By Yitzhak Abt (auth.), Dov Pasternak, Arnold Schlissel (eds.)

The convention "Combating Desertification with crops" was once held in Beer Sheva, Israel, from November 2-5, 1999, and was once attended through 70 members from 30 nations and/or foreign corporations. Desertification - the degradation of soils in drylands - is a phenomenon happening in ratings of nations world wide. The variety of humans (in semiarid areas) laid low with the regular decline within the productiveness in their lands is within the hundred thousands. The measures required to halt and opposite the method of desertification fall into many different types - coverage, institutional, sociological-anthropological, and technical. even if technical "solutions" aren't at the moment fashionable, the convention organizers felt that maybe the pendulum had swung too a long way towards "participatory approaches." for this reason IPALAC - The overseas software for Arid Land plants - whose functionality is to function a catalyst for optimizing the contribution of plant germplasm to sustainable improvement in desertification-prone areas - felt the time used to be opportune for offering a platform for initiatives the place the "plant-driven" method of improvement unearths expression. a few forty five papers have been brought on the convention, falling into the types of this quantity: review, power Germplasm for Arid Lands, creation, Domestication and Dissemination of Arid Land vegetation, Land Rehabilitation, and Mechanisms of Plant move. The convention was once funded through UNESCO (Division of Ecological Sciences), the Ministry of international Affairs of Finland, and MASHAV, Israel's middle for overseas improvement Cooperation.

Post-Transcriptional Control of Gene Expression in Plants

A up to date quantity of this sequence (Signals and sign TransductionPathways in crops (K. Palme, ed. ) Plant Molecular Biology26, 1237-1679) defined the relay races in which signs are transported in vegetation from the websites of stimuli to the gene expression equipment of the mobilephone. a part of this equipment, the transcription gear, has been good studied within the final 20 years, and lots of very important mechanisms controlling gene expression on the transcriptional point were elucidated.

Probably the best way to combat poverty-induced desertification is to attempt to improve the poor farmers' economic situation. Their improved economic status will then become an effective tool which they themselves will use to fight the permeators of their poverty. The introduction of new crops and of appropriate technologies that can increase farmer's income, improve soil fertility and increase crop yield seems the best way to improve the farmer's economic situation. As illustrated in Figure 5, these crops and technologies should become the agent which will break the "vicious triangle of poverty".

TERFEZIAS, A FAMILY OF MYCORRHIZAL EDIBLE MUSHROOMS FOR ARID ZONES Varda Kagan-Zur Instutes for Applied Research, Ben-Gurion University, POB 653, Beer-Sheva 84105, Israel. il 1. 1 The Terfeziaceae family The Terfeziaceae family of fungi belongs to the Tuberales, Ascomycetes, and includes several genera of hypogeaus mushrooms, of which the better known and culinary appreciated are the genera of the Terfezias and Tirmanias, on which this presentation focuses. Members of these genera are mycorrhizal, usually occupy the same habitat, and often share the same plant hosts.
