Root Hair Cells

Tufted rosettes of long root hairs occur in axils of young lateral roots of peanut (Arachis hypogaea L.). Analyses of serial sections of the axils of emerging lateral roots revealed multiple layers of root hair cells. The cells of the outer layer partially overlie the adjacent cells of the inner layer. When Bradyrhizobium cells with an integrated gusA gene were inoculated onto peanut roots and the roots subsequently stained with X-gluc, blue spots indicating the presence of colonies of Bradyrhizobium were observed in the axils of lateral roots. Blue spots were also observed in other areas on the root surface. Transmission electron microscopy revealed that the primary wall of the base of root hair cells has a loose construction. Upon inoculation of Bradyrhizobium, bacteria entered only between root hair cells through the middle lamella. In other areas of the root surface other than axils of lateral roots, the cells had modified walls similar to those at the base of root hair cells. However, invasion by Bradyrhizobium of the cell wall was not observed.Key words: Arachis hypogaea, gusA-marked Bradyrhizobium, cell wall, invasion, root hair cell, root nodules.

A field experiment was conducted during 2018-19 and 2019-20 to study the effect of vermicompost and foliar spray of zinc on growth, quality and productivity of groundnut (Arachis hypogaea L.) The experiment comprising of ten treatments viz., T1 (NPK), T2 (NPK +VC), T3 (NPK +VC+ Soil Zn 100%), T4 (NPK + VC+ Soil Zn 75%), T5 (NPK + foliar spray of 0.25% ZnSO4), T6 (NPK + foliar spray of 0.50% ZnSO4), T7 (NPK + foliar spray of 0.75% ZnSO4), T8 (NPK + VC + foliar spray of 0.25% ZnSO4), T9 (NPK + VC + foliar spray of 0.50% ZnSO4) and T10 (NPK + VC + foliar spray of 0.75% ZnSO4) were replicated thrice and evaluated in the randomized block design (RBD). The experimental soil was loamy sand in texture, low in N, high in available P and medium in K. Groundnut variety, RG 559-3 was tested. The results of the experiment revealed that significantly higher values of growth parameters viz., plant height and number of root nodules plant-1; yield viz., pod yield (44.3, 47.2 q ha-1) and haulm yield (54.03, 58.8 q ha-1); quality parameters viz., oil content and protein content were recorded under the treatment receiving NPK (15:60:30) +VC (5 t ha-1) + Soil Zn 100% (T3) over control (T1) while at par with the application of NPK + VC+ Soil Zn 75% (T4), NPK + VC + foliar spray of 0.25% ZnSO4 (T8), NPK + VC + foliar spray of 0.50% ZnSO4 (T9) and NPK + VC + foliar spray of 0.75% ZnSO4 (T10).

Here, we report the draft genome sequences of two nitrogen-fixing symbionts, Bradyrhizobium sp. strain sGM-13 and Bradyrhizobium sp. strain sBnM-33, isolated from root nodules of peanut grown on soil samples collected from two regions in South Tunisia. The draft genome sizes of these two strains are 8.31 × 106 bp and 8.97 × 106 bp, respectively.
