Regeneration in Sabellastarte spectabilis Chase Beal

An oxalic acid oxidase in the leaves of Bougainvillea spectabilis.

Oxalic acid undergoes enzymic transformation along diverse channels in cell-free preparations from micro-organisms and plants. In Collyvia veltepes oxalate undergoes a simple decarboxylation (Shimazono, 1955; Shimazono & Hayaishi, 1957), whereas in other micro-organisms the decarboxylation is preceded by the formation of the CoA derivative of oxalate (Jakoby, Ohmura & Hayaishi, 1956; Kimura, Ka...

Impact of the Spittlebug Mahanarva spectabilis on Signal Grass

The aim of this study was to determine the damage in Brachiaria ruziziensis (Germain & Edvard) according to the density of and exposure time to adults of Mahanarva spectabilis (Distant, 1909) (Hemiptera:Cercopidae). Each plant was kept with 0, 12, 18, or 24 adults of M. spectabilis for five or ten days. Then, the insects were removed from the plant, and the following parameters were evaluated: ...

Microsatellite markers for Senna spectabilis var. excelsa (Caesalpinioideae, Fabaceae)1

PREMISE OF THE STUDY Senna spectabilis var. excelsa (Fabaceae) is a South and Central American tree of great ecological importance and one of the most common species in several sites of seasonally dry forests. Our goal was to develop microsatellite markers to assess the genetic diversity and structure of this species. METHODS AND RESULTS We designed and assessed 53 loci obtained from a micros...

How will Mahanarva spectabilis (Hemiptera: Cercopidae) Respond to Global Warming?

The aim of this study was to determine the favorable constant temperature range for Mahanarva spectabilis(Distant) (Hemiptera: Cercopidae) development as well as to generate geographic distribution maps of this insect pest for future climate scenarios. M. spectabilis eggs were reared on two host plants (Brachiaria ruziziensis(Germain and Edvard) and Pennisetum purpureum(Schumach)), with individ...
