TETRAPLOIDY AND OCTOPLOIDY INDUCED BY COLCHICINE IN DIPLOID PETUNIA

Tetraploidy Induced by Electrofusion - A Review

| In vitro tetraploid embryo production has turn into an inestimable means in various research studies for researchers since last few years. The natural tetraploidy stage in embryo is exceptionally reported; hence different techniques have been engaged to bring the tetraploidy experimentally in mammals. There are three fundamental techniques to induce tetraploidy in vitro. First technique is th...

Oryzalin-induced Tetraploidy in Cryptomeria japonica (Cupressaceae)

Japanese-cedar [Cryptomeria japonica (L.f.) D. Don] represents an alternative to leyland cypress [·Cuprocyparis leylandii (A.B. Jacks. & Dallim.) Farjon] as an evergreen screen or specimen plant for landscapes. It performs well under a range of soil and environmental conditions but has been underused attributable, in part, to unsightly winter browning caused by photoinhibition. In previous stud...

Proteomic Analysis of the Low Mutation Rate of Diploid Male Gametes Induced by Colchicine in Ginkgo biloba L.

Colchicine treatment of G. biloba microsporocytes results in a low mutation rate in the diploid (2n) male gamete. The mutation rate is significantly lower as compared to other tree species and impedes the breeding of new economic varieties. Proteomic analysis was done to identify the proteins that influence the process of 2n gamete formation in G. biloba. The microsporangia of G. biloba were tr...

Retinal atrophy induced by intravitreous colchicine.

Colchicine is known to inhibit axoplasmic transport in ganglion cells. Previous studies have shown considerable, but largely reversible, retinal changes after low dosages of intravitreal colchicine in experimental animals. In the present study, the effects of 1.0 to 100 micrograms of intravitreal colchicine in monkeys were studied by ophthalmoscopy, light microscopy, and electron microscopy. Op...
