Cytokinins are involved in drought tolerance of Pinus radiata plants originating from embryonal masses induced at high temperatures
Vegetative propagation through somatic embryogenesis is an effective method to produce elite varieties and can be applied as a tool to study the response of plants to different stresses. Several studies show that environmental ... -
Elevated CO2 improved the growth of a double nitrate reductase defective mutant of Arabidopsis thaliana: the importance of maintaining a high energy status
Impairments in leaf nitrogen (N) assimilation in C3 plants have been identified as processes conditioning photosynthesis under elevated [CO2], especially when N is supplied as nitrate. Leaf N status is usually improved ... -
Estimating peanut and soybean photosynthetic traits using leaf spectral reflectance and advance regression models
One proposed key strategy for increasing potential crop stability and yield centers on exploitation of genotypic variability in photosynthetic capacity through precise high-throughput phenotyping techniques. Photosynthetic ... -
Overexpression of plastidial thioredoxins f and m differentially alters photosynthetic activity and response to oxidative stress in tobacco plants
Plants display a remarkable diversity of thioredoxins (Trxs), reductases controlling the thiol redox status of proteins. The physiological function of many of them remains elusive, particularly for plastidial Trxs f and ... -
Overexpression of thioredoxin m in tobacco chloroplasts inhibits the protein kinase STN7 and alters photosynthetic performance
The activity of the protein kinase STN7, involved in phosphorylation of the light-harvesting complex II (LHCII) proteins, has been reported as being co-operatively regulated by the redox state of the plastoquinone pool ... -
Photoselective shade films mitigate heat wave damage by reducing anthocyanin and flavonol degradation in grapevine (vitis vinifera L.) berries
Wine grape production is challenged by forecasted increases in air temperature and droughts due to climate change and photoselective overhead shade films are promising tools in hot viticulture areas to overcome climate ... -
Photosynthetic metabolism under stressful growth conditions as a bases for crop breeding and yield improvement
Increased periods of water shortage and higher temperatures, together with a reduction in nutrient availability, have been proposed as major factors that negatively impact plant development. Photosynthetic CO2 assimilation ... -
Proteomics analysis reveals non-controlled activation of photosynthesis and protein synthesis in a rice npp1 mutant under high temperature and elevated CO2 conditions
Rice nucleotide pyrophosphatase/phosphodiesterase 1 (NPP1) catalyzes the hydrolytic breakdown of the pyrophosphate and phosphodiester bonds of a number of nucleotides including ADP-glucose and ATP. Under high temperature ... -
Regulación postraduccional de la respuesta de las plantas a volátiles emitidos por hongos fitopatógenos
Con el fin de profundizar en los mecanismos que median la relación entre la planta y los microorganismos, en este trabajo investigué el papel que juegan dos formas de regulación postraduccional en la respuesta de las plantas ... -
Regulation of the response of plants to volatile compounds emitted by fungal phytopathogens
El crecimiento y el desarrollo de las plantas están afectados por microorganismos presentes en la filosfera, la rizosfera y/o la endosfera. En la fase de precolonización, antes de que se establezca un contacto físico con ... -
Unraveling the role of transient starch in the response of Arabidopsis to elevated CO2 under long-day conditions
Previous studies on Arabidopsis under long-term exposure to elevated CO2 have been conducted using starch synthesis and breakdown mutants cultured under short day conditions. These studies showed that starch synthesis can ... -
Volatile compounds emitted by diverse phytopathogenic microorganisms promote plant growth and flowering through cytokinin action
It is known that volatile emissions from some beneficial rhizosphere microorganisms promote plant growth. Here we show that volatile compounds (VCs) emitted by phylogenetically diverse rhizosphere and non-rhizhosphere ... -
Volatile compounds other than CO2 emitted by different microorganisms promote distinct posttranscriptionally regulated responses in plants
A 'box-in-box' cocultivation system was used to investigate plant responses to microbial volatile compounds (VCs) and to evaluate the contributions of organic and inorganic VCs (VOCs and VICs, respectively) to these ...
