Background: Tapping panel dryness (TPD) in rubber tree has become the most severe restricting factor of natural rubber production. To date, there is no effective measures to prevent and control TPD. Previous studies primarily focused on analyzing the molecular mechanism underlying TPD occurrence.

This study aims to develop an interpretable machine learning (ML) model to accurately predict the probability of achieving total pathological complete response (tpCR) in patients with locally advanced breast cancer (LABC) following neoadjuvant chemotherapy (NAC). This multi-center retrospective study included pre-NAC clinical pathology data from 698 LABC patients. Post-operative pathological outcomes divided patients into tpCR and non-tpCR groups.

The majority of the world's natural rubber comes from the rubber tree (). As a key enzyme for synthesizing phenylpropanoid compounds, phenylalanine ammonia-lyase (PAL) has a critical role in plant satisfactory growth and environmental adaptation. To clarify the characteristics of rubber tree PAL family genes, a genome-wide characterization of rubber tree was conducted in this study.

Currently, one of the most serious threats to rubber tree is the tapping panel dryness (TPD) that greatly restricts natural rubber production. Over-tapping or excessive ethephon stimulation is regarded as the main cause of TPD occurrence. Although extensive studies have been carried out, the molecular mechanism underlying TPD remains puzzled.

Article Synopsis
  • Tapping panel dryness (TPD) significantly decreases latex yield in rubber trees, and its molecular causes remain largely unknown.
  • This study utilized whole-transcriptome sequencing to identify over 40,000 RNA molecules in latex from both TPD-affected and healthy rubber trees, finding many differentially expressed RNAs linked to TPD.
  • Key regulatory pathways involved in TPD include plant hormone signaling and MAPK signaling, with hormone levels significantly altered, indicating disruption in hormone balance in TPD trees and suggesting a complex RNA network that may drive TPD onset.
