Abstract

Cassava Brown Streak Disease (CBSD) is a major disease in cassava plants which have the serious problems in cassava plantations in the world, especially in Africa, Tanzania and India (Wassawaet., al, 2010). In Indonesia, the virus is still not optimal yet in the handling. The disease is present in plants that can destructive cassava leaves, stems and tubers.  It was greatly reduces the quality and production in the world such as India.  The decrease of cassava yield can reach 100% due to disease of CBSD (Lopez, 2003). The primer was designed from the coat protein gene of CBSD with a distance of 380 bp (Abarshiet.,al, 2012). The primers designed the forward primer (GGARCCRATGTAYAAATTTGC) and Reverse (GCWGCTTTTA  TYACAAAMGC). The RNA isolation have been used Plant Virus RNA Kit (Geneaid).  The CBSD RNA concentration around 55,2ng/ul.  The RT PCR program were one cycle of RT PCR reaction (45oC for 30 min), denaturation (45oC for 5 min) and 30 cycles for denaturation (94oC for 1 min), annealing (52oC for 30 sec), extention  (72oC for 1 min).  The results showed a single band of about 380 bp which is the  distance between the two primers were tested.  The multiplication shoot around 5 shoots per meristem explants with a combination of 0.5 ppm and 0.1 ppm BAP GA3 Keyword : Cassava Brown Streak Disease (CBSD), CASSAVA (Manihotesculentum), RT PCR

Abstract

Tissue culture have been used for plant propagation generally, and the medium has been important role in its growth. Vegetative propagation on Phalaenopsis sp orchids can be through the protocorm like bodies (PLB). Medium of affect on propagation of PLB was carried out on medium type, kind of basal medium and concentrations ratio of naphtaleneacetic acid (NAA) and benzylamino purine (BAP). The experiment used Completely Randomized Factorial Design with 3 replications and continued with the Duncan Multiple Range Test (DMRT) if there were significant differences. The results showed that the best callus formed in a combination of solid medium type and Murashige & Skoog (MS) basal medium was 100%. The most number of PLB produced from a combination of liquid medium types and a concentration ratio of NAA 1 mgL-1 and BAP 5 mgL-1, the most number of plantlet produced from a combination of MS basal medium and the concentrations ratio of NAA 0.1 mgL-1 and BAP 0.1 mgL-1, the number of PLB germination and PLB with leaves were influenced by each single factor.
