Experience, and gynaecological and reproductive health follow-up of young adult women who have undergone ovarian tissue cryopreservation.

Research Question: What are the experience, and gynaecological and reproductive health outcomes in young adult women who have undergone ovarian tissue cryopreservation (OTC)?

Design: A retrospective observational study was conducted at a single institution between May 2019 and February 2021 including 87 women aged over 18 years undergoing OTC. Medical characteristics and questionnaire data collected more than 18 months after OTC were analysed.

Results: Close to 74% (n = 64/87) of women had a follow-up consultation and completed the questionnaire.

Twenty Years of Population Survey in France Suggests Pyramiding and in Rapeseed Is a Risky Resistance Management Strategy.

Strategies for plant resistance gene deployment aim to preserve their durability to highly adaptable fungal pathogens. While the pyramiding of resistance genes is often proposed as an effective way to increase their durability, molecular mechanisms by which the pathogen can overcome the resistance also are important aspects to take into account. Here, we report a counterexample where pyramiding of two resistance genes of , and , matching the avirulence genes and , respectively, favored the selection of double-virulent isolates.

Unusual evolutionary mechanisms to escape effector-triggered immunity in the fungal phytopathogen Leptosphaeria maculans.

Leptosphaeria maculans is the fungus responsible for the stem canker disease of oilseed rape (Brassica napus). AvrLm3 and AvrLm4-7, two avirulence effector genes of L. maculans, are involved in an unusual relationship: AvrLm4-7 suppresses the Rlm3-mediated resistance.

The dispensable chromosome of Leptosphaeria maculans shelters an effector gene conferring avirulence towards Brassica rapa.

Phytopathogenic fungi frequently contain dispensable chromosomes, some of which contribute to host range or pathogenicity. In Leptosphaeria maculans, the stem canker agent of oilseed rape (Brassica napus), the minichromosome was previously suggested to be dispensable, without evidence for any role in pathogenicity. Using genetic and genomic approaches, we investigated the inheritance and molecular determinant of an L.
