APOK3, a pollen killer antidote in Arabidopsis thaliana

The paper identifies an antidote gene in Arabidopsis thaliana that counteracts a pollen killer allele, revealing its structure and evolutionary dynamics.

Genetics of Fertility Restoration in A1 Cytoplasmic Genetic Male Sterility (CGMS) Systems in Sorghum (Sorghum bicolor L. Moench)

This study investigates the genetics of fertility restoration in A1 cytoplasmic male sterility systems in sorghum, finding it is controlled by a single dominant gene in F2 and BC1 populations.

Standardization of cytological behavior of pollens in sorghum by Image analysis

The paper evaluates pollen fertility in sorghum hybrids using visual counting and image analysis, finding image analysis to be 95% efficient in detecting sterile vs. fertile pollen.

Integrated cyto-physiological and proteomic analyses reveal new insight into CMS mechanism in a novel upland cotton CMS line LD6A

The paper identifies molecular pathways and proteomic changes in a novel cotton CMS line LD6A, linking mitochondrial dysfunction to pollen sterility.

TaEXPB5 is responsible for male fertility in thermo-sensitive male-sterility wheat with Aegilops kotschyi cytoplasm

The paper identifies TaEXPB5 as a gene essential for male fertility in thermo-sensitive cytoplasmic male-sterility wheat, showing that its silencing leads to pollen abortion and fertility loss.

Changes in cell wall biochemistry affect the mechanical properties and growth rate of Arabidopsis pollen tubes

The paper combines experimental and simulation techniques to study how cell wall composition affects mechanical properties and growth rate in Arabidopsis pollen tubes.

GAMYB modulates bHLH142 and is homeostatically regulated by TDR during rice anther tapetal and pollen development

This study identifies GAMYB's role in modulating bHLH142 expression during rice pollen development and shows TDR's repressive effect on this regulation to maintain homeostasis.

Identification and genetic diversity analysis of a male-sterile gene (MS1) in Japanese cedar (Cryptomeria japonica D. Don)

The paper identifies a male-sterile gene (MS1) in Japanese cedar by analyzing deletions in a lipid transfer protein gene and proposes marker-assisted selection for breeding.

Identification of Cis-Regulatory Sequences Controlling Pollen-Specific Expression of Hydroxyproline-Rich Glycoprotein Genes in Arabidopsis thaliana

The paper identifies 15 cis-regulatory motifs controlling pollen-specific expression of HRGP genes in Arabidopsis thaliana using RNA-seq and promoter analysis.

Cytological abnormalities and pollen abortion in interspecific hybrids of Nicotiana

The paper investigates cytological abnormalities and pollen abortion in interspecific hybrids of Nicotiana, identifying membrane deficiencies and chromosome instability as key factors in sterility.

Gametophytes and embryo ontogeny: understanding the reproductive calendar of Cypripedium japonicum Thunb. (Cypripedoideae, Orchidaceae)

The paper studies the gametophyte development and reproductive biology of Cypripedium japonicum, creating a reproductive calendar based on light microscopy and SEM observations.

Arabidopsis ECERIFERUM3 (CER3) Plays a Critical Role in Maintaining Hydration for Pollen-Stigma Recognition during Fertilization

This study identifies CER3 as essential for tryphine lipid biosynthesis, which maintains pollen hydration during stigma recognition in Arabidopsis.

Synergid calcium ion oscillations define a new feature of pollen tube reception critical for blocking interspecific hybridization

The paper investigates calcium ion oscillations in synergid cells during pollen tube reception, identifying a critical role in blocking interspecific hybridization.

Self-Incompatibility Alleles in Iranian Pear Cultivars

The paper identifies S-alleles in Iranian pear cultivars using allele-specific PCR, finding common alleles and demonstrating the method's efficiency.

Base-pairing requirements for small RNA-mediated gene silencing of recessive self-incompatibility alleles in Arabidopsis halleri.

The paper investigates base-pairing requirements for small RNA-mediated gene silencing of recessive self-incompatibility alleles in Arabidopsis halleri using controlled crosses and RT-qPCR.

CrRLK1L receptor-like kinases HERCULES RECEPTOR KINASE 1 and ANJEA are female determinants of pollen tube reception

This study identifies HERK1 and ANJ as female determinants that redundantly promote pollen tube burst in synergid cells during plant fertilization.

Molecular Basis Underlying Male Sterility In bHLH142 Overexpressing Rice

This study shows that overexpressing bHLH142 in rice causes male sterility by triggering premature tapetal programmed cell death, providing a new method for hybrid seed production.

SLFL Genes Participate in the Ubiquitination and Degradation of S-RNase in Self-Compatible Chinese Peach

This study identifies three F-box genes, PperSLFL1-3, that ubiquitinate and degrade S-RNases in self-compatible peach, suggesting they function redundantly as S-RNase inhibitors.
