legumes. 3. Variation in sensitivity to bacteriophages. JOURNAL OF
PHYTOPATHOLOGY, v.100(2):97-110. [En] [En De Absti (A:PS)
When 51 bacteriophages (established using xanthomonads as the host
bacterium) were tested against 117 bacterial cultures representing Xanthomonas
(101), Pseudomonas (12), Erwinia (2), Bacillus (1) and Rhizobium (1), all were
found specific to the genus Xanthomonas and none was species specific. Further,
none attacked all the nomen species tested. An individual phage strain obtained
by employing a particular isolate of a bacterial species not only reacted with
other bacterial species, but also failed to react with all the isolates of the
same species. No definite trend, either in phage sensitivity in the bacterial
isolates or attackability of the phages, was observed, that can be used for the
identification of the nomen species of Xanthomonas of pulses or other crops.
Colony variants of different pulse pathogens behaved similarly to the phages
isolated from their natural hosts, but similarly or differently to phages from
other r .,3ecrops, leguminous and non-leguminous hosts. White mutants of
mungbean, cowpea and castor xanthomonads behaved like their yellow forms to the
phages isolated from their natural hosts, but could be distinguished from their
parent yellow strains by some phage isolates frcm other hosts. P. azadirachtae
and P. mangiferaeindicae were lysed by 11 and 16 Xanthomonas phages,
respectively, but eight other true Pseudomonas cultures were not attacked by
any of the 51 Xanthomonas phages. [AS]

orna-entals and vegetables in Madras State. INDIAN PHYTOPATHOLOGY,
v.16(I):74-85. [En] LEn Abst] (REP.MB-0993)
Six bacterial diseases of common ornamental plants and seven of vegetables
in Madras State were studied in detail. Of these six are identified as caused
by new species of bacteria, viz., Xanthomonas cosmosicola sp. nov., on Cosmos
sylphureus Cay., X. tagetis sp. nov., on Tagetes erecta L., X. balsamicorum sp.
nov., on Impatiens balsamina L., Pseudomonas hibiscicola, sp. nov., on Hibiscus
rosa-sinensis L., Ps. cyamopsicola sp. nov., Cyamopsis psoralioides DC and Ps.
madrasensis sp. nov.,.on Amaranthus viridis L. The other seven are identified
as Ps. syringae van Hall on Chrysanthemum indicum L., X. nigromaculans
(Takimoto) Dowson Zinnia elegans L., Ps. tomato Okabe on Lycopersicon
esculentum Mill., and Capsicum annuum L., X. vignicola Burk. on Vigna cat-jang
Walp. and X. phaseoli (E.F. Sm.) Dowson on Vigna mungo and Dolichos lablab L.
Of these records on Chrysanthemum indicum, Zinnia elegans and Lycopersicon
esculentum are new for India, on Vigna mungo and Capsicum annuum new for the
hosts, and on Dolichos lablab and Vigna catjang new for Madras State. (AS]
