1. Cultivo de Leptochloa Fusca para a utilização de solos afetados por sais e recursos hídricos no Deserto de Cholistan
No Deserto de Cholistan, 0,44 milhões de hectares são afetados por condições de solos rasos, salinos e argilosos por natureza, sendo localmente conhecidos como 'dhars', onde a água da chuva, bem como as águas subterrâneas salinas poderiam ser utilizadas para o cultivo de gramíneas tolerantes a sais, como a Leptochloa fusca, como forragem durante o ve

2. Strain-specific chemotaxis of Azospirillum spp.
Chemotactic responses of three Azospirillum strains originating from different host plants were compared to examine the possible role of chemotaxis in the adaptation of these bacteria to their respective hosts. The chemotaxis to several sugars, amino acids, and organic acids was determined qualitatively by an agar plate assay and quantitatively by a channele

3. Close Association of Azospirillum and Diazotrophic Rods with Different Root Zones of Kallar Grass
The populations of diazotrophic and nondiazotrophic bacteria were estimated in the endorhizosphere and on the rhizoplane of Kallar grass (Leptochloa fusca) and in nonrhizosphere soil. Microaerophilic diazotrophs were counted by the most-probable-number method, using two semisolid malate media, one of them adapted to the saline-sodic Kallar grass soil. Plate

4. Root-Zone-Specific Oxygen Tolerance of Azospirillum spp. and Diazotrophic Rods Closely Associated with Kallar Grass
The effect of oxygen on N2-dependent growth of two Azospirillum strains and two diazotrophic rods closely associated with roots of Kallar grass (Leptochloa fusca) was studied. To enable precise comparison, bacteria were grown in dissolved-oxygen-controlled batch and continuous cultures. Steady states were obtained from about 1 to 30 μM O2, some of them bein

5. Root colonization and systemic spreading of Azoarcus sp. strain BH72 in grasses.
The invasive properties of Azoarcus sp. strain BH72, an endorhizospheric isolate of Kallar grass, on gnotobiotically grown seedlings of Oryza sativa IR36 and Leptochloa fusca (L.) Kunth were studied. Additionally, Azoarcus spp. were localized in roots of field-grown Kallar grass. To facilitate localization and to assure identity of bacteria, genetically engi
