High frequency in vitro propagation of Phyllanthus amarus Schum. & Thom. by shoot tip culture.
With the aim of micropropagation of Phyllanthus amarus, an important medicinal herb, shoot tips were cultured in Murashige and Skoog's medium supplemented with kinetin/ BAP singly or in combination with IAA. Growth regulators at lower range (0.1-1.0 mg L(-1)) stimulated direct regeneration of shoots. Kinetin was superior to BAP and kinetin-IAA combination was more suitable than kinetin alone. A...
متن کاملHANABA TARANU regulates the shoot apical meristem and leaf development in cucumber (Cucumis sativus L.).
The shoot apical meristem (SAM) is essential for continuous organogenesis in higher plants, while the leaf is the primary source organ and the leaf shape directly affects the efficiency of photosynthesis. HANABA TARANU (HAN) encodes a GATA3-type transcription factor that functions in floral organ development, SAM organization, and embryo development in Arabidopsis, but is involved in suppressin...
متن کاملWater Status Related Root-to-Shoot Communication Regulates the Chilling Tolerance of Shoot in Cucumber (Cucumis sativus L.) Plants
Although root-to-shoot communication has been intensively investigated in plants under drought, few studies have examined root-to-shoot communication under chilling. Here we explored whether root-to-shoot communication contributes to the chilling-light tolerance of cucumber shoots and clarified the key signal involves in this communication. After leaf discs chilling-light treatment, the photoin...
متن کاملEthylene Production by Chilled Cucumbers (Cucumis sativus L.).
Chilling at 2.5 C accelerated the synthesis of 1-aminocyclopropane-1-carboxylic acid (ACC) and C(2)H(4) production in cucumber fruit. Skin tissue contained higher levels of ACC and was more sensitive to chilling than was cortex tissue. Accumulation of ACC in chilled tissue was detected after 1 day of chilling and remained elevated even after C(2)H(4) production started to decline. These data su...
متن کاملIn vitro induction of haploid plants in unpollinated ovules, anther and microspore culture of Cucumis sativus
In order to increase the yield of haploid cucumber plants obtained from in vitro culture of unpollinated ovules, anther and microspore, we have studied several factors: the nature and concentration of plant growth regulators, the genotypes, the flower bud lengths, and the stages of microspore development. Among the different growth regulators tested, thidiazuron (TDZ) was the best for gynogenes...
