Phaseolus vulgaris line A193 has been shown to be widely resistant to Colletotrichum lindemuthianum, including race 1472, one of the most virulent races of C. lindemuthianum characterized. Resistance to C. lindemuthianum race 1472 in P. vulgaris line A193 was investigated in segregating F and F populations from a cross between A193 and Flor de Mayo Bajio (a commercial cultivar highly susceptible to C. lindemuthianum). Resistance to 1472 in A193 was determined to be conditioned by a single dominant gene. Inoculation of crosses between A193 and cultivars Michigan Dark Red Kidney and Perry Marrow with race 1472 suggest that resistance in A193 is conditioned by the Co-1 gene. Inoculation of the cross A193 × Perry Marrow with C. lindemuthianum race 2, demonstrated that resistance to race 2 in Perry Marrow is also conditioned by a single dominant gene and is distinct to resistance in A193 or Michigan Dark Red Kidney. Three AFLP markers (ECAG/MACC-1, EACA/MAGA-2, EAGG/MAAC-8) linked in repulsion to the Co-1 locus were identified by screening the A193 × Flor de Mayo F population with 314 random amplified polymorphic DNA, amplified fragment length polymorphism, and restriction fragment length polymorphism markers. The two most closely linked markers should be useful in marker-assisted selection for Co-1.

Background: The role of LNX1 antisense RNA 2 (LNX1-AS2) in lung adenocarcinoma (LUAD) remains unclear.
Objective: This study aimed to investigate the association between LNX1-AS2 and LUAD by employing bioinformatics analysis and experimental validation.
Methods: Statistical analysis and database interrogation were utilized to assess correlations among LNX1-AS2 expression, clinical characteristics of LUAD patients, prognostic factors, regulatory networks, and immune infiltration.

The early evolution of sex chromosomes has remained obscure for more than a century. The Vandiemenella viatica species group of morabine grasshoppers is highly suited for studying the early stages of sex chromosome divergence and degeneration of the Y chromosome. This stems from the fact that neo-XY sex chromosomes have independently evolved multiple times by X-autosome fusions with different autosomes.

Contrary to expectations about solidarity and sisterhood between women, women managers sometimes distance themselves from junior women in the workplace when facing identity threat, that is, the feeling that one's social identity-such as race or gender-is devalued or undermined. For example, women managers might distance themselves from lower status junior women by seeing themselves as more masculine and career committed than their junior women colleagues. To advance our understanding of how to combat self-group distancing, the present research proposed and tested whether taking the perspective of junior women would attenuate these ingroup-distancing tendencies in women managers.

Morabine grasshoppers in the Vandiemenella viatica species group, which show karyotype diversity, have been studied for their ecological distribution and speciation in relation to their genetic and chromosomal diversity. They are good models for studying sex chromosome evolution as "old" and newly emerged sex chromosomes co-exist within the group. Here we present a reference genome for the viatica19 chromosomal race, that possesses the ancestral karyotype within the group.

Article Synopsis
- In 2012, the USPSTF classified PSA screening for prostate cancer as "category D," leading to a study on the effects of this change on metastatic prostate cancer (mPCa) diagnoses among different racial, ethnic, and socioeconomic groups.
- The study used data from 2004 to 2017 and found that post-recommendation, there was an increase in mPCa cases at diagnosis, especially among Hispanics and non-Hispanic Blacks.
- Factors like insurance status and household income significantly influenced the likelihood of presenting with mPCa, with uninsured minorities facing higher risks and low-income non-Hispanic Blacks showing increased rates of diagnosis.
