Microsporogenesis and the biosynthesis of floral small interfering RNAs in coffee have a unique pattern among eudicots, suggesting a sensitivity to climate changes

Plant Direct
Recently, the siRNAs pathways, and especially reproductive phasiRNAs, have attracted attention in eudicots since their biological roles are still unknown and their biogenesis took different evolutionary pathways compared to monocots.

Methodologies and Considerations in Evaluating Heat Stress Response and Thermotolerance of Pollen Grains. [PDF]

Physiol Plant
ABSTRACT Elevated temperatures severely disrupt pollen function, posing a major threat to agricultural productivity. While research into pollen thermotolerance is rapidly expanding, the quest to identify and develop heat‐tolerant crops is challenged by a lack of consistent methodological considerations and experimental design principles.

Comparative insights into molecular pathways influencing germline development in early-divergent angiosperms. [PDF]

Plant J
SUMMARY The molecular and genetic mechanisms regulating female germline development remain largely unknown in basal and early‐divergent angiosperms. This contrasts with recent progress in model eudicots such as Arabidopsis thaliana and monocots, such as rice, barley, and maize. In this study, we investigate the genetic pathway governing female germline

Editing of ORF138 restores fertility of Ogura cytoplasmic male sterile broccoli via mitoTALENs. [PDF]

Plant Biotechnol J
Summary Cytoplasmic male sterility (CMS), encoded by the mitochondrial open reading frames (ORFs), has long been used to economically produce crop hybrids. However, the utilization of CMS also hinders the exploitation of sterility and fertility variation in the absence of a restorer line, which in turn narrows the genetic background and reduces ...

The carnivorous rainbow plant Byblis filifolia Planch. secretes digestive enzymes in response to prey capture independently of jasmonates. [PDF]

Plant Biol (Stuttg)
Secretion of digestive enzymes in response to prey capture in carnivorous plants with sticky traps is regulated by jasmonates in Drosera capensis but differently by unknown factor in Byblis filifolia. Abstract Carnivorous plants from the order Caryophyllales co‐opted plant phytohormones from a group of jasmonates to regulate digestive enzyme activity ...

Disturbances in microsporogenesis and pollen grain development in Gagea lutea (L.) Ker. Gaw.

Acta Agrobotanica, 2012
The meiotic division of microsporocytes and pollen grain development in Gagea lutea (L.) Ker.-Gaw. (Liliaceae) with fluorescence microscope (excitation light 400 nm) was observed after squashing the anthers in DAPI solution (fluorochrom dying DNA). Up to

Microsporogenesis of Apricot Cultivars in Hungary

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2013
Like all phenological processes, microsporogenesis is mainly determined genetically, but its phenotypical expression is greatly influenced by environmental factors, particularly the temperature.

Variations of total protein content and protein synthesis during microsporogenesis in Larix europaea L.

Acta Societatis Botanicorum Poloniae, 2014
The variations of the total protein content and protein synthesis were analyzed in successive stages of microsporogenesis in Larix europaea L. Pure fractions of microsporocytes containing the cells in successive phases of meiosis and fractions of the ...

Cytogenetic studies in the Eragrostis curvula Complex

Bothalia: African Biodiversity & Conservation, 1977
Cytogenetic studies were undertaken in the  Eragrostis curvula Complex. Three plants were studied at each of 16 collecting points. The overall morphology and embryo sac development of all plants were evaluated, while the chromosome number and ...
