Abstract

Response of various soybean genotipes against cowpea mild mottle virus (CPMMV) infection. The green house experiment was conducted to investigate the effect of CPMMV infection on growth and yield of various soybean varieties. Treatments were arranged in completely randomized block design in split plot experiment. Mainplots were virus-inoculated and uninoculated plants; subplots were eight soybean varieties: Wilis, Orba, MLG 2521, Taichung, B 3570, Dieng, Tidar, and Pangrango. The results of this experiment showed that CPMMV infection decreased vegetative growth and yield of soybean plant. The decrease of dry weigth of soybean plant proved that CPMMV infection inhibited the vegetative growth. Taichung variety susceptible to CPMMV was indicated by significant reduction of the growth and yield. B3570 line tolerance to CPMMV infection was proved by lower reduction of the yield.

Abstract

Segregation pattern of the Soybean Stunt Virus resistant character and genetic diversity of F2:3 families derived from crosses between Orba and B3570. Soybean stunt disease caused by SSV (Soybean Stunt Virus) is the most destructive soybean disease in Indonesia. This research was conducted from October 2005 to June 2006 at experiment station of Lampung University. The aims of this research were to evaluate the segregation of resistant characters and total genetic diversity of eight populations of F2:3 families. Experiment was arranged in a randomized complete block design with three replications. The resistance was evaluated based on the score of disease severity. The results showed that the resistant characters segregate 1:2:1 to susceptible, moderately resistant, and resistant, respectively based on the segregation pattern. The resistant character was controlled by single gene and the action of the gene is noncompletely dominant gene. Eight populations of F2:3 families have high diversities on the yield and yield components.

Abstract

Cloning and sequencing of coat protein gene and 3’UTR (untranslated region) of peanut stripe virus. The cDNA of 3' terminal of peanut stripe virus genomic RNA was cloned and sequenced. The cDNA was ligated with plasmid vector pGEM-T Easy and transformed to competent cells of Escherichia coli. The 3' terminal of PstV genomic RNA contained 1195 nucleotides (nts). The region included the nucleotide sequences of NIb (nuclear inclusion body) (129 nts), CP gene (coat protein gene) (861 nts), and 3'UTR (untranslated region) (205 nts). The nucleotide sequence of a CP gene contained one long uninterrupted open reading frame (ORF) without a start codon, which ended a UAG stop codon. The 287 amino acid residues of PStV coat protein were predicted from the CP gene. The amino acid was analyzed for the presence of consensus polyprotein cleavage site for maturation of potyvirus polyprotein. A putative cleavage site was found at position 43 (Q/S) following the Valine (V) residue at -4 position. This isolate of PstV can be expected to be aphid transmissible because the coat protein contained a DAG triplet at position 53-55.
