Summary: We evaluated the suppressive effect of prohydrojasmon (PDJ) on Frankliniella occidentalis and tomato spotted wilt virus (TSWV) in chrysanthemums under semi-commercial conditions. The overhead sprinkling of plants with PDJ significantly reduced feeding damage on leaves and the reproduction of larval offspring. PDJ also suppressed the occurrence of TSWV transmitted by viruliferous adult thrips, suggesting its potential in controlling orthotospovirus diseases.

Summary: The Tomato spotted wilt virus (TSWV) is highly destructive to tomato cultivation globally, with only the natural resistance gene Sw-5 demonstrating high resistance. Over time, however, resistance induced by Sw-5 weakens due to the global spread of TSWV, necessitating the exploration of other resistance genes and novel resources for breeding TSWV-resistant tomato varieties.

Summary: This study reveals that a plant virus induces the production of a specific volatile in its host plant, which is recognized by an olfactory protein in its insect vector. This manipulation of insect behavior by the virus enhances viral spread and transmission. The findings shed light on how plant viruses control insect vector behavior through chemical signals.

Summary: Tomato spotted wilt virus (TSWV) is transmitted by specific thrips, including the western flower thrips, and induces immune responses in the insects. We found that TSWV infection triggers the release of a damage-associated molecular pattern called DSP1, leading to the activation of immune responses in the thrips.

Summary: Detecting viruses in the early stages of infection is challenging due to their low abundance, making it difficult to use sensitive laboratory techniques. To overcome this, researchers have developed a portable and affordable system that can detect tomato spotted wilt orthotospovirus in real time using a technique called Recombinase Polymerase Amplification. This technique allows for detection directly from crude plant extracts without the need for nucleic acid extraction and can be visually identified by the formation of DNA-flocculus complexes. This system provides a practical solution for in-field virus detection and can be used by scientists and extension managers without the need for specialized laboratory facilities.

Summary: The transmission of insect-borne viruses involves intricate interactions between viruses, host plants, and vectors. Chemical compounds play a vital role in these interactions. This study demonstrates that a plant virus infection can alter the chemical composition of its host plant, making it more attractive to its vector and enhancing the vector's biological performance. These findings provide insights into the physiological mechanisms behind the virus's benefits to its vector.

Summary: In this study, a tomato inbred line, YNAU335, showed immunity to tomato spotted wilt virus (TSWV) at first but later lost its immunity. The researchers used various techniques to analyze the pathological features and genetic polymorphism of the TSWV infecting the tomato fruit. They discovered a mutated protein that likely caused the loss of immunity in YNAU335.

Summary: A total of 35 piperazine derivatives were synthesized and assessed for their anti-tomato spotted wilt virus (TSWV) activity. Compounds 34 and 35 displayed significant potency against TSWV with EC50 values of 62.4 and 59.9 μg/mL, respectively, superior to the control agents ningnanmycin and ribavirin. Mechanistic studies revealed that compounds 34 and 35 inhibited TSWV infection by binding to the N protein, preventing assembly of the viral core structure ribonucleoprotein (RNP). Amino acid residue 94 on the N protein was identified as the key site for interaction between the compounds and the TSWV N target. This study highlights the potential of piperazine derivatives containing alpha-ketoamide moieties as antiviral agents.

Summary: Investigating population genetics of Thrips-transmitted tomato spotted wilt orthotospovirus (TSWV) isolates collected from peanut cultivars with varying levels of TSWV resistance revealed no evidence of resistance exerting selection pressure on TSWV. Despite differences in susceptibility to thrips among evaluated cultivars, no significant impact of resistance on TSWV was found.

Summary: Detection of morphological stress symptoms through 3D examination of plants is a cost-efficient way to prevent yield losses and ensure product quality in agriculture and horticulture. The relationship between morphological and physiological plant responses to salinity stress needs further investigation. The study showed that morphological changes in leaf dimensions can serve as indicators for physiological responses in leaves under salinity stress.

Summary: Photosynthetic light response curve parameters are important for understanding the variation in photosynthetic traits, leaf acclimation status, carbon uptake, and plant productivity among different species. In this study, we analyzed the net photosynthetic light response curves and leaf traits of four amaranth species and found that maximum gross photosynthetic rate and leaf traits were correlated with plant productivity. We also observed that A. hybridus and A. cruentus had higher photosynthetic rates and light use efficiency compared to A. dubius and A. hypochondriacus. These findings highlight the importance of leaf photosynthetic characteristics and other leaf traits in determining plant productivity in amaranths.
