FIGL1 prevents aberrant chromosome associations and fragmentation and limits crossovers in polyploid wheat meiosis

New Phytologist, Volume 244, Issue 2, Page 528-541, October 2024.
Summary Meiotic crossovers (COs) generate genetic diversity and are crucial for viable gamete production. Plant COs are typically limited to 1–3 per chromosome pair, constraining the development of improved varieties, which in wheat is exacerbated by an extreme distal localisation bias.

The transcription factor LBD10 sustains pollen tube growth and integrity by modulating reactive oxygen species homeostasis via the regulation of flavonol biosynthesis in Arabidopsis

New Phytologist, Volume 244, Issue 1, Page 131-146, October 2024.
Summary Reproduction in angiosperms relies on the precise growth of pollen tubes, facilitating the delivery of sperm cells to the ovule for double fertilization. LATERAL ORGAN BOUNDARIES DOMAIN10 (LBD10), a plant‐specific transcription factor, plays a pivotal role in Arabidopsis pollen development.

MULTIPLICACIÓN In vitro DE Nephrolepis exaltata (L.) Schott, A PARTIR DE ESPORAS

Revista Chapingo Serie Horticultura, 2006
El presente trabajo tiene como objetivo establecer los requerimientos hormonales y nutrimentales para inducir la germinación de esporas de Nephrolepis exaltata (L.) Schott in vitro, así como para la obtención de plántulas. En la fase de germinación, la desinfección de los soros fue efectiva en 96 %, con 100 % de supervivencia del inóculo.

VARIACIÓN ESTACIONAL DE LAS ASCOSPORAS DE Helicogermslita (XYLARIACEAE) EN LA ATMÓSFERA DE BAHÍA BLANCA, ARGENTINA.

Polibotánica, 2020
Helicogermslita (Xylariaceae, Ascomycota) se caracteriza por poseer ascosporas cuyo carácter distintivo es su surco germinativo en forma de ranura helicoidal que va de un extremo a otro con dos o más giros visibles en la superficie.

Unravelling the unusual: chromosome elimination, nondisjunction and extra pollen mitosis characterize the B chromosome in wild sorghum

New Phytologist, Volume 243, Issue 5, Page 1840-1854, September 2024.
Summary The B chromosomes exhibit diverse behaviour compared with conventional genetic models. The capacity of the B chromosome either to accumulate or to be eliminated in a tissue‐specific manner is dependent on biological processes related to aberrant cell division(s), but here yet remains compatible with normal development.

Impact of protein domains on the MEL2 granule, a cytoplasmic ribonucleoprotein complex maintaining faithful meiosis progression in rice

New Phytologist, Volume 243, Issue 6, Page 2235-2250, September 2024.
Summary Cytoplasmic ribonucleoprotein (RNP) granules are membraneless structures composed of various RNAs and proteins that play important roles in post‐transcriptional regulation. While RNP granules are known to regulate the meiotic entry in some organisms, little is known about their roles in plants.

A promoter polymorphism defines distinct roles in anther development for Col‐0 and Ler‐0 alleles of Arabidopsis ACYL‐COA BINDING PROTEIN3

New Phytologist, Volume 243, Issue 4, Page 1424-1439, August 2024.
Summary Acyl‐CoA‐Binding Proteins (ACBPs) bind acyl‐CoA esters and function in lipid metabolism. Although acbp3‐1, the ACBP3 mutant in Arabidopsis thaliana ecotype Col‐0, displays normal floral development, the acbp3‐2 mutant from ecotype Ler‐0 characterized herein exhibits defective adaxial anther lobes and improper sporocyte formation.

Sequential breakdown of the Cf‐9 leaf mould resistance locus in tomato by Fulvia fulva

New Phytologist, Volume 243, Issue 4, Page 1522-1538, August 2024.
Summary Leaf mould, caused by Fulvia fulva, is a devastating disease of tomato plants. In many commercial tomato cultivars, resistance to this disease is governed by the Cf‐9 locus, which encodes five paralogous receptor‐like proteins. Two of these proteins confer resistance: Cf‐9C recognises the previously identified F.
