ABSTRACT The continuous increasing discharge of synthetic dyes into aquatic systems seems to be an important environmental and health risk due to their high toxicity and resistance to biodegradation. Among these dyes, methylene blue (MB) and Congo red (CR) are widely used in textile and industrial applications, necessitating sustainable and efficient ...

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 ...

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.

: During meiosis in flowering plants, degradation of the callose wall in tetrads releases newly produced microspores, which develop into mature pollen grains.

Early evolutionary history of the seed
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Gametic and somatic embryogenesis through in vitro anther culture of different Citrus genotypes [PDF]
: In vitro tissue culture represents a useful technique for advancing Citrus breeding and propagation. Among in vitro regeneration systems, anther culture is commonly used to produce haploids and doubled haploids for a fast-track producing homozygous ...

Microspore embryogenesis describes a stress-induced reprogramming of immature male plant gametophytes to develop into embryo-like structures, which can be regenerated into doubled haploid plants after whole genome reduplication. This mechanism is of high

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 ...

Bridging a biogeographic 'gap' : microfossil evidence for the quillwort Isoetes on the Cumberland Plain west of Sydney during the early Colonial period [PDF]
Fossil spores preserved on historical archaeological sites at Parramatta and Richmond indicate that two or more species of the quillwort genus Isoetes (family Isoetaceae) were growing along rivers on the Cumberland Plain, west of Sydney, during the late ...

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 ...
