Article Synopsis
  • - Retained fetal membranes (RFM) in dairy cows is a reproductive condition related to the adhesion of placenta tissue, significantly involving collagen type IV (COL-IV) breakdown, crucial for placental expulsion.
  • - The study aimed to explore the role of the focal adhesion kinase (FAK) signaling pathway in regulating COL-IV, with tissue samples collected from healthy cows and those with RFM for comparison.
  • - Results showed that in RFM cows, levels of key FAK pathway proteins (FAK, Src, MMP-2, and MMP-9) were lower while COL-IV levels were higher, indicating a potential pathway disruption related to RFM that could influence future treatment strategies.

Adzuki bean, an important legume crop, exhibits poor tolerance to low temperatures. To investigate the effect of exogenous abscisic acid (ABA) on the physiological metabolism and yield resistance of adzuki bean under low-temperature stress, we conducted a potted experiment using Longxiaodou 4 (LXD 4) and Tianjinhong (TJH) as test materials and pre-sprayed with exogenous ABA at flowering stage continuously for 5 days with an average of 12°C and an average of 15°C, respectively. We found that, compared with spraying water, foliar spraying exogenous ABA increased the activities of antioxidants and the content of non-enzymatic antioxidants, effectively inhibited the increase of malondialdehyde (MDA), hydrogen peroxide (H2O2) content, O2-· production rate.

  • Low temperatures negatively impact global agricultural productivity, necessitating adaptations and mitigation strategies to manage this stress.
  • The study found that the plant growth regulator Uniconazole (S3307) helps reduce oxidative damage in mung bean leaves by increasing antioxidant enzyme activities and reducing harmful reactive oxygen species and malonaldehyde levels.
  • Foliar application of S3307 improved the yield of mung beans under cold conditions by 5.1%-12.5% and 6.3%-32.9%, suggesting it enhances plant tolerance to low temperatures and reduces yield loss.

Introduction: Low light stress inhibits plant growth due to a line of physiological disruptions in plants, and is one of the major barriers to protected cucumber cultivation in northern China.

Methods: To comprehensively understand the responses of cucumber seedlings to low-light stress, the low-light-tolerant line (M67) and The low-light-sensitive line (M14) were conducted for the analysis of photosynthetic phenotype, RNA sequencing (RNA-seq) and the expression level of photosynthesis-related genes in leaves under low-light stress and normal light condition (control).

Results: The results showed that there was a sharp decrease in the photosynthate accumulation in the leaves of the sensitive line, M14, resulting in a large decrease in the photosynthetic rate (Pn) (with 31.
