Loss of Pathogenicity and Evidence of Horizontal Gene Transfer in Colletotrichum gloeosporioides From a Medicinal Plant. [PDF]

Mol Plant Pathol
A Colletotrichum gloeosporioides strain from Huperzia serrata lacks key pathogenicity genes CgDN3 and cap20 and has fewer pelB, pnl and pg genes. pksIII, for synthesis of huperzine A, was probably acquired by the host plant from the fungus. ABSTRACT Colletotrichum gloeosporioides is a major agricultural pathogen of crops that has also been identified ...

Induction and identification of Stylosanthes guianensis tetraploids

Genetics and Molecular Research, 2015
Stylosanthes guianensis is an elite and important forage legume species, which is extensively cultivated in tropical areas. Polyploid breeding via exposure to colchicine is a conventional and practical method to improve varieties of S. guianensis. Terminal buds of S.

Influence of storage on the chemical composition of Stylosanthes hays for equine feeding

Semina: Ciências Agrárias, 2016
During dry seasons, equines are traditionally fed hay. However, if not prepared under favorable climatic conditions and if not properly stored, hay does not preserve its nutritional value. The aim of this research was to evaluate the chemical composition

Citric acid secretion induced by aluminum in two Stylosanthes species

Biologia Plantarum, 2016
Secretion of organic acids (OAs) by roots has been suggested to be an important mechanism of Al resistance in many species. In Stylosanthes, the participation of OAs in the mechanism of Al resistance is poorly understood. We aimed to study the production

Mapping the drivers of parasitic weed abundance at a national scale: a new approach applied to Striga asiatica in the mid‐west of Madagascar

Weed Research, Volume 60, Issue 5, Page 323-333, October 2020., 2020
Abstract The parasitic weed genus Striga causes huge losses to crop production in sub‐Saharan Africa, estimated to be in excess of $7 billion per year. There is a paucity of reliable distribution data for Striga; however, such data are urgently needed to understand current drivers, better target control efforts, as well as to predict future risks.

Belowground biomass decomposition is driven by chemical composition in subtropical pastures and native rangelands

Agrosystems, Geosciences &Environment, Volume 3, Issue 1, 2020., 2020
Abstract Litter decomposition, particularly from belowground pools, is a key process controlling the flow of nutrients and the sustainability of native and cultivated grazinglands. This study evaluated in situ belowground decomposition of saw‐palmetto (Serenoa repens [W.

Agronomic performance of interspecific Paspalum hybrids under nitrogen fertilization or mixed with legumes

Agrosystems, Geosciences &Environment, Volume 3, Issue 1, 2020., 2020
Abstract Nitrogen supply and mixtures with legumes affect agronomic performance of pastures, and both practices can guide breeding decisions in Paspalum hybrids. The goals of this study were: (a) quantify herbage accumulation (HA), leaf accumulation (LA), cold tolerance, and N use efficiency (NUE) in P. plicatulum × P.

Priming of Stylosanthes seeds Condicionamento osmótico de sementes de Stylosanthes

Ciência Rural, 2012
It is estimated that 60% of the area of cultivated pasture, in the Brazilian Savannah, is degraded or in process of degradation, due to, among other causes, the lack of nitrogen.
