“…The VIS plants showed a significant reduction in Chlb, total Chl and relative Chl content compared with control plants. This is consistent with the report that the Chlb content decreased in virusinfected apple leaves (Bertamini et al, 2002) and suggests that Chlb was more sensitive than Chla to similar stress conditions, as reported by Palanisamy et al (2009) and Zhang et al (2020). Previous research has suggested that a decrease in the Chl content of infected leaves might reduce P N (Funayama et al, 1997;Sayed, 2003).…”

Strawberry mottle virus (SMoV) and strawberry vein banding virus (SVBV) cause diseases on strawberry plants, but the effect of coinfection of SMoV and SVBV on the growth, development, and defense system of strawberry (Fragaria × ananassa Duchesne) remains unknown. We investigated the effect of SMoV and SVBV coinfection on strawberry cultivar 'Benihope'. The results showed that stem diameter, leaf size, leaf number, relative chlorophyll content, total chlorophyll content, photosynthetic parameters, and stomatal aperture of SMoV and SVBV co-infected strawberry (VIS) plants were in a weaker level than uninfected control plants, indicating that viruses inhibited the growth and photosynthesis of strawberry plants. Furthermore, the initiation of flowering and fruiting stages of VIS plants were delayed by about three weeks compared with the controls, and the fruiting period was shortened, demonstrating that the reproduction of VIS plants was inhibited. Fruit quality was damaged in VIS plants due to a significant increase in fruit firmness and titratable acidity and decrease in total soluble solid content than control fruits. More dead cells and H 2 O 2 accumulated along the veins of VIS leaves, and the content of abscisic acid and catalase activity significantly increased, whereas anthocyanin content was lower than that of control plants. The results demonstrate that SVBV and SMoV coinfection inhibits the growth and development of 'Benihope' strawberry plants, and the plants respond to viruses by regulating stomatal aperture, the accumulation of ABA and antioxidants.To our knowledge, this study contributes information to understand how both viruses impair the strawberry growth and development for the first time.

“…1). The losses could be essentially attributed to distortion of the leaf structure; hence compromising the functioning of pigment synthesis pathways that essentialy involve light capture by the leaf (Palanisamy et al, 2009). What follows is a photo-inhibitory process that obviously affects the amount of light that the plant can intercept and utilise in photosynthesis.…”

“…The decline observed in carotenoid contents robs the plants of its protective mechanisms against damaging radiation, and may be due to leaf chlorosis, leaf blister formation, size reduction and deformation (Palanisamy et al, 2009;Srivastava et al, 2010). Such morphological, changes further exacerbate CBSD effects on cassava leaf physiology and may lead to photodamage of the chlorophylls systems (Vass, 2011).…”

“…The development of most plants infected with pathogens showing yellow vein symptoms would be influenced and sometimes the plants would die finally. There have been many studies reported that the plants infected with yellow vein related pathogens would grow accompanied with a series of changes like the damage to photosystem in leaves ( Palanisamy, Michael & Krishnaswamy, 2009 ), necrotic lesions and veinal necrosis ( Ravelo et al, 2007 ). However, if the infected plants can still grow, they could become new sources like ornamental plants ( Valverde, Sabanadzovic & Hammond, 2012 ).…”

Color variation in plant tissues is a common phenomenon accompanied with a series of biological changes. In this study, a special-phenotype Aquilaria sinensis (GS) with color variation of leaf was firstly reported, and DNA barcode sequences showed GS samples could not be discriminated clearly with the normal A. sinensis sample (NS), which suggested that the variety was not the cause of the GS formation. To reveal the characteristics of GS compared to NS, the anatomical and transcriptome sequencing studies were carried out. In microscopic observation, the leaves of golden-vein-leaf sample (LGS) and normal-vein-leaf sample (LNS) showed significant differences including the area of the included phloem in midrib and the thickness parameters of palisade and spongy tissues; the stems of golden-vein-leaf sample (SGS) and normal-vein-leaf sample (SNS) were also different in many aspects such as the area of vessels and included phloem. In addition, the structure of chloroplast was more complete in the midrib of LNS than that of LGS, and some particles suspected as virus were found through transmission electron microscope as well. Genes upregulated in LGS in contrast with LNS were mainly enriched in photosynthesis. As for stems, most of the genes upregulated in SGS compared to SNS were involved in translation and metabolism processes. The pathways about photosynthesis and chlorophyll metabolism as well as some important transcription factors may explain the molecular mechanism of the unique phenotypes of leaves and the genes related to suberin biosynthesis may result in the difference of stems. In addition, the genes about defense response especially biotic stress associated with numerous pathogenesis-related (PR) genes upregulated in LGS compared to LNS indicated that the pathogen may be the internal factor. Taken together, our results reveal the macro- and micro-phenotype variations as well as gene expression profiles between GS and NS, which could provide valuable clues for elucidating the mechanism of the color variation of Aquilaria.
