Joint Effects of Balancing Selection and Population Bottlenecks on the Evolution of a Regulatory Region of Human Antiviral APOBEC3.. Human antiviral APOBEC3s are crucial components of the innate immune response, playing a key role in inhibiting viral replication and proliferation by inducing mutations in viral genomes. In this study, in a regulatory region of ∼16 kb in the APOBEC3 gene cluster on human chromosome 22, we identified three distinct haplogroups that are maintained at high frequencies in both African and non-African populations. Despite the long persistence of these haplogroups, one of which is shared by archaic hominins, the nucleotide diversity within each haplogroup was surpr…

POPULATION TRENDS OF RICE GREEN LEAFHOPPERS IN CAUVERY DELTA ZONE OF TAMIL NADU. Peak occurrence of green leafhoppers (GLH) was observed during September and October months of the three years 1991 93. The species composition in light-trap and field collections revealed that Nephotettix virescens dominated over N. nigropictus. The seasonal incidence of GLH in the three defined seasons of Cauvery Delta Zone revealed that early planting of the crop in Kuruval season i... July 25 recorded low incidence of GLH than the late planted crop. The early as well as late planting of samba and thaladi season was susceptible to GLH. Among the weather factors. relative humidity and minimum temperature infl…

Enhancing germination and seedling quality of Turkey berry (Solanum torvum) through seed dormancy-breaking methods. The Turkey berry plant (Solanum torvum Sw), used as rootstock for vegetable grafting and a key medicinal species in Indian Systems of Medicine (ISM), and homeopathy from the Solanaceae family, faces challenges in commercial cultivation due to seed dormancy, which inhibits germination. To enhance the germination and seedling quality characteristics of Turkey berries, an experiment was therefore carried out in the Department of Vegetable Sciences at the Tamil Nadu Agricultural University, Coimbatore, in the years 2022–2023. In this study, effectiveness of seed dormancy-breaking…

ADT 41 (JJ 92): A DWARF BASMATI RICE FOR TAMIL NADU. Basmati rice is praised for aroma and super fine quality. Traditional Basmati rice varieties are tall, lodging, photosensitive and with low yield potential. The improved Basmati varieties viz., Pusa Basmati 1 and Kasturi are not suitable for cultivation in Tamil Nadu because of their poor adaptation and yield. The research oriented on this line has resulted in the identification of a dwarf Basmati (AD 90190) with high yield potential retaining Basmati qualities and this selection was identified from the irradiated dwarf mutant of Basmati 370. The average grain yield is 4758 kg/ha in a crop duration of 110 days. This culture has been relea…
