Development of a Synthetic Floral Lure for Pollen Beetles (Coleoptera: Nitidulidae) [PDF]

, 2022
Pollen beetles (Coleoptera: Nitidulidae) rank among the most important pests of oilseed rape (Brassica napus). For their timely detection in early spring, yellow sticky or water pan traps are used; however, it has been suggested that the addition of ...

Transcript Profiling Analysis and ncRNAs’ Identification of Male-Sterile Systems of Brassica campestris Reveal New Insights Into the Mechanism Underlying Anther and Pollen Development

Frontiers in Plant Science, 2022
Male-sterile mutants are useful materials to study the anther and pollen development. Here, whole transcriptome sequencing was performed for inflorescences in three sterile lines of Chinese cabbage (Brassica campestris L. ssp. chinensis Makino, syn.

Annexin5 Is Essential for Pollen Development in Arabidopsis [PDF]

Molecular Plant, 2014
Pollen development is a post-meiotic process that produces mature pollen grains from microspores and can be regarded as an ideal model for the study of important plant physiological processes such as reproduction, cellular differentiation, cell fate determination, signal transduction, membrane transport, and fusion and polar growth.

Perspectives on deciphering mechanisms underlying plant heat stress response and thermotolerance

, 2013
Global warming is a major threat for agriculture and food safety and in many cases the negative effects are already apparent. The current challenge of basic and applied plant science is to decipher the molecular mechanisms of heat stress response (HSR ...

Pollen grain of barley (Hordeum vulgare L.) - pattern of development

Acta Societatis Botanicorum Poloniae, 2014
Pollen development in barley follows the general pattern established for other species of Poaceae: 1) microspore division occurs at the vacuolate microspore stage with polarly located nucleus; 2) microspore mitosis is immediately followed by phragmoplast

RNA-seq analysis of synchronized developing pollen isolated from a single anther

Frontiers in Plant Science, 2023
Pollen development, from unicellular microspores to anthesis, is a complex process involving the coordinated specification, differentiation and functions of different cell types. Key to understanding this development is identifying the genes expressed at

Ensuring Reproduction at High Temperatures: The Heat Stress Response during Anther and Pollen Development

Plants, 2013
Sexual reproduction in flowering plants is very sensitive to environmental stresses, particularly to thermal insults which frequently occur when plants grow in field conditions in the warm season.

Pollen development of Rondeletia odorata (Rubiaceae) [PDF]

American Journal of Botany, 2001
Pollen wall ontogeny of Rondeletia odorata was studied with transmission electron microscopy (TEM) and scanning electron microscopy (SEM) from tetrad stage until maturity. The ontogenetic sequence of wall development in Rondeletia follows, to some extent, the basic scheme in the angiosperms, i.e., development starts centripetally with the pro ...

Do pollen beetles need pollen? The effect of pollen on oviposition, survival and development of a flower-feeding herbivore

, 2004
1. Pollen is considered to be an important dietary component for many species of flower-feeding herbivores. Its influence on oviposition site selection by the pollen beetle Meligethes aeneus, and on the development of its larvae was investigated. 2.

Tightly Controlled Expression of bHLH142 Is Essential for Timely Tapetal Programmed Cell Death and Pollen Development in Rice

Frontiers in Plant Science, 2017
Male sterility is important for hybrid seed production. Pollen development is regulated by a complex network. We previously showed that knockout of bHLH142 in rice (Oryza sativa) causes pollen sterility by interrupting tapetal programmed cell death (PCD)
