A rapid technique for trichothecene detection was needed in screening tests of the potential bioherbicide Myrothecium verrucaria (MV), in order to select strains, mutants, or formulations that were void of or that possessed low amounts of these undesirable mycotoxin compounds. Commercially available enzymelinked immunosorbent assay (ELISA) plates for trichothecene detection, possessing cross-re...

Colletotrichum truncatum, a potential mycoherbicide for control of hemp sesbania, formed spontaneous variants on agar medium. The predominant variant produced more spores than the wild type on potato dextrose agar but the wild type produced more spores on Czapek-Dox agar. Spore yield of both types was greatly reduced on Czapek-Dox. In liquid culture, the variant spontaneously arose and graduall...

The objective of this study was to assess the effect mix-cropping, Yangtsepa corn variety with legume Sesbania, and single cropping on forage yield quality at 60-, 90-, 120-days harvest. Randomized Complete Block Design (RCBD) three replications used as an experimental design. pea were line sown 20 cm apart a seed ratio 50:50. results showed higher (26.1 t/ha), dry matter 23.83% 120-day overall...

Three isoflavanoids, isovestitol (1), medicarpin (2), and sativan (3), along with another known compound, betulinic acid (4), were isolated from the root of Sesbania grandiflora. The structures of the isolated compounds were characterised by means of spectroscopic techniques (UV, IR, MS, 1H- and 13C-NMR, DEPT, COSY, HMQC, HMBC, and MS analysis). All the tested compounds 1-4 exhibited antituberc...

I have measured acetylene diffusion through plant tissues including nodules from several species of legume-vetch, peas, soybeans, and Sesbania rostrata. The observed half-time for reequilibration of internal and external concentration is less than 1 minute for typical nodules. Inward diffusion of acetylene in air is rapid relative to the use of acetylene by nitrogenase so that diffusion of acet...

A novel marker for the early stages of nodulation of Sesbania rostrata was found to encode a putative member of the Kunitz family of protease inhibitors (SrPI1). Its expression was enhanced during nodulation, and was not up-regulated by wounding or upon infection with wide host-range pathogens. In situ expression patterns resembled those previously described for functions that may be implicated...
