Expression Profiling of MSP1 Gene Involved in Mega-gametophyte Development in Ploidy Series of Guinea Grass (Panicum maximum Jacq.)

Journal of Advances in Biology & Biotechnology
Hybrid seeds are playing important role in increasing agricultural production. However, process of hybrid seed development involves high cost for most of the major crops.

Transcriptome Analysis of Differentially Expressed Genes at Pre-Meiotic Developmental Stage in Pennisetum Hybrids with Contrasting Modes of Reproduction [PDF]

, 2020
Apomixis is an asexual reproduction through seeds where embryo develops without meiosis and fertilization. It is widely distributed throughout plant kingdom, but is more prevalent in families like Asteraceae, Rosaceae and Poaceae (Carman, 1997).

Sexual reproduction is the default mode in apomictic Hieracium subgenus Pilosella, in which two dominant loci function to enable apomixis.

The Plant Journal, 2011
Asexual seed formation, or apomixis, in the Hieracium subgenus Pilosella is controlled by two dominant independent genetic loci, LOSS OF APOMEIOSIS (LOA) and LOSS OF PARTHENOGENESIS (LOP).

Sporophytic ovule tissues modulate the initiation and progression of apomixis in Hieracium [PDF]

, 2012
Apomixis in Hieracium subgenus Pilosella initiates in ovules when sporophytic cells termed aposporous initial (AI) cells enlarge near sexual cells undergoing meiosis.

Effects of Plant Stress on Facultative Apomixis in Boechera (Brassicaceae) [PDF]

, 2015
In flowering plants, apomixis is asexual reproduction by seeds. Apomixis allows the production of offspring with the same genetic characteristics as the mother plant. Fertilization is not required.

Ploidy Dependent Expression of Apomixis Components in Guinea Grass (\u3cem\u3ePanicum maximum\u3c/em\u3e Jacq.) [PDF]

, 2020
Apomixis is an asexual method of reproduction through seeds. The potential of apomixis has been envisaged as “asexual revolution” by virtue of its capacity to fix hybrid vigour, a much desirable feature in breeding of agricultural crops.

Pharmacologically Induced Meiosis Apomeiosis Interconversions in Boechera, Arabidopsis and Vigna

, 2018
Apomixis is a clonal propagation method that produces offspring identical to the mother plant. With this feature, superior traits could be maintained over generations. However, our knowledge about apomixis is limited. In this study, we analyzed several apomictic Boechera embryologically to learn the details of apomixis.

Apomixis: an enigma with potential applications [PDF]

, 2005
Apomixis has been the focus of research in plant sciences in recent years with lot of scope for crop improvement. It results in clonal progeny without fertilization, having maternal genetic constitution.

Seeds of doubt: Mendel’s choice of Hieracium to study inheritance, a case of right plant, wrong trait [PDF]

, 2016
KEY MESSAGE: In this review, we explore Gregor Mendel’s hybridization experiments with Hieracium , update current knowledge on apomictic reproduction and describe approaches now being used to develop true-breeding hybrid crops.

From a Phenotype to Transcriptomics Apomixis Initiation in the genus Boechera [PDF]

, 2009
The North American genus Boechera provides a highly polymorphic source of natural variation for studies on the regulation of apomictic development (asexual reproduction via seed).
