A new huanglongbing (HLB) "Candidatus Liberibacter" species is genetically characterized, and the bacterium is designated "Candidatus Liberibacter psyllaurous." This bacterium infects the psyllid Bactericera cockerelli and its solanaceous host plants potato and tomato, potentially resulting in "psyllid yellowing." Host plant-dependent HLB transmission and variation in psyllid infection frequenc...
Here, we report the complete genome sequence (2.92 Mb) of Methanosphaerula palustris E1-9C(T), a methanogen isolated from a minerotrophic fen. This is the first genome report of the Methanosphaerula genus, within the Methanoregulaceae family, in the Methanomicrobiales order. E1-9C(T) relatives are found in a wide range of ecological and geographical settings.
Selection of detectable numbers of Mi-virulent root-knot nematodes has necessitated a greater understanding of nematode responses to new sources of resistance. During the course of this research, we compared the reproduction of four geographically distinct Mi-virulent root-knot nematode isolates on three resistant accessions of Lycopersicon peruvianum. Each accession carried a different resista...
Phenylalanine Ammonia Lyase (PAL) gene which plays a key role in bio-synthesis of medicinally important compounds, Rutin/quercetin was sequence characterized for its efficient genomics application. These compounds possessing anti-diabetic and anti-cancer properties and are predominantly produced by Fagopyrum spp. In the present study, PAL gene was sequenced from three Fagopyrum spp. (F. tataric...
The fermentation product of herbs by lactic acid bacteria (FHL) was assayed for antifungal activities against Rosellinia necatrix, Helicobasidium mompa, Fusarium oxysporum, Pythium graminicola and Pyricularia oryzae. FHL completely inhibited the growth of R. necatrix, H. mompa, P. graminicola and P. oryzae, and reduced the growth of F. oxysporum by 35%. When the seeds of Medicago sativa L. (alf...
A library of "introgression lines" containing Solanum lycopersicoides chromosome segments in the genetic background of cultivated tomato (Lycopersicon esculentum) was used to study factors affecting homeologous recombination. Recombination rates were estimated in progeny of 43 heterozygous introgressions and whole-chromosome substitution lines, together representing 11 of the 12 tomato chromoso...
Root-knot nematode resistance of F progeny of an intraspecific hybrid (Lycopersicon peruvianum var. glandulosum Acc. No. 126443 x L. peruvianum Acc. No. 270435), L. esculentum cv. Piersol (possessing resistance gene Mi), and L. esculentum cv. St. Pierre (susceptible) was compared. Resistance to 1) isolates of two Meloidogyne incognita populations artificially selected for parasitism on tomato p...
کم آبی یکی از فاکتورهای مهم محیطی است که رشد و نمو گیاهان را تحت تأثیر قرار داده و تولید گیاهان را محدود می کند. نیتریک اکسید یک رادیکال گازی نسبتاٌ پایدار است که توسط آنزیم نیتریک اکسید سنتتاز از l- آرژینین تولید می شود. تولید no در غلظتهای پایین با ممانعت از تولید رادیکالهای فعال اکسیژن مانع خسارات آنها می گردد. در این بررسی اثر پیش تیمار snp و arg بر تخفیف تنش خشکی در گیاه گوجه فرنگی مطالعه و...
