1. Phytopathogen resistance of phytohormone-deficient and low-sensitivity mutant tomatoes
ABSTRACT This study broadens the knowledge of plant-pathogen interactions using phytohormone-deficient and low-sensitivity mutant tomatoes. The experiment was performed under greenhouse conditions and the mutants used were provided by the HCPD laboratory, at ESALQ/USP. The hormone mutant Never ripe showed a larger final lesion size when inoculated with Botry

2. Torulaspora globosa: rhizosphere yeast promoting lettuce growth on seedlings and under field conditions
RESUMO Micro-organismos promotores de crescimento vegetal (MPCV) auxiliam as plantas pela produção de fitormônios, disponibilização de nutrientes e manutenção da sanidade vegetal. Dentre os MPCV, as leveduras apresentam grande potencial ainda inexplorado. O objetivo deste trabalho foi avaliar a inoculação da levedura rizosférica Torulaspora globos

3. Transcriptome sequencing and expression profiling of genes involved in the response to abiotic stress in Medicago ruthenica
Abstract Medicago ruthenica is a perennial forage legume with the remarkable ability to survive under unfavorable environmental conditions. It has been identified as an excellent species of Medicago that can adapt to various environmental stresses including low temperature, drought, and salinity. To investigate its potential as a genetic resource, we perform

4. Isolation and identification by 16S rRNA sequence analysis of plant growth-promoting azospirilla from the rhizosphere of wheat
ABSTRACT The main objective of the present study was to isolate phytohormone-producing, phosphate-solubilizing strains of Azospirillum from wheat to be used as inoculants for plant growth promotion. Five Azospirillum strains were isolated from the rhizosphere of field-grown wheat (Triticum aestivum L.), and it was confirmed by BOX-polymerase chain reaction (

5. Exogenous abscisic acid inhibits the water-loss of postharvest romaine lettuce during storage by inducing stomatal closure
Abstract Postharvest lettuce often lose water, thus affecting both its market value and consumer acceptance. However, the mechanism of the water-loss is still waiting well exploration. The aim of the present study was to investigate the effect of a foliar application of ABA on the fresh weight-loss and the chlorophyll content of postharvest lettuce as well a

6. Resistance to cyanide by salicylate pretreatment in Salix babylonica L.
Cyanide is uncontrollably produced in some industrial operations and has lethal effects on humans and the environment. Since removing processes of cyanide are complicated and costly, the phytoremediation has recently been extensively considered. To achieve an increased cyanide resistance, which is needed for an efficient phytoremediation of the mediums with

7. The role of matrix effects on the quantification of abscisic acid and its metabolites in the leaves of Bauhinia variegata L. using liquid chromatography combined with tandem mass spectrometry
Phytohormone analysis using liquid chromatography combined with tandem mass spectrometry is a very important tool for studies involving plant metabolism; however, this analysis can be affected by matrix composition. Although it is necessary to understand this effect to produce reliable results, it has been widely neglected in analyses of plant hormones. Leaf

8. Efecto del nitrato de potasio, fosfato de potasio y ethephon en la inducción floral de la feijoa o goiabeira serrana (Acca sellowiana [O. Berg] Burret)
The experiment was carried out in El Cortijo farm (La Vega, Cundinamarca, Colombia [ 04° 55' N and 74° 18' W ], 2350 m above sea level, 17° C average temperature, 1423 mm of annual precipitation, 85% of relative humidity, and 1.377 of sunshine hours/year). In the study, evaluation of foliar fertilizers KNO3 (potassium nitrate 13-0-46® 1%, 1.5%, and 2%),

9. In silico analysis of phytohormone metabolism and communication pathways in citrus transcriptome
Plant hormones play a crucial role in integrating endogenous and exogenous signals and in determining developmental responses to form the plant body throughout its life cycle. In citrus species, several economically important processes are controlled by phytohormones, including seed germination, secondary growth, fruit abscission and ripening. Integrative ge

10. Ethylene and fruit ripening: from illumination gas to the control of gene expression, more than a century of discoveries
The effects of ethylene on plants have been recognized since the Nineteenth Century and it is widely known as the phytohormone responsible for fruit ripening and for its involvement in a number of plant growth and development processes. Elucidating the mechanisms involved in the ripening of climacteric fruit and the role that ethylene plays in this process h
