The menadiol oxidase activity of Arum maculatum mitochondria has been solubilized and fractionated. A preparation has been obtained which has an increased specific activity and a greatly decreased polypeptide composition when compared to the mitochondria. This preparation retains normal inhibitor sensitivities in that the oxidation of menadiol remains insensitive to cyanide and is inhibited by ...

In deceptive pollination, insects are bamboozled into performing nonrewarded pollination. A prerequisite for the evolutionary stability in such systems is that the plants manage to generate a perfect sensory impression of a desirable object in the insect nervous system [1]. The study of these plants can provide important insights into sensory preference of their visiting insects. Here, we prese...

Pollinators have long been known to select for floral traits, but the nature of this relationship has been little investigated in trap pollination systems. We investigated the trapping devices of 15 Arum spp. and compared them with the types of insects trapped. Most species shared a similar general design of trap chamber walls covered in downward-pointing papillate cells, lacunose cells in the ...

Abstrak: Budidaya ikan nila di sawah (minapadi) merupakan potensi utama yang diangkat oleh desa wisata Kebonagung. Akan tetapi, tingginya harga pakan menjadi kendala dihadapi warga dalam pengembangan minapadi. Pakan berbasis maggot alternatif murah dengan kualitas nutrisi tinggi. Program pengabdian ini bertujuan untuk memberikan pemahaman dan keterampilan pembuatan dari dilaksanakan bersama Kar...

The evidence for the operation of the tricarboxylic acid cycle in the metabolism of plant mitochondria has been based mostly on studies of oxidative activity. The oxidation of diand tricarboxylic acids of the cycle was demonstrated in a variety of tissues, such as etiolated seedlings of mung bean (22), pea (10, 31), Avena (32), and Black Valentine bean (4), lupin cotyledons (7), castor-bean end...
