Cryoimmobilized anther analysis reveals new ultrastructural insights into Rhynchospora (Cyperaceae) asymmetrical microsporogenesis [PDF]
Frontiers in Plant ScienceIntroductionThe Cyperaceae family is distinguished by holocentric chromosomes and a distinctive microsporogenesis process, which includes inverted meiosis, asymmetric tetrad formation, selective cell death, and the formation of pseudomonad pollen ...

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

Using a wheat line with wild emmer genetic material to improve modern Triticum aestivum L. varieties by a complex of economically useful traits [PDF]
Вавиловский журнал генетики и селекцииWild emmer Triticum dicoccoides samples have a high content of protein and microelements in their grain, but when crossed with common wheat varieties, undesirable properties of a wild relative (low yield, spike fragility and difficult threshing) can be ...

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

Evaluation of mitotic activity in tapetal cells of grapevine (Vitis L.)
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2021 The knowledge with reference to the grapevine tapetum has been centered on its anatomy/morphology and hardly anything at all is known about its mitotic activity throughout the microsporogenesis. The aim of this study was to ascertain the mitotic activity

Evaluation of the course of microsporogenesis in some selected peach (Prunus persica L./Batsch) cultivars [PDF]
Acta Agriculturae Serbica, 2014 The evaluation of the microsporogenesis process was performed from January to April within the period of 2011-2013. The experiment involved 15 peach cultivars and the control cultivar Redhaven. The course of microsporogenesis was evaluated on the base of

Flower bud development of almond cultivars based on three different methods
Folia Horticulturae, 2023 Flower bud development of fruit trees plays a key role in their climatic adaptation. It is closely related to dormancy release that determines winter frost susceptibility. Detailed characterisation of flower bud development of 25 almond (Prunus amygdalus
