Isolation, diversity, and biotechnological potential of rhizo- and endophytic bacteria associated with mangrove plants from Saudi Arabia

Marine bacteria have been exceptional sources of halotolerant enzymes since decades. The aim of the present study was to isolate bacteria producing hydrolytic enzymes from seven different mangroves collected from the coastal area of Thuwal, Jeddah, Saudi Arabia, and to further screen them for other enzymatic and antifungal activities. We have isolated 46 different r.. Read More»

Change in heritability estimates due to half-sib family selection in the maize variety Pahari

M. Noor, D. Shahwar, H. Rahman, H. Ullah, F. Ali, M. Iqbal, I.A. Shah and I. Ullah

This research was carried out at the Agriculture Research Farm, Khyber Pakhtunkhwa Agricultural University, Peshawar, and the Cereal Crops Research Institute, Pirsabak, Nowshera, during 2009 and 2010. Half-sib families (HS) derived from the maize variety Pahari in spring crop seasons 2009 and 2010 were developed at the Cereal Crops Research Institute. All HS families were detasseled well before..

Detection of bacterial blight resistance genes in basmati rice landraces

I. Ullah, S. Jamil, M.Z. Iqbal, H.L. Shaheen, S.M. Hasni, S. Jabeen, A. Mehmood and M. Akhter

Aromatic basmati rice is vulnerable to bacterial blight disease. Genes conferring resistance to bacterial blight have been identified in coarse rice; however, their incorporation into basmati varieties compromises the prized basmati aroma. We identified bacterial blight resistance genes Xa4, xa5, Xa7, and xa13 in 52 basmati landraces and five basmati cultivars using.. Read More»

Genetic diversity analysis of Bt cotton genotypes in Pakistan using simple sequence repeat markers

I. Ullah, A. Iram, M.Z. Iqbal, M. Nawaz, S.M. Hasni and S. Jamil

The popularity of genetically modified insect resistant (Bt) cotton has promoted large scale monocultures, which is thought to worsen the problem of crop genetic homogeneity. Information on genetic diversity among Bt cotton varieties is lacking. We evaluated genetic divergence among 19 Bt cotton genotypes using simple sequence repeat (SSR) markers. Thirty-seven of 1..
