Microspore embryogenesis in barley: anther pre-treatment stimulates plant defence gene expression [PDF]
Microspore embryogenesis (ME) is a process in which the gametophytic pollen programme of the microspore is reorientated towards a new embryo sporophytic programme.

TRADITION, QUALITY AND BIOTECHNOLOGY IN HUNGARIAN SPICE PEPPER (Capsicum annuum L.) BREEDING [PDF]
Spice pepper production has a history of almost 300 years in the southern part of Hungary. In this study the results of two biotechnological improvements are summarized. Anther and isolated microspore culture techniques were improved to release haploid

Making Two out of One: Kinesin Motors Driving Plant Cell Division
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]
Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...

ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...
