The tapetal tissue is essential for the maintenance of redox homeostasis during microgametogenesis in tomato [PDF]

open access: yesThe Plant Journal, Volume 112, Issue 5, Page 1281-1297, December 2022., 2022
Significance Statement During anther development, the tapetal cells that surround the sporocytes have essential roles in male meiotic progression and the formation of mature pollen grains. In tomato, despite its importance for breeding purposes, the interaction between the tapetum and sporogenous tissues is poorly understood.

Microsporogenesis, microgametogenesis, and pollen grain morphology of Fouquieria fasciculata (Fouquieriaceae, Ericales)

open access: yesBotan‪ical Sciences, 2023
Background: Embryology of the male reproductive structures in Fouquieriaceae has been poorly studied. The ontogeny of the anther wall, microsporogenesis, microgametogenesis, and pollen morphology were described in detail for Fouquieria fasciculata ...

Structure of staminate flowers, microsporogenesis, and microgametogenesis in Helosis cayennensis var. cayennensis (Balanophoraceae) [PDF]

open access: yesAnales del Jardín Botánico de Madrid, 2013
We analyzed the microgametogenesis and microsporogenesis of the male flowers of the holoparasitic Helosis cayennensis (Sw.) Spreng. var. cayennensis using optical and scanning electron microscopy.

Microsporogenesis and microgametogenesis of Excentrodendron hsienmu (Malvaceae s.l.) and their systematic implications [PDF]

open access: yesBotanical Journal of the Linnean Society, 2006
Flowers, microsporogenesis and microgametogenesis of Excentrodendron hsienmu in opening-functional flowers and non-opening flowers were studied to investigate the evolutionary relationships of Excentrodendron. E. hsienmu is a dioecious species that blossoms every 3-4 years, although large numbers of flower buds develop every year.

Comparative transcriptome analysis reveals key insights into male sterility in Salvia miltiorrhiza Bunge [PDF]

open access: yesPeerJ, 2021
Background Large-scale heterosis breeding depends upon stable, inherited male sterility lines. We accidentally discovered a male sterility line (SW-S) in the F1progeny of a Salvia miltiorrhiza Bunge from Shandong, China (purple flowers) crossed with a S.

A multistage Plasmodium CRL4WIG1 ubiquitin ligase is critical for the formation of functional microtubule organization centers in microgametocytes [PDF]

open access: yesmBio
Malaria is a mosquito-borne infectious disease caused by unicellular eukaryotic parasites of the Plasmodium genus. Protein ubiquitination by E3 ligases is a critical post-translational modification required for various cellular processes during the ...

Microsporogenesis and microgametogenesis of Cardiospermum grandiflorum and Urvillea chacoensis (Sapindaceae, Paullinieae)

open access: yesAustralian Journal of Botany, 2010
Microsporogenesis and microgametogenesis of two species, Cardiospermum grandiflorum Sw. and Urvillea chacoensis Hunz. (Sapindaceae, Paullinieae), were studied using light and transmission electron microscopy. Both species are monoecious, with staminate and hermaphrodite, although functionally pistillate, flowers.

THE USE OF MALE STERILITY OF OGURA TYPE IN RADISH BREEDING FOR HETEROSIS

open access: yesОвощи России, 2011
The morphological marker characteristics of the flower and cytological features of microgametogenesis and microsporo-genesis in sterile plants have been studied to identify and select plants bearing Ogura male sterility type.

Microgametophyte Development in Cannabis sativa L. and First Androgenesis Induction Through Microspore Embryogenesis

open access: yesFrontiers in Plant Science, 2021
Development of double haploids is an elusive current breeding objective in Cannabis sativa L. We have studied the whole process of anther and pollen grain formation during meiosis, microsporogenesis, and microgametogenesis and correlated the different ...

The effects of heat stress on male reproduction and tillering in Sorghum bicolor

open access: yesFood and Energy Security, Volume 12, Issue 6, November 2023., 2023
Abstract Due to global climate change, heat stress is increasingly harming the growth, development, overall biomass, and grain yield of numerous crops. Heat stress impairs pollen development and thus reduces seed set in Sorghum bicolor (L.) Moench; however, the effects of heat stress on anther development at specific stages and tiller formation remain ...
