Effects of different concentrations of IAA (0, 0.3, 0.6 mg/l) and 2ip (0, 0.3, 0.6, 0.9, 1.2 mg/l) and their combinations on callus induction and shoot regeneration of hypocotyl and its thin cell layer (TCL) explants in tomato was studied. Explants were prepared from hypocotyls of seedlings in the aseptic condition. Hypocotyl segments were more efficient than TCL explants for callus induction a...

Tcl[1] is an interpreted high level language suitable for scripts, small scale systems, prototypes and embedding in larger applications. C++ is a powerful compiled language that provides support for object oriented programming and is suitable for building large complex systems. But what if you could move from C++ to Tcl and back again with the ease of an object reference and a dynamically bound...

Tcl-DP is a loadable module for Tcl that adds advanced communication features to Tcl/Tk. Tcl-DP supports communication by serial links, IP-multicast, TCP, UDP, and email, contains a remote procedure call (RPC) mechanism, and supports the design of new protocols using modules called filters. Tcl-DP 1.0 [Smi93] was released four years ago and has since been used for numerous commercial and academ...

The TCL-1 gene maps at chromosome 14q32.1 and is activated in T cell leukemias and lymphomas by either chromosome translocations or inversions that juxtapose the TCL-1 gene to the alpha/delta or the beta locus of the T cell receptor. The open reading frame of the TCL-1 gene, coding for a protein of 114 amino acids, was expressed in bacteria and antisera were raised against it. The antibodies re...

Tcl is not thread-safe. If two or more threads attempt to use Tcl at the same time, internal data structures can be corrupted and the program can crash. This is true even if the threads are using separate Tcl interpreters. PtTcl is a modi cation to the Tcl core that makes Tcl safe to use with POSIX threads. With PtTcl, each thread can create and use its own Tcl interpreters that will not interf...

This paper describes an approach to designing and building Tcl extensions that can be flexibly and dynamically changed using either Tcl or C. In particular, extensions having an object-based interface are considered. This extension approach seeks to avoid the “chasm” found in migrating code from Tcl to C as it matures by freely mixing Tcl and C to create an object’s subcommands. The approach di...

BACKGROUND Canine T-cell lymphoma (TCL) is conventionally considered an aggressive disease, but some forms are histologically and clinically indolent. CD4 TCL is reported to be the most common subtype of TCL. We assessed flow cytometric characteristics, histologic features when available, and clinical outcomes of CD4+ TCL to determine if flow cytometry can be used to subclassify this group of l...

The frequency of movement of Tcl, a 1.6kilobase transposable element in the nematode Caenorhabditis elegans, is under genetic control, and Tcl insertion sites are widely but nonrandomly distributed. The unusually high frequency of insertions at multiple sites in the gene unc-22 suggested that this gene might be particularly rich in preferred target sites. To discover the features of Tcl target ...

Expect is a tool for automating interactive applications. Expect was constructed using Tcl, a language library designed to be embedded into applications. This paper describes experiences with Expect and Tcl over a seven year period. These experiences may help other extension designers as well as the Tcl developers or developers of any other extension language see some of the challenges that a s...
