“…This is possibly related to the temperate climate of the natural habitat of iron walnuts in southwest China, mainly in Yunnan province [ 23 , 24 ]. Walnut species are distributed and cultivated in widely diverse ecologically regions in different climate areas in the world [ 20 , 21 , 22 , 25 , 26 , 27 ]. Previous reports showed that CBFs activate many downstream genes, and ICE1 acts upstream to regulate CBFs, which increases cold stress in plants [ 66 ].…”

“…Persian walnuts and iron walnuts are also used as timber tree species for their high-quality wood [ 20 , 21 , 23 ]. It is commonly known that the flowering and pollinating time of walnuts is in late spring [ 26 , 27 ]. However, there is a limitation for pollinating quality and walnut yield in temperate regions where temperatures can plunge rapidly in the period of late spring frost (cold shock), especially in northern areas [ 28 , 29 , 30 ].…”

Cold stress impacts woody tree growth and perennial production, especially when the temperature rapidly changes in late spring. To address this issue, we conducted the genome-wide identification of two important transcription factors (TFs), CBF (C-repeat binding factors) and ICE (inducers of CBF expression), in three walnut (Juglans) genomes. Although the CBF and ICE gene families have been identified in many crops, very little systematic analysis of these genes has been carried out in J. regia and J. sigillata. In this study, we identified a total of 16 CBF and 12 ICE genes in three Juglans genomes using bioinformatics analysis. Both CBF and ICE had conserved domains, motifs, and gene structures, which suggests that these two TFs were evolutionarily conserved. Most ICE genes are located at both ends of the chromosomes. The promoter cis-regulatory elements of CBF and ICE genes are largely involved in light and phytohormone responses. Based on 36 RNA sequencing of leaves from four walnut cultivars (‘Zijing’, ‘Lvling’, ‘Hongren’, and ‘Liao1’) under three temperature conditions (8 °C, 22 °C, and 5 °C) conditions in late spring, we found that the ICE genes were expressed more highly than CBFs. Both CBF and ICE proteins interacted with cold-related proteins, and many putative miRNAs had interactions with these two TFs. These results determined that CBF1 and ICE1 play important roles in the tolerance of walnut leaves to rapid temperature changes. Our results provide a useful resource on the function of the CBF and ICE genes related to cold tolerance in walnuts.

“…On the other hand, compared to the qualitative traits, the quantitative traits with polygenic control were more sensitive to local environmental conditions [ 6 ]. Previous studies also found that leaf budbursts and flowering habits in walnut were significantly influenced by the environment [ 53 ], as well as the pellicle color [ 8 ] and water-use efficiencies [ 54 ]. For this study, the sampling location Guizhou Province was situated in a low-latitude subtropical region on the Yunnan–Guizhou Plateau in China, which is home to a humid subtropical monsoon climate.…”

“…Yu et al reported that FER was a positive regulator of auxin-promoted growth, to suppress the abscisic acid (ABA) response through the activation of a negative ABI2 regulator of ABA signaling [ 67 ]. In another GWAS panel for walnut [ 53 ], the FER gene was identified as temporally mediating leaf budburst, reflecting its essential role in the regulation of walnut development.…”

Background Understanding the underlying genetic mechanisms that drive phenotypic variations is essential for enhancing the efficacy of crop improvement. Persian walnut (Juglans regia L.), which is grown extensively worldwide, is an important economic tree fruit due to its horticultural, medicinal, and material value. The quality of the walnut fruit is related to the selection of traits such as thinner shells, larger filling rates, and better taste, which is very important for breeding in China. The complex quantitative fruit-related traits are influenced by a variety of physiological and environmental factors, which can vary widely between walnut genotypes. Results For this study, a set of 101 Persian walnut accessions were re-sequenced, which generated a total of 906.2 Gb of Illumina sequence data with an average read depth of 13.8× for each accession. We performed the genome-wide association study (GWAS) using 10.9 Mb of high-quality single-nucleotide polymorphisms (SNPs) and 10 agronomic traits to explore the underlying genetic basis of the walnut fruit. Several candidate genes are proposed to be involved in walnut characteristics, including JrPXC1, JrWAKL8, JrGAMYB, and JrFRK1. Specifically, the JrPXC1 gene was confirmed to participate in the regulation of secondary wall cellulose thickening in the walnut shell. Conclusion In addition to providing considerable available genetic resources for walnut trees, this study revealed the underlying genetic basis involved in important walnut agronomic traits, particularly shell thickness, as well as providing clues for the improvement of genetic breeding and domestication in other perennial economic crops.

“…sesquipedalis (L.) Verdc. is commonly known as asparagus bean, Chinese long bean, long-podded cowpea, pea bean, snake bean or yardlong bean, and is one of the horticultural plants belonging to the legume group which is very important with rich nutritional value [13]. Yardlong bean is also considered one of the most important vegetable crops in parts of Indonesia, Thailand, Philippines, Taiwan, and China [21].…”

One of the legume plants with development potential is the yardlong bean. Because they have a high anthocyanin content, yardlong bean red pods are crucial for maintaining human health. There are multiple red-purple pod lines as a result of the crossing of the two parents purple pod and green pod. The purpose of this study was to assess the yield component of bean lines that were thirteen yards long. The study was carried out in Tembalang, Semarang, Central Java’s Agrotechno Park. Using genotype as the only component, the experiment used a randomized complete block design (RCBD). Agronomic characteristics such as harvesting time, number of pods, pod weight, length, number of seeds per pod, and weight of 1000 seeds were observed. The result showed that one genotype from F7 generation FPT A 3-4-10-1 had superior characters compared to the cultivar check in harvesting time, the number of pods, pod weight, and the number of seeds per pod. The agronomic characters that has been characterized can be may be used as potential donors for future hybridization programs to develop superior yard long bean variety with good yield components.
