Rapid Genetic Stabilisation of Transgenic and Edited Wheat Through Transformation of Immature Haploid Embryos

Plant Biotechnology Journal, EarlyView.
ABSTRACT Wheat is one of the globally important food crops, but its genetically modified application lags behind other staple crops due to its complex genome and low transformation efficiency. Normally, traditional transgenic and gene‐edited wheat requires multiple selfing generations for obtaining homozygous lines, which delayed the development of ...

Pollen grain of barley (Hordeum vulgare L.) - pattern of development

Acta Societatis Botanicorum Poloniae, 2014
Pollen development in barley follows the general pattern established for other species of Poaceae: 1) microspore division occurs at the vacuolate microspore stage with polarly located nucleus; 2) microspore mitosis is immediately followed by phragmoplast

Expression of a Bacterial Trehalose 6‐Phosphate Synthase Gene otsA in Camelina sativa Seeds Promotes the Channelling of Carbon Towards Oil Accumulation

Plant Biotechnology Journal, EarlyView.
ABSTRACT Improving seed oil yield is essential for developing Camelina sativa as a sustainable biofuel crop. Fatty acid synthesis depends on the production of acetyl‐CoA from photosynthetically derived sugars. Trehalose 6‐phosphate (T6P), a proxy for sucrose availability, can link sugar status to plant growth and development. Synthesised by trehalose 6‐

Microspore embryogenesis in Apiaceae

Plant Cell, Tissue and Organ Culture (PCTOC), 2010
Haploid technology is used to develop uniform, true-breeding lines, as well as to accelerate crop improvement programs. Among 20 Apiaceae species screened for response to doubled haploidy, 11 generated microspore-derived embryos, and all but one of the latter yielded doubled haploid plants.

TaRIP2 Positively Regulates Wheat Pollen Wall Formation Through MYB80‐Controlled Lipid Metabolism

Plant Biotechnology Journal, EarlyView.
ABSTRACT Male‐sterile genes and mutants are critical for hybrid seed production in monocotyledonous crops. Lipids are essential structural components of male reproductive organs, such as the anther and pollen. Here, we show that the pollen‐preferential gene TaRIP2 is essential for wheat anther development and pollen formation. RT‐qPCR analysis revealed

Comparison of methods for obtaining doubled haploids of carrot

Acta Societatis Botanicorum Poloniae, 2017
Doubled haploid lines of carrot can be obtained through androgenesis in anther cultures and in isolated microspore cultures. The two methods were compared using three carrot cultivars (‘Kazan F1’, ‘Feria F1’, and ‘Narbonne F1’) at the androgenesis ...

Genotypes-Independent Optimization of Nitrogen Supply for Isolated Microspore Cultures in Barley

BioMed Research International, 2016
To establish a high-efficiency system of isolated microspore culture for different barley genotypes, we investigated the effects of nitrogen sources and concentrations on callus induction and plant regeneration in different barley genotypes.

Haploid Mutation Mapping Identifies a Homoeologous Non‐Reciprocal Translocation Linked to Reduced Fibre and Enhanced Protein in Brassica napus

Plant Biotechnology Journal, EarlyView.
ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.
