From recognition to response: integrated signaling pathways determining pollen acceptance and rejection in Brassicaceae

open access: yesNew Phytologist, EarlyView.
Summary Generation of competent offspring is vital for the prosperity of flowering plants. The pistil not only functions as a conduit for pollen tubes to grow to the ovary but also provides a selective venue for facilitating the growth of compatible pollen tubes and discouraging invaders and incompatible pollen.

Fertilization in Flowering Plants 2. Selection of the Male Partner is the Prerogative of the Maternal Parent [PDF]

open access: yes, 2016
After the pollen grain reaches the stigma through outsourced agents (pollinators), the next step before fertilization is to select the right type of pollen.

In perennial Arabis alpina, CONSTANS and FLOWERING LOCUS T have common and distinct effects on flowering and inflorescence architecture

open access: yesNew Phytologist, EarlyView.
Summary Flowering of perennial Arabis alpina is differentially regulated on primary and axillary shoots. Although contributions of vernalization and ageing pathways have been analysed, those of photoperiodic flowering genes CONSTANS (CO), FLOWERING LOCUS T (FT), and TWIN‐SISTER OF FT (TSF) remain unexplored.

Polyamines in pollen: from microsporogenesis to fertilization

open access: yesFrontiers in Plant Science, 2016
The entire pollen life span is driven by polyamine (PA) homeostasis, achieved through fine regulation of their biosynthesis, oxidation, conjugation, compartmentalization, uptake, and release.

MsWRKY49 Modulates Pollen Tube Elongation in Response to Boron Deficiency by Regulating Reactive Oxygen Species Homeostasis in Alfalfa

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Boron, an essential micronutrient, plays a crucial role in plant reproductive processes. Boron deficiency is widespread in many regions and significantly reduces alfalfa (Medicago sativa) seed yield, yet the molecular mechanisms underlying its impact on reproductive organ development remain elusive.

Finding new Arabidopsis receptor kinases that regulate compatible pollen-pistil interactions

open access: yesFrontiers in Plant Science, 2022
Successful fertilization of a flowering plant requires tightly controlled cell-to-cell communication between the male pollen grain and the female pistil. Throughout Arabidopsis pollen-pistil interactions, ligand-receptor kinase signaling is utilized to mediate various checkpoints to promote compatible interactions.

Metabolic control of tobacco pollination by sugars and invertases [PDF]

open access: yes, 2017
Pollination in flowering plants is initiated by germination of pollen grains on stigmas followed by fast growth of pollen tubes representing highly energy-consuming processes.

Divergent Mating Systems and Parental Conflict as a Barrier to Hybridization in Flowering Plants [PDF]

open access: yes, 2005
Parental conflicts can lead to antagonistic coevolution of the sexes and of parental genomes. Within a population, the resulting antagonistic effects should balance, but crosses between populations can reveal conflict.

Trans‐QTL Alliance of HKT1 and PHL7 Modulate Salinity Stress Tolerance and Enhance Crop Yield Endurance

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Salinity stress can cause significant yield losses in crops because of its major impact on reproductive success. The complexity of salinity stress responses, particularly their tissue‐ and cell‐specific regulation, continues to challenge the translation of molecular insights into tangible crop yield improvements.
