Role of belowground parts of green manure legumes, Crotalaria spectabilis and Sesbania rostrata, in N uptake by the succeeding tendergreen mustard plant.

Abstract: Using symbiotically N2-fixing legumes as green manures is a way to supply N from the atmosphere to cropping ecosystems. Usually whole plants of the green manure are incorporated into soil; hence, the belowground parts as well as the aboveground parts would contribute to N transfer to succeeding crops. However, little is known about the contribution of the belowground parts alone. We assessed N transfer from belowground parts compared to whole plants of two legumes, Crotalaria spectabilis and Sesbania rostrata. Each of the legumes was grown approximately for 3 months in a 1/2000a Wagner pot filled with soil media, and then the roots alone (R) or shoot and root (S + R) were harvested and incorporated in the pots. Tendergreen mustard (Brassica rapa) as the succeeding crop was grown for 66 days in these pots without additional fertilizer. Although the amount of N in green manure in S + R pots was approximately 4-fold higher than that in R pots, differences in N uptake by tendergreen mustard between the S + R ...

Non-uniform, patchy stomatal closure of a plant is a strong determinant of plant growth under stressful situation

Abstract: The stomatal response of cassia (Cassia streata L.) and dhaincha (Sesbania rostrata L.) to a coalmine overburden (OB) substrate was studied with a view to rehabilitate such areas. Plants raised in unmined soil were used as controls. The mine OB induced significant increase in stomatal index (SI) with diminished stomatal size and a stomatal closure in the test plants. The leaf water status measured as water content was significantly enhanced, while the relative growth rate was markedly reduced. This is indicative of slow but sustainable growth of the species in mine OB adverse conditions.

Functional nodFE genes are present in Sinorhizobium sp. strain MUS10, a symbiont of the tropical legume Sesbania rostrata.

Abstract: We have cloned the nodFE operon from Sinorhizobium sp. strain MUS10. MUS10 NodF shows sequence homology to acyl carrier protein and enables an S. meliloti nodF mutant to effectively nodulate alfalfa. Our results demonstrate the occurrence of nodFE in a symbiont that nodulates a legume host not belonging to the galegoid group.

Antibacterial Activity of the Fatty Acid Methyl Esters from Synthesis of Sesbania Rostrata Seed by in-Situ Transesterification Reaction

Abstract: Summary The antibacterial activity of the fatty acid methyl esters from synthesis of Sesbania rostrata Seed by In-Situ Transesterification reaction was evaluated at two different concentrations by the agar well diffusion method. The synthesis of fatty acid methyl esters Sesbania rostrata Seed was most active against Pseudomonas pseudoalcaligenes. The synthesis of fatty acid methyl esters Sesbania rostrata Seed was more active against Gram-negative bacteria as compared to Gram-positive. The results obtained indicated that fatty acid methyl esters Sesbania rostrata Seed different antimicrobial activity.
