Urdbean leaf crinkle disease (ULCD) affects mainly the urdbean or blackgram (Vigna mungo (L.) Hepper) causing distinct symptoms that often result in serious yield losses. It has been known to occur for more than five decades and is considered to be of viral etiology. The identity of the causal agent, often referred to as the urdbean leaf crinkle virus, is not unequivocally proved. There are few attempts to characterize the causal agent of ULCD; however, there is no unanimity in the results. Recent attempts to characterize the causal agent of ULCD using next-generation sequencing of the virome of ULCD-affected urdbean plants indicated the involvement of cowpea mild mottle virus; however, without conforming through Koch’s postulates, the etiology of ULCD remains inconclusive. Claims of different insect vectors involved in the transmission of ULCD make this disease even more mysterious. The information available so far indicates that either two different viruses are causing ULCD or a mixture of viruses is involved. The identity of the virus/es causing ULCD still remains to be unambiguously ascertained. In this review, we attempt to analyze information on the various aspects of ULCD.

Urdbean Leaf Crinkle Virus: A Mystery Waiting to Be Solved

Pollution and climate change negatively affect plant health. The growing demand for global food production in the agricultural sector is a decisive driving force for the development of new disease control methods that are effective against known pathogens. Plants possess specialized structures, chemicals, and complex defense mechanisms against pathogens. Understanding these defense mechanisms and pathways is critical to developing innovative approaches to protecting crops from disease. Plant stress can be reduced by applying salicylic acid, which is involved in plant signaling. Salicylic acid induces pathogenetic gene expression and the synthesis of protective compounds involved in local and systemic acquired resistance. For this reason, salicylic acid can be used against pathogens, heavy metal stress, and salt stress. The applied salicylic acid enhances photosynthesis, growth, and various morphological, physiological, and biochemical mechanisms in stressed plants. In this article, we look at the use of exogenous salicylic acid for the relief of bacterial, fungal, and viral diseases.
