In vitro polyembryony induction in a critically endangered fern, Pteris tripartita Sw

Asian Pacific Journal of Reproduction, 2016
Objective: An efficient in vitro protocol was established during the development of polyembryony in the spore derived gametophyte of Pteris tripartita Sw. Methods: Sterilized spores were germinated in half strength Murashige and Skoog (MS) basal media to

Absence of Concordance between Polyembryony and Apomixis in Maize Confirmed through DNA Sequencing

Ecosistemas y Recursos Agropecuarios, 2019
Maize (Zea mays L.) polyembryony is a useful feature for genetic improvement of this specie, not only by its potential to generate multiple plants per seed, but also by its influence on increasing of fatty acids and amino acids content in the grain.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Comparative Genomics and Phylogenetics of Chloroplasts Reveal Lower Rates of Genetic Variation in Mango (<i>Mangifera</i>). [PDF]

Ecol Evol
Three highly variable sites were identified as chloroplast‐specific markers. Low rate of genetic variation in the mango chloroplast genome. Gene introgression and hybridization affect the mango genetic diversity. ABSTRACT The mango is an important economic crop with a long history of cultivation.

Status of Polyembryony in Tree Borne Oilseeds-a Review

International Journal of Bio-Resource and Stress Management, 2015
Studies on mechanism in occurrence of polyembryony are vital for understanding the fundamental aspects of biology and also for practical purpose of genetic selection. Previously, polyembryony was reported in Mango and citrus; the commercial exploitation

Radiographic analysis for the evaluation of polyembryony in Swingle citrumelo seeds

Journal of Seed Science
: The polyembryony rate is a very important factor to consider when choosing a commercial rootstock. Currently, automated systems are used to improve seed quality analyses. X-ray testing is a fast, simple, non-destructive, high-precision test that allows

Double-seedlings and embryo-free seeds generated by genetic engineering [PDF]

Frontiers in Plant Science, 2022
Apomixis can fix the heterosis of Hybrid F1, by maintaining its heterozygous genotype, and is an ideal way for the development of hybrid rice. In this paper, we designed an engineering strategy for realizing apomictic reproduction of hybrid rice in the ...

To infinity and beyond: recent progress, bottlenecks, and potential of clonal seeds by apomixis. [PDF]

Plant J
SUMMARY Apomixis – clonal seed production in plants – is a rare yet phylogenetically widespread trait that has recurrently evolved in plants to fix hybrid genotypes over generations. Apomixis is absent from major crop species and has been seen as a holy grail of plant breeding due to its potential to propagate hybrid vigor in perpetuity.

The genomic features of parasitism, Polyembryony and immune evasion in the endoparasitic wasp Macrocentrus cingulum

BMC Genomics, 2018
Background Parasitoid wasps are well-known natural enemies of major agricultural pests and arthropod borne diseases. The parasitoid wasp Macrocentrus cingulum (Hymenoptera: Braconidae) has been widely used to control the notorious insect pests Ostrinia ...
