different explants of crocus sativus l. such as corm, style, ovary, petal, anther and leaf were cultured on ls and ms media supplemented with naa and bap or 2,4-d plus bap at different combinations. shoot and corm induction occurred in addition to the formation of other organs. efficient plantlet regeneration with strong roots occurred at 1 mg 1-i of both naa and bap. an increase in 2,4-d level...

Most studies on kidney development have considered the interaction of the metanephric mesenchyme and the ureteric bud to be the major inductive event that maintains tubular differentiation and branching morphogenesis. The mesenchyme produces Gdnf, which stimulates branching, and the ureteric bud stimulates continued growth of the mesenchyme and differentiation of nephrons from the induced mesen...

To establish an efficient plant regeneration system of Cassia mimosoides, the 10-day-old seedlings were used as explants for inducing lateral buds. Results showed that addition BA and NAA different ratios on basis 1/2 MS could effectively induce production By adding additional elements, it was found growth buds longer stronger medium + 3.0 mg/l 0.1 4.0 Gln or 1.0 AgNO3. Meanwhile, cutting with ...

Irregular flowering is a serious problem in longan production. Identifying the flower induction-related genes and analyzing their regulation mechanism key to solve this problem. The APETALA2/ethylene responsive factor (AP2/ERF) superfamily members are transcription factors (TFs) that regulate diverse developmental processes, including time, stress responses plants. However, there still no resea...

Development of skin appendages requires interactions between the epithelium and mesenchyme. Without the epithelium, dermal condensations cannot develop, and those already formed will disintegrate. Here we explored the molecular basis of this epithelial requirement and tried to identify the molecule(s) responsible by using the chick feather bud development as a model. TGF beta2 is a likely candi...

Branching morphogenesis of the metanephric kidney is critically dependent on the delicate orchestration of diverse cellular processes including proliferation, apoptosis, migration, and differentiation. Sphingosine-1-phosphate (S1P) is a potent lipid mediator influencing many of these cellular events. We report increased expression and activity of both sphingosine kinases and S1P phosphatases du...

An efficient, simple micro propagation method was developed for Zingiber officinale Rosc.) cv. Volvo using fresh sprouting bud in basal culture media. Explants were cultured on to Murashige and Skoog’s (MS) medium supplemented with different concentrations combinations of BA (Benzyl adenine) KIN (Kinetin) shoot IBA (Indol-3-Butyric acid) NAA (α- Naphthalene acetic root induction. MS 2.0 mg/L + ...
