“…Interestingly, coffee meiosis coincides with the Brazilian winter, marked by drought and low temperatures, a period of reduced growth of FBs, interpreted as dormant or latent (reviewed by López et al, 2021). A discussion about this terminology is provided by Considine and Considine (2016), but here we adopt the term “latent” because there is no evidence of the physiological basis of coffee dormancy (López et al (2021)…”

“…Compared to established classifications of coffee floral development, these meiosis stages are recognized in the G3 and G4 stages following Morais et al (2008) and in Stage 4 following de Oliveira et al (2014).

Recently, the siRNAs pathways, and especially reproductive phasiRNAs, have attracted attention in eudicots since their biological roles are still unknown and their biogenesis took different evolutionary pathways compared to monocots. In this work, we used Coffea arabica L., a recent allotetraploid formed from the hybridization of Coffea canephora and C. eugenioides unreduced gametes, to explore microsporogenesis and small RNAs‐related pathways in a eudicot crop. First, we identified the microsporogenesis stages during anther development revealing that pre‐meiosis occurs in anthers of 1.5 mm inside floral buds (FBs), whereas meiosis between 1.5 and 4.2 mm FBs, and post‐meiosis in FBs larger than 4.2 mm. These stages coincide with the Brazilian winter, a period of FBs reduced growth which suggests temperature sensitivity. Next, we identified and quantified the expression of reproductive 21‐ and 24‐nt phasiRNAs during coffee anther development together with their canonical and novel miRNA triggers, and characterized the DCL and AGO families. Our results showed that the pattern of reproductive phasiRNA abundance in C. arabica is unique among described eudicots and the canonical trigger car‐miR2275 is involved in the processing of both 21‐ and 24‐nt phasiRNAs. Fourteen DCL genes were identified, but DCL5, related to phasiRNA biosynthesis in monocots, was not, according to its specificity for monocots. Thus, our work explored the knowledge gap about microsporogenesis and related siRNAs pathways in coffee, contributing to the control of reproductive development and the improvement of fertility in eudicots.

“…Endogenous factors influence, for example, morphological and anatomical chemical construction, such as the content of carbohydrates, water, minerals, nutritional status, and growth hormone. Environmental factors influence include air temperature, air humidity, rainfall intensity, light intensity, photoperiod, and canopy position (Zanne et al 2015;Yan et al 2019;Lopez et al 2021). (viii) Further research related to the simulation model of A. luzonensis plants on the influence of climate factors on plant phenology.…”

Abstract. Lestari DA, Ningrum LW, Nada FMH, Pradipta NN, Harsono DR. 2023. Flowering and fruiting phenology of Anaxagorea luzonensis A. Gray (Annonaceae). Biodiversitas 24: 784-792. Anaxagorea luzonensis is one of the critical plant collections from the Annonaceae family, with only one specimen in Purwodadi Botanic Garden (PBG). In protecting these plants, it is necessary to know the process of flowering and fruiting through the phenological process. This research is expected to observe plant propagation, physiology, environmental response, and increased reproductive success. The aim of this research is to know the details of flowering and fruiting phenology stages, determine reproductive success, and explain the floral biology of A. luzonensis. Research on the flowering and fruiting phenology of A. luzonensis was carried out from December 2021 – November 2022 in one season at PBG. The method is observative, including changes in color, shape, and size of flowers and fruit in each phenological stage. In addition, the method includes the count of reproductive success and observation of the A. luzonensis flower. This study's results stated that the flowering and fruiting phenology of A. luzonensis experienced a shorter flowering time than fruiting time and a low percentage (<30%) of reproductive success. Flowering stages are divided into five stages, i.e. initiation, flower bud, before bloom, bloom, and anthesis; fruiting stages are divided into three stages, i.e. immature-sized, mature-sized, and ripe fruit, which occurred in period 73-121 ± 85 days. Environmental and genetic factors cause the low value of reproductive success. This research can be useful for the conservation strategy of A. luzonensis, especially for reproduction biology and seed conservation.
