“…In addition to sunflower, TSV also infects many commercial crops including groundnut, cotton, soyabean, mungbean, chickpea. Recently, the rate of incidence of TSV in cotton was surveyed in various states of India by DAC-ELISA, where Telangana (India) had the highest incidence when compared to Tamil Nadu, Andhra Pradesh and Maharashtra [21]. Similarly, TSV was first identified in cluster bean by DAC-ELISA using TSV polyclonal antibodies [22].…”

“…The TSV disease was reported to be spread through mechanical means, infected seeds and through thrips species. Parthenium, a widely distributed and symptom less carrier of TSV, plays a major role in perpetuation and spread of the disease [91][92][93][94][95].…”

Cotton, a crop of choice, occupies the second premier position next to food crops in providing clothing. Though 53 species of Gossypium are available, only four species are cultivable and among the four, the major cultivable area falls under G. hirsutum. Though varieties with medium, superior medium, long and extra long staple cotton were released earlier, with the advent of machineries, ginning facilities, mills were literally requiring cotton fiber of any length. With the advent of Bt technology and the release of hybrids during 2002, cotton productivity had a momentum. However, considering the duration, cost involved in manual harvesting etc., farmers were looking for alternate option and High Density Planting System (HDPS) offered a promise in this direction. Farmers were looking for genotypes that could yield better under higher planting densities with fewer bolls per plant, synchronized maturity with uniform bursting. Efforts have been taken all over the World in this direction and India is not an exception. Handful of varieties fitting to this situation has been released from many of the Universities. This chapter essentially summarizes the genetic, agronomic, plant protection interventions and the futuristic requirements for achieving at least 700 kg of lint per hectare.

“…Tobacco streak virus (TSV), which belongs to the genus Ilarvirus (Family, Bromoviridae), has an extensive host range which infects several vegetable crops causing heavy crop loss (Jain et al, 2005(Jain et al, , 2008Sivaprasad et al, 2010). In addition to vegetable crops, it infects groundnut (Reddy et al, 2002), sunflower (Ramiah et al, 2001), soybean (Arun Kumar et al, 2008), blackgram (Ladhalakshmi et al, 2006) and cotton (Jagtap et al, 2012;Vinodkumar et al, 2017) in India. Besides, economic loss in terms of yield is under estimated from the field in several crops due to virus infection because it requires precise diagnostic techniques to determine the damage caused due to pathogen.…”

RNAs play a significant role in regulating gene expression and their principal areas have been exploited for the control of plant viruses by the discovery of RNA silencing mechanism. RNA silencing or RNA interference (RNAi) is an innovative mechanism that regulates and restricts the amount of transcripts either by suppressing transcription (TGS) or by the degradation of sequence-specific RNA. RNAi can be used effectively to study the role of genes in a variety of eukaryotic organisms by reverse genetics. The technology has been employed in several fields such as drug resistance, therapeutics, development of genetically modified animals for research and transgenic plants targeting plant viruses. In plants, small interfering RNAs (siRNA) are the characteristic of 21 to 22 bp long dsRNA, which has been recognized by the regulatory mechanism of RNAi and leads to the sequence-specific degradation of target mRNA. In addition to virus disease control, RNAi can also be used to control mycotoxins and plant diseases caused by other organisms. This review enhances our current knowledge of RNAi and its larger applications in agriculture, specifically in plant virus disease management.
