Lycium humile Phil., is an extreme halophyte plant, endemic to Argentina, Bolivia, and Chile, which grows between 2000 4000 m a.s.l. in saline wetlands environments. The aim of this work identify morpho-anatomical histochemical adaptive characteristics the vegetative organs L. linked its tolerance environments high altitude wetlands, order evaluate potential as source metabolites with commercia...

Rainfall and temperature are the primary limiting factors for optimum quality and yield of cultivated jujube (Ziziphus jujuba Mill.). Adaptation to arid and cool environments has been and remains an important goal of many jujube improvement programs. This study summarized the survey results of 116 Chinese jujube varieties grown at 33 sites in China. The objective was to identify the environment...

A new genus, Chrysonasma Park, of Lecithoceridae (Gelechioidea) is described based on C. cassiterota (Meyrick) and a new species, C. caliginosa , from the Philippines. The genus is separable from its allies by the colorful wing pattern with leaden metallic longitudinal streaks. A key to the 2 species of the genus is given. Illustrations of the imagos, forewing venation, and male and female geni...

Within the leaf of an angiosperm, the vascular system is constructed in a complex network pattern called venation. The formation of this vein pattern has been widely studied as a paradigm of tissue pattern formation in plants. To elucidate the molecular mechanism controlling the vein patterning process, we previously isolated Arabidopsis mutants van1 to van7, which show a discontinuous vein pat...

Arabidopsis inflorescence stems develop a vascular pattern similar to that found in most dicots. The arrangement of vascular tissues within the bundle is collateral, and vascular bundles in the stele are arranged in a ring. Although auxin has been shown to be an inducer of vascular differentiation, little is known about the molecular mechanisms controlling vascular pattern formation. By screeni...

Proper leaf development is essential for plant growth and development, and leaf morphogenesis is under the control of intricate networks of genetic and environmental cues. We are interested in dissecting these regulatory circuits genetically and report here the isolation of two Arabidopsis dominant mutants, abnormal shoot5-1D (abs5-1D) and abs7-1D identified through activation tagging screens. ...

Salvia rosmarinus Spenn (synonym: Rosmarinus officinalis L.) is economically and medically important grows naturally in Al-Marj (Libya). Macro, micro morphological chemical characteristics were studied. Leaf venation, leaf anatomy compounds of essential oils carried out according to traditional methods. The objective the present study provide detailed description this species. Morphological cha...

Herina dimorphica n. sp. (type locality Israel) and H. sicula n. sp. (type locality Sicily, Italy) are described and illustrated, and a new species group (the Herina dimorphica species group) is established for both species. H. dimorphica is characterized by a sexually-dimorphic wing pattern and venation. H. sicula is similar albeit not sexually-dimorphic. Almost all known Herina species are as...
