A foliar spray of 10 mm cyclohexanecarboxylic acid (CHC), a component of the growth stimulant naphthenic acid, to primary leaves of 14-day-old plants of bush bean, Phaseolus vulgaris L., cv Top Crop, resulted in increased vegetative growth and pod production. One minute after the application of 0.5 mm CHC-7-(14)C (CHC(*)) to a primary leaf, CHC(*) was present within it. The chief conversion of ...

Abstract The leaves of different species the genus Artemisia show considerable inner and external structural diversity. This paper presents a comparative study micromorphological features leaf surface for seven from regions Ukraine: A. absinthium L., annua dracunculus marschalliana Spreng., vulgaris argyi H.Lév. & Vaniot, verlotiorum Lamotte. vegetative organs these plants have potentially ...

Leaves are determinate organs that arise from the flanks of the shoot apical meristem as polar structures with distinct adaxial (dorsal) and abaxial (ventral) sides. Opposing regulatory interactions between genes specifying adaxial or abaxial fates function to maintain dorsoventral polarity. One component of this regulatory network is the Myb-domain transcription factor gene ASYMMETRIC LEAVES1 ...

Turgor-mediated leaf movements of the legume Samanea saman are associated with the migration of K(+) and Cl(-) between opposing sides of the motor organs (pulvini). We have investigated the pathway of this ion migration by localizing K(+) and Cl(-) within the secondary pulvinus at various times during leaf movements. Ion distributions in freeze-dried cryosections of pulvini were determined by s...

This paper presents an analysis of the morphological and anatomical characteristics aboveground parts (herba) clary sage (Salvia sclarea L.), with emphasis on investigation its surface structures. After procedure primary processing drying plant material, it was determined that composition crushed herbal drug Salviae sclareae herba showed presence leaves, bracts, flowers axis inflorescence, stem...

background: reptiles, especially turtles that inhabit both on land and water, have made some special adaptations. many people keep turtles as pets. therefore, the anatomical knowledge of turtles should be more carefully evaluated and used for therapeutic purposes. one of these turtles is european pond turtle (emys orbicularis). most of vital systems are enclosed by the carapace and the plastron...

The expression of invertases was analyzed in vegetative organs of well-watered and water-stressed maize (Zea mays) plants. Early changes in sucrose metabolism and in acid soluble invertase expression were observed in vegetative sink and source organs under mild water stress. The organ-specific induction of acid invertase activity was correlated with an increase in the Ivr2 gene transcripts and ...

Arabidopsis cDNA microarray analysis was performed for 5,722 genes using leaf, stem, root and flower mRNA as targets. We identified 55, 22, 21, and 131 genes expressed specifically in leaves, stems, flowers and roots, respectively. Statistical cluster analysis revealed that the roots were the most distant and the leaves and flowers the most related organs with regards to gene expression. K-mean...

The shoot apical meristem comprises an organized cluster of cells with a central region population of self-maintaining stem cells providing peripheral region cells that are recruited to form differentiated lateral organs. Leaves, the principal lateral organ of the shoot, develop as polar structures typically with distinct dorsoventrality. Interdependent interactions between the meristem and dev...
