| 1 | Back to Basics:Are Begomoviruses Whitefly Pathogens?显示文摘Begomoviruses and whiteflies have interacted for geological times.An assumed long-lasting virus-vector intimate relationship of this magnitude implies that the partners have developed co-evolutionary mechanisms that insure on one hand the survival and the efficient transmission of the virus,and on the other hand the safeguard of the insect host from possible deleterious effects of the virus.Several studies have indicated that viruses belonging to the Tomato yellow leaf curl virus(TYLCVs)family from China,Israel and Italy are reminiscent of insect pathogens.TYLCVs like all begomoviruses are transmitted in a circulative manner by the whitefly Bemisia tabaci.The survival of the virus in the haemolymph of B.tabaci is ensured by a GroEL homologue produced by a whitefly secondary endosymbiont.Following acquisition and transfer to non-host plants,the virus may remain associated with the insect for its entire 4-5 wk-long adult life.During this period,the ability of the insects to inoculate plants steadily decreased,but did not disappear.The long-term presence of TYLCVs in B.tabaci was associated with a decrease in the insect longevity and fertility.Viral DNA was transmitted to progeny,but seldom infectivity.TYLCV transcripts were found associated with the insects,raising the possibility of replication and expression in the vector.TYLCVs may spread amidst whiteflies during copulation.Functional genomics tools such as microarrays,deep sequencing,quantitative PCR and gene silencing allow revisiting the proposition that TYLCVs have retained,or acquired,some characteristics of an insect pathogen. | Henryk Czosnek Murad Ghanim | 2012 | Journal of Integrative Agriculture2012，11，2： | 2 |
| 2 | Bemisia tabaci Biotype Dynamics and Resistance to Insecticides in Israel During the Years 2008-2010显示文摘The sweetpotato whitefly Bemisia tabaci(Hemiptera:Aleyrodidae)is an extremely polyphagous insect pest that causes significant crop losses in Israel and worldwide.B.tabaci is a species complex of which the B and Q biotypes are the most widespread and damaging worldwide.The change in biotype composition and resistance to insecticide in Israel was monitored during the years 2008-2010 to identify patterns in population dynamics that can be correlated with resistance outbreaks.The results show that B biotype populations dominate crops grown in open fields,while Q biotype populations gradually dominate crops grown in protected conditions such as greenhouses and nethouses,where resistance outbreaks usually develop after several insecticide applications.While in previous years,Q biotype populations were widely detected in many regions in Israel,significant domination of the B biotype across populations collected was observed during the year 2010,indicating the instability of the B.tabaci population from one year to another.Reasons for the changing dynamics and the shift in the relative abundance of B.tabaci biotype,and their resistance status,are discussed. | Svetlana Kontsedalov Fauzi Abu-Moch Galina Lebedev Henryk Czosnek A Rami Horowitz Murad Ghanim | 2012 | Journal of Integrative Agriculture2012，11，2： | 2 |

| 11 | Involvement of the Hexose Transporter Gene LeHT1 and of Sugars in Resistance of Tomato to Tomato Yellow Leaf Curl Virus显示文摘Dear Editor, Tomato yellow leaf curl virus (TYLCV) is a whitefly-transmitted geminivirus infecting tomato crops (Czosnek,2007).TYLCV-resistant (R) and susceptible (S) lines with the same genetic background have been bred using Solanum habrochaites as the resistance source.The gene(s) conferring resistance are unknown.Previously,we demonstrated that the hexose transpcrter gene LeHT1 is up-regulated upon infection in R plants and its silencing in R plants (RH) leads to the collapse of resistance (Eybishtz et al.,2010).To uncover the role of LeHT1 in resistance,we (1) analyzed the transcriptome reprogramming in leaves of S,R,and RH plants using a homedesigned microarray,before and 7 d after TYLCV inoculation (0,7 dpi),and (2) measured the concentration of sugars and their derivatives in S,R,and RH leaves at 1 and 7 dpi because LeHTI is transporting both glucose and fructose (McCurdy et al.,2010). | Dagan Sade Yariv Brotman Assa f Eybishtz Alvaro Cuadros-lnostroza Alisdair R.
