Sesarmid crabs are reported to dominate the Indo West-Pacific mangroves and consume huge amounts of mangrove leaves and detritus. Neosarmatium trispinosum Davie (1994) is common in the landward mangroves of the Ryukyu Islands in southern Japan. Stomach contents of the crabs collected from Okinawa, Miyako and Iriomote Islands showed that their diet consisted of mainly mangrove leaves with small ...

The sink-source conversion in developing leaves of tobacco (Nicotiana tabacum L.) was studied to determine whether import termination is caused by the onset of export or is related to achievement of positive carbon balance. Albino shoots were grown in vitro and grafted to detopped stems of green tobacco plants. Termination of import was studied by providing mature leaves of the stock plant with...

The relative amounts of chloroplast tRNAs(Leu), tRNA(Glu), tRNA(Phe), tRNAs(Thr), and tRNA(Tyr) and of chloroplastic and cytoplasmic aminoacyl-tRNA synthetases were compared in green leaves, yellowing senescing leaves, and N(6)-benzyladenine-treated senescing leaves from bean (Phaseolus vulgaris, var Contender). Aminoacylation of the tRNAs using Escherichia coli aminoacyl-tRNA synthetases indic...

Description and Constituents Tea is one of the most widely consumed beverages in the world today, second only to water, and its medicinal properties have been widely explored. The tea plant, Camellia sinensis, is a member of the Theaceae family, and black, oolong, and green tea are produced from its leaves. It is an evergreen shrub or tree and can grow to heights of 30 feet, but is usually prun...

Acacia constricta, "WHITETHORN ACACIA" Drought tolerant, deciduous, Southwest native small tree or large shrub w/ spiny branches & tiny, feathery leaves; flowers are fragrant, yellow bottlebrushes produced summer. [7] (H*W*S*) Acacia greggii, "CATCLAW ACACIA" Drought tolerant, deciduous small tree/large shrub w/ spiny branches & tiny, ferny leaves; flowers are fragrant, creamy yellow bottle-bru...

Green and white leaves of the barley mutant line ;albostrians' were compared for their polar lipid content and fatty acid composition. The mutant plastids of the white leaves have a double-layered envelope, but in contrast with the normal chloroplasts, lack 70 S ribosomes and thylakoids. In the green leaves, the amount of monogalactosyldiacylglycerol (MGDG) consistently exceeds the amount of di...

The trophic role of the sea urchin Lytechinus variegatus (Lamarck) and the importance of epiphytes as mediators of trophic interactions were evaluated in a Thalassia testudinum meadow, St. Joseph Bay, Florida, in fall 2010. Tethering experiments were deployed within the meadow to assess consumption rates, and food choice experiments, with combinations of different types of T. testudinum leaves,...

There is a huge demand of silver nanoparticles in the global market due to their special properties and applications in different fields such as nanomedicine , dentists , nanocatalysis, nanoelectronics, textile field, waste water treatment.The major cons of top down and Bottom up methods are the synthesis processes are highly costly, time consuming and many harmful chemicals are used. To reduce...

Plants growing in high-light environments during winter often exhibit leaf reddening due to synthesis of anthocyanin pigments, which are thought to alleviate photooxidative stress associated with low-temperature photoinhibition through light attenuation and/or antioxidant activity. Seasonal high-light stress can be further exacerbated by a limited photosynthetic capacity, such as nitrogen-defic...

Arabidopsis ubiquitin ligases ATL31 and homologue ATL6 control the carbon/nitrogen nutrient and pathogen responses. A mutant with the loss-of-function of both atl31 and atl6 developed light intensity-dependent pale-green true leaves, whereas the single knockout mutants did not. Plastid ultrastructure and Blue Native-PAGE analyses revealed that pale-green leaves contain abnormal plastid structur...
