Blog, Plant Physiology, Plant Physiology: On The Inside, Research, Research BlogDinoflagellates in the genus Symbiodinium have the ability to enter into endosymbiotic associations with corals, providing the metabolic basis for the highly productive and biologically diverse coral-reef ecosystems, as well as with other cnidarians, including sea anemones and jellyfish. The Symbiodinium-coral…

Boron Transport in Rice
Blog, Plant Physiology, Plant Physiology: On The Inside, Research, Research BlogBoron (B) is an essential micronutrient for plant growth and development. Its major physiological function is to maintain the structure of the cell wall by crosslinking pectic polysaccharides through borate-diol bonding of two rhamnogalacturonan II molecules. B is immobile in most plant species. Therefore,…

Epigenetic Divergence Associated with Heterosis
Blog, Plant Physiology, Plant Physiology: On The Inside, Research, Research BlogHeterosis refers to the tendency of a crossbred individual to show qualities superior to those of both parents. The phenomenon has been exploited extensively in agricultural breeding for decades and has improved crop performance enormously. Despite its commercial impact, knowledge of the molecular basis…

Mineral Deposits in Ficus Leaves
Blog, Plant Physiology, Plant Physiology: On The Inside, Research, Research BlogMineral deposits occur in many, but not all plant leaves. In those leaves that do have minerals, the mineral type, morphology and the distributions within the leaves are under strict control. In fact, mineralization in certain leaves is a well-preserved trait throughout evolution, indicating that such…

Anthocyanins on Demand
Blog, Plant Physiology: On The Inside, Research, Research BlogAnthocyanins are vacuolar pigments derived from the phenylpropanoid pathway that are produced in many different plant species. The role of anthocyanin accumulation under stress in vegetative tissues is probably linked to the scavenging of reactive oxygen species (ROS). Anthocyanins are powerful antioxidants…

Laccase Confers Biotic Stress Tolerance in Cotton
Blog, Plant Physiology, Plant Physiology: On The Inside, Research, Research BlogCotton (Gossypium spp.) is a globally cultivated globally crop of vast economic importance. Pathogens and pests are major limitations to cotton yield and quality. Verticillium wilt, caused by the fungus Verticillium dahliae, is the disease most detrimental to cotton production. Cotton bollworm (Helicoverpa…

Probing the stochastic property of endoreduplication in cell size determination of Arabidopsis thaliana leaf epidermal tissue
Blog, Plant Science Research Weekly, Research, Research BlogPLOS One. Endoreduplicated cells grow in size as their DNA content increases. The distribution of size was observed to be Poisson. This allowed the authors to create a mathematical model with a single parameter which describes the probability of exiting endoreduplication. The model recovers cell size…

A mathematical model of the interaction of abscisic acid, ethylene and methyl jasmonate on stomatal closure in plants
Blog, Plant Science Research Weekly, Research, Research BlogPLOS One. Plant stomatal opening is controlled by phytohormones, among other factors. This article models the phytohormone signaling response in guard cells using ordinary differential equations (ODEs). Sixteen components in this system were analyzed by constructing 16 different models and determining…

Predicting gene regulatory networks by combining spatial and temporal gene expression data in Arabidopsis root stem cells
Blog, Plant Science Research Weekly, Research, Research BlogProc. Natl. Acad. Sci. USA. GENIST (gene regulatory network inference from spatiotemporal data) is a new algorithm developed by de Luis Balaguer et al to predict new gene interactions and transcriptional regulators (available at https://github.com/madeluis/GENIST). The algorithm combines inference of…
