α-Tomatine was not highly phytotoxic and slightly inhibited the stem elongation (7 to 13%) when applied as a spray to etiolated 4-day-old seedlings of sesbania [Sesbania exaltata (Raf.) Rybd.], sicklepod (Senna obtusifolia L.), mungbean (Vigna radiata L.), wheat (Triticum aestivum L.) and sorghum (Sorghum vulgare L.). Tomatidine had less effect on stem elongation than tomatine and reduced the e...

Aminomethylphosphonic acid (AMPA) is the most frequently detected metabolite of glyphosate in plants. The objective of this study was to determine if there is any correlation of metabolism of glyphosate to AMPA in different plant species and their natural level of resistance to glyphosate. Greenhouse studies were conducted to determine the glyphosate I 50 values (rate required to cause a 50% re...

Sesbania mosaic virus (SeMV) is a positive stranded RNA virus belonging to the genus Sobemovirus. Construction of an infectious clone is an essential step for deciphering the virus gene functions in vivo. Using Agrobacterium based transient expression system we show that SeMV icDNA is infectious on Sesbania grandiflora and Cyamopsis tetragonoloba plants. The efficiency of icDNA infection was fo...

The study was conducted at the On Farm Research Division (OFRD) farm, Rangpur from 2002-2003 to 2004-2005 to see the effect of inorganic fertilizers along with organic manure and mungbean residue on soil properties and yield of crops. For the first crop (maize), there were five treatments. After harvest of maize, mungbean and dhaincha (Sesbania) seeds were sown as per treatments. For T. Aman ri...

Field samples and seedlings of 51 leguminous forage species were tested for alfalfa mosaic virus (AMV) in routine monitoring of seed multiplication fields of the International Livestock Research Institute (ILRI), Ethiopia. The virus was detected in 24 species and a solanaceous weed Solanum nigrum . Of these, the following 17 species are being reported for the first time as hosts of the virus in...

A total of 57 colonies of Agrobacterium species was isolated from the root nodules of five different leguminous plant namely Pisum sativum, Sesbania rostrata, Vigna mungo, V. radita and V. ungiculata by using yeast extract mannitol agar (YEMA). All the isolated colonies were belonged to Agrobacterium species. The isolated bacteria were characterized and identified as Agrobacterium rhizogenes ba...

Sesbania Grandiflora (Family: Leguminosae) is a medicinal plant used as tumor suppressant agent in Ayurveda, a traditional system of medicine practiced in sub-continental India. The aim of the study was to systematically investigate and reveal the cytotoxic potential of sesbania grandiflora bark extract [petroleum ether (BP), Chloroform (BC), Methanol extract (BM) and Aqueous extract (BA)] agai...

The bioherbicidal fungus, Colletotrichum truncatum (Schwein.) Andrus & Moore, was tested at different inoculum concentrations alone and in combination with, prior to or following treatment with different rates of glyphosate (N-[phosphonomethyl]glycine) (Roundup Ultra) for the control of hemp sesbania (Sesbania exaltata [Raf.] Rydb. ex A.W. Hill) in Roundup Ready soybean field plots. Colletotric...

Some of the parameters that determine flooding resistance-and consequently habitat zonation-were investigated in four neotropical trees (Schizolobium parahyba, Sebastiania commersoniana, Erythrina speciosa and Sesbania virgata). The constitutive parameters of seeds (size, nature and amount of reserves) only partly influenced resistance to flooding, mainly through a high carbohydrate : size rati...
