Callose (β-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth [PDF]

, 2005
Background: Callose (β-1,3 glucan) separates developing pollen grains, preventing their underlying walls (exine) from fusing. The pollen tubes that transport sperm to female gametes also contain callose, both in their walls as well as in the plugs that ...

Phosphatidic acid counteracts S-RNase signaling in pollen by stabilizing the actin cytoskeleton [PDF]

, 2018
S-RNase is the female determinant of self-incompatibility (SI) in pear (Pyrus bretschneideri). After translocation to the pollen tube, S-RNase degrades rRNA and induces pollen tube death in an S-haplotype-specific manner. In this study, we found that the

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

New 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.

Pollination biology of Impatiens cuspidate Wight and Arn. (Balsaminaceae), a rare and endemic balsam of the Western Ghats, India

Journal of Threatened Taxa, 2011
The pollination biology of Impatiens cuspidata, a rare and endemic balsam from the Western Ghats, has been studied with special reference to phenology, pollination, pollen-pistil interactions, breeding experiments and stigma receptivity.

Gene coexpression analysis reveals key pathways and hub genes related to late-acting self-incompatibility in Camellia oleifera

Frontiers in Plant Science, 2023
IntroductionSelf-incompatibility (SI) is an important strategy for plants to maintain abundant variation to enhance their adaptability to the environment.

Thiol-based redox regulation in sexual plant reproduction: new insights and perspectives [PDF]

, 2013
The success of sexual reproduction in plants involves (i) the proper formation of the plant gametophytes (pollen and embryo sac) containing the gametes, (ii) the accomplishment of specific interactions between pollen grains and the stigma, which ...

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

Plant 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.

A species-specific cluster of defensin-like genes encodes diffusible pollen tube attractants in Arabidopsis.

PLoS Biology, 2012
Genes directly involved in male/female and host/parasite interactions are believed to be under positive selection. The flowering plant Arabidopsis thaliana has more than 300 defensin-like (DEFL) genes, which are likely to be involved in both natural ...

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

Plant 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.
