When opportunity arose he would offer to make a more finished sketch of her, he was sure she would like that; her face was interesting, the profile was lovely, and there was something curiously fascinating about the chlorotic
There are several examples of the successful spread of begomoviruses over long-distances in recent times, such us the global emergence of TYLCV causing damage in tomato, the rapid spread of cucurbit-infecting begomoviruses (Squash leaf curl virus, SLCuV; Watermelon chlorotic
stunt virus, WmCSV; Tomato leaf curl New Delhi virus, ToLCNDV) in the Middle East and/or Mediterranean countries, or the spread of the cassava mosaic diseaseassociated begomoviruses in continental and insular Africa.
Try using a fertilizer containing iron on all plants, not just the chlorotic
Despite the importance of the crop especially to small scale farmers, its production is mainly threatened by viral diseases such as Sweet potato feathery mottle virus (SPFMV), Sweet potato mild mottle virus (SPMMV), Sweet potato virus G (SPVG), Sweet potato chlorotic
stunt virus (SPCSV), Sweet potato latent virus (SPLV), Sweet potato caulimo-like virus (SPCV), Sweet potato ring spot virus (SPRSV) and Cucumber mosaic virus (CMV).
rubrocinctus on the leaves causes the development of chlorotic
spots and premature leaf drop, while feeding on the pods causes brown patches that coalesce during heavy infestations, forming a dark brown and corky layer of dead cells.
MLND is a viral maize disease caused by co-infection with maize chlorotic
mottle virus (MCMV) and other viruses like the sugarcane mosaic virus.
phaeotricha seedlings were: chlorotic
leaves (Figure 1A), cotyledon with evidence of damages to the terminal bud (Figure 1B), absence of apical bud in the epicotyl (Figure 1C), absent or poorly developed primary root (Figure 1D).
The plants subjected to P deficiency presented visual symptoms such as narrow leaf insertion angle, opaque dark green color, low vegetative development, and leaves with homogeneous distribution of chlorotic
points in the internerval regions followed by necrosis, and upward curved edges (Figure 1b).
AltMV is known to manifest a wide range of symptoms including chlorotic
spotting of various size, chlorosis, chlorotic
local lesions, leaf distortion and curling, mosaic, mottle, necrotic spotting of various size, necrotic ringspots, rugosity, veinal necrosis, and interveinal yellowing (Table 2) [1, 2,12,15,17].
Therefore, to further explore the leaf responses to NPK deficiencies, we segmented the chlorotic
part to reveal the development of leaf chlorosis.
Disease was recorded using 0-4 infection scale : (0) no uredia or other macroscopic sign of infection, (;) no uredia, but hypersensitive necrotic or chlorotic
flecks present, (1) small uredia surrounded by necrosis, (2) small to medium uredia often surrounded by chlorosis; green islands may be surrounded by chlorotic
or necrotic border, (x) random distribution of variable-sized uredia on single leaf, (3) medium sized uredia that may be associated with chlorosis, and (4) large uredia without chlorosis.
