The effect of copper on plant regeneration in barley microspore culture

Czech Journal of Genetics and Plant Breeding, 2017
Isolated microspore culture is an excellent system for the production of doubled haploids in many crops, including barley. In a more traditional barley anther culture method copper sulphate is known to enhance plant regeneration.

Comparison between Germinated Seed and Isolated Microspore EMS Mutagenesis in Chinese Cabbage (Brassica rapa L. ssp. pekinensis)

Horticulturae, 2022
Mutagenesis is an important tool for breeding and genomic research. In this study, the germinated seeds and isolated microspores of a double haploid line ‘FT’ were treated with EMS, respectively, with the aim of comparing the effects of the two ...

Triticale and barley microspore embryogenesis induction requires both reactive oxygen species generation and efficient system of antioxidative defence

Plant Cell Tissue and Organ Culture, 2021
The effectiveness of microspore embryogenesis (ME) is determined by a complex network of internal and environmental factors. In the present study on triticale and barley, strong positive correlation (r = 0.85) between the generation of hydrogen peroxide (

Rapid Generation and Analysis of a Barley Doubled Haploid Line with Higher Nitrogen Use Efficiency Than Parental Lines by F1 Microspore Embryogenesis

Plants, 2021
Creating varieties with high nitrogen use efficiency (NUE) is crucial for sustainable agriculture development. In this study, a superior barley doubled haploid line (named DH45) with improved NUE was produced via F1 microspore embryogenesis with three ...

Selaginella subeffusa, a new spikemoss from Southeast Yunnan, China

Turczaninowia, 2022
Based on extensive herbarium research of the Selaginella monospora group (incl. S. effusa, S. microclada, S. monospora, S. subdiaphana, and S. submonospora) and on molecular phylogenetic evidence, an additional new species to this group was discovered ...

Suppression of Metacaspase- and Autophagy-Dependent Cell Death Improves Stress-Induced Microspore Embryogenesis in Brassica napus

Plant and Cell Physiology, 2020
Microspore embryogenesis is a biotechnological process that allows us to rapidly obtain doubled-haploid plants for breeding programs. The process is initiated by the application of stress treatment, which reprograms microspores to embark on embryonic ...

The effect of glutathione and mannitol on androgenesis in anther and isolated microspore cultures of rye (Secale cereale L.)

Plant Cell Tissue and Organ Culture, 2020
Androgenic responsiveness in anther (AC) and isolated microspore cultures (MC) was analysed using 15 lines of Polish winter rye (Secale cereale L.).

Effects of Genotype and Culture Conditions on Microspore Embryogenesis and Plant Regeneration in Brassica Rapa ssp. Rapa L.

Plants, 2020
Turnip is a biennial crop and, consequently, the creation of pure lines for breeding is a time-consuming process. The production of pure turnip lines using doubled haploids produced in isolated microspore culture has not been sufficiently developed.

Defective Microspore Development1 is required for microspore cell integrity and pollen wall formation in rice.

The Plant Journal, 2020
Highly coordinated pollen wall patterning is essential for male reproductive development. Here, we report the identification of Defective Microspore Development1 (DMD1), which encodes a nuclear-localized protein possessing transactivation activity.
