针对植物工厂对番茄采摘作业的智能化需求,为克服在采摘作业过程中因番茄果实大小不一、遮挡重叠造成的识别精度不高和速度不快的问题,提出了YOLOX-L的改进型目标识别模型YOLOX-L-TN。该模型依据特征图的通道和空间注意力机制的内部结构和原理,设计了含有残差结构的TN模块,并融入到YOLOX-L的主干网络中,在保持网络轻量化的同时,实现模型识别速度和精度的同时提升。与YOLOX-L相比,YOLOXL-TN的AP值提高了4.81个百分点,单张图像的识别时间提升了0.141 7 s,TN模块的最佳位置为输入端与主干网络之间。进一步将TN模块与类似模块SENet、CAM、CBAM和CAM进行对比,AP值分别提高0.53、4.19、6.12、6.34个百分点,单张图像识别时间分别提升0.019 1、0.025 0、0.021 1、0.018 9 s。由此可见,提出的YOLOX-L-TN模型具有精度高、识别速度快、鲁棒性高等优点,可为番茄后期的智能采摘提供技术支持。

Plant nucleotide-binding, leucine-rich repeat receptors(NLRs) perceive pathogen avirulence effectors and activate defense ***-binding, leucine-rich repeat receptors are classified into coiled-coil(CC)-containing and Toll/interleukin-1 receptor(TIR)-containing NLRs. Recent advances suggest that NLR CC domains often function in signaling activation, especially for induction of cell death. In this review, we outline our current understanding of NLR CC domains, including their diversity/classification and structure, their roles in cell death induction, disease resistance, and interaction with other proteins. Furthermore, we provide possible directions for future work.

Geminivirus is a kind of single-stranded DNA virus. Experimental results from tomato golden mosaic virus (TGMV) showed that expression pattern of coat protein gene (cp) promoter was phloem specifically expressed. In this note, the studies on cp promoter of cotton leaf curl virus (CLCuV) which is found and identified recently suggest that the promoter is not phloem specifically expressed. The expressing activity of gus gene driven by the promoter exists not only in phloem but also in mesophyll tissues and root tip meristem. Transient expression suggests that cp promoter transactivated by AC2 shows expressing activity in mesophyll and vascular tissue of leaf vein.

“PlantNanOmics” is an emerging topic in agricultural research that explores the potential effect of application of nanomaterials on plant growth. Graphene oxide (GO) has excellent properties due to its basal carbon plane and oxygen-containing functional groups. In the present work, the antimicrobial activity of GO was exploited to extend the vase life and improve the quality of cut roses (cv. Carola). The results revealed that the cut roses cultivated in low doses of GO (0.1 mg/L) had longer vase life, larger diameter, and better water relations. Microbial contaminations at the basal stem end is the most common reason for stem blockage that causes water stress and early wilting of cut flowers. GO was found to act as a germicide, effectively inhibiting the microbial growth at the cut stem end and improving water uptake and water balance of cut roses. Therefore, GO can serve as a promising preservative to increase the ornamental value of cut flowers.

The Arabidopsis Jasmonate ZIM-domain proteins （JAZs） act as substrates of SCF complex to repress their downstream targets, which are essential for JA-regulated plant development and defense. The bHLH transcription factor MYC2 was found to interact with JAZs and mediate JA responses including JA-inhibitory root growth. Here, we identified another bHLH transcription factor MYC3 which directly interacted with JAZs by virtue of its N-terminal region to regulate JA responses. The transgenic plants with overexpression of MYC3 exhibited hypersensitivity in JA-inhibitory root elon- gation and seedling development. The JAZ-interacting pattern and the JA-induced expression pattern of MYC3 were distinguishable from those of MYC2. We speculate that MYC3 and MYC2 may have redundant but also distinguishable functions in regulation of JA responses.
