Subcutaneous inoculation of 1 ml of ground Theileria annulata tick tissue stabilate (0.75 tick equivalent) into crossbred calves (n = 6, average age 53 days) resulted in the development of acute theileriosis. The percentage parasitaemia was 71.7%±3.3% on day 20 after inoculation. Macroschizonts were observed in lymphocytes and monocytes. Phagocytosed(More)
Bacterial Blight (BB) caused by Xanthomonas oryzae pv. oryzae is a major disease of rice in tropical Asia. Since all the Basmati varieties are highly susceptible and the disease is prevalent in the entire Basmati growing region of India, BB is a severe constraint in Basmati rice production. The present study was undertaken with the objective of combining(More)
Administration of ground-up tick tissue stabilate (0.75 tick equivalent) by the subcutaneous route to crossbred calves aged 1 week to 1 month led to the development of acute theileriosis. Haematological studies revealed significant progressive decreases in haemoglobin concentration, packed cell volume and red blood cell count, whereas the total leukocyte(More)
Pusa RH10, the widely cultivated superfine grain aromatic rice hybrid, and its parental lines Pusa6B and PRR78 are susceptible to bacterial blight (BB) disease caused by Xanthomonas oryzae pv. oryzae. Pusa1460, a Basmati rice variety, was utilized as the donor for introgressing BB resistance genes xa13 and Xa21 into Pusa6B and PRR78 using a marker-assisted(More)
Grain protein concentration (GPC) is one of the most important factors influencing pasta-making quality. Durum wheat (Triticum turgidum L. var durum) cultivars with high GPC produce pasta with increased tolerance to overcooking and greater cooked firmness. However, the large environmental effect on expression of GPC and the negative correlation with grain(More)
The full-length genome of a begomovirus and its cognate DNA-β satellite component associated with chilli leaf curl disease (ChLCD), originating from Varanasi, India, were cloned. Sequence analysis revealed that the viral genome (EF190217) is 2,750 bp and the DNA-β satellite (EF190215) is 1,361 bp in length. Agroinoculation with partial tandem repeats of the(More)
The yellow pigment (YP) of durum wheat (Triticum turgidum L. var durum) semolina is due in part to the presence of carotenoid pigments found in the endosperm and is an important end-use quality trait. Phytoene synthase (Psy) is considered a rate-limiting enzyme in the carotenoid biosynthetic pathway and in this study, three alleles of Psy1-A1 were sequenced(More)
Leaf rust (Puccinia triticina Eriks.), stripe rust (Puccinia striiformis f. tritici Eriks.) and stem rust (Puccinia graminis f. sp. tritici) cause major production losses in durum wheat (Triticum turgidum L. var. durum). The objective of this research was to identify and map leaf, stripe and stem rust resistance loci from the French cultivar Sachem and(More)
Preharvest sprouting reduces grain quality and lowers grade. Characterization of preharvest sprouting resistance is important in selection in breeding for transgressive segregation and understanding the genetics of the trait for identifying QTL. Methods of measuring dormancy and other factors contributing to preharvest sprouting resistance are varied. The(More)
In wheat, advantageous gene-rich or pleiotropic regions for stripe, leaf, and stem rust and epistatic interactions between rust resistance loci should be accounted for in plant breeding strategies. Leaf rust (Puccinia triticina Eriks.) and stripe rust (Puccinia striiformis f. tritici Eriks) contribute to major production losses in many regions worldwide.(More)
