET) and salicylic acid (SA) signaling sectors are generally antagonistic and important for immunity against n...

Ethylene is a gaseous hormone which plays important roles in both plant growth and development stress responses. Based on studies the dicot model species Arabidopsis, linear ethylene signaling pathway has been established, according to perceived by receptors transduced through CONSTITUTIVE TRIPLE RESPONSE 1 (CTR1) ETHYLENE-INSENSITIVE 2 (EIN2) activate transcriptional reprogramming. In addition...

Abstract Fruit quality in most fleshy fruit crops is fundamentally linked to ripening-associated traits, including changes colour. In many climacteric fruits, tomato (Solanum lycopersicum), the phytohormone ethylene plays a key role regulating ripening. Previous map-based cloning of YELLOW FRUITED-TOMATO 1 (YFT1) revealed that it encodes EIN2 protein, core component signal transduction. A YFT1 ...
