Toward in vitro fertilization in Brachiaria spp. [PDF]
, 2010 Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

The Male Gametophyte of Dacrydium [PDF]
Botanical Gazette, 1907 1. There are two prothallial cells cut off from the main body of the spore. In Dacrydium Bidwillii usually only the second divides; in D. laxifolium and D. cupressinum both divide. 2. The generative cell divides by an anticlinal wall, one daughter cell functioning as a body cell and the other being sterile. In some cases both produce body cells. 3. The

Cytoskeleton, EarlyView.ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Polyploid lineages in the genus Porphyra [PDF]
, 2018 Whole genome duplication is now accepted as an important evolutionary force, but the genetic factors and the life history implications affecting the existence and abundance of polyploid lineages within species are still poorly known.

Cytoskeleton, EarlyView.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 ...

Influence of water availability on gender determination of gametophytes in a diploid –polyploid complex of a xerophytic fern genus [PDF]
, 2015 Environmental sex determination (ESD) is present in several animal and plant lineages. Diverse factors such as temperature, light or water availability have been described as sex determinants in these organisms. Among plants, ferns frequently display ESD.

PLANTS, PEOPLE, PLANET, EarlyView.Iron deficiency anaemia remains a major public health challenge in Sub‐Saharan Africa, where population growth, displacement and limited resources heighten nutritional insecurity. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

The making of gametes in higher plants [PDF]
, 2005 Higher plants have evolved to be one of the predominant life forms on this planet. A great deal of this evolutionary success relies in a very short gametophytic phase which underlies the sexual reproduction cycle. Sexual plant reproduction takes place in

The evolution and patterning of male gametophyte development [PDF]
, 2019 The reproductive adaptations of land plants have played a key role in their terrestrial colonization and radiation. This encompasses mechanisms used for the production, dispersal and union of gametes to support sexual reproduction. The production of small motile male gametes and larger immotile female gametes (oogamy) in specialized multicellular ...
