Nodulation ability of 15 Rhizobium strains isolated from root and stem nodules of tropical Aeschynomene species was studied on 20 different Aeschynomene species and four other legumes-Arachis hypogaea, Stylosanthes guianensis, Macroptilium atropurpureum, and Sesbania rostrata. The results of this investigation showed that Aeschynomene species could be divided into three groups according to the ...

The concept of a linear increase in harvest index, dHI/dt, has proven very useful for crop simulation modeling. The effect of high temperature on the response of dHI/dt of pods and seeds of peanut (Arachis hypogaea L.) has not been described. The objectives of this work were to determine (i) whether dHI/dt was linear at high temperature, (ii) whether high temperature affected dHI/dt and/or the ...

Fusarium wilt diseases caused by the fungus Fusarium oxysporum lead to significant yield losses of crops. Biocontrol agents such asTrichoderma viride , Trichoderma harzianum and Pseudomonas fluorescens are applied to control Fusarium wilt of Arachis hypogaea. Experiments were conducted on the effect of culture filtrates of T.viride (1%), T.harzianum (1.5%), and P. fluorescens (2%) on biochemica...

Carnivorous sponges (family Cladorhizidae) lack the aquiferous system and choanocytes and, therefore, their reproduction in particular spermatogenesis is unusual for Porifera. We studied a carnivorous sponge Lycopodina hypogea using confocal microscopy, SEM TEM. In brief, L. proceeds as follows. Male cells derive from archaeocyte-like cells. During its first divisions, spermatogonia are surroun...

Diversity in 26 microsatellite loci from section Caulorrhizae germplasm was evaluated by using 33 accessions of A. pintoi Krapov. & W.C. Gregory and ten accessions of Arachis repens Handro. Twenty loci proved to be polymorphic and a total of 196 alleles were detected with an average of 9.8 alleles per locus. The variability found in those loci was greater than the variability found using morpho...

Peanut is a legume crop that belongs to the family of Fabaceae, genus Arachis, and botanically named as Arachis hypogaea. Peanuts are consumed in many forms such as boiled peanuts, peanut oil, peanut butter, roasted peanuts, and added peanut meal in snack food, energy bars and candies. Peanuts are considered as a vital source of nutrients. Nutrition plays an important role in growth and energy ...

Great efforts have been done to collect germplasm of the Arachis genus in South America, however, many regions still remain underexplored. Under hypothesis that these new and diverse populations/species Arachis, several expeditions were carried out since 2000 Bolivia, increase documentation diversity. As a first result explorations, species section with B genome is formally described. inflata c...
