Sugar beet (Beta vulgaris L.).
Creating transgenic plants is invaluable for the genetic analysis of sugar beet and will be increasingly important as sugar beet genomic technologies progress. A protocol for Agrobacterium-mediated transformation of sugar beet is described in this chapter. Our protocol is optimized for a sugar beet genotype that performs exceptionally well in tissue culture, including the steps of dedifferentia...
متن کاملA morphogenetic crop model for sugar-beet (Beta vulgaris L.)
This paper is the instructions for the proceeding of the International Symposium on Crop. Sugar beet crop models have rarely taken into account the morphogenetic process generating plant architecture despite the fact that plant architectural plasticity plays a key role during growth, especially under stress conditions. The objective of this paper is to develop this approach by applying the Gree...
متن کاملChlorophyll Fluorescence and Photon Yield of Oxygen Evolution in Iron-Deficient Sugar Beet (Beta vulgaris L.) Leaves.
The response of sugar beet (Beta vulgaris L.) leaves to iron deficiency can be described as consisting of two phases. In the first phase, leaves may lose a large part of their chlorophyll while maintaining a roughly constant efficiency of photosystem II photochemistry; ratios of variable to maximum fluorescence decreased by only 6%, and photon yields of oxygen evolution decreased by 30% when ch...
متن کاملPlant Regeneration from Unfertilized Ovaries of Sugar Beet (Beta vulgaris L.) Cultured In Vitro
233 Abstract: A. method is described for plant regeneration from unfertilized ovaries isolated from a diploid male sterile sugar beet (Beta vulgaris L.) breeding line that was developed at the Sugar Institute, Ankara, Turkey. Ovary explants were cultured on Murashige & Skoog (MS) medium containing 2.0 mg/l benzylaminopurine (BAP). Two treatments were tested by incubating all of the explants in ...
متن کاملCharacterization of Blue-Green Fluorescence in the Mesophyll of Sugar Beet (Beta vulgaris L.) Leaves Affected by Iron Deficiency.
The mesophyll of sugar beet (Beta vulgaris L.) leaves emits red (chlorophyll a) fluorescence and blue-green fluorescence when excited with ultraviolet light. The intensity of blue-green fluorescence was increased in mesophylls affected by iron deficiency. This increase was large and progressive. It was concomitant with a decrease of photosynthetic pigments per unit of leaf area. Most of the inc...
