Population Arrangement of Crambe Plants

Phylogeography, gene Flow and Population Structure of Crambe crambe (Porifera: Poecilosclerida)

Production and genetic characterization of interspecific hybrids among Crambe abyssinica, Crambe hispanica and Crambe kralikii.

In this paper, interspecific crosses among Crambe abyssinica, Crambe hispanica, and Crambe kralikii were reported. In the C. hispanica x C. abyssinica (H x A) cross, 118 F1 hybrids were produced without embryo rescue, while 5 F1 hybrids were obtained with embryo rescue, when C. hispanica was used as the female parent. In the reciprocal cross (A x H), 232 hybrids were obtained without embryo res...

Determination of Antioxidant Activity of Crambe Cordifolia

In the present investigation, the antioxidant activity and free radical scavenging activity of Crambe cordifolia plant were spectrophotometrically studied. Free radical scavenging activity was determined by DPPH method and the obtained IC value was 1106.65 μg/mL. For comparison, the IC value of standard ascorbic acid 50 50 was 21.69 μg/mL. Antioxidant activity was determined by phosphomolybdate...

How Environmental Factors Affect the Production of Guanidine Alkaloids by the Mediterranean Sponge Crambe crambe

Most marine sponges are known to produce a large array of low molecular-weight metabolites which have applications in the pharmaceutical industry. The production of so-called specialized metabolites may be closely related to environmental factors. In this context, assessing the contribution of factors like temperature, nutrients or light to the metabolomes of sponges provides relevant insights ...

A single betaproteobacterium dominates the microbial community of the crambescidine-containing sponge Crambe crambe

Crambe crambe is a marine sponge that produces high concentrations of the pharmacologically significant pentacyclic guanidine alkaloids (PGAs), Crambescines and Crambescidines. Although bio-mimetic chemical synthesis of PGAs suggests involvement of microorganisms in their biosynthesis, there are conflicting reports on whether bacteria are associated with this sponge or not. Using 16S rRNA gene ...
