An Overview of Chili Leaf Curl Disease: Molecular Mechanisms, Impact, Challenges, and Disease Management Strategies in Indian Subcontinent. Front Microbiol 2022; 13:899512. [PMID: 35847087 PMCID: PMC9277185 DOI: 10.3389/fmicb.2022.899512] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 05/30/2022] [Indexed: 11/13/2022] Open
Abstract
Leaf curl disease in a chili plant is caused mainly by Chili leaf curl virus (ChiLCV) (Family: Geminiviridae, Genus: Begomovirus). ChiLCV shows a widespread occurrence in most of the chili (Capsicum spp.) growing regions. ChiLCV has a limited host range and infects tomatoes (Solanum lycopersicum), potatoes (S. tuberosum), and amaranth (Amaranthus tricolor). The virus genome is a monopartite circular single-stranded DNA molecule of 2.7 kb and associated with α and β-satellites of 1.3 and 1.4 kb, respectively. The virus genome is encapsulated in distinct twinned icosahedral particles of around 18-30 nm in size and transmitted by Bemisia tabaci (Family: Aleyrodidae, Order: Hemiptera). Recently, bipartite begomovirus has been found to be associated with leaf curl disease. The leaf curl disease has a widespread distribution in the major equatorial regions viz., Australia, Asia, Africa, Europe, and America. Besides the PCR, qPCR, and LAMP-based detection systems, recently, localized surface-plasmon-resonance (LPSR) based optical platform is used for ChiLCV detection in a 20-40 μl of sample volume using aluminum nanoparticles. Management of ChiLCV is more challenging due to the vector-borne nature of the virus, therefore integrated disease management strategies need to be followed to contain the spread and heavy crop loss. CRISPR/Cas-mediated virus resistance has gained importance in disease management of DNA and RNA viruses due to certain advantages over the conventional approaches. Therefore, CRISPR/Cas system-mediated resistance needs to be explored in chili against ChiLCV.

Abstract
Begomoviruses are a major class of Geminiviruses that affects most dicotyledonous plants and causes heavy economic losses to farmers. Early detection of begomovirus is essential to control the spread of the disease and prevent loss. Many available detection methods like ELISA, immunosorbent electron microscopy, PCR or qPCR require expertise in handling sophisticated instruments, complex data interpretation and costlier chemicals, enzymes or antibodies. Hence there is a need for a simpler detection method, here we report the development of a visual detection method based on functionalized gold nanoparticles (AuNP assay). The assay was able to detect up to 500 ag/µl of begomoviral DNA (pTZCCPp3, a clone carrying partial coat protein gene) suspended in MilliQ water. Screening of chilli plants for begomoviral infection by PCR (Deng primers) and AuNP assay showed that AuNP assay (77.7%) was better than PCR (49.4%). The AuNP assay with clccpi1 probe was able to detect begomoviral infection in chilli, tomato, common bean, green gram and black gram plants which proved the utility and versatility of the AuNP assay. The specificity of the assay was demonstrated by testing with total DNA from different plants that are not affected by begomoviruses.

Abstract
Three full-length monopartite begomovirus sequences were obtained from two field-collected pepper plants exhibiting severe leaf yellowing disease symptoms in Yunnan province of China. The three full-length viral sequences contain 2,748 nucleotides (nt) and share the highest nt sequence similarity (88.2% identity) with that of malvastrum yellow vein Yunnan virus (MYVYNV). The betasatellite molecules of the two viruses share the highest sequence similarity (99.3% identity) with that of malvastrum yellow vein Yunnan betasatellite (MYVYNB). Based on the current species demarcation criteria for the genus Begomovirus, these three newly identified isolates can be considered members of a novel monopartite Begomovirus species, and we have named this virus "pepper yellow leaf curl virus" (PepYLCV). Phylogenetic analysis showed that PepYLCV clustered with pepper leaf curl Yunnan virus (PepLCYNV). Recombination analysis revealed that PepYLCV is likely to have originated through a recombination event between MYVYNV and tomato leaf curl Yunnan virus (TLCYnV).

Abstract
Management of geminiviruses is a worldwide challenge because of the widespread distribution of economically important diseases caused by these viruses. Regardless of the type of agriculture, management is most effective with an integrated pest management (IPM) approach that involves measures before, during, and after the growing season. This includes starting with resistant cultivars and virus- and vector-free transplants and propagative plants. For high value vegetables, protected culture (e.g., greenhouses and screenhouses) allows for effective management but is limited owing to high cost. Protection of young plants in open fields is provided by row covers, but other measures are typically required. Measures that are used for crops in open fields include roguing infected plants and insect vector management. Application of insecticide to manage vectors (whiteflies and leafhoppers) is the most widely used measure but can cause undesirable environmental and human health issues. For annual crops, these measures can be more effective when combined with host-free periods of two to three months. Finally, given the great diversity of the viruses, their insect vectors, and the crops affected, IPM approaches need to be based on the biology and ecology of the virus and vector and the crop production system. Here, we present the general measures that can be used in an IPM program for geminivirus diseases, specific case studies, and future challenges.

Abstract
Chilli leaf curl disease (ChiLCD) is a serious problem and a major limitation to chilli (Capsicum spp.) cultivation in India. Leaves of a chilli plant showing leaf curl symptoms were collected from the Gonda district in Uttar Pradesh, India, in April, 2013. Full-length genomes of a begomovirus and an associated betasatellite were amplified, cloned and sequenced. The size of the begomovirus genome and the betasatellite were 2760 bp and 1374 bp, respectively. The nucleotide sequence of the begomovirus genome shared maximum identity (89 %) with pepper leaf curl Bangladesh virus-India isolate Chhapra (PepLCBV, JN663853), below the threshold for species demarcation. Sequence analysis showed that the begomovirus is a potential recombinant between viruses related to PepLCBV and chilli leaf curl virus (ChiLCV). The name chilli leaf curl Gonda virus (ChiLCGV) is being proposed. The betasatellite associated with ChiLCGV was identified as tomato leaf curl Bangladesh betasatellite (ToLCBDB). Agroinoculation of the viral genome along with betasatellite induced severe leaf curl symptoms in Nicotiana benthamiana. ChiLCGV and ToLCBDB characterized in this study represent a new begomovirus-betasatellite complex infecting Capsicum.

Abstract
Tomato and pepper are widely grown in Oman for local consumption. A countrywide survey was conducted during 2010-2011 to collect samples and assess the diversity of begomoviruses associated with leaf curl disease of tomato and pepper. A virus previously only identified on the Indian subcontinent, chili leaf curl virus (ChLCV), was found associated with tomato and pepper diseases in all vegetable grown areas of Oman. Some of the infected plant samples were also found to contain a betasatellite. A total of 19 potentially full-length begomovirus and eight betasatellite clones were sequenced. The begomovirus clones showed >96% nucleotide sequence identity, showing them to represent a single species. Comparisons to sequences available in the databases showed the highest levels of nucleotide sequence identity (88.0-91.1%) to isolates of the "Pakistan" strain of ChLCV (ChLCV-PK), indicating the virus from Oman to be a distinct strain, for which the name Oman strain (ChLCV-OM) is proposed. An analysis for recombination showed ChLCV-OM likely to have originated by recombination between ChLCV-PK (the major parent), pepper leaf curl Lahore virus and a third strain of ChLCV. The betasatellite sequences obtained were shown to have high levels of identity to isolates of tomato leaf curl betasatellite (ToLCB) previous shown to be present in Oman. For the disease in tomato Koch's postulates were satisfied by Agrobacterium-mediated inoculation of virus and betasatellites clones. This showed the symptoms induced by the virus in the presence of the betasatellite to be enhanced, although viral DNA levels were not affected. ChLCV-OM is the fourth begomovirus identified in tomato in Oman and the first in Capsicum. The significance of these findings is discussed.

Abstract
Leaf curl disease of chilli (LCDC) is a major constraint in production of chilli in the Indian subcontinent. The objective of this study was to identify the begomovirus species occurring in chilli in Sri Lanka, where the LCDC was initially recorded in 1938. The virus samples were collected from the North Central Province, the major chilli growing region in Sri Lanka with a history of epidemic prevalence of LCDC. The virus could be readily transmitted by Bemisia tabaci to chilli, tomato and tobacco, where vein clearing followed by leaf curl developed. The genome analysis of two isolates obtained from two distantly located fields showing 100 % LCDC, revealed that the DNA-A genome (2754 nucleotides) shared 89.5 % sequence identity with each other and 68.80-84.40 % sequence identity with the other begomoviruses occurring in the Indian subcontinent. The closest identity (84.40 %) of the virus isolates was with Tomato leaf curl Sri Lanka virus (ToLCLKV). The results support that a new begomovirus species is affecting chilli in Sri Lanka and the name Chilli leaf curl Sri Lanka virus (ChiLCSLV) is proposed. Recombination analysis indicated that ChiLCSLV was a recombinant virus potentially originated from the begomoviruses prevailing in southern India and Sri Lanka. The genome of betasatellite associated with the two isolates consisted of 1366 and 1371 nucleotides and shared 95.2 % sequence identity with each other and 41.50-73.70 % sequence identity with the other betasatellite species. The results suggest that a new begomovirus betasatellite, Chilli leaf curl Sri Lanka betasatellite is associated with LCDC in Sri Lanka. This study demonstrates a new species of begomovirus and betasatellite complex is occurring in chilli in Sri Lanka and further shows that diverse begomovirus species are affecting chilli production in the Indian subcontinent.

Abstract
BACKGROUND Begomoviruses are whitefly-transmitted geminiviruses with genomes that consist of either two components (known as DNA A and DNA B) or a single component (homologous to the DNA A component of bipartite begomoviruses). Monopartite begomoviruses are often associated with a symptom-modulating DNA satellite (collectively known as betasatellites). Both bipartite and monopartite begomoviruses with associated satellites have previously been identified in chillies showing leaf curl symptoms in Pakistan. RESULTS A chilli plant (Capsicum annum) with chilli leaf curl disease symptoms was found to contain a begomovirus, a betasatellite and the DNA B component of Tomato leaf curl New Delhi virus (ToLCNDV). The begomovirus consisted of 2747 nucleotides and had the highest sequence identity (99%) with Pepper leaf curl Lahore virus (PepLCLV-[PK: Lah:04], acc. no. AM404179). Agrobacterium-mediated inoculation of the clone to Nicotiana benthamiana, induced very mild symptoms and low levels of viral DNA, detected in systemically infected leaves by PCR. No symptoms were induced in Nicotiana tabacum or chillies either in the presence or absence of a betasatellite. However, inoculation of PepLCLV with the DNA B component of ToLCNDV induced leaf curl symptoms in N. benthamiana, N. tabacum and chillies and viral DNA accumulated to higher levels in comparison to plants infected with just PepLCLV. CONCLUSIONS Based on our previous efforts aimed at understanding of diversity of begomoviruses associated with chillies, we propose that PepLCLV was recently mobilized into chillies upon its interaction with DNA B of ToLCNDV. Interestingly, the putative rep-binding iterons found on PepLCLV (GGGGAC) differ at two base positions from those of ToLCNDV (GGTGTC). This is the first experimental demonstration of the infectivity for a bipartite begomovirus causing chilli leaf curl disease in chillies from Pakistan and suggests that component capture is contributing to the emerging complexity of begomovirus diseases in the region.
