“…These phytoplasmas have been diagnosed through PCR with primers specific for the 16S rRNA gene and cause abnormal growth, severe cladode proliferation and lack of flowers, fruits and spine production, lacking the presence of viral particles under the electronic microscope [24] . Some typical symptoms have been previously described for Indian fig phytoplasmas, for example formation of multiple buds, called "witches broom" [8] following the method by Ahrens and Seemuller [1] and using primers R16m F2/R16m R1 and R16 F2/R2 [17] .…”

The symptoms found, deforming, buds proliferation, thickening and heart-shaping in cladodes, with arrested plant growth and deep yellowing of cladodes, were all attributed to the presence of a phytoplasma given the amplification of a 1200 pb fragment of the 16S rRNA gene using primers R16 F2/R2 and R16F2n/R2 and 80% of phytoplasma transmission efficiency of successful grafts. Conclusion: Although the symptoms observed did not completely match those described for this organism in the region, a 1200 pb fragment was amplified and PCR products restriction analysis leading us to assume that the phytoplasma corresponds to subgroup 16Srll, previously reported for other crops in others world regions.

“…P. australiense" was detected in potato in New Zealand (Liefting et al 2009). In Australia, this phytoplasma species has been associated with Australian grapevine yellows, Papaya dieback (Liefting et al 1998), as well as diseases in a range of other hosts including strawberry, pumpkin and bean (Streten and Gibb 2006).…”

“…In Australia, it is a vector (or a reputed vector) of several diseases caused by phytoplasmas and mycoplasma-like organisms that inhabit the phloem sieve tubes of plants (Bowyer et al 1969;Bowyer & Atherton 1971), and which impact on foliage and seed production in various ways. The diseases include tomato big bud, purple-top wilt of potato, yellow dwarf of tobacco, witches' broom of lucerne, Australian lucerne yellows and little leaf of stylo (Stylosanthes scabra) (Helson 1951;Hutton & Grylls 1956;Bowyer 1974;Davis et al 1997;de la Rue et al 2001;Pilkington et al 2004;Streten & Gibb 2006).…”

Intraspecific variation within Orosius argentatus Evans (Hemiptera: Cicadellidae): colour polymorphisms, morphometric analyses and host associations

Orosius argentatus shows extreme colour variation and is reputedly highly polyphagous, circumstances that both warrant confirmation that the taxon comprises only one species. Because the species transmits phytoplasma pathogens between plants, information on species status is relevant to epidemiological studies. Replicated field samples, taken in Mareeba, North Queensland, over 2 years indicated that O. argentatus is the most abundant leaf-hopper in stylo (Stylosanthes scabra) and is relatively hostspecific on cultivated stylo, at least locally. A priori groupings of colour types were established for morphometric analyses of head, prothorax, tibia, wing and genitalia characters. No consistent morphological differences were detected across the colour types, and results from colour heritability trials, although limited, revealed that females could produce progeny that belong to multiple colour types. The results from this study suggest individuals that key out to the species O. argentatus, despite being polymorphic in colour, cannot be clearly separated on any morphological basis and therefore are likely to belong to a single, interbreeding population. The colour variation in adults is therefore a polymorphism.
