The genus Chrysellampus Semenov, 1932 is revalidated. Chinese species are revised and keyed for the first time. Five species are recorded, two of them are new for science: Chrysellampus obtusidentibus Rosa, Wei & Xu, sp. nov. (Yunnan), and C. proximocellis Rosa, Wei & Xu, sp. nov. (Gansu and Yunnan). New synonymy for Chrysellampus Semenov, 1932 (=Parellampus Semenov, 1932, syn. nov.) and new co...

The present study describes the wood microstructure of Azima tetracantha, Salvadora oleoides, and S. persica, the members of family Salvadoraceae represented in the Indian Subcontinent. An identification key based on wood anatomical features has been developed for the separation of the species. SEM studies revealed the presence of vesturing in intervessel pits of Salvadora.

The goal of the ROSA project is to develop a variableautonomy architecture to support ground-based control of space-deployed robotic systems in dynamic workspace environments. This capability is aimed at unmanned satellite servicing systems that must rendezvous with, capture and service free flying objects. As data communication limitations force the system to perform free flyer capture autonom...

Endophytes are fungi that cause asymptomatic infections in leaves and stems of healthy plants. This study evaluated the presence of endophytic fungi on leaves of Rosa hybrida collected in Bogota, (Colombia) using histological techniques and light microscopy. Histological preparations showed fungal mycelium with few cells in the vascular tissue. Colonization of mesophyll cells was not observed. ...

Responses of plant traits to climate changes are complex, which could be mirrored by the investigations of herbarium specimens. By examining specimens of Rosa and Cotoneaster species collected since 1920s in Hengduan Mountains, we analyzed the changes of flowering phenology and flower size in the past century when climate changes were considered to be intensified. We found that flowering phenol...

Rust fungi in the genus Phragmidium are frequent pathogens of both wild and cultivated roses. We investigated the occurrence and relationships of rusts on dog roses, Rosa sect. Caninae (Rosa canina, R. corymbifera and R. rubiginosa) in Germany. Two Phragmidium species, P. mucronatum and P. tuberculatum, were able to infect each of the three dog rose species examined. However, the overall infect...

The Chinese species of the genus Philoctetes Abeille de Perrin, 1879 are revised and keyed for the first time. Six species are recorded, of which two are new for science: Philoctetes longiflagellis Rosa, Wei & Xu, sp. nov. (Inner Mongolia and Shanxi) and P. simulator Rosa, Notton & Xu, sp. nov. (Tianjin). The new synonym, Philoctetes cupratus (Mócsary, 1914), syn. nov. of Philoctetes mongolicus...

Salinity-induced modulations in growth, photosynthetic pigments, relative water content (RWC), lipid peroxidation, photosynthesis, photosystem II efficiency, and changes in activity of various antioxidative enzymes were studied in the halophyte Salvadora persica treated with various levels of salinity (0, 250, 500, 750, and 1000 mM NaCl) to obtain an insight into the salt tolerance ability of t...
