Hieracium sinoaestivum Sennikov sp. nov. is described as new to science and illustrated. This presumably apomictic species is solely known from two old collections made in a single locality in the Shanxi Province of China. It belongs to the hybridogenous group Hieracium sect. Aestiva (Hieracium sect. Prenanthoidea × Hieracium sect. Umbellata) and is most similar to Hieracium veresczaginii from ...

Seven new cytotoxic xenicane-type diterpenoids, 9-deoxyxeniloide-E (1), 9-deoxy-7,8-epoxyxeniloide-E (2), xeniolide-G (3), 9-deoxyxenialactol-C (4), xenibecin (5), xeniolide-H (6), and xenitacin (7), were isolated from the methylene chloride solubles of the Formosan soft coral Xenia umbellata. The structures were elucidated by 1D and 2D NMR spectral analysis, and their cytotoxicity against sele...

Cercospora leaf spots is one of the major foliar diseases urdbean (Vigna mungo (L.) Hepper) causing a considerable yield loss. Screening germplasm and induction mutation has not yielded any source resistance. Hence, an experiment was conducted at research farm CSKHPKV Palampur, Himachal Pradesh during 2017–21 for introgression disease resistance in urdbean. A total 45 interspecific cross combin...

Foliar endophytic fungi live inside healthy plant leaves, and in some cases they confer herbivore resistance to the host. All previous studies of endophyte–herbivore interactions have occurred in temperate areas, and many use correlations rather than experiments. In Panama, Glomerella cingulata is a common endophyte species found in healthy leaves, and Chelymorpha alternans is a common herbivor...
