Pineapple, an important tropical herbaceous fruit tree, is renowned for its juicy composite fruits and distinctive aroma. Its extensive evolutionary history, primarily driven by vegetative propagation, has led to a highly heterozygous genome that has been difficult to fully resolve. Here, Feng et al. (pages 2208–2225) have successfully assembled the first telomere-to-telomere genome of pineapple, accompanied by a meticulously curated, highquality gene structure annotation. These comprehensive genomic resources provide a complete map for postgenomic research and breeding efforts in pineapple. The cover image features a flowering hybrid F₁plant, the result of a cross between BL and LY, two pineapple varieties used in the study.

Brief Communications

Efficient and transformation-free genome editing in pepper enabled by RNA virus-mediated delivery of CRISPR/Cas9^free

Chenglu Zhao, Huanhuan Lou, Qian Liu, Siqi Pei, Qiansheng Liao, Zhenghe Li

Tomato spotted wilt virus-mediated delivery of CRISPR/Cas9 bypasses the need for stable transformation and permits efficient, DNA-free genome editing in pepper. Remarkably, up to 77.9% of regenerated pepper plants contained heritable edits. This method has been validated with two pepper varieties and is compatible with existing tissue culture protocols.

Abiotic Stress Responses

Simultaneous mutations in ITPK4 and MRP5 genes result in a low phytic acid level without compromising salt tolerance in Arabidopsis

Yuying Ren, Mengdan Jiang, Jian-Kang Zhu, Wenkun Zhou, Chunzhao Zhao

Engineering of crops with low phytic acid (InsP₆) often impairs other agronomic traits. Simultaneous mutations in the inositol 1,3,4-trisphosphate 5/6-kinase gene ITPK4 and the ABC transporter gene MRP5 result in reduced InsP₆ content without affecting plant salt tolerance, providing a promising strategy for breeding crops with low InsP₆.

STOP1 regulates CCX1-mediated Ca²⁺ homeostasis for plant adaptation to Ca²⁺ deprivation

Wen Hao Tian, Wen Yan Cai, Chun Quan Zhu, Ya Li Kong, Xiao Chuang Cao, Lian Feng Zhu, Jia Yuan Ye, Jun Hua Zhang, Shao Jian Zheng

Calcium ion deficiency induces nuclear accumulation of the transcription factor STOP1, which directly activates the expression of CATION/CALCIUM EXCHANGER1, thus facilitating calcium efflux from the endoplasmic reticulum to the cytosol to maintain calcium homeostasis in Arabidopsis.

The combination of a microbial and a non-microbial biostimulant increases yield in lettuce (Lactuca sativa) under salt stress conditions by up-regulating cytokinin biosynthesis^open

Patricia Benito, Marina Celdrán, Javier Bellón, Vicente Arbona, Miguel González-Guzmán, Rosa Porcel, Lynne Yenush, José M. Mulet

The combination of a microbial and a non-microbial biostimulant increased yield of lettuce under salt stress. Application of the non-microbial biostimulant triggered an abscisic acid-dependent response and, when applied with the microbial biostimulant, potentiated the responses triggered by the microbial biostimulant and elicited a cytokinin-dependent response.

Plant Biotic Interactions

SERKs serve as co-receptors for SYR1 to trigger systemin-mediated defense responses in tomato^open

Hyewon Cho, Dain Seo, Minsoo Kim, Bo Eun Nam, Soyoun Ahn, Minju Kang, Geul Bang, Choon-Tak Kwon, Youngsung Joo, Eunkyoo Oh

The peptide hormone systemin induces the association between its receptor, SYSTEMIN RECEPTOR1 and somatic embryogenesis receptor-like kinases (SlSERKs), triggering their mutual trans-phosphorylation and the phosphorylation of the receptor-like cytoplasmic kinase TPK1b, thus promoting defense responses against herbivorous insects in tomato.

Fusarium graminearum effector FgEC1 targets wheat TaGF14b protein to suppress TaRBOHD-mediated ROS production and promote infection

Shengping Shang, Yuhan He, Qianyong Hu, Ying Fang, Shifeng Cheng, Cui-Jun Zhang

The fungal pathogen Fusarium graminearum delivers the effector FgEC1 into wheat cells, where it indirectly promotes degradation of the reactive oxygen species-producing enzyme TaRBOHD, thus reducing TaRBOHD-mediated reactive oxygen species production, and promoting infection. Overexpression of a target of FgEC1 increased wheat tolerance to F. graminearum without reducing yield.
