Sickle cell disease (SCD) is an autosomal recessive genetic blood disorder due to single nucleotide mutation (GAG > GTG) in the beta globin gene. In SCD patients, the red blood cells (RBCs) become sickle-shaped in the deoxygenated state. The sickle haemoglobin (HbS) has an amino acid substitution at the sixth position of the β-globin chain (p.Glu6Val). Among the wide spectrum of illnesses observed in sickle cell anaemia patients, who are homozygous for the mutant gene, the most important is chronic anaemia with an extremely low haemoglobin concentration and frequent episodes of sickle cell crisis. SCD was detected for the first time in India in 1952 in an Irula boy of Nilgiris, Tamil Nadu and then in eastern India.Full Text

Santalum album commonly known as Indian sandalwood, is extensively exploited due to its demand in the international market for essential oil. In the Indian subcontinent, the species is approaching commercial extinction due to overexploitation and sandal spike disease caused by phytoplasma. Molecular detection using PCR and RFLP is reported for disease diagnosis. In the present study, a single-step, stringent PCR-based assay was developed to detect the sandal spike phytoplasma. The titre estimation revealed that the marker maintained detection sensitivity up to 0.8 ng of template DNA. Subsequent to validation of the marker in a larger number of symptomatic individuals, this diagnostic assay can be routinely used to detect the pathogen. It will facilitate early detection and enable plantation managers to take adequate measures to control the spread of the disease.Keywords
