On plants at 59 sugarcane plantations in Central and East Java, Indonesia, we found virus-like symptoms such as streak mosaic. The virus was transmitted mechanically and was sett-borne. The nucleotide sequence of the coat protein gene had the highest identity with that of Sugarcane streak mosaic virus (SCSMV) isolate Pakistani. We tentatively designate this isolate as SCSMV-Idn (Indonesia).  相似文献   

Semilunar spawning periodicity in brackish damsel Pomacentrus taeniometopon

ABSTRACT:   Lunar-related spawning periodicity of the brackish damsel Pomacentrus taeniometopon was investigated by changes in gonadosomatic index (GSI) and ovarian histology. During the spawning season, GSI increased toward the week of the first and last quarter moon. Concomitant with increases in GSI, oocytes laden with yolk developed from the new/full moon to the first/last quarter moon. Postovulatory follicles appeared in the ovary around and after the first/last quarter moon. These results suggest that P. taeniometopon is a semilunar spawner and repeats spawnings twice a month with lunar periodicity during the spawning season. When the fish were reared under laboratory conditions without periodicity of tide, the spawning of P. taeniometopon occurred sporadically. It is likely that the fish uses tidal stimuli in the natural habitat to entrain reproductive activities.  相似文献
