Papain-like cysteine proteases (PLCPs) are a large class of proteolytic enzymes involved in plant growth and development as well as plant responses to biological and abiotic stresses. However, there is no detailed characterization of PLCPs genes in poplar. In this study, a genome-wide analysis of the poplar PtrPLCPs family revealed 47 PtrPLCPs, which were classified into nine subfamilies according to their phylogeny: RD21, CEP, XCP, XBCP3, SAG12, RD19 (5), ALP, CTB, and the lost THI subgroups.

Isoprene serves an important part in plant defense against biotic and abiotic stresses, while also exerting a crucial influence on atmospheric photochemical processes and global climate change. The regional climate-chemistry-ecosystem model (RegCM-Chem-YIBs) was employed in the following study to estimate the biogenic isoprene emissions (BISP) in China during 2018-2020. The model explored the relative contributions of various stress factors such as drought, carbon dioxide (CO), and surface ozone (O) to isoprene emissions.

Winter wheat is the most dominant crop in Oklahoma and critically important to the economy of agricultural industry in this state and the region. However, weather anomalies such as droughts, which are frequent in Oklahoma, pose serious threats to winter wheat yield. This study was conducted to assess the effects of droughts on the simulated yield of dryland winter wheat (Y) in Oklahoma employing a gridded approach with the AquaCrop Open Source (AquaCrop-OS).

Article Synopsis
- Drought in China has worsened recently, with 78.4% of the country experiencing increasing drought severity, particularly since 2000.
- The analysis identified precipitation and temperature as the main factors influencing drought, accounting for 45.7% and 30.8% impact on drought trends across China, respectively.
- The study concludes that warmer temperatures are significantly driving drought changes, highlighting regional differences in how various factors contribute to drought conditions.

In 2023, the CO growth rate was 3.37 ± 0.11 ppm at Mauna Loa, which was 86% above that of the previous year and hit a record high since observations began in 1958, while global fossil fuel CO emissions only increased by 0.
