The making of gametes in higher plants [PDF]
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

Abstract Wheat breeders are constantly looking for genes and alleles that increase grain yield. One key strategy is finding new genetic resources in the wild and domesticated gene pools of related species with genes affecting grain size. This study explored a natural population of Triticum turgidum (L.) phenotyped for grain weight and size‐related ...

The formation of cytomictic channels (CCs) during the tobacco microsporogenesis has been analyzed by microscopy and cytochemical methods. Starting from the pachytene stage, CCs were formed between microsporocytes with involvement of specific organelles ...

The transcription factors BEL1 and SPL are required for cytokinin and auxin signaling during ovule development in Arabidopsis [PDF]
Hormones, such as auxin and cytokinin, are involved in the complex molecular network that regulates the coordinated development of plant organs. Genes controlling ovule patterning have been identified and studied in detail; however, the roles of auxin ...

Patterns and Drivers of Pollen Temperature Tolerance
ABSTRACT Pollen, a pivotal stage in the plant reproductive cycle, is highly sensitive to temperature fluctuations, impacting seed quality and quantity. While the importance of understanding pollen temperature limits (Tmin, Topt, Tmax – collectively PTLs) is recognized, a comprehensive synthesis of underlying drivers is lacking.

Chemical mutagenesis in head cabbage (Brassica oleracea var.capitata L.): III effect of ethyl methane sulphonate on mycosporogenesis and pollen fertility [PDF]
The aim of present investigation was to study the effect of different ethyl methane sulfonate (EMS) concentrations (0.5, 0.6 and 0.7%) on microsporogenesis and on the expression of pollen fertility in M1 plants, obtained from treated cabbage seeds ...

Marker-free transgenic plants through genetically programmed auto-excision [PDF]
We present here a vector system to obtain homozygous marker-free transgenic plants without the need of extra handling and within the same time frame as compared to transformation methods in which the marker is not removed.

Microsporogenesis and pollen formation in cassava
This article describes the complete microsporogenesis and pollen formation in cassava (Manihot esculenta Crantz) at the various developmental stages (pollen mother cell, meiosis, tetrads, early free spore, mid uninucleate, late uninucleate, binucleate and mature pollen grain).

Temperatures in the Brazilian Cerrado—an important, complex, and biodiverse savannah ecosystem–are increasing, potentially impacting many aspects of plant development and function, including sexual reproduction, which is thought to be particularly sensitive to temperature stress.
