Bast-Sap in Plants

Characterization of phloem-sap transcription profile in melon plants.

The phloem's role as a tissue responsible for the distribution of photoassimilates and nutrients among the various organs of higher plants has long been recognized. Recent studies have established that numerous proteins and mRNA molecules are also present in the phloem translocation stream; however, limited information is available on the identity of transcripts present within the phloem sap. I...

Sap concentrations in halophytes and some other plants.

Freezing point depression in xylem sap of mangroves was found to range from 0.05 to 0.5 degrees , in desert plants from 0.01 to 0.16 degrees . In crush juices from leaves of Batis and Salicornia, 90% or more of the freezing point depression was made up of sodium and chlorine ions; in mangroves they constituted 50 to 70%, the rest probably being organic solutes. Plants growing in seawater have -...

Flexible Protocol Composition in Bast

This paper presents Bast, an object-oriented library of reliable distributed protocols. We show how Bast can be used to build fault-tolerant distributed applications , and how new protocols can be added to it. We discuss some distributed protocol design issues and the way these issues are circumvented in Bast. We brieey describe our Smalltalk and Java implementations of Bast, together with some...

The BAST algorithm for transit detection

Context. The pioneer space mission for photometric exoplanet searches, CoRoT, steadily monitors about 12000 stars in each of its fields of view. Transit detection algorithms are applied to derive promising planetary candidates, which are then followed-up with ground-based observations. Aims. We present BAST (Berlin Automatic Search for Transits), a new algorithm for periodic transit detection, ...
