Sparse Model Identification and Learning for Ultra-high-dimensional Additive Partially Linear Models [PDF]
Journal of Multivariate Analysis, 2019, 2018 The additive partially linear model (APLM) combines the flexibility of nonparametric regression with the parsimony of regression models, and has been widely used as a popular tool in multivariate nonparametric regression to alleviate the "curse of dimensionality".

MULTI-FLORET SPIKELET 4 (MFS4) Regulates Spikelet Development and Grain Size in Rice
Rice Science, 2021 In rice, the spikelet is the basic unit of inflorescence, and its development is important for determining the grain yield and quality. We reported a rice spikelet mutant multi-floret spikelet 4 (mfs4) which resulted in the production of extra floral ...

Development and Evolution of Unisexual Flowers: A Review
Plants, 2022 The development of unisexual flowers has been described in a large number of taxa, sampling the diversity of floral phenotypes and sexual systems observed in extant angiosperms, in studies focusing on floral ontogeny, on the evo-devo of unisexuality, or ...

Diff2Dist: Learning Spectrally Distinct Edge Functions, with Applications to Cell Morphology Analysis [PDF]
arXiv, 2021 We present a method for learning "spectrally descriptive" edge weights for graphs. We generalize a previously known distance measure on graphs (Graph Diffusion Distance), thereby allowing it to be tuned to minimize an arbitrary loss function. Because all steps involved in calculating this modified GDD are differentiable, we demonstrate that it is ...

The WIGGUM gene is required for proper regulation of floral meristem size in Arabidopsis [PDF]
, 1998 The study of cell division control within developing tissues is central to understanding the processes of pattern formation. The floral meristem of angiosperms gives rise to floral organs in a particular number and pattern.

Sizing Up the Floral Meristem [PDF]
Plant Physiology, 1996 About 200 years ago, the poet and naturalist Goethe (1790) suggested that flowers were modified shoots and floral organs were modified leaves. In 1991, this assertion was spectacularly confirmed by Bowman et al., who showed that they could transform the sepals, petals, stamens, and carpels of Arabidopsis flowers into leaf-like organs simply by ...

Active suppression of a leaf meristem orchestrates determinate leaf growth
eLife, 2016 Leaves are flat determinate organs derived from indeterminate shoot apical meristems. The presence of a specific leaf meristem is debated, as anatomical features typical of meristems are not present in leaves.

The CLAVATA and SHOOT MERISTEMLESS loci competitively regulate meristem activity in Arabidopsis [PDF]
, 1996 The CLAVATA (CLV1 and CLV3) and SHOOT MERISTEMLESS (STM) genes specifically regulate shoot meristem development in Arabidopsis. CLV and STH appear to have opposite functions: c1v1 and Clv3 mutants accumulate excess undifferentiated cells in the shoot and

Multiple feedback loops through cytokinin signaling control stem cell number within the Arabidopsis shoot meristem [PDF]
, 2009 A central unanswered question in stem cell biology, both in plants and in animals, is how the spatial organization of stem cell niches are maintained as cells move through them.

Characterisation of inflorescence development in Zea mays with four developmental mutants : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biological Science at Massey University, Palmerston North, New Zealand [PDF]
, 2000 The genetic control of inflorescence development has been studied in great detail in the model dicotyledonous plants Arabidopsis thaliana and Antirrhinum majus. In contrast, little is known about the genetic regulation in monocotyledonous species.
