This study was conducted Razakı grape variety (Vitis vinifera L.) and its vine which was aged 19 was grown on 5 BB rootstock in a vegetation period of 2014 in Afyon province in Turkey. In this research, it was investigated whether the applications of Control (C), 1/3 Cluster Tip Reduction (1/3 CTR), Shoot Tip Reduction (STR), 1/3 CTR + STR, Boric Acid (BA), 1/3 CTR + BA, STR + BA, 1/3 CTR + STR...

bean yellow mosaic virus (bymv, potyvirus, potyviridae) causes serious disease in gladiolus spp. in this work, the possibility of obtaining bymv free plant material from virus infected gladiolus corms was studied. thermotherapy, meristem-tip culture and combination of both techniques on infected corms/meristem-tip explants (0.5–1 mm in length) resulted in bymv elimination up to 15.38, 78.04 and...

Chrysanthemum stunt viroid (CSVd) can infect Argyranthemum and cause serious economic loss. Low temperature treatment combined with meristem culture has been applied to eradicate viroids from their hosts, but without success in eliminating CSVd from diseased Argyranthemum. The objectives of this work were to investigate (1) the effect of low temperature treatment combined with meristem culture ...

Tropane alkaloids, especially hyoscyamine (HYO) and scopolamine (SCO), are widely used in medicine for their antispasmodic, anticholinergic, and sedative properties. This study was undertaken to investigate the root and shoot tropane alkaloids production from in vitro shoot tip (as explant) culture of Hyoscyamus niger under different plant growth regulators including auxins (IAA, 2, 4-D, IBA, N...

A rapid in vitro propagation system has been established from mature shoot tip and nodal segments of ahighly valuable medicinal plant Alternanthera sessilis (L.). The explants were cultured on Murashige andSkoog’s medium augmented with different concentrations and combinations of plant growth regulators forshoot bud initiation and multiplications. For shoot tip, highest freque...

alpha,alpha-Trehalose induced a rapid blackening of the terminal 2.5-centimeter region of excised Cuscuta reflexa Roxb. vine. The incorporation of radioactivity from [(14)C]glucose into alkali-insoluble fraction of shoot tip was markedly inhibited by 12 hours of trehalose feeding to an excised vine. This inhibition was confined to the apical segment of the vine in which cell elongation occurred...

The shoot apical meristem (SAM) is a collection of stem cells that resides at the tip of each shoot and provides the cells of the shoot. It is divided into functional regions. The central zone (CZ) at the tip of the meristem is the domain of expression of the CLAVATA3 (CLV3) gene, encoding a putative ligand for a transmembrane receptor kinase, CLAVATA1, active in cells of the rib meristem (RM),...

Small shoot bud galls induced by the Fergusobia (Nematoda: Neotylenchidae)/Fergusonina (Diptera: Fergusoninidae) mutualism occur on various Eucalyptus spp. Four new species of Fergusobia, collected from small shoot bud galls on Eucalyptus camaldulensis, E. gomphocephala and E. leucoxylon, are described. Fergusobia gomphocephalae Davies n. sp. is morphologically characterized by a combination of...
