Summary Morphological variation within organisms is integrated and often modular in nature. That is to say, the size and shape of traits tend to vary in a coordinated and structured manner across sets of organs or parts of an organism. The genetic basis of this morphological integration is largely unknown. Here, we report on quantitative trait loci (QTL) analysis of leaf and floral organ size i...
Shoot and inflorescence are central physiological and developmental tissues of plants. Flowering is one of the most important agronomic traits for improvement of crop yield. To analyze the vegetative to reproductive tissue transition in Jatropha curcas, gene expression profiles were generated from shoot and inflorescence tissues. RNA isolated from both tissues was sequenced using the Ilumina Hi...
The environment can influence heterosis, the phenomena in which the offspring of two inbred parents exhibits phenotypic performance beyond the inbred parents for specific traits. In this study we measured 25 traits in a set of 47 maize hybrids and their inbred parents grown in 16 different environments with varying levels of average productivity. By quantifying 25 vegetative and reproductive tr...
Inferring community assembly processes from functional seed trait variation along elevation gradient
Assembly of plant communities has long been scrutinized through the lens trait-based ecology. Studies generally analyse functional traits related to vegetative growth, survival and resource acquisition thus ignore how assembly rules may affect plants at other stages their life cycle, particularly when seeds disperse, persist in soil germinate. Here, we analysed an extensive dataset 16 for 167 s...
Ecological invasions are a major issue worldwide, where successful invasion depends on traits that facilitate dispersion, establishment, and population growth. The nonnative succulent plant Kalanchoe pinnata, reported as invasive in some countries, is widespread in remnants of seasonally dry tropical forest on a volcanic outcrop with high conservation value in east-central Mexico where we asses...
Abiotic stresses such as salinity, are factors that severely affects agricultural production. To evaluate the effects of salinity on some morphological and physiological traits related to salt tolerance of 22 genotypes of spring rapeseed cultivars in the vegetative growth stage, an experiment was conducted as a split plot form based on Randomized Complete Blocks Design using levels of salinity:...
Grain yield in wheat is influenced directly and indirectly by other plant characteristics. One of the main goals in wheat breeding programs is increase of grain yield. Considering the role of crop rotation in increasing grain yield, and in order to study the difference between crop rotations for wheat yield and yield components (Darya cultivar), an experiment was conducted with six rotation tre...
