Aspects Regarding the Action of CCC in Hollyhock Plants

CCC [(2-chloroethyl) tnmethyl ammonium chloride] retarded shootelongation and increased leaf thickness and size (or volume)of leaf mesophyll cells in hollyhock plants. Photosyntheticactivities were stimulated by CCC, whereas post-illuminationCO₂ outburst-1 [PIB-1], PIB-2 and dark respiration were depressedby CCC. Chlorophyll and protein content of leaves treated withCCC also increased as compared with those of control leaves.CCC enabled the plant to bear flowers at the nodes from lowerto upper positions of the hollyhock shoots without flower (bud)abortion. Key words: Photosynthesis, CCC, mesophyll cell     

Isolation and characterization of new microsatellite markers in mango (Mangifera indica)

Six microsatellite loci that were isolated from a microsatellite‐enriched genomic library of mango (Mangifera indica) along with their specific primer sets were each characterized by using 36 cultivars collected mainly in Thailand. The observed and expected heterozygosities ranged from 0 to 0.83 and from 0.29 to 0.73, respectively. The number of putative alleles are two to six. Three of the six alleles have frequencies of over 75%. The high frequency may be attributed to the bias in the origin of cultivars. Among 36 mango cultivars tested, 29 cultivars showed a unique pattern by six primer sets, whereas seven cultivars cannot be identified because of genotype similarities. This suggests the potentials for identification of mango cultivars by microsatellite markers.
