The G protein subunit α1, CaGα1, mediates ethylene sensing of mango anthracnose pathogen to regulate fungal development and virulence and mediates surface sensing for spore germination.

Mango is an important tropic fruit, but its production is highly restricted by anthracnose diseases. Mango anthracnose development is related to the fruit-ripening hormone ethylene, but how the pathogen senses ethylene and affects the infection remains largely unknown. In this study, mango pathogen strain TYC-2 was shown to sense ethylene to enhance spore germination, appressorium formation and virulence.

Phenolic compositions and antioxidant properties of leaves of eight persimmon varieties harvested in different periods.

The compositions and contents of antioxidant components and antioxidant attributes (scavenging DPPH radicals, TEAC, ferric reducing power and inhibiting Cu-induced human LDL oxidation) for the leaves of eight persimmon varieties harvested from Sep. to Nov. were determined.

Expression Profiles of Phosphoenolpyruvate Carboxylase and Phosphoenolpyruvate Carboxylase Kinase Genes in , Implications for Regulating the Performance of Crassulacean Acid Metabolism.

is one of the most important potted plants in the ornamental market of the world. Previous reports implied that crassulacean acid metabolism (CAM) orchids at their young seedling stages might perform C or weak CAM photosynthetic pathways, but the detailed molecular evidence is still lacking. In this study, we used a key species in white breeding line, subsp.

Re-emergence of Lilium callosum Sieb. et Zucc. in Taiwan after a fire allows propagation and renews the possibility of conservation.

Background: Lilium callosum is native to Taiwan, but little is known about it since it has been considered extinct since 1915. After the rediscovery of this rare species after a fire in 2011 in Tunghsiao Township, intensive work has been conducted to count the number in the wild population, to develop a conservation strategy, and to understand its reproductive characteristics and even economic potential.

Results: To conserve the germplasm of this population, three scales from a wild L.

Mutation of the Arabidopsis NRT1.5 nitrate transporter causes defective root-to-shoot nitrate transport.

Little is known about the molecular and regulatory mechanisms of long-distance nitrate transport in higher plants. NRT1.5 is one of the 53 Arabidopsis thaliana nitrate transporter NRT1 (Peptide Transporter PTR) genes, of which two members, NRT1.

Mutation of a nitrate transporter, AtNRT1:4, results in a reduced petiole nitrate content and altered leaf development.

Unlike nitrate uptake of plant roots, less is known at the molecular level about how nitrate is distributed in various plant tissues. In the present study, characterization of the nitrate transporter, AtNRT1:4, revealed a special role of petiole in nitrate homeostasis. Electrophysiological studies using Xenopus oocytes showed that AtNRT1:4 was a low-affinity nitrate transporter.
