Pachytene Analyses in Some Genera of Minor Millets

Abstract

Analyses of pachytene karyotype were conducted in 18 different accessions of Eleusine indica (L.) Gaertn., Panicum antidotale Retz. and Setaria italica (L.) Beauv. However, these accessions showed the presence of chromomeric patterns at or around the centromeric regions. The pachytene chromosome complements of different accessions of these genera differed in the length of the long arm, short arm, and total chromomeres of their constituent chromosomes. The accessions exhibited significant variability in their pachytene chromosome characteristics.

History and New Developments on the 90th Anniversary of Cytologia: On the Occasion of the Publication of “Dawn of Modern Wheat Genetics”

“…Several reports on Poaceae have been published in Cytologia over the past 2 years (Gupta, et al 2018, Khah and Verma 2017, Rani et al 2017, Kaur and Gupta 2018, Özer et al 2018, Shiogai et al 2018. A useful review on the wheat genome was published by Tsunewaki in 2018, and the expression profiles of two long noncoding RNAs in salt-stressed barley roots were detailed by Karlik et al (2018) in the same year.…”

“…The generation of mutants of this important cereal crop using physical or chemical mutagens is important for genetic studies and plant breeding programs. Rani et al (2017) performed pachytene analyses of 18 accessions of three genera of minor millet: Eleusine indica, Panicum antidotale, and Setaria italica.…”

Seasonal and Diurnal Regulation of Flowering <i>via</i> an Epigenetic Mechanism in <i>Arabidopsis thaliana</i>

“…Because plants are sessile organisms, they must be able to adapt to fluctuating environmental conditions to survive. Flowering, which is one of the most sophisticated survival mechanisms that evolved in plants, involves meiosis, which can increase the genetic diversity of progeny through recombination due to the pairing of homologous chromosomes (Gupta et al 2017a, b, 2018a, b, Jeelani et al 2017, Kumar et al 2017, Liébana et al 2017, Rani et al 2017, Saggoo and Kaur 2017, Singhal and Kumari 2017, b, Dhaliwal et al 2018a, b, Farooq and Saggoo 2018, b, Kumari and Singhal 2018. Genetic diversity has resulted in the development of various phenotypes depending on environmental factors, and is one of the driving forces responsible for increases in the geographical distribution of certain plant species (Bordbar et al 2017, Shaker et al 2017, Shibata et al 2017, Muakrong et al 2018, Özer et al 2018, Senavongse et al 2018, Tapia-Pastrana et al 2018.…”
